  • [Transliterated title] Tumor carcinoide bronquial y apendicular.
  • BACKGROUND: Carcinoid tumor (CT) is an unusual neoplasm observed in several locations and associated with the production of vasoactive substances and occasionally with carcinoid syndrome (flushing, diarrhea, wheezing).
  • Seven of these tumors were localized at the tip of the appendix and measured 2 cm or less.
  • In one patient, the tumor was located at the cecum and measured 3.5 cm.
  • None of the patients showed symptoms of carcinoid syndrome.
  • All the patients are currently disease-free.
  • CT associated with carcinoid syndrome is exceptional in pediatric patients.

  • [Title] Appendectomy or right hemicolectomy in the treatment of appendiceal carcinoid tumors?
  • AIMS AND BACKGROUND: Carcinoids of the appendix continue to be of interest, despite their low incidence.
  • There is still considerable controversy surrounding these tumors, especially with regard to the role of right hemicolectomy in the surgical management.
  • The clinical data were reviewed for demographic details, tumor size, localization in the appendix, histological patterns and surgical procedures.
  • RESULTS: Seven patients (0.9% of all appendectomies) were reported to have carcinoid tumors of the appendix.
  • None suffered from the carcinoid syndrome.
  • The site of the tumor was the apex of the appendix in 4 cases, the body in 2 cases and the base in 1 case.
  • Mean tumor diameter was 8 mm (range, 5-29 mm); in 6 patients it was <2 cm.
  • Treatment was appendectomy in all cases; additional right hemicolectomy was necessary in one case because of a tumor of more than 2 cm with invasion of the mesoappendix and lymph nodes.
  • Six patients are without disease, while 1 patient (the one who underwent a right hemicolectomy) developed metastases in the liver 6 years after the operation.
  • CONCLUSIONS: According to current guidelines, an appendectomy may be performed for small carcinoid tumors (<1 cm).
  • Reasons for more extensive surgery than appendectomy are tumor size >2 cm, lymphatic invasion, lymph node involvement, spread to the mesoappendix, tumor-positive resection margins, and cellular pleomorphism with a high mitotic index.
  • Tumor size is still considered the most important prognostic factor, with a presumed increase in the risk of metastasis for tumors greater than 2.0 cm.
  • The accepted treatment of such tumors is a right hemicolectomy.
  • However, there is no evidence demonstrating a survival benefit for right hemicolectomy over simple appendectomy in patients with carcinoids greater than 2.0 cm in diameter.

  • [Title] Genetic differentiation of appendiceal tumor malignancy: a guide for the perplexed.
  • OBJECTIVE: To use differential gene expression of candidate markers to discriminate benign appendiceal carcinoids (APCs) from malignant and mixed cell APCs.
  • SUMMARY BACKGROUND DATA: Controversy exists in regard to the appropriate surgical management of APCs since it is sometimes difficult to predict tumor behavior using traditional pathologic criteria.
  • METHODS: Total RNA was isolated using TRIzol reagent from 42 appendiceal samples, including appendiceal carcinoids identified at exploration for appendicitis (no evidence of metastasis; n = 16), appendicitis specimens (n = 11), malignant appendiceal tumors (> 1.5 cm, evidence of metastatic invasion; n = 7), and mixed (goblet) cell appendiceal adenocarcinoids (n = 3), normal appendiceal tissue (n = 5), and 5 colorectal cancers.
  • RESULTS: CgA message was elevated (> 1000-fold, P < 0.05) in all tumor types.
  • MAGE-D2 and MTA1 message were significantly elevated (> 10-fold, P < 0.01) in the malignant and goblet cell adenocarcinoid tumors but not in the appendicitis-associated carcinoids or normal mucosa.
  • The apoptotic marker, NALP1, was overexpressed (> 50-fold, P < 0.05) in the appendicitis-associated and malignant appendiceal carcinoids but was significantly decreased (> 10-fold, P < 0.05) in the goblet cell adenocarcinoids.
  • Elevated CgA transcript and protein levels indicative of a carcinoid tumor were identified in one acute appendicitis sample with no histologic evidence of a tumor.
  • CONCLUSIONS: These data demonstrate that malignant APCs and goblet cell adenocarcinoids have elevated expression of NAP1L1, MAGE-D2, and MTA1 compared with appendiceal carcinoids identified at surgery for appendicitis.
  • This and the differences in NALP1 gene expression (decreased in goblet cell adenocarcinoids) provide a series of molecular signatures that differentiate carcinoids of the appendix.
  • CgA identified all appendiceal tumors as well as covert lesions, which may be more prevalent than previously recognized.
  • The molecular delineation of malignant appendiceal tumor potential provides a scientific basis to define the appropriate surgical management as opposed to morphologic assessment alone.

5. Graham RP, Williams NP, West KA: Primary epithelial tumours of the appendix in a black population: a review of cases. World J Gastroenterol; 2009 Mar 28;15(12):1472-4

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Primary epithelial tumours of the appendix in a black population: a review of cases.
  • AIM: To determine the prevalence, histologic types and clinical features of primary epithelial tumours of the vermiform appendix in a predominantly black population.
  • METHODS: All cases of primary tumours of the appendix identified by review of the histopathology records at the University of the West Indies between January 1987 and June 2007 were selected.
  • Non-epithelial tumours were excluded.
  • RESULTS: Forty-two primary epithelial tumours were identified out of 6,824 appendectomies yielding a prevalence rate of approximately 0.62%.
  • Well-differentiated neuroendocrine cell tumours (carcinoids, 47.6%) and benign non-endocrine cell tumours (adenomas, 45.2%) were most common with nearly equal frequency.
  • Carcinoid tumours occurred in younger patients (mean age 32 years), with a male-to-female ratio of 1.2:1.
  • CONCLUSION: Appendiceal epithelial tumours are rare in our experience, and are represented principally by carcinoid tumours and adenomas.
  • Carcinoid tumours occurred in younger patients but were slightly more common in men than women.
  • Tumours were not suspected clinically and were diagnosed incidentally in specimens submitted for acute appendicitis supporting the need for histological evaluation in all resection specimens.

  • AIM: To report the experience of the CHU Sart Tilman, University of Liege, Belgium, in the management of appendiceal carinoid tumor.
  • RESULTS: Among the 1237 appendectomies, 5 appendiceal carcinoid tumors were identified (0.4%) in 4 male and 1 female patients, with a mean age of 29.2 years (range: 6-82 years).
  • All tumors were located at the tip of the appendix with a mean diameter of 0.6 cm (range: 0.3-1.0 cm).
  • All patients were alive and disease-free during a mean follow-up of 33 mo.
  • CONCLUSION: Appendiceal carcinoid tumor most often presents as appendicitis.
  • Appendiceal carcinoid tumor can be managed by simple appendectomy and resection of the mesoappendix, if its size is <or=1 cm.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Combined goblet cell carcinoid and mucinous cystadenoma of the vermiform appendix.
  • Goblet cell carcinoid is an uncommon primary tumor of the vermiform appendix, characterized by dual endocrine and glandular differentiation.
  • Whether goblet cell carcinoid represents a morphological variant of appendiceal classical carcinoid or a mucin-producing adenocarcinoma is a matter of conjecture.
  • Rare cases of goblet cell carcinoid with other concomitant appendiceal epithelial neoplasms have been documented.
  • In this report, we describe a rare case of combined appendiceal goblet cell carcinoid and mucinous cystadenoma, and discuss the possible histopathogenesis of this combination.

  • [Title] Lipid-rich variant of appendiceal well-differentiated endocrine tumor (carcinoid).
  • Well-differentiated endocrine tumors (WDETs) of the appendix show characteristic morphologic features, including proliferation of cells with finely granulated eosinophilic cytoplasm.
  • However, clear cell WDETs, which can present a diagnostic challenge, have been occasionally described, but it is unknown whether they represent a morphologic variant with distinct clinicopathologic features.
  • We studied 13 appendiceal WDETs composed of clear cells, which showed an immunophenotype identical to that of conventional appendiceal WDETs.
  • Patient survival was excellent and equal to that of conventional appendiceal WDETs.
  • These neoplasms, which represent a lipid-rich variant of appendiceal WDETs, do not have different relevant clinical implications compared with conventional WDETs, but it is important to know of their existence for the differential diagnosis with more aggressive neoplasms, including goblet cell carcinoids and appendiceal metastases from clear cell carcinomas.

  • [Title] Analysis of 900 appendiceal carcinoid tumors for a proposed predictive staging system.
  • BACKGROUND: Appendiceal carcinoid tumors (ACTs) are rare, and little is known about the long-term prognosis for these tumors because no staging system exists.
  • DESIGN: Retrospective review of 15 983 patients with carcinoid tumors in the Surveillance Epidemiology and End Results (SEER) database from January 1, 1977, to December 31, 2004.
  • PARTICIPANTS: Nine hundred patients with ACTs (552 females and 348 males; mean age, 47.1 years [age range, 9-89 years]; mean size of the primary tumor, 2.4 cm [range, 0.1-11.5 cm]).
  • RESULTS: Lymph node metastasis was found in 137 patients (24%), and distant metastatic disease in 89 patients (10%).
  • At multivariate analysis, patient age, primary tumor size, histologic features, lymph node involvement, and distant metastasis were significant factors predicting survival.
  • A TNM staging system for ACTs will be helpful not only for physician education about factors that affect the outcome with this disease but also to observe trends in prognosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cervical and endometrial metastases of appendiceal goblet cell carcinoid.
  • Appendiceal goblet cell carcinoid (GCC) is a rare tumor with histologic features of both adenocarcinoma and neuroendocrine tumor (carcinoid).
  • Clinically, it behaves more aggressively than classic appendiceal carcinoid and commonly presents with peritoneal carcinomatosis.
  • We report 2 cases of appendiceal GCC, one with uterine cervical involvement and the other with endometrial involvement as the initial presentations.
  • Primary appendiceal GCC was demonstrated in both cases after systematic clinical investigations.
  • Metastatic appendiceal GCC to uterine cervix and endometrium can potentially be misinterpreted as primary cervical or endometrial signet ring cell carcinoma.
  • Therefore, for any uterine cervical/endometrial signet ring cell carcinoma, a metastatic appendiceal GCC should be considered in the differential diagnosis, especially after excluding other primary sites.

MedlinePlus Health Information. consumer health - Carcinoid Tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Is right hemicolectomy for 2.0-cm appendiceal carcinoids justified?
  • HYPOTHESIS: We believe right hemicolectomy (RHC) is not necessary in patients with an appendiceal carcinoid greater than 2.0 cm.
  • DESIGN: A retrospective review of patients with a histologically confirmed appendiceal carcinoid from April 1, 1980, to February 28, 2005, and an analysis of the literature.
  • PATIENTS: Forty-eight patients (34 females and 14 males) with a histologically confirmed diagnosis of appendiceal carcinoid were included in the study.
  • Appendiceal carcinoid was diagnosed incidentally in all 48 patients.
  • Postoperative follow-up and disease-free survival were confirmed in 33 patients via medical record review.
  • MAIN OUTCOME MEASURES: We assessed the relationship between survival, tumor size, and the role of RHC vs appendectomy alone.
  • RESULTS: Four patients in our series underwent secondary RHC and lymph node dissection for tumors greater than 2.0 cm, and none had positive lymph nodes.
  • Following review of the literature, we were unable to find any recent evidence of distant metastasis from carcinoids in patients already treated by appendectomy.
  • There seem to be no conclusive data to support the notion that RHC confers a survival benefit over appendectomy for carcinoids greater than 2.0 cm.
  • CONCLUSION: Appendiceal carcinoids greater than 2.0 cm can be managed effectively with simple appendectomy, given their low malignant potential and slow growth, obviating the need for RHC in this group of patients without affecting overall survival.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Appendiceal mucinous cystadenoma is a neoplastic complication of IBD: case-control study of primary appendiceal neoplasms.
  • Although IBD frequently involves the appendix microscopically, it is uncertain whether it also predisposes to appendiceal neoplasia.
  • METHODS: We performed a retrospective case-control study of incidental appendiceal neoplasms in colectomy specimens of adults with and without IBD (cases and controls, respectively) based on surgical pathology records spanning 54 months.
  • To minimize referral bias, patients were excluded if they had preoperative clinical evidence or a principal pathologic diagnosis of appendiceal disease.
  • RESULTS: Eleven appendiceal cystadenomas and 6 appendiceal carcinoid tumors were identified among 705 IBD cases (377 ulcerative colitis, 317 Crohn's disease, 11 indeterminate colitis) and 498 non-IBD controls meeting our inclusion criteria.
  • Appendiceal carcinoids were equally prevalent in cases and controls (4/705 [0.6%] versus 2/498 [0.4%], OR 1.4 [95% CI 0.3-7.8]), cases with synchronous neoplasia and controls (1/69 [1.4%] versus 2/498 [0.4%], OR 3.6 [95% CI 0.3-40.8]), and cases with and without synchronous colorectal neoplasia (1/69 [1.4%] versus 3/636 [0.5%], OR 3.1 [95% CI 0.3-30.2]).
  • CONCLUSIONS: IBD with synchronous colorectal dysplasia or cancer is a risk factor for development of appendiceal cystadenomas, implicating this tumor as a neoplastic complication of IBD.
  • IBD does not predispose to the development of appendiceal carcinoids.

  • We report a case of a secondary testicular carcinoid occurring 10 years after surgical treatment of an appendiceal carcinoid.
  • Because secondary carcinoids have a worse clinical course and prognosis than primary tumors, metastatic disease should be excluded before the tumor is identified as a primary.
  • Long-term follow-up is necessary for patients with carcinoid tumor owing to its indolent course and the risk of metastasis several years after treatment of the primary.

  • We analyzed promoter methylation of RASSF1A, CTNNB1, CDH1, LAMB3, LAMC2, RUNX3, NORE1A, and CAV1 using methylation-specific PCR in 33 cases of small bowel carcinoid with both matched primary and metastatic tumors.
  • The methylation status of RASSF1A and CTNNB1 were also determined in six primary appendiceal carcinoid tumors.
  • Immunohistochemical analyses for RASSF1A and beta-catenin were performed in 28 matched primary and metastatic tumors.
  • RASSF1A and CTNNB1 were unmethylated in appendiceal carcinoids.
  • Methylation of RASSF1A and CTNNB1 promoters was more frequent in metastatic compared to primary tumors (p = 0.013 and 0.004, respectively).
  • These results suggest that increased methylation of RASSF1A and CTNNB1 may play important roles in progression and metastasis of small bowel carcinoid tumors.

  • Synchronous and metachronous ovarian and appendiceal mucinous tumors are often the subject of diagnostic consultations in gynecologic pathology practices to address whether the tumors are independent neoplasms or related as primary and metastasis.
  • The ovarian tumors were bilateral in 25 of 28 cases with data on both ovaries and were typically large (mean/median: 14 cm, range: 4.5 to 24.0 cm).
  • The appendices were often firm or thickened but usually did not have a discrete measurable tumor and were not notably enlarged; microscopically, transmural invasion was present in all of them.
  • The ovarian and appendiceal tumors exhibited a variety of patterns of differentiation, including signet ring cell and glandular, with all displaying some goblet cell carcinoidlike patterns (nests, islands, cords, or cryptlike tubules with goblet cells); teratomatous elements were not identified in any ovarian tumors.
  • Chromogranin was expressed in 7 of 19 ovarian tumors (mean/median: 6.3%/0%; range: 0% to 20%) and synaptophysin was expressed in 4 of 18 of these (mean/median: 7.8%/0%; range: 0% to 90%).
  • Chromogranin was expressed in 6 of 16 appendiceal tumors (mean/median: 11.9%/0%; range: 0% to 70%) and synaptophysin was expressed in 6 of 15 of these (mean/median: 16.7%/0%; range: 0% to 90%).
  • Follow-up was available for 25 patients: 17 died of disease at intervals ranging from 4 to 47 months (mean/median: 18/16) and 8 were alive with disease at 1 to 25 months (mean/median: 11/10); median survival was 19 months and the 1-year and 2-year survival rates were 63% and 34%, respectively.
  • The clinicopathologic features of these ovarian tumors indicate they should be labeled as metastatic appendiceal adenocarcinomas rather than as goblet cell carcinoid tumors both to reflect their behavior and help distinguish them from the rare true primary ovarian goblet cell carcinoid tumors.
  • As the ovarian tumors have appreciable components of signet ring cells they qualify as Krukenberg tumors.
  • In cases in which the primary tumor is not already evident, their "goblet cell carcinoidlike" patterns should direct attention to the appendix as a possible source.

  • [Title] [Neuroendocrine tumours of the appendix].
  • According to WHO, neuroendocrine tumors of the appendix (appendiceal carcinoids) are defined as 1. well-differentiated endocrine tumors with benign or uncertain behavior, 2. well-differentiated endocrine carcinoma and 3. goblet cell carcinoma.
  • These tumors are usually diagnosed incidentally during appendectomy.
  • Carcinoid syndrome is rare in appendiceal carcinoid.
  • Tumor size greater than 2 cm is the most important parameter for prognosis.
  • Most patients are cured by appendectomy (appendiceal tumors < or = 2 cm), tumors with a diameter > 2 cm should be managed by right hemicolectomy.

  • [Title] Surgical treatment of appendiceal adenocarcinoid (goblet cell carcinoid).
  • Adenocarcinoid of the appendix is an infrequent tumor with histologic features of both adenocarcinoma and carcinoid tumor.
  • Although its malignant potential remains unclear, adenocarcinoids seem to be biologically more aggressive than conventional carcinoids.
  • The aim of this study was to analyze long-term results of surgical treatment for appendiceal adenocarcinoid.
  • A retrospective review (1991-2003) identified seven patients (median age 72, range 27-81 years) treated for appendiceal adenocarcinoid.
  • Indications for colectomy were tumor size (three cases) associated with appendectomy margin invasion in one case.
  • One patient with lymph node and peritoneal involvement experienced recurrence 9 months after hemicolectomy and died of the disease at 2 years.
  • Five patients were alive without disease at the time of the last follow-up.
  • Our results suggest that appendectomy alone could be used for appendiceal adenocarcinoid provided that the tumor (1) is less than 1 cm;.
  • (3) has less than 2 mitoses/10 high power fields; and (4) has surgical margins that are tumor free.
  • The risk for developing colorectal adenocarcinoma seems to be extremely high in patients treated for appendiceal adenocarcinoid and warrants close follow-up with colonoscopic screening.

  • [Title] Primary appendiceal carcinoma--epidemiology, surgery and survival: results of a German multi-center study.
  • Many retrospective reviews outlined experience from different centers on appendiceal neoplasms.
  • The aim of this study was to analyze the type of surgery and survival of patients with appendiceal malignancies using data from a German multi-center observational study (31 341 patients).
  • METHODS: During a five-year period, 196 consecutive patients with malignant appendiceal tumors were distributed into four groups: appendiceal carcinoids, adenocarcinoma, mucinous adenocarcinoma and adenosquamous carcinoma.
  • Mean age at presentation was youngest for carcinoid tumors.
  • Carcinoid tumors had lowest tumor size and localized disease was present in 72.9%.
  • Overall 5-year survival was 83.1% for carcinoid vs. 49.2% for non-carcinoid tumors.
  • Histological subtype and tumor stage significantly affected survival.
  • CONCLUSIONS: Long-term outcome of carcinoid tumors is superior to non-carcinoid neoplasms.
  • Among all appendiceal neoplasms, adenosquamous carcinoma is the rarest histological subtype which is most commonly associated with advanced tumor stage and worst prognosis.
  • However, the high rate of right hemicolectomy in patients with small carcinoid tumors needs to be critically discussed.

  • However, PAX8 expression has not previously been examined in pancreatic endocrine tumors (PETs).
  • PAX8 expression in other well-differentiated neuroendocrine tumors (WDNETs) was also studied.
  • In total, 190 tumors were evaluated: 156 primary WDNETs (63 PETs, 31 ileal, 5 duodenal, 5 gastric, 19 appendiceal, 13 rectal, and 20 pulmonary carcinoid tumors) and 34 liver metastases (18 PETs and 16 ileal carcinoid tumors).
  • Expression of PAX8 was significantly associated with WHO category 1.1 ("benign" behavior) compared with category 1.2 (uncertain behavior) or 2 (well-differentiated endocrine carcinoma) (positive in 100%, 64%, and 52% of tumors, respectively; P<0.05).
  • PAX8-positive PETs were also significantly smaller and more often clinically functional; PAX8-negative tumors were more frequently associated with liver metastases.
  • PAX8 expression was detected in 0/20 (0%) pulmonary, 1/5 (20%) gastric, 5/5 (100%) duodenal, 0/31 (0%) ileal, 4/19 (21%) appendiceal, and 11/13 (85%) rectal carcinoid tumors.
  • Among the liver metastases, PAX8 was positive in 9/18 (50%) metastatic PETs compared with 0/16 (0%) metastatic ileal carcinoid tumors.
  • In the GI tract, PAX8 is positive in the majority of duodenal and rectal carcinoid tumors, and in a minor subset of appendiceal and gastric carcinoids.
  • PAX8 expression is absent in ileal and pulmonary carcinoid tumors.
  • PAX8 immunostaining may be helpful in determining the primary site for a WDNET metastatic to the liver, as ileal (PAX8 negative) and pancreatic (PAX8 positive) tumors most often present as a metastasis from an occult primary.

  • INTRODUCTION: Appendiceal carcinoids are the most frequent tumors of the appendix and are usually detected as an incidental finding in the final pathology report.
  • The aim of this study was to evaluate the clinical and pathological characteristics, surgical treatment and long-term survival in patients with an appendiceal carcinoid tumor.
  • MATERIAL AND METHODS: We performed a retrospective study of patients treated from 1980 to 2007 with a pathological diagnosis of appendiceal carcinoid tumor.
  • Carcinoid tumor was diagnosed in 40 patients (25 women and 15 men), aged 37+/-18 years old.
  • The tumor was localized in the distal third of the appendix in 24 patients (60%), and the size of the tumor was less than 1cm in 28 (70%).
  • Twenty-nine (72.5%) of these tumors infiltrated the subserosal and/or the serosal layer.
  • CONCLUSIONS: Appendiceal carcinoid tumor is usually detected incidentally in the pathological analysis in patients undergoing surgery for suspected appendicitis.

  • [Title] Carcinoid tumors of the appendix. Prognostic factors and evaluation of indications for right hemicolectomy.
  • BACKGROUND/AIMS: Carcinoid tumors of the appendix are thought to be the most common type of appendiceal neoplasms.
  • Although the vast majority of appendiceal carcinoids behave in a benign fashion, they are considered malignant because they all have the potential for invasion, metastasis and production of physiologically active substances.
  • Also, patients with tumor size more than 1cm underwent a Somatostatin Receptor Scintigraphy (Octreoscan).
  • RESULTS: The most common site for the tumors was the tip of the appendix (18/22).
  • In sixteen patients the tumor size was less than 1cm, in seven patients the tumor diameter was measured to be 1 to 2cm and in one patient the tumor was 3cm.
  • Most of our patients (16/22) underwent only an appendicectomy, while in the rest of them (in the patients with tumor size between 1-2cm and in the patient with invasion of mesoappendix) a right hemicolectomy was performed.
  • No patient was found to have metastatic disease during the operation, while the patient with invasion of the mesoappendix developed metastases in the lung, two years after the operation.
  • CONCLUSIONS: Carcinoid tumors of the appendix, in most cases, are found incidentally during appendicectomies, especially in young females and usually are less than 1cm in size, which is probably the reason of the absence of metastases in all cases.
  • Histological examination and size of the tumor are important factors that contribute to the selection of the surgical treatment and both must be estimated by the surgeons to make the final choice.

  • [Title] Incidental carcinoid tumors of the appendix: do they affect presentation or prognosis?
  • Carcinoid tumors are the most common neoplasm of the vermiform appendix, with most found incidentally after surgery for appendicitis.
  • To determine in patients presenting with appendicitis if incidental carcinoid tumors affected presentation or prognosis, we reviewed our experience.
  • Of 1350 patients receiving an appendectomy from 1992 to 2000 for appendicitis, 20 were found to have appendiceal carcinoid tumors.
  • Comparing tumor patients to 251 consecutive patients whom underwent appendectomy without tumors, we found patients with tumors were older at presentation (41 +/- 4 versus 30 +/- 1 years, P = 0.005) and had initial lower white blood cell (WBC) counts (10.8 +/- 0.8 vs. 14.2 +/- 0.3, P = 0.007).
  • There was equivalent survival between patients with carcinoid and without.
  • Therefore, these data suggest that patients with carcinoid tumors are older and have lower WBC counts at presentation with appendicitis, although outcome was not affected by their presence.

  • [Title] Management of an unexpected appendiceal neoplasm.
  • BACKGROUND: Appendiceal neoplasms are rare and most present unexpectedly as acute appendicitis.
  • METHODS: A systematic literature review was performed to access relevant publications on the presentation, pathology and management of appendiceal tumours.
  • RESULTS: Appendiceal tumours account for 0.4 to 1 per cent of all gastrointestinal tract malignancies and are found in 0.7 to 1.7 per cent of appendicectomy specimens.
  • Carcinoid tumours are most common.
  • Most are cured by simple appendicectomy if the tumour is less than 2 cm in size and does not involve the resection margin or mesoappendix.
  • Epithelial tumours may present with, or in time develop, pseudomyxoma peritonei, the optimal management of which involves complete tumour resection and intraperitoneal chemotherapy, usually available only in specialized centres.
  • CONCLUSION: Suggested algorithms for the management of unexpected appendiceal tumours are provided.
  • Recommendations are made for follow-up of patients with a perforated appendiceal epithelial tumour.

  • Laparoscopic surgery for appendiceal goblet-cell carcinoid (GCC) has only been reported once before.
  • Our patient was incidentally discovered to have an appendiceal tumor and was referred to us for laparoscopy.
  • The tumor involved the body of the appendix and was adherent to the cecum.
  • Histopathology confirmed an appendiceal goblet-cell carcinoid.
  • GCC is a rare tumor of the appendix.
  • Hemicolectomy is indicated in specific situations, such as local involvement or tumor size >2 cm.
  • In our patient, the tumor was adherent to the cecum and tumor size was 5 cm.
  • Laparoscopic surgery for appendiceal tumors is safe, feasible, and even may be beneficial.

  • Malignant carcinoid tumours are the most common accounting for 85% of all appendiceal neoplasms.
  • A retrospective review of all malignant carcinoid tumours diagnosed in our hospital between April 1994 and December 2003 was performed.
  • Nine patients were identified with classical carcinoid tumours (CCT); (M = 3 and F = 6, mean age: 43, range 14-81) and two patients with goblet-cell morphology (F = 2, age 46 and 76).
  • Other appendiceal pathologies were identified following hemicolectomy and oophorectomy.
  • CCT are the most common tumours and have the better prognosis.
  • From our experience and subsequent review of the literature, we recommend right hemicolectomy as the treatment of choice for malignant carcinoid tumours.
  • Following oncological assessment, further adjuvant therapy should be considered for patients with advanced disease.

  • [Title] Surgical treatment of peritoneal carcinomatosis from well-differentiated digestive endocrine carcinomas.
  • BACKGROUND: The presence of peritoneal carcinomatosis (PC) in association with endocrine carcinomas (EC) is generally considered to have no impact on life expectancy, contrary to liver metastases.
  • PATIENTS AND METHODS: Among 111 patients undergoing surgery for progressive, well-differentiated EC, 37 (33%) presented a histologically proven PC, with synchronous liver metastases in 36 of them.
  • The origin was ileal or appendiceal (carcinoid tumors) in at least 81% of cases.
  • CONCLUSIONS: PC associated with EC is not a rare event; it is mainly caused by carcinoid tumors and is always associated with liver metastases.

  • Six tumors were malignant, and the remaining were benign.
  • Two of the four patients with benign tumors died from causes unrelated to the appendiceal neoplasm.
  • The 6 patients with malignant tumors and the other 2 with benign disease were alive and disease free after a mean follow-up of 43 months.
  • Despite the rarity of appendiceal primary tumors, surgeons should be aware of these neoplasms for making correct treatment decisions.
  • We stress the importance of laparoscopic exploration in the management of appendiceal masses.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Goblet cell carcinoid of the appendix: laparoscopic appendectomy or right hemicolectomy?
  • Goblet cell carcinoids are uncommon tumours with histological features of both adenocarcinoma and carcinoid tumour.
  • They occur predominantly in the appendix and although the malignant potential remains unclear, adenocarcinoids appear to be more aggressive than conventional carcinoids.
  • In this case report, we present a goblet cell carcinoid with laparoscopic operative treatment in two stages.
  • Histopathological examination revealed a goblet cell carcinoid with characteristics of aggressive behaviour, indicating the need for laparoscopic right hemicolectomy in which, however, neither residual tumour nor metastatic lymph nodes could be found.
  • As they may present the same clinical presentation, pathological diagnosis is required to distinguish goblet cell carcinoid from acute appendicitis.
  • Two-stage surgery for goblet cell carcinoid is advocated in the literature, but the debate still continues as to whether the goblet cell carcinoid should be treated by appendectomy alone, as for most carcinoids, or by right hemicolectomy, as for the appendiceal adenocarcinoma.

COS Scholar Universe. author profiles.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • CONTEXT: The appendix gives rise to an array of epithelial neoplasms showing glandular or neuroendocrine differentiation, and some tumors with elements of both cell types.
  • Although some appendiceal neoplasms resemble their counterparts in the small and large intestines (conventional adenocarcinoma and carcinoid tumor), the appendix also gives rise to relatively unique entities including mucinous neoplasms and goblet cell carcinoid tumors, which present a challenge in pathologic classification and clinical management.
  • (1) adenocarcinoma, with specific focus on mucinous neoplasm;.
  • (2) goblet cell carcinoid tumor and associated adenocarcinoma; and (3) typical carcinoid tumor.
  • CONCLUSIONS: The most important issue in pathologic assessment of epithelial tumors of the appendix is to understand the clinical implications inherent in the diagnosis.

  • OBJECTIVE: To investigate the pathology, diagnosis,treatment, and prognosis of primary appendiceal tumors.
  • METHODS: The clinical data of 37 patients with primary tumors of the appendix, 16 males and 21 females, aged 56 +/- 13 (35-87) hospitalized Jan.
  • The pathological types included carcinoid tumor (n=12), mucinous tumor (n=17), and adenocarcinoma (n=8).
  • The 1, 3, and 5-year survival rates of the primary appendix carcinoid tumor, mucinous tumor, and adenocarcinoma were 100.0%, 100.0%, and 91.7%, 100.0%, 86.7%, and 71.5%, and 75.0%, 50.0%, and 50.0% respectively.
  • CONCLUSION: A rare disease, appendiceal tumors lack specific clinical features.
  • The prognosis of primary appendix carcinoid tumors is better.

  • A special interest of the senior author in appendiceal and rectal cancer has prompted routine removal of the appendix in all cases undergoing surgery for colorectal cancer.
  • Seven of 169 appendices had abnormalities: 3 mucinous cystadenomas, 2 cystadenocarcinomas, 1 carcinoid tumor, and 1 villous adenoma.
  • Routine postoperative surveillance cannot assess the appendiceal mucosa, so there is little justification for not taking the opportunity to eliminate the possibility of future appendicitis or neoplasia.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Diverticular disease of the vermiform appendix: a diagnostic clue to underlying appendiceal neoplasm.
  • Although the association of appendiceal diverticulosis and neoplasia is known, it remains underemphasized in the teaching and practice of surgical pathology.
  • To investigate the frequency of appendiceal neoplasms with acquired diverticulosis, we conducted a retrospective analysis of all appendectomy specimens received in our institution for a 55-month period (January 2002-July 2006).
  • Eleven (48%) appendectomy specimens with diverticulosis also harbored an appendiceal neoplasm.
  • The association of appendiceal neoplasms with diverticulosis was statistically significant (P < .0001, 2-sided Fisher exact test).
  • Neoplastic processes included 5 well-differentiated neuroendocrine tumors (carcinoids), 3 mucinous adenomas, 1 tubular adenoma, and 2 adenocarcinomas.
  • We stress the need for meticulous gross assessment with histologic examination of the entire appendectomy specimen in cases of appendiceal diverticulosis.
  • Thorough examination is required to rule out an underlying neoplasm as a cause of diverticulosis.
  • As acquired diverticula represent a rare finding, examination of the entire appendix in this setting does not create a significant impact on the workload within the pathologic laboratory.

  • [Title] Large bowel carcinoid tumors.
  • PURPOSE OF REVIEW: Gastrointestinal carcinoids comprise 90% of all carcinoid tumors and all carcinoids have malignant potential.
  • This review focuses on the morphology, prognosis, detection and treatment for appendiceal, colonic and rectal carcinoids.
  • RECENT FINDINGS: Computed tomography exists as an initial examination for the primary carcinoid tumor as well as for metastases.
  • Octreotide scanning has a sensitivity of primary tumor detection of 90%; additionally, I- or I-meta-iodobenzylguanidine scanning and tracer-specific positron emission tomographic scans have demonstrated encouraging results.
  • Further advancements in treatment with tumor-targeted therapy and biochemical evaluation of carcinoids have shown promise.
  • SUMMARY: The recent progress with scintigraphic and radiologic modalities has provided better means for diagnosis of primary and metastatic carcinoid tumors.
  • These newly discovered diagnostic modalities have been more encouraging than the recent treatment approaches that have been studied with regard to metastatic carcinoids.
  • While surgery remains the mainstay of treatment of nonmetastatic carcinoid, there have been studies for various medical treatments of metastatic disease.
  • Unfortunately, there have been disappointing results with regard to improvement of tumor response and patient survival, but a foundation has been established for future trials employing alternative agents and exploration of combination therapies.

  • [Title] Endocrine tumors of the appendix: a pathologic review.
  • CONTEXT: Although rare, appendiceal endocrine tumors are the most common neoplasms of the appendix.
  • OBJECTIVE: To provide recent data that focus on the pathology of endocrine tumors of the appendix including classifications and guidelines for patient management.
  • CONCLUSIONS: Appendiceal endocrine tumors are separated into 2 main groups: classic endocrine tumors and goblet cell carcinoids.
  • Evaluation of their prognoses and risks of malignancy, according to these classifications, depends on several parameters including tumor size, proliferation rate, and infiltration of appendiceal wall and mesoappendix.
  • Most patients with classic endocrine tumors of the appendix have a favorable prognosis.
  • Indications for postappendectomy, complementary surgery, which are still controversial, especially for tumors between 1 and 2 cm, are presented and discussed.
  • In contrast, in patients presenting with a goblet cell carcinoid, a right hemicolectomy after the initial appendectomy is considered the standard surgical intervention.

  • [Title] Clear cell carcinoid of the appendix: an uncommon variant of lipid-rich neuroendocrine tumor with a broad differential diagnosis.
  • The designation of clear cell/lipid-rich refers to an unusual variant of neuroendocrine tumor ("carcinoid") described in several organs, but only recently observed in the appendix.
  • In this study, we report the morphologic, immunohistochemical, and ultrastructural features of an incidentally discovered appendiceal clear cell/lipid-rich carcinoid in a 32-year-old man without any evidence of von Hippel-Lindau disease.
  • Differential diagnosis with mimicking neoplastic and non-tumor lesions, epidemiology, and clinical behavior of this exceedingly rare variant of carcinoid of the appendix are also discussed.

  • [Title] Carcinoid tumors of the appendix: are these tumors identifiable prospectively on preoperative CT?
  • The purpose of this study was to determine if carcinoid tumors of the appendix were identified prospectively on preoperative CT at our institution during the last decade.
  • Pathology reports were reviewed to identify patients in whom an appendiceal carcinoid tumor was identified.
  • Twenty-three carcinoid tumors (1.1%; 15 women [65.2%], eight men [34.8%]; average age 54 years [range, 23 to 86 years]) were identified.
  • No tumors were identified prospectively on CT.
  • Average reported tumor size was 6.1 mm (range, 1.5 to 15 mm; n = 18).
  • A tip or distal location was reported for all tumors for which a location was given (n = 15).
  • Carcinoid tumors occurred in 1.1 per cent of appendix specimens.
  • These tumors were all less than or 1.5 cm in size.
  • Likely as a result of their small size, none of these tumors was identified prospectively on preoperative CT.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cytokeratins 7 and 20 immunoexpression profile in goblet cell and classical carcinoids of appendix.
  • Goblet cell carcinoid (GCC) of the vermiform appendix is an uncommon neoplasm and its histogenesis is controversial.
  • Whether GCC represents a morphological variant of classical appendiceal carcinoid or a mucin-producing adenocarcinoma is still conjectural.
  • Little is known about the immunohistochemical expression of cytokeratins 7 (CK7) and 20 (CK20) in appendiceal neuroendocrine tumors.
  • In this study, we compared the expression of CK7 and CK20 in 17 cases of appendiceal GCC and 25 cases of classical carcinoid.
  • The tumors were also evaluated for Ki-67 proliferation index, mitotic activity, tumor necrosis, extracellular pools of mucin, obvious intestinal type adenocarcinomatous foci, angiolymphatic permeation, perineural/neural infiltration, and the depth of invasion of the appendix wall.
  • Immunohistochemically, all 17 (100%) of GCC exhibited strong and diffuse immunopositivity for CK20, whereas expression of CK7 was present in 12 cases (70.5%), ranging from 5 to 50% of tumor cells being labeled.
  • On the other hand, 25 cases of classical carcinoid tumors were consistently negative for CK7; however, 4 cases (16%) showed immunolabeling for CK20 in 25-50% of the tumor cells.
  • The Ki-67 labeling index in classical carcinoids ranged from 0 to 5%.
  • This study shows that in addition to the morphological differences, GCC (CK7/CK20-positive) and classical carcinoid (CK7/CK20-negative) differ in their expression of CK7 and CK20.
  • Goblet cell carcinoid should be regarded as a crypt cell or an amphicrine carcinoma rather than a variant of carcinoid tumor, a lesion that has benign connotations.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Goblet cell carcinoid tumors (adenocarcinoid) of the appendix.
  • PURPOSE: Goblet cell appendiceal carcinoids represent rare tumors that exhibit histologic features of both adenocarcinomas and neuroendocrine tumors.
  • Ki67 index was greater than 20 percent in all of them, while in only one with local tumor.
  • Combination chemotherapy with either cisplatin plus etoposide or with 5-fluorouracil, cisplatin, and streptozotocin was administered to all patients with metastases resulting in temporary stabilization of disease.
  • Twelve patients are alive, while three died of their disease 9, 13, and 14 months after diagnosis.
  • CONCLUSIONS: The diagnostic value of chromogranin-A, urinary 5-hydroxy-indol-acetic acid, and (111)Indium-labeled octreotide scintigraphy seems to be limited in these tumors.
  • Ki67 index appears to predict tumor behavior.
  • Chemotherapy may have efficacy in metastatic disease, however, more data are required to determine this and the optimal regimen.

  • [Title] LYVE-1 immunocytochemical staining for gastrointestinal carcinoids.
  • AIMS: By immunocytochemical staining for lymphatic vessels using anti-lymphatic vessel hyaluronan receptor (LYVE-1) antibody, pancreatic islets and some pancreatic endocrine tumours (PETs) were positively stained for the cytoplasm in addition to lymphatic vessels.
  • The current study was extended to investigate possible immunostaining of gastrointestinal carcinoids using goat antihuman LYVE-1 antibody.
  • RESULTS: Among 27 gastrointestinal carcinoids, six cases (22%) including five primary and one metastatic carcinoids were positive in the cytoplasm for LYVE-1 in addition to lymphatic vessels and there were abundant lymphatic and blood vessels at the margin of the carcinoids.
  • These six LYVE-1 positive cases consisted of three of 10 small intestinal, one of five appendiceal and two of seven large intestinal carcinoids.
  • CONCLUSIONS: The presence of LYVE-1 immunostaining in some gastrointestinal carcinoids may support a structure-function relationship of lymphatic vessels/hyaluronan receptor for modulating synthesis and secretion of hormones and amines by carcinoid tumour cells.

  • [Title] Immunohistochemical staining for CDX-2, PDX-1, NESP-55, and TTF-1 can help distinguish gastrointestinal carcinoid tumors from pancreatic endocrine and pulmonary carcinoid tumors.
  • Well-differentiated neuroendocrine tumors (WDNET) of the gastrointestinal tract, pancreas, and lung are histologically similar.
  • Thus, predicting the site of origin of a metastasis is not possible on morphologic grounds.
  • In total, 64 gastrointestinal carcinoids (5 stomach; 5 duodenum; 31 ileum; 11 appendix; and 12 rectum); 39 pancreatic endocrine tumors (PET); and 20 pulmonary carcinoid tumors were studied.
  • Ileal carcinoids were exclusively positive for CDX-2 (30/31) and negative for all other markers.
  • Appendiceal carcinoids were uniformly positive for CDX-2 (11/11).
  • All rectal carcinoids were negative for CDX-2 and TTF-1; 2/12 were positive for PDX-1, and 1/12 for NESP-55.
  • The gastric and duodenal carcinoids were only positive for PDX-1 (7/10).
  • TTF-1 positivity was confined to pulmonary carcinoids (7/20); 1/20 was positive for NESP-55; and all were negative for CDX-2 and PDX-1.
  • TTF-1 positivity was confined to pulmonary carcinoids in our study but was present in only about a third of cases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The significance of occult carcinoids in the era of laparoscopic appendectomies.
  • BACKGROUND: We present data acquired in our institution about the incidence of incidental appendiceal carcinoids over a period of 16 years.
  • The possibility of occult carcinoids raises the question of appendectomy of a noninflamed appendix during diagnostic laparoscopy for suspected appendicitis.
  • Outcome measures were the incidence of incidental carcinoids of the appendix found during appendectomies and whether the introduction of laparoscopic appendectomy should alter the surgical management of a normal-appearing appendix.
  • RESULTS: A total of 20 carcinoid appendices were resected by open surgery and 17 by laparoscopy.
  • The diagnosis of a carcinoid tumor was not suspected in any patient before the operation, nor was a tumor identified at the time of the operation.
  • Our data confirm the presence of occult carcinoids in normal-appearing appendices.
  • Further studies are needed to determine the clinical significance of this finding.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Adenocarcinoid tumor of the extrahepatic biliary tract.
  • The term adenocarcinoid was first coined by Warkel et al in 1978 to describe a group of uncommon low-grade malignant appendiceal tumors with morphologic and histochemical evidence of both glandular (adenocarcinoma) and neuroendocrine (carcinoid) differentiation for which several terms have been used in the past.
  • Although the appendix is the most frequent site of this tumor, similar neoplasms have been reported also in other sites, such as colon, gallbladder, Vater's ampulla, and stomach.
  • Provided that it can metastasize, a recent meta-analysis on appendiceal adenocarcinoids showed that right hemicolectomy is not required when the tumor is completely excised and there is no cecal involvement.
  • In this article, the clinicopathologic features of an adenocarcinoid tumor occurring in the extrahepatic biliary tract with infiltration of the common hepatic duct wall that, to the best of our knowledge, represents the first report in this site is described.

  • [Title] Q RT-PCR detection of chromogranin A: a new standard in the identification of neuroendocrine tumor disease.
  • OBJECTIVE: Message and protein expression of CgA was examined to evaluate the sensitivity of a PCR-based approach in the detection of covert neuroendocrine (NE) tissue.
  • SUMMARY BACKGROUND DATA: Immunohistochemical (IHC) measurement of chromogranin A (CgA) discriminates gastrointestinal (GI) carcinoids from epithelial tumors.
  • IHC is, however, an insensitive technique to identify micrometastases or delineate subpopulations of NE cells.
  • METHODS: CgA gene expression was examined by Q-RT PCR in GI carcinoids (small intestinal and metastases, n=17, gastric, n=5), appendiceal tumors (n=10), and adenocarcinomas (gastric, n=5, colorectal, n=6).
  • CgA protein expression levels were quantitatively analyzed following IHC by automated quantitative analysis (AQUA) in 2 tissue microarrays (GI carcinoid and GI adenocarcinoma).
  • RESULTS: CgA gene was overexpressed (P<0.001) in GI carcinoids compared with GI adenocarcinomas and normal mucosa.
  • Elevated levels (P<0.00001) were also identified in carcinoid liver and lymph node (LN) metastases.
  • CgA levels were higher (approximately 2-4-fold) in NE appendiceal carcinoids than in adenocarcinoids, but in GI adenocarcinomas were identical to normal mucosa.
  • CgA protein levels were highest in primary GI carcinoids and in liver metastases and significantly elevated (P<0.005) compared with nonmetastatic lesions.
  • CONCLUSIONS: Overexpression of CgA mRNA and protein in GI carcinoids can identify metastatic cells; thus, PCR for CgA can be used to identify micrometastases not evident by light microscopy or IHC as well as define tumors of ambivalent morphologic phenotype.

  • [Title] Goblet cell carcinoid of the appendix: a specific type of carcinoma.
  • AIMS: Goblet cell carcinoid is a poorly understood tumour of the appendix.
  • The aim of this study was to determine whether it should be regarded as a separate entity or as a variant of classical carcinoid.
  • METHODS AND RESULTS: The immunohistochemical expression pattern of 21 markers and the mutation status of KRas codon 12 were determined in 16 goblet cell carcinoids and compared with 14 classical carcinoids, 19 colonic adenocarcinomas and 10 appendiceal mucinous cystadeno (carcino)mas.
  • Goblet cell carcinoids were significantly different from the control groups.
  • The most important markers for discriminating between the groups were CEA (classical carcinoid versus all others), KRas mutation (present in all mucinous cystadeno (carcino)mas), beta-catenin (goblet cell carcinoid versus left sided colonic adenocarcinoma) and chromogranin (goblet cell carcinoid versus right sided colonic adenocarcinoma).
  • Expression of Math1 and HD5 was similar in goblet cell carcinoid and colonic adenocarcinoma but absent in classical carcinoid.
  • CONCLUSION: The results suggest that goblet cell carcinoids should be regarded as a separate entity.
  • The formerly used term 'crypt cell carcinoma' may be more appropriate because it reflects the more aggressive clinical behaviour of these tumours as well as their greater similarity to adenocarcinomas rather than to carcinoids.

  • [Title] Management of goblet cell carcinoid.
  • BACKGROUND AND OBJECTIVES: Goblet cell carcinoid, a rare tumor of intermediate malignant potential, is known to account for a significant minority of appendiceal neoplasms.
  • Sixteen new cases of gastrointestinal goblet cell carcinoid were reviewed to describe their presentation, treatment, and outcome.
  • RESULTS: Sixteen patients were diagnosed with goblet cell carcinoid between 1995 and 2005.
  • Presenting diagnoses included appendicitis (n=8), abdominal or liver mass (n=5), uterine fibroids (n=1), ovarian mass (n=1), and Crohn's Disease exacerbation (n=1).
  • Patients were divided into two groups: those where the diagnosis was an incidental finding at operation (Group 1) and those where the presentation was of an abdominal mass or metastatic disease (Group 2).
  • CONCLUSIONS: Goblet cell carcinoid is a rare malignant tumor largely affecting the appendix.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Carcinoid tumors are 15 times more common in patients with Crohn's disease.
  • BACKGROUND: The coexistence of intestinal neoplasms with Crohn's disease (CD) has been reported, but the evidence of an increased risk of carcinoid tumor with Crohn's disease has been mixed.
  • We present 4 patients with CD with associated carcinoid tumor.
  • The number of incidental carcinoid tumors in patients who underwent an appendectomy was used as a control.
  • RESULTS: Four cases of carcinoid tumor discovered in patients at resection for CD were identified.
  • None had metastatic disease or carcinoid syndrome.
  • These included 1 cecal (1 mm), 2 appendiceal (3 and 7 mm), and 1 transverse colon (7 mm) carcinoid tumors.
  • None of the carcinoid tumors were identified in regions of active Crohn's disease.
  • The incidence of carcinoid tumor in patients with Crohn's disease was 4 of 111 (3.6%).
  • In comparison, 3 of 1199 patients (0.25%) who had appendectomies were identified as having appendiceal carcinoid tumor.
  • Crohn's disease was associated with an increased incidence of carcinoid tumor; OR 14.9 (95% CI 2.5-102.5), P<0.0001.
  • CONCLUSIONS: There was a significantly increased incidence of carcinoid tumor in our Crohn's patients compared to the control patients.
  • None of the carcinoid tumors developed in areas of Crohn's disease.
  • This suggests that the development of carcinoid tumors may be secondary to distant proinflammatory mediators, rather than a local inflammatory effect from adjacent Crohn's disease.
  • Patients with CD may be at increased risk of developing a carcinoid tumor.

  • [Title] Carcinoid tumors of the appendix in children: experience from a tertiary center in northern Greece.
  • BACKGROUND AND OBJECTIVE: Carcinoid tumors of the appendix are rare in childhood and usually have a benign clinical course.
  • The aim of the study was to report the frequency, clinical presentation, tumor characteristics, and outcome of children with appendiceal carcinoid treated in a pediatric oncology department.
  • Demographics, clinical presentation, tumor characteristics, and follow-up results were recorded.
  • RESULTS: Among 839 admissions, 19 patients (9 boys) with appendiceal carcinoid were identified during the study period.
  • The mean tumor diameter was 4.55 (± 3.45) mm (range 1-15 mm).
  • In 18 children tumor size was ≤ 10 mm and did not infiltrate surrounding tissues.
  • All of the tumors were located at the tip of the appendix and were of the classic histological type.
  • CONCLUSIONS: Carcinoid tumors of the appendix in children are rare.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Developments in diagnosis and treatment of metastatic midgut carcinoid tumors. A review.
  • Carcinoids are neuroendocrine tumours derived from enterochromaffin cells which are widely distributed in the body and may, therefore, arise from any site.
  • Localisation in the gastrointestinal tract is the most frequent, among which the appendiceal involvement is often found at laparoscopy for appendicitis and the small bowel is known for the liver metastases with the production of serotonin causing the characteristic carcinoid syndrome with diarrhoea and flushes.
  • The overall incidence of carcinoid disease has increased in the past decades, but whether this is a true increase or due to early detection or better recognition at pathology is not known.
  • The prognosis of metastatic carcinoid tumours has improved during the last decade resulting in a 5 year survival of approximately 50% in the Netherlands.
  • Due to a longer survival, complications such as carcinoid heart disease and new metastatic patterns like skin and bone metastases may become a more important feature in carcinoid disease.
  • New developments are in the field of diagnostics (fine-tuning of the pathology, videocapsule endoscopy to find the primary tumour, positron emission tomography [PET] scanning) and treatment options (radiofrequency ablation, radioactive octreotide, meta-iodobenzylguanidine combinations).
  • The new serum marker of carcinoid, chromogranin A, may play an important role in the follow-up and NT-proBNP for the detection of heart problems.
  • Combining new diagnostic and treatment modalities in metastatic carcinoid patients may result in a better quality of life and a longer survival.

  • [Title] Composite glandular-endocrine cell carcinoma of the stomach. Report of two cases with goblet cell carcinoid component.
  • Composite glandular-endocrine cell carcinoma (CGECC) is recognized as a special type of gastric tumor composed of ordinary adenocarcinoma and neuroendocrine tumors.
  • Goblet cell carcinoid (GCC) is a well-established type of appendiceal carcinoid, but the GCC component has not been well delineated in CGECC of the stomach.
  • However, the resected tumors consisted of three components: signet-ring cell carcinoma, GCC, and glandular adenocarcinoma.
  • Although some signet-ring carcinoma cells and goblet carcinoid cells were indistinguishable by hematoxylin and eosin staining, E-cadherin immunostaining disclosed a definitive difference regarding the staining pattern in these cells.
  • Both patients are well, with no recurrent tumor for about 10 years of follow-up.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Combined classical carcinoid and goblet cell carcinoid tumor: a new morphologic variant of carcinoid tumor of the appendix.
  • Carcinoid tumors are the most common neoplasms of the appendix.
  • Goblet cell carcinoid has been regarded as a distinctive tumor type, not related to classic carcinoids, and to our knowledge combinations of these 2 tumor types have not been described in detail.
  • In this report, we describe 5 cases of combined classical carcinoid and goblet cell carcinoid (GCC) tumors of the appendix.
  • Four men and 1 woman, (mean age 53.4 y) presented with acute appendicitis (4 cases), whereas 1 presented with a pelvic mass owing to widespread pelvic disseminated disease.
  • The tumors (0.6 to 6.0 cm) were located in the mid-portion and the tip of the appendix.
  • Four patients are alive and asymptomatic, whereas the patient with disseminated pelvic disease died 6 months after surgery.
  • All 5 appendiceal tumors had microscopic features of both classical carcinoid and GCC, either intimately admixed or separate but closely apposed.
  • The extent of the 2 components varied, with classical carcinoid representing 60% to 90% of the tumor.
  • In view of the fact that these combined carcinoid tumors appear to behave more as goblet cell carcinoids, detailed microscopic examination of classical carcinoid tumors of the appendix is suggested and larger series with longer follow-up is required to ascertain the true biologic potential of this unique form of combined carcinoid tumor of the appendix.
  • The occurrence of both carcinoid types in the same appendices suggests a closer histogenetic relationship than previously believed, although the possibility that the 2 components represent separate, independent primaries ("collision tumors") can also be considered.

  • [Title] Current diagnosis and treatment of gastrointestinal carcinoids in a series of 101 patients: the significance of serum chromogranin-A, somatostatin receptor scintigraphy and somatostatin analogues.
  • BACKGROUND/AIMS: Carcinoids are relatively rare tumors that arise from neuroendocrine cells and have proved to be slow growing malignancies which involve many organs and most frequently the gastrointestinal (GI) tract.
  • Herein we present in this study 101 pts with carcinoid tumors that originated from the GI tract and pancreas.
  • The primary tumors originated from the GI tract in 97/101 pts (appendix 34%, small intestine 31%, stomach 14%, duodenum 6%, colon 6%, rectum 3%) and from the pancreas in 4/101 (4%).
  • The diagnosis was confirmed histologically in all cases, after surgical excision of the primary tumor or by biopsies taken during endoscopy.
  • RESULTS: Patients were referred to us with gastrointestinal symptoms or symptoms of the "carcinoid syndrome" (flushing, and diarrhea), depending mainly on the location of the primary tumors and the existence or not of metastases.
  • CgA and 5-HIAA levels were increased especially in metastatic tumors.
  • Localization of the primary tumors to facilitate surgery was made by many imaging techniques (US, CT, MRI, Enteroclysis, OCTREOSCAN) and endoscopic procedures.
  • OCTREOSCAN was positive in 94% pts with metastatic disease.
  • Furthermore, it revealed the primary and the metastatic lesions in 16% and 33% of pts with carcinoids of the small intestine respectively, while other conventional imaging procedures (including MRI) were negative at the same time.
  • Seventy-four percent of the pts underwent a surgical resection of the primary tumor, while in 21%, an endoscopic polypectomy was performed.
  • All pts with metastatic tumors and positive OCTREOSCAN, were treated with Somatostatin analogues, which resulted in control of symptoms (75%), stabilization of tumor growth (71%) or tumor shrinkage (9%).
  • Pancreatic carcinoids and also those that originated from the proximal colon were found to have worst prognosis.
  • CONCLUSIONS: a) Tumor size (especially in appendiceal and gastric carcinoids) and, also, the dispersion of disease, highly predict the evolution of the patients;.
  • b) serum Chromogranin-A seems to be a very useful tumor marker for the diagnosis and follow-up of pts with GI carcinoids;.
  • c) the introduction of new imaging techniques and especially OCTREOSCAN contributes to a better localization of the primary tumors and their metastases, as well as, to the right decision of the appropriate medical treatment;.
  • d) surgical excision is the treatment of choice in nonmetastatic tumors; and e) in pts with metastatic disease, the administration of Somatostatin analogues improves their quality of life.

MedlinePlus Health Information. consumer health - Ovarian Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] From Krukenberg to today: the ever present problems posed by metastatic tumors in the ovary. Part II.
  • This is the second of a two-part consideration of metastatic tumors to the ovary.
  • The first tumor discussed is gastric carcinoma of intestinal-type whose ovarian manifestations have been the subject of a recent paper which emphasized its differences from the Krukenberg tumor.
  • The limited information on spread of tumors of the gallbladder and extrahepatic bile ducts is then reviewed before more detailed consideration of hepatic neoplasms, prompted by recent contributions on hepatocellular carcinoma and intrahepatic cholangiocarcinoma, the latter based on significant experience with this problem in Thailand.
  • The section on appendiceal neoplasms highlights ovarian spread of diverse tumors ranging from typical intestinal-type adenocarcinoma to signet-ring cell carcinomas with various patterns which in the ovary may prompt diagnoses such as a goblet cell (mucinous) carcinoid tumor, but whose ovarian features place them in the category of a Krukenberg tumor.
  • The diverse problems in differential diagnosis of carcinoid tumor (provoked by nested, acinar, and other patterns, including folliclelike spaces) are then reviewed.
  • The section on breast cancer emphasizes that, although usually a manifestation of late stage disease and often not bulky in the ovaries, metastatic breast cancer may form large masses which can represent the clinical presentation.
  • The section on lung tumors largely reflects information in a recent paper that small cell carcinoma and adenocarcinoma are the lung cancers that spread to the ovary most commonly.
  • The extremely broad differential diagnosis posed by metastatic malignant melanoma ranging from that of an oxyphilic tumor, to a small cell tumor, to a follicle-forming neoplasm, is then considered.
  • The endometrial stromal tumors are problematic largely because the history of a primary tumor may be remote, in the ovaries the typical growth and vascular pattern of endometrial stromal neoplasms is not always conspicuous, and some endometrial stromal sarcomas in the ovary show sex cordlike patterns of growth.
  • Recent information has indicated that gastrointestinal stromal tumors may rarely have significant ovarian manifestations and if the primary neoplasm is overlooked, the ovarian tumor may be misdiagnosed, usually as an ovarian fibromatous tumor, but potentially as another primary neoplasm.
  • The final neoplasms considered are malignant mesothelioma and the desmoplastic small round cell tumor.
  • The differential diagnosis of the desmoplastic small round cell tumor is more complex because of the greater overlap with the many other small cell malignant tumors that may involve the ovaries primarily or secondarily.
  • Nonetheless, differences exist in most cases and awareness of the entity should lead to consideration of the desmoplastic neoplasm, particularly in a young female.
  • However, as pointed out in brief concluding remarks, despite the aid of that modality, as in surgical pathology overall, careful consideration of the clinical background, distribution of disease, gross characteristics and spectrum of routine microscopic findings, will lead to the correct diagnosis in the majority of cases and at the very least lead to formulation of a considered differential diagnosis such that use of special techniques may be judicious and those results placed in context of the time-honored clinical and pathologic features.

  • [Title] Co-expression of neuronal intermediate filaments, peripherin and α-internexin in human well-differentiated endocrine neoplasms (carcinoid tumors) of the appendix.
  • The rectum and appendix are the two major sites of well-differentiated endocrine neoplasms (carcinoid tumors) in the lower gastrointestinal tract.
  • Previously, we reported the consistent expression of peripherin in rectal well-differentiated endocrine neoplasms without metastases.
  • However, its expression has not as yet been examined in appendiceal well-differentiated endocrine neoplasms.
  • The aim of our present study was to clarify whether peripherin, a type III neuronal intermediate filament, and α-internexin, a type IV neuronal intermediate filament, are expressed in appendiceal well-differentiated endocrine neoplasms.
  • Other endocrine markers were also examined and compared with the findings from the rectal well-differentiated endocrine neoplasms.
  • The analyses were carried out by immunohistochemical methods using 12 formalin-fixed and paraffin-embedded appendiceal well-differentiated endocrine neoplasms.
  • In addition, immunoreactivity of α-internexin, which was frequently co-expressed with peripherin, was found in all appendiceal cases.
  • Chromogranin A and neural cell adhesion molecule expression was found in all appendiceal tumors, and serotonin was also frequently expressed (83%, 10/12 cases).
  • Incidences of the expression of these three markers were much higher in the appendiceal than in the rectal cases.
  • Peripherin expression is a common feature of appendiceal and rectal well-differentiated endocrine neoplasms, but the manner of neural marker expression is different depending on the site of origin.
  • It is uncertain whether the expression of peripherin and/or α-internexin is present in the well-differentiated endocrine neoplasms of other organs; further analysis is required to clarify this issue.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Appendiceal neoplasms, first described in 1882, are still rare, with pre-operative diagnosis invariably difficult.
  • A literature search of the PubMed database was then performed using the medical search headings; appendix, tumour, neoplasm and malignancy.
  • Eleven patients were found to have carcinoid-type tumours, eight patients with adenocarcinomas and three patients with lymphomas.
  • Other appendiceal pathologies were identified after appendicectomies, hemicolectomy and oophorectomy.
  • Patients with classical carcinoid tumours (CCT) had better outcomes than patients with the goblet cell carcinoid, adenocarcinoma and lymphoma.
  • CONCLUSIONS: From our own experience and a subsequent review of the literature, we recommend right hemicolectomy as the treatment of choice for all malignant appendiceal neoplasms, except for small CCT less than 2 cm in diameter at the tip of the appendix, with a low proliferative index, without angiolymphatic or mesoappendiceal extension.

  • Previously, such lesions have been variously designated as adenocarcinoid, goblet cell carcinoid (GCC), and mixed adenocarcinoma carcinoid.
  • In this study, we undertook a retrospective investigation of 63 such cases and classified them as typical GCC (group A) and adenocarcinoma ex GCC on the basis of the histologic features of the tumor at the primary site.
  • The adenocarcinoma ex GCC group was further divided into signet ring cell type (group B) and poorly differentiated adenocarcinoma type (group C).
  • The clinical characteristics and prognosis were compared within these groups and with conventional de novo appendiceal adenocarcinomas.
  • Both groups A and B tumors shared a similar immunoprofile, which included generally focal immunoreactivity for neuroendocrine markers, and a normal intestinal type mucin glycoprotein profile (negative MUC1 expression and preserved MUC2 immunoreactivity).
  • The proliferative index was relatively low in these tumors and slightly increased from groups A to B tumors (11% to 16%).
  • Both beta-catenin and E-cadherin exhibited a normal membranous staining pattern in groups A and B tumors.
  • The poorly differentiated adenocarcinomas ex GCC (group C) demonstrated abnormal p53 and beta-catenin immunoreactivity.
  • The overall disease-specific survival for all subtypes was 77%, with 46% of patients without evidence of disease and 31% alive with disease.
  • All the patients with clinical stage of I or IIA disease had a favorable outcome after appropriate surgery with or without chemotherapy.
  • Although most patients (63%) with GCC presented at an advanced clinical stage, their clinical outcome could be differentiated by subclassification of tumors.
  • In conclusion, GCC is a distinctive appendiceal neoplasm that exhibits unique pathologic features and clinical behavior.
  • They display a spectrum of histologic features and possess the potential to transform to an adenocarcinoma phenotype of either signet ring cell or poorly differentiated adenocarcinoma types.
  • Careful evaluation of the morphologic features of GCCs and appropriate pathologic classification are crucial for clinical management and prediction of outcome.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Formation of an appendiceal mass or abscess may mitigate against urgent appendectomy during the acute stage, and conservative treatment followed by interval appendectomy has been advocated.
  • RESULTS: Thirty-six children, median age 8 years (range, 1-15 years) diagnosed with appendiceal mass or abscess were offered interval laparoscopic appendectomy by two surgeons in our institution: one patient declined interval laparoscopic appendectomy.
  • CONCLUSION: Interval laparoscopic appendectomy can be safely performed in children, is associated with a short hospital stay and minimal morbidity, analgesia, and scarring following conservative management of appendiceal mass or abscess.
  • Interval laparoscopic appendectomy eliminates the risk of recurrent appendicitis and serves to excise undiagnosed carcinoid tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Goblet cell carcinoid tumor is a rare mixed endocrine-exocrine neoplasm of the appendix.
  • It carries an intermediate biologic behavior between a classic carcinoid tumor and a conventional adenocarcinoma.
  • A recent retrospective study of a large number of appendiceal goblet cell carcinoids has shown that these tumors can be stratified into 3 subgroups based on careful histologic analysis: typical goblet cell carcinoid (group A); adenocarcinoma ex goblet cell carcinoid, signet ring cell type (group B); and adenocarcinoma ex goblet cell carcinoid, poorly differentiated carcinoma type (group C).
  • Thus, meticulous histologic evaluation is of critical importance in determining the prognosis and guiding the management of patients with goblet cell carcinoids.

  • [Title] Neuroendocrine tumours (carcinoids) of the appendix.
  • Neuroendocrine tumours (NETs) of the appendix (formerly 'carcinoids') are rare and are usually detected incidentally after appendectomy.
  • Tumours <1 cm hardly ever metastasize and are treated by appendectomy.
  • Tumours >2 cm require right hemicolectomy because of a significant risk of metastatic spread.
  • Treatment for lesions 1-2 cm is controversial and needs further characterization of the tumour (i.e. mesoappendiceal invasion, vascular invasion, mitotic activity, proliferation markers) and careful patient risk evaluation.
  • Goblet-cell carcinoids have features resembling both carcinoid and adenocarcinoma and should be treated by hemicolectomy.
  • Overall prognosis of small appendiceal NET is excellent in all ages.

  • Malignant tumours of the appendix are rare.
  • They are usually carcinoid tumours that must be distinguished from extremely rare adenocarcinomas.
  • In clinical terms, the tumours usually manifest themselves as acute appendicitis, as ruptured appendicitis, as a tumour in the right lower abdominal quadrant or as a pelvic tumour, which are generally mistaken for an ovarian tumour with the same sonographic image.
  • Surgical therapy of the isolated primary appendiceal carcinoma consists of a hemicolectomy--an appendectomy in favourable cases--and, in the case of a metastasised carcinoma, according to the guidelines for an advanced ovarian or colon carcinoma.

  • [Title] Application of light microscopical and ultrastructural immunohistochemistry in the study of goblet cell carcinoid in the appendix.
  • BACKGROUND: Goblet cell carcinoids appear less frequently in the appendix than do other carcinoids.
  • In the presented work a case with a goblet cell carcinoid of the appendix is described.
  • METHODS: Routine histological and histochemical methods were employed, with a combination of histochemistry and immunohistochemistry on one section and light and electron microscopical immunohistochemisty on paraffin-embedded material, were applied to identify the type of the carcinoid and to reveal the fine structure of cell types in the tumour nests of the appendix.
  • Immunohistochemically the serotonin-, somatostatin-, chromogranin A- and synaptophysin-positive endocrine cells were basally attached to mucin-secreting cells.
  • The combined staining revealed simultaneously present endocrine cells (chromogranin-A-positive) and mucin-secreting cells (PAS- or alcian blue-positive).
  • The ultrastructural immunohistochemistry showed that chromogranin A-positive cells had discoid and pleomorphic granules and were located in tumour nests or as single cells in the appendiceal wall.
  • CONCLUSION: The combined histochemical and immunohistochemical procedure and the ultrastructural immunohistochemistry on archival material could contribute in clarifying the diagnosis of goblet cell carcinoid.

  • OBJECTIVE: To present our experience of carcinoid tumors of the appendix managed at a university teaching hospital.
  • The data of patients identified to have histological evidence of carcinoid tumors of the appendix were further reviewed for the demographic details, indications for surgery, surgical procedure, tumor localization in the appendix and size; concomitant appendicitis and further surgical procedures were considered.
  • RESULTS: During the study period, 1547 appendectomies were performed and, out of these, 9 (0.6%) cases were reported to have carcinoid tumors of the appendix.
  • Six carcinoid tumors were encountered at the appendiceal apex, 2 at the midportion, and one at the base with a mean diameter of 9.5 mm (range, 4-19 mm).
  • One patient had histologically confirmed residual tumor, which necessitated a right hemicolectomy 3 weeks later.
  • All patients remained disease-free during a mean follow up of 7 years (range, 4-10 years).
  • CONCLUSION: Carcinoid tumors of the appendix are extremely rare and invariably remain asymptomatic.
  • Simple appendectomy offers adequate relief while the need for further extensive surgery depends on tumor characteristics and dissemination.

  • [Title] Usefulness of CDX2 and TTF-1 in differentiating gastrointestinal from pulmonary carcinoids.
  • Carcinoids of different organs appear morphologically indistinguishable.
  • We studied the usefulness of differential expression of CDX2 and thyroid transcription factor-1 (TTF-1) in 78 gastrointestinal and pulmonary carcinoids and their metastases (n = 10).
  • All ileal (6/6 [100%]), 6 (86%) of 7 appendiceal, 3 (75%) of 4 duodenal, 1 (50%) of 2 ampullary, 12 (33%) of 18 rectal, 6 (30%) of 20 pancreatic, and 1 (17%) of 6 gastric carcinoids expressed CDX2 with variable intensity; none of the pulmonary carcinoids stained.
  • Of 15 pulmonary carcinoids, 8 (53%) stained with TTF-1, but none of the gastrointestinal carcinoids did.
  • CDX2 and TTF-1 staining profiles of primary and metastatic carcinoids were similar.
  • CDX2+ gastric endocrine cells had a distribution similar to that of gastrin and enterochromaffin cells but not enterochromaffin-like cells.
  • Our results suggest that CDX2 and TTF-1 have high specificity for gastrointestinal and pulmonary carcinoids, respectively.

  • [Title] Carcinoid tumors of the gastrointestinal tract: trends in incidence in England since 1971.
  • OBJECTIVES: The epidemiology of gastrointestinal neuroendocrine tumors (GI-NETs) is poorly understood.
  • Recent analyses have suggested changes in the incidence and distribution of such tumors, but have generally used data sets containing small patient numbers.
  • The anatomic distribution of tumors in the latest period analyzed was stomach 12%, small intestine 29%, appendix 38%, colon 13%, and rectum 8%.
  • Sex-specific incidence rates for gastric, colonic, and rectal NETs are similar, whereas appendiceal lesions were more common in females, and small intestinal tumors in men.
  • In view of the magnitude of these changes, particularly for gastric tumors, further studies to examine the underlying etiology of these changes are urgently indicated.

  • [Title] Primary adenocarcinoid tumor of the ovary arising in mature cystic teratoma. A case report.
  • Primary carcinoid tumors of the ovary are rare, forming 0.3 % of all carcinoid tumors and less than 0.1 % of ovarian malignancies.
  • At laparoscopy, a smooth surfaced, firm and mobile right adnexal mass with solid and cystic portions was detected and the tumor was excised.
  • Pathologic and immunohistochemical examination revealed carcinoid tumor.
  • After the evaluation of gastrointestinal and respiratory systems by imaging and endoscopic studies, no evidence of tumor tissue or metastases were found.
  • Based on this finding, total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and appendectomy were performed and pelvic-paraaortic lymph nodes were also removed.
  • All histological findings were similar to the features of mature cystic teratoma and carcinoid tumor.
  • Examination of the resected lymphatic, omental and appendiceal tissue indicated no tumoral invasion.
  • Thus, the diagnosis was primary ovarian carcinoid arising from a mature cystic teratoma.
  • This case, in the setting of a normal appendix and negative workup for an extraovarian origin, is one of a primary ovarian adenocarcinoid tumor.
  • The primary carcinoid tumor should be differentiated from a metastatic carcinoid inside the ovary, which is always bilateral.
  • It is important to be aware of this unusual entity in diagnoses of ovarian tumors, even in the absence of any clinical symptoms of carcinoid syndrome.

  • [Title] An evaluation of cyclooxygenase-2 as a prognostic biomarker in mid-gut carcinoid tumours.
  • BACKGROUND/AIMS: Mid-gut carcinoids (MGC) are the most common of the gastrointestinal carcinoid tumours.
  • Cox-2 and Bcl-2 were evaluated as prognostic biomarkers in a cohort of well-characterised non-appendiceal MGC.
  • METHODS: Tissue from the primary MGC tumours of 37 patients was subjected to immunohistochemical detection of Cox-2 and Bcl-2.
  • The study assessed whether tumour-associated Cox-2 and Bcl-2 expression were related to patient survival.
  • RESULTS: Cox-2 expression was demonstrated in 30/36 primary tumours.
  • When all tumours were analysed, Cox regression analysis indicated a trend towards worsening survival with increasing Cox-2 histoscore (intensity x proportion; hazard ratio 1.53, 95% CI 0.93, 2.52; p = 0.09).
  • Analysis of Cox-2-positive tumours revealed a highly significant association between increasing histoscore and decreased survival (hazard ratio 3.03, 95% CI 1.33, 6.91; p = 0.008).
  • Tumour-associated Bcl-2 expression had no effect on patient survival (hazard ratio 1.12, 95% CI 0.42, 2.99; p = 0.82).
  • Analysis of the Cox-2 histoscores of primary tumours and their corresponding secondary lesions revealed a statistically significant trend towards increasing histoscore in the latter (Wilcoxon p = 0.04).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • INTRODUCTION: Adenocarcinoid of the appendix is a rare malignant tumour with features of both adenocarcinoma and carcinoid, showing both epithelial and endocrine differentiation.
  • We report a rare combination of these tumours and discuss the latest treatment options.
  • CONCLUSION: Adenocarcinoids account for 2% of primary appendiceal malignancies.
  • Most tumours are less than 2 cm in diameter and 20% of them metastasize to the ovaries.
  • Right hemicolectomy is generally advised if any of the following features are present: tumours greater than 2 cm, involvement of resection margins, greater than 2 mitoses/10 high-power fields on histology, extension of tumour beyond serosa.
  • Chemotherapy mostly with 5-Fluorouracil and Leucovorin is advised for remnant disease after surgery.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Histomorphologic features and routine endocrine immunohistochemical (IHC) markers do not differentiate neuroendocrine tumors (NETs) in relation to their location, making it difficult to establish the site of origin of a metastatic neoplasm.
  • In this study, CDX-2 was expressed in 28/60 (47%) of gastrointestinal NETs with the following results: 11/11 (100%) appendiceal, 12/14 (86%) small intestinal, 3/4 (75%) colonic, 2/11 (18%) rectal, and 0/20 (0%) gastric.
  • TTF-1 was expressed in pulmonary carcinoid tumors in 13/30 (43%) and in 27/30 (90%) pulmonary small cell carcinomas.

  • [Title] The value of 11C-5-hydroxy-tryptophan positron emission tomography in neuroendocrine tumor diagnosis and management: experience from one center.
  • Many neuroendocrine tumors (NET) are small and may escape localization by conventional imaging techniques.
  • Nine patients with clinically, biochemically and/or histologically confirmed NET and negative computerized tomography (CT) or magnetic resonance imaging (MRI), and 111In-pentetreotide (Octreoscan) scintigraphy underwent imaging with 11C-5-HTP-PET/CT in order to:.
  • 1) detect the primary tumor lesion in three patients;.
  • 2) detect residual disease in two patients with appendiceal carcinoid, one with rectal carcinoid, one with midgut carcinoid, and one with ectopic ACTH secretion (EAS) due to residual pulmonary carcinoid; and 3) restage a patient with medullary thyroid carcinoma (MTC) and hepatic metastases.
  • 11C-5-HTP-PET/CT detected lesions in the mediastinum in a patient with EAS due to a pulmonary carcinoid, further hepatic metastases in a patient with carcinoid syndrome (CS) from a NET of unknown primary, further hepatic metastases in the patient with MTC, and hepatic metastases in the patient with midgut carcinoid.
  • The 11C-5-HTP-PET/CT findings contributed to radical cure of the patient with recurrent EAS, and pointed towards bilateral adrenalectomy in the patient with EAS without evident primary tumor.
  • In addition, 11C-5- HTP-PET/CT directed towards combined surgical and medical treatment in the patient with CS and multiple rather than single hepatic metastases and in the patient with midgut carcinoid, and towards continuation of medical treatment in the patient with MTC.
  • 11C-5-HTP-PET/CT is a useful imaging technique, providing additional information for the diagnosis, staging and decision-making regarding management of patients with NET.

  • [Title] Goblet cell carcinoid tumors of the appendix: An overview.
  • Goblet cell carcinoid is an enigmatic and rare tumor involving the appendix almost exclusively.
  • Since its identification in 1969, understanding of this disease has evolved greatly, but issues regarding its histogenesis, nomenclature and management are still conjectural.
  • Various other names have been used for this entity such as adenocarcinoid, mucinous carcinoid, crypt cell carcinoma, and mucin-producing neuroendocrine tumor, although none have been found to be completely satisfactory or universally accepted.
  • The tumor is thought to arise from pluripotent intestinal epithelial crypt-base stem cells by dual neuroendocrine and mucinous differentiation.
  • These may be of signet ring cell type or poorly differentiated adenocarcinoma.
  • Recently molecular studies have shown these tumors to lack the signatures of adenocarcinoma but they have some changes similar to that of ileal carcinoids (allelic loss of chromosome 11q, 16q and 18q).
  • The natural history of GCC is intermediate between carcinoids and adenocarcinomas of the appendix.
  • The most important prognostic factor is the stage of disease.
  • There is some debate about the surgical approach for these tumors, and a summary of published series and recommendations are provided.

  • [Title] Are we missing diagnostic opportunities in cases of carcinoid tumours of the appendix?
  • OBJECTIVE: Carcinoid tumour of appendix is an uncommon condition that can potentially give rise to a variation in management.
  • We aimed to assess the occurrence and mode of presentation of carcinoid tumour of appendix, and any variation of its management.
  • Sixteen (0.82%) patients had carcinoid tumours.
  • The mean age of patients with carcinoid tumour (41.8 years) was significantly higher than those with non-carcinoid pathology (27.7 years) (p = 0.001).
  • The incidence of female patients was higher than the male amongst the carcinoid tumour group (female/male ratio 2.2).
  • None of the carcinoid tumours were identified at operation.
  • Eight patients as well as their general practitioners (53.3%) were unaware of the diagnosis.
  • CONCLUSIONS: Carcinoid tumour of the appendix remains an incidental diagnosis.
  • Patients with carcinoids were significantly older than non-carcinoid conditions.
  • There was a trend of increased occurrence of carcinoids amongst the females.
  • There was a wide variation in involving the multidisciplinary team, conveying the diagnosis to patients as well as their general practitioners, and follow-ups.
