  • [Title] Hepatic resection for metastatic gastrointestinal and pancreatic neuroendocrine tumours: outcome and prognostic predictors.
  • BACKGROUND: Treatment modalities for hepatic metastases from neuroendocrine tumours (NETs) include surgery, somatostatin analogues and arterial embolization.
  • The aims of this study were to evaluate the outcome of patients following surgery and to identify prognostic predictors of recurrent disease.
  • PATIENTS AND METHODS: This was a retrospective clinico-pathological analysis of patients managed with hepatic NET metastases over a 13-year period (January 1994 to December 2006).
  • RESULTS: Eighteen patients with hepatic metastases from NET were identified with a median age of 53 years (range 31-75).
  • The localization of the primary tumour was the terminal ileum (n=8), pancreas (n=7), appendix (n=2) or duodenum (n=1).
  • Twelve patients had synchronous disease and six patients developed metachronous hepatic tumours over a median period of 20 months (range 6-144).
  • The 2- and 5-year disease-free rates following hepatic resection with complete cytoreduction were both 66%.
  • Partial or complete control of endocrine-related symptoms was achieved in all patients with functioning tumours following surgery.
  • Recurrent disease occurred in four patients following complete cytoreductive surgery.
  • Resection margin involvement was associated with developing recurrent disease (p=0.041).
  • CONCLUSION: Surgical resection for hepatic NET metastases results in good long-term survival in selected patients and resection margin involvement was associated with recurrent disease.

8. Wie HJ, Lee JH, Kyung MS, Jung US, Choi JS: Is incidental appendectomy necessary in women with ovarian endometrioma? Aust N Z J Obstet Gynaecol; 2008 Feb;48(1):107-11
PDF icon [Fulltext service] Get downloadable fulltext PDFs of articles closely matching to this article, as many as you want.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Several studies reported that pathology of the appendix is frequently detected alongside endometriosis, especially with chronic pelvic pain.
  • Furthermore, ovarian endometriosis is a marker of more extensive pelvic and intestinal disease.
  • METHODS: One hundred and six women with ovarian endometrioma underwent laparoscopic surgery including laparoscopic appendectomy.
  • RESULTS: The main symptoms consisted of lower abdominal pain in 51 (48.1%) women, dysmenorrhoea in 23 (21.7%), left lower quadrant pain in 6 (5.7%), right lower quadrant pain in nine (8.5%), chronic pelvic pain in five (4.7%), and others in 12 (11.3%).
  • Only three (3.3%) of the 106 women had abnormal findings on gross inspection during laparoscopic surgery: two women with endometriotic spots on the surface of their appendixes, and one with peri-appendiceal inflammation with severe adhesions.
  • Of the 106 resected appendixes, 37 (34.9%) had histopathologically confirmed pathology including lymphoid hyperplasia in 12 (11.3%), endometriosis in 14 (13.2%), peri-appendicitis and serositis in five (4.7%), carcinoid tumour in three (2.8%), and others in three (2.8%).
  • CONCLUSIONS: In all surgical treatments for ovarian endometrioma, surgeons need to preoperatively inform the patients of the fact that appendiceal pathology including endometriosis is found frequently regardless of concurrent symptoms or gross finding of the appendix.
  • Furthermore, surgeons should take into account the possibility of appendiceal pathology during operation.

  • [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).
  • Group 2 included patients presenting with Krukenberg type lesions (n=2) and abdominal masses (n=4).
  • CONCLUSIONS: Goblet cell carcinoid is a rare malignant tumor largely affecting the appendix.

  • [Title] Combined adenocarcinoid and mucinous cystadenoma of the appendix: a case report.
  • INTRODUCTION: Adenocarcinoid of the appendix is a rare malignant tumour with features of both adenocarcinoma and carcinoid, showing both epithelial and endocrine differentiation.
  • Mucinous cystadenoma is the commonest of the benign neoplasms of the appendix, with an incidence of 0.6% in appendicectomy specimens.
  • We report a rare combination of these tumours and discuss the latest treatment options.
  • Laparoscopy revealed an adenocarcinoid of the appendix in combination with mucinous cystadenoma.
  • 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.
  • 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.
  • This brief review summarizes these recent findings and raises a few issues that may need to be further addressed to better apply this classification to our practice.

  • [Title] Surgical treatment of malignant carcinoid tumours of the appendix.
  • Since their first description in 1882, malignant neoplasms of the appendix still remain rare.
  • Malignant carcinoid tumours are the most common accounting for 85% of all appendiceal neoplasms.
  • Preoperative diagnosis is invariably difficult, and precise treatment protocols for these neoplasms remain unclear.
  • 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.
  • However, small CCTs less than 2 cm in diameter at the tip of the appendix, with a low proliferative index, without angiolymphatic or mesoappendiceal extension can be treated by appendicectomy.
  • Following oncological assessment, further adjuvant therapy should be considered for patients with advanced disease.

  • [Title] Carcinoid of the vermiform appendix. Description of three clinical cases and review of the literature.
  • [Transliterated title] Carcinoide dell'appendice vermiforme.
  • Carcinoids of the appendix represent a separate class of tumours with characteristics that vary between benign (adenomas) and malignant (carcinomas) neoplasias.
  • A recent nomenclature identifies them as diffuse neuroendocrine system (DNS) and/or, parallely, as neuroendocrine tumours (NET): the gastroenteric tract is the site of about 64.3% of carcinoids, followed by the respiratory tract with 25.3%.
  • Among the gastrointestinals, tumour of the small intestine is the one with the highest incidence with 28.5%, followed by the appendix with 4.77%, the rectum with 13.6% and the stomach with 4.6%.
  • Carcinoid of the colon has an incidence of 8.62%, with the caecum which alone represents 34.5% of colic localisations.
  • The 3 cases described are an example of the behavioural unpredictability of intestinal carcinoids.
  • The first case is that of a female patient in whom the primary tumour was only discovered after liver metastasis was documented.
  • Subsequent investigations carried out in the postoperative period documented the presence of liver metastasis at the V and VI liver segments.
  • The last case, similar to the second from certain points of view, shows the need to carry out a right hemicolectomy with removal of locoregional lymphnodes in the event of an appendicular carcinoid >2 cm.
  • Both laboratory and instrumental examinations contribute to the diagnosis of intestinal carcinoid.
  • First level instrumental examinations for the diagnosis of intestinal carcinoid are represented by CT with and without contrast medium, diagnostic endoscopy and, to better highlight the presence of locoregional metastases, scintigraphy with octreotide and PET.
  • Treatment with somatostatin, on the other hand, proved effective in controlling tumour secretion, so attenuating the inconveniences of carcinoid syndrome.

  • [Title] Carcinoid tumors.
  • Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that often are indolent and may not become clinically apparent until there has been metastatic spread or evidence of carcinoid syndrome.
  • Recent evidence has revealed that the overall incidence of carcinoid tumors has been steadily increasing, and although the disease was thought to be relatively benign, it is now considered one of increasing malignancy.
  • Carcinoid tumors derive from different embryonic divisions of the gut: foregut carcinoid tumors commonly originate in the lungs, bronchi, or stomach; midgut carcinoid tumors in the small intestine, appendix, or proximal large bowel; and hindgut carcinoid tumors in the distal colon or rectum.
  • Carcinoid syndrome, although rare, is most associated with midgut carcinoid tumors.

  • [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.
  • The most common clinical presentation is acute appendicitis, followed by abdominal pain and a mass.
  • The histologic hallmark of this entity is the presence of clusters of goblet cells in the lamina propria or submucosa stain for various neuroendocrine markers, though the intensity is often patchy.
  • Atypia is usually minimal, but carcinomatous growth patterns may be seen.
  • 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.

  • RESULTS: Miniprobe EUS allowed high-resolution imaging and a successful approach to all colorectal SEL through the working channel of a sigmoidoscope or colonoscope without breakdown of the miniprobe.
  • Thirteen patients, suspected of having rectal carcinoid tumors (mean size, 6.9 +/- 3.3 mm), were treated radically by endoscopic mucosal resection using a transparent cap (EMRC) after EUS confirmation of no muscular invasion.
  • Three patients had no residual or recurrent carcinoid tumor on EUS examination after previous empiric polypectomy or biopsy.
  • Five patients had suspected rectal myogenic stromal tumors on EUS; three were transferred for surgical resection due to uterine myoma compression (N = 2) or mucinous adenocarcinoma of the appendix with rectal metastasis (N = 1), and two had uterine myoma detected by gynecologic ultrasound or CT.
  • One appendiceal stone with orifice obstruction mimicking cecal submucosal tumor was proved by surgical resection.
  • The other six patients had various benign lesions, which were diagnosed and followed-up by EUS without progression.

  • [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.
  • In 1 patient the size was 15 mm and a microscopic rupture of the appendix with infiltration of the surrounding fat was present.
  • All of the tumors were located at the tip of the appendix and were of the classic histological type.
  • No relapses or other neoplasms occurred during a median follow-up period of 45 months (range 6-118 months).
  • CONCLUSIONS: Carcinoid tumors of the appendix in children are rare.

  • [Title] Diverticular disease of the vermiform appendix: a diagnostic clue to underlying appendiceal neoplasm.
  • Acquired diverticula of the vermiform appendix are rare and arise as a result of different pathogenetic mechanisms.
  • One of the etiologies includes proximally located, often unsuspected small neoplasms.
  • 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] Laparoscopic appendectomy after conservative management of appendix mass.
  • The purpose of this study was to demonstrate the safety and efficacy of laparoscopic appendicectomy following non-operative management of appendix mass in children.
  • Medical records of 103 consecutive patients (61 males, 42 females) who underwent non-operative treatment of appendix mass followed by laparoscopic elective appendicectomy were examined.
  • Ten (9.7%) did not respond to initial treatment and developed appendix abscess requiring drainage.
  • Histological examination revealed fibrosed or resolving appendicitis in 52, acute or subacute appendicitis in 24, carcinoid tumour in two and normal appendix in 19.
  • Laparoscopic elective appendicectomy is a safe and effective method of treatment following conservative treatment of appendix mass.
  • Not only does it make the dissection and resection of the appendix easier but it also has the added advantage of performing adhesiolysis.

  • INTRODUCTION: Gastroenteropancreatic neuroendocrine tumors (GEP-NET) are classified on the basis of hormonal activity of tumor cells to functional and non-functional tumors.
  • Therapy of well differentiated NETs includes surgical procedures, debulking of tumor mass, biotherapy and peptid receptor radionuclid therapy.
  • RESULTS: In time period from 1. 1. 2005 to 1.
  • 1. 2010 we followed up 50 pts (19 men/31 women) with well differentiated GEP neuroendocrine tumors.
  • Primary localisation was: stomach--6 times, pancreas--9 times, duodenum--1 times, jejunum-- 4 times, appendix--3 times, ileum--23 times, rectum--4 times.
  • Metastatic disease was affirmed in time of diagnosis in 36 patients.
  • Carcinoid syndroma had 20 pts, 4 pts with pancreatic tumor had functional tumors (2 times overproduction of calcitonine, 1 times of gastrin, 1 times of insuline).
  • Surgical treatment was performed in 40 pts--resection of primary tumor and debulking of metastases, in 5 pts with pancreatic tumor resection was not possible due to invasion to sorrounding tissue and vessels.
  • Biological treatment with long acting somatostatin analogues was indicated in 20 pts with carcinoid syndroma and in 4 pts with functional pancreatic tumors.
  • In 5 pts with non resectable neuroendocrine carcinoma of pancreas peptid radionuclide receptor therapy (PRRT) was indicated: in 4 of them with 90Ytrium-DOTA-octreotid and in 1 patient with MIBG.
  • In all pts a reduction of tumor volume was noticed.
  • Biotherapy with somatostatin analogues reduced symptoms of hormonal activities and brought on stabilisation of disease in most of patients.
  • CONCLUSION: Complex therapy in patients with well differentiated neuroendocrine tumors markedly contributes to prolongation of survival of patients and also to enhancement quality of their life.

  • 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.

  • [Title] Carcinoid tumor of the appendix in childhood: the experience of two Italian institutions.
  • OBJECTIVES: Although rare, carcinoid tumor of the appendix is the most common neoplasm of the gastrointestinal tract in children and adolescents.
  • It is usually an incidental finding after a laparotomy for appendectomy, with a frequency of 2 to 5 cases per 1000 appendectomies.
  • The experience with 14 cases of carcinoid reported in the appendix is described.
  • METHODS AND RESULTS: In six patients the tumor measured 1 cm or less; only in one patient did it measure 2 cm.
  • In three patients the tumor measured between 1 and 2 cm and in four the size was not known.
  • All tumors were discovered by chance, and three patients underwent further surgery as a result of suspected involvement of the margins.
  • All the patients were alive with no evidence of disease at 24 to 214 months from diagnosis.
  • In our experience, both patients with local invasiveness and the patient with a tumor larger than 2 cm had good outcomes.
  • Ileocolectomy performed in the patient with a 2-cm tumor and in another two patients with smaller tumors did not demonstrate residual disease.
  • Although the need for right hemicolectomy still remains controversial for tumors measuring more than 2 cm, the approach may be nonaggressive in case of tumors invading the serosa and the periappendiceal fat.
  • Nonaggressive treatment has been suggested by some authors in cases of tumors larger than 2 cm; however, larger series need to be evaluated.

  • [Title] Carcinoids of the pancreas: an analysis of 156 cases.
  • BACKGROUND: The aim of the current study was to clarify the actual clinicopathologic status of extremely rare pancreatic carcinoids.
  • To date, statistical evaluation of such carcinoids has been hampered because an insufficient number of cases has prevented any reliable statistical analyses.
  • METHODS: The Niigata Registry for Gut-Pancreatic Endocrinomas contains a total number of 156 cases of pancreatic carcinoids among 165 endocrinocarcinomas registered worldwide.
  • This figure of 156 cases comprises 144 typical and 12 atypical carcinoids, which were compared statistically with carcinoids in other representative sites, according to various clinicopathologic criteria.
  • RESULTS: Pancreatic carcinoids made up 1.4% of the total number of registered cases (n = 11,343) and were characteristic in the following five ways.
  • 2) They displayed the largest average tumor size (68.6 mm), followed by that for the ovary (68.2 mm), and ileocecum (46.5 mm) against a total average of 30.2 mm.
  • 3) They revealed a relatively high incidence of the carcinoid syndrome (23.3%), almost equal to that for the ileocecum (24.1%), and exceeded by that for the small intestine (35.8%), when compared with that for the total average of 11.0%.
  • 5) Five-year survival rate was extremely low (28.9% +/- 16.7%) compared with those for the appendix (89.7% +/- 2.0%) and the small intestine (82.1% +/- 3.3%).
  • It was noteworthy that silver impregnations in the pancreatic carcinoid series indicated a result identical to that for the total average: Grimelius argyrophilia, 84.8% versus 85.4%; argyrophil cell type, 59.1% versus 58.5%; and argentaffin cell type, 22.7% versus 22.3%.
  • CONCLUSION: It may be said that in the treatment of patients with pancreatic carcinoids, appropriate procedures should be carried out with these distinguishing characteristics always kept in mind.

  • [Title] [Neuroendocrine tumors of the small intestine and the appendix - management guidelines (recommended by The Polish Network of Neuroendocrine Tumors)].
  • Polish recommendations regarding management of patients suffering from neuroendocrine tumors of small intestine and appendix are presented.
  • Small intestine, especially ileum represent most common origin of these tumors.
  • Rarely, they are less differentiated with fast growth and poor prognosis.
  • In 4-10% of patients typical symptoms of carcinoid syndrome are present.
  • Chromogranin A is useful in the laboratory diagnostics, and urinary excretion of 5-hydroxyindoloacetic acid is helpful for the diagnostics and monitoring of the disease.
  • The treatment of choice in the neuroendocrine tumors of small intestine and appendix is radical or palliative surgery, if possible using endoscopy.
  • The crucial in biotherapy is somatostatin analogs application, possible in symptomatic treatment of hormonally functioning tumors.
  • This is treatment of choice in carcinoid crisis.
  • Interferon alfa could be applied because of the same indications as somatostatin analogs, except for carcinoid crisis.
  • Chemotherapy is less successful in disseminated or locally advanced intestinal neuroendocrine tumors, so radioisotope therapy should be considered in each case of unresectable tumor.

  • [Title] Tachykinins in endocrine tumors and the carcinoid syndrome.
  • OBJECTIVE: A new antibody, active against the common tachykinin (TK) C-terminal, was used to study TK expression in patients with endocrine tumors and a possible association between plasma-TK levels and symptoms of diarrhea and flush in patients with metastasizing ileocecal serotonin-producing carcinoid tumors (MSPCs).
  • METHOD: TK, serotonin and chromogranin A (CgA) immunoreactivity (IR) was studied by immunohistochemistry in tissue samples from 33 midgut carcinoids and 72 other endocrine tumors.
  • Circulating TK (P-TK) and urinary-5 hydroxyindoleacetic acid (U-5HIAA) concentrations were measured in 42 patients with MSPCs before treatment and related to symptoms in patients with the carcinoid syndrome.
  • RESULTS: All MSPCs displayed serotonin and strong TK expression.
  • TK-IR was also seen in all serotonin-producing lung and appendix carcinoids.
  • None of the other tumors examined contained TK-IR cells.
  • Concentrations of P-TK, P-CgA, and U-5HIAA were elevated in patients experiencing daily episodes of either flush or diarrhea, when compared with patients experiencing occasional or none of these symptoms.
  • In a Spearman partial rank test, the correlation of P-TK with daily diarrhea was independent of both U-5HIAA and CgA levels.
  • CONCLUSION: We found that TK synthesis occurs in serotonin-IR tumors and that P-TK levels are significantly correlated with symptoms of flush and diarrhea in patients with MSPCs.
  • This is, to our knowledge, the first report demonstrating an independent correlation of P-TKs with carcinoid diarrhea, a symptom that is customarily regarded as serotonin mediated.
  • Further investigations may present opportunities for new therapeutic possibilities.

  • [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.
  • All patients underwent appendectomy including removal of the mesenteriolum, and in one of them a right hemicolectomy was performed 3 weeks later.
  • 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] 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.
  • Both components stained for the general neuroendocrine markers, however, staining in the classic component was greater.
  • The pelvic soft tissue and ovarian metastases in case 4 consisted predominantly of a signet ring cell carcinoma with a minor component of goblet cells and was interpreted as an adenocarcinoma ex-GCC.
  • 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.

  • RESULTS: A total of 200 patients were included.
  • The tumors were categorized according to their distribution as appendix (n=4), cecum ( n=7), right colon (n=1), hepatic flexure (n=2), transverse colon (n=19), splenic flexure (n=3), left colon (n=6), sigmoid ( n=16), rectum (n=117), rectosigmoid and rectal lesions (n=16), and colorectal lesions without known locations (n=9).
  • Non-mucinous adenocarcinoma (AC) was the most common histological type (n=181, 90%), followed by mucinous AC (n=15), squamous cell carcinoma (n=1), carcinoid (n=1), melanoma (n=1) and signet ring carcinoma (n=1).
  • CONCLUSIONS: We have had few reports with reference to the epidemiology of CRC in Iran since 1977.
  • We found no significant difference between age, gender and type of cancer with subsite distribution.

  • [Title] Goblet cell carcinoid of the appendix.
  • BACKGROUND: Goblet cell carcinoid (GCC) of the appendix is a rare neoplasm that share histological features of both adenocarcinoma and carcinoid tumor.
  • While its malignant potential remains unclear, GCC's are more aggressive than conventional carcinoid.
  • The clinical presentations of this neoplasm are also varied.
  • This review summarizes the published literature on GCC of the appendix.
  • METHODS: Published studies in the English language between 1966 to 2004 were identified through Medline keyword search utilizing terms "goblet cell carcinoid," "adenocarcinoid", "mucinous carcinoid" and "crypt cell carcinoma" of the appendix.
  • RESULTS: Based on the review of 57 published papers encompassing nearly 600 diagnosed patients, the mean age of presentation for GCC of the appendix was 58.89 years with equal representation in both males and females.
  • Accurate diagnosis of this neoplasm requires astute observations within an acutely inflamed appendix as this neoplasm has a prominent pattern of submucosal growth and usually lacks the formation of a well-defined tumor mass.
  • The most common clinical presentations in order of frequency were acute appendicitis in 22.5%; asymptomatic in 5.4%; non-localized abdominal pain in 5.15% and an appendicular mass in 3.09%.
  • GCC's of the appendix remains a neoplasm of unpredictable biological behavior and thus warrants lifelong surveillance for recurrence of the disease upon diagnosis and successful surgical extirpation.
  • CONCLUSION: GCC of the appendix is a rare neoplasm.
  • Due to its wide range of presentation, this tumor should be considered as a possible diagnosis in many varied situations leading to abdominal surgery.
  • The advocated plan of management recommended for patients with tumors that involve the adjacent caecum or with high-grade tumors with histological features such as an increased mitotic rate involve initial appendectomy with completion right hemicolectomy due to the high possibility of local recurrence with intraperitoneal seeding prior to lymph node involvement and a 20% risk of metastatic behavior.
  • In female patients with GCC of the appendix regardless of age, bilateral salpingo-oophorectomy is advocated.
  • In cases with obvious spread of the disease chemotherapy, mostly with 5-FU and leucovorin is advised.

  • [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.
  • We present a case of a 47-year-old woman with abnormal vaginal bleeding and abdominal discomfort.
  • 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] Neuroendocrine tumours (carcinoids) of the appendix.
  • Neuroendocrine tumours (NETs) of the appendix (formerly 'carcinoids') are rare and are usually detected incidentally after appendectomy.
  • They are preferentially located at the tip of the appendix.
  • 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.

  • [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 all the neoplasms examined, diffuse immunoreactivity of peripherin was observed.
  • 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.

  • We evaluated our 10-year experience in the management of GI carcinoid tumors.
  • The records of 133 patients with GI carcinoids were reviewed.
  • The rectum was the most common site for carcinoid tumors with an incidence of 30 per cent followed by jejunoileal at 29.3 per cent.
  • Other sites of carcinoid tumors were the appendix (8.3%), colon (8.3%), and duodenum (3.8%).
  • Endoscopy was the most helpful modality in diagnosing GI carcinoids.
  • CT was not helpful in preoperative diagnosis of carcinoid tumor.
  • Fifteen patients died in follow-up with eight deaths related to carcinoid tumors, in the small bowel (6), rectum (1), and colon (1).
  • Overall survival was 68.7 per cent and mortality rate was 19.5 per cent from carcinoid tumors.
  • Most of the deaths occurred in patients with carcinoid syndrome, synchronous malignancy, and malignant carcinoid tumors.
  • The mean disease-free survival was 51 months (range, 15 to 138 months).
  • Screening colonoscopy, in addition to decreasing colorectal adenocarcinoma mortality, is useful in diagnosing carcinoid tumors at an earlier stage and in decreasing mortality from malignant colorectal carcinoid tumors.

  • [Title] An unusual case of rectal carcinoid removed by transanal endoscopic microsurgery.
  • The name ''carcinoid'' was invented by Oberndorfer in 1907, when the nature of those histological entities was little understood.
  • Usually, they were found in various locations in the gastrointestinal (GI) apparatus (67%), most of them in the small intestine (25%), appendix (12%), and rectum (14%).The techniques used for their removal are various.
  • The authors present here a case of rectal carcinoid removed using the transanal endoscopic microsurgery technique, and referred to the diagnosis and treatment of this uncommon tumor.
  • Complete blood count (CBC) and laboratory data as tumor markers and urinary 5-hydroxyindoleacetic acid (5-HIAA) showed no abnormalities, while urinary vanilmandelic acid level was elevate (18 mg/24 h).
  • The histological finding demonstrated a nodule characterized by cellular proliferation, with few microscopical abnormalities, arranged in small cords with a glandular pattern, separated by dense connective tissue.
  • Histochemically the tumor cells were cytocheratins +/-, chromogranin positive, synaptophysine positive, CD56 positive and Growth Index MIB1-Ki67 which was almost zero.
  • The use of Transanal Endoscopic Microsurgery (TEM) as a safe and feasible technique for exciding rectal tumors can be easily understood, for the excellent view and precise dissection.
  • The use of new surgical devices as Harmonic Scalpel has improved the precision of this kind of approach, increasing the appropriateness of this approach compared to other kind of resection.
  • A full diagnostic course and an immunohistochemistry are mandatory for precise diagnosis of rectal carcinoid.
  • Careful attention must be paid to these tumors because of their unexpected behaviour.

  • PURPOSE OF REVIEW: To guide the clinician in the diagnostic evaluation of endocrine neoplasms, to distinguish between benign and malignant and determine when surgical referral is indicated.
  • RECENT FINDINGS: Thyroid nodules are uncommon but malignant in as many as 27% of patients.
  • Adrenal neoplasms cover a wide spectrum of disorder.
  • Malignant lesions of the adrenal gland carry a poor prognosis when complete surgical resection cannot be achieved.
  • Carcinoids are rare neuroendocrine neoplasms, primarily of the appendix, associated with carcinoid syndrome in 10% of patients.
  • SUMMARY: Endocrine neoplasms are unusual in the pediatric population.
  • Their presence should raise concern about a multiple endocrine neoplasia syndrome and appropriate diagnostic and endocrine work-up.
  • Most neoplasms will require surgical resection.

  • 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] Discordant histology of primary appendiceal adenocarcinoid neoplasms with peritoneal dissemination.
  • BACKGROUND: Adenocarcinoid is a rare appendiceal tumor that shows histologically both epithelial and neuroendocrine components.
  • We observed that some patients have peritoneal dissemination, which shows adenocarcinoma but lacks the neuroendocrine histology.
  • The objective of the present study was to quantitate these discordant histopathological findings and examine its clinical implication.
  • METHODS: Twenty-six patients with peritoneal dissemination from primary appendiceal adenocarcinoid tumors underwent cytoreductive surgery and perioperative intraperitoneal chemotherapy.
  • All resected specimens were individually submitted for histopathological examination and immunostaining with three neuroendocrine markers.
  • The loss of the neuroendocrine tumor type in peritoneal implants was referred to as discordant feature of the adenocarcinoid tumor.
  • RESULTS: In nine of the 26 patients (35%) with a primary adenocarcinoid of the appendix, a loss of the neuroendocrine immunochemical marker was noted in peritoneal implants.
  • Discordant histology between the primary appendiceal adenocarcinoid and the peritoneal implants was statistically significantly associated with an improved survival (p = 0.0262), when patients were treated by cytoreductive surgery and perioperative intraperitoneal chemotherapy.
  • CONCLUSIONS: Discordant histology of the primary appendiceal tumor as compared to the peritoneal lesions occurs frequently in patients with adenocarcinoid.
  • An assessment of neuroendocrine markers in both primary and peritoneal lesions may help in the clinical assessment of this group of patients.

  • The carcinoid tumour of the appendix and the mucocele are entities rather infrequent in children and are normally diagnosed in the course of an appendicectomy that is, in most of the cases, curative.
  • The authors present a case of carcinoid tumour of the appendix associated to mucocele in a male, aged 10 patient, who underwent an appendicectomy by suspicion of an acute appendicitis.
  • The histologic study confirmed the presence of a mucocele of the appendix associated to a carcinoid tumour with a 0,7 cm diameter.
  • The serum serotonin and chromogranin A assessment was normal, and the TAC and colonoscopic examination resulted in no meaningful findings.
  • The appendicectomy itself was curative, deeming it the appropiated treatment in tumours under 2 cm diameter.

  • [Title] Carcinoid tumour of the appendix: an analysis of 1,485 consecutive emergency appendectomies.
  • AIM: The aim of this study is to conduct a retrospective analysis of the incidence and long-term results of carcinoid tumours of the appendix in emergency appendectomies.
  • RESULTS: In three women and four men, carcinoid tumours were identified (0.47%).
  • Four patients underwent ileocecal resection; one other patient underwent right hemicolectomy.
  • In none of the re-operation specimens was residual carcinoid tumour detected.
  • After a mean follow-up of 65 months (range, 25-92), all patients were alive and disease- and symptom-free.
  • CONCLUSION: Carcinoid tumours of the appendix most often present as acute appendicitis.
  • It also emphasises the value of histopathological analysis of every removed appendix.
  • The long-term prognosis of incidentally found carcinoids of the appendix is good.

  • [Title] Laparoscopic versus open resection for appendix carcinoid.
  • BACKGROUND: Since an increasing number of appendectomies are performed via laparoscopy, it is crucial to determine the impact of this approach on appendix carcinoid (AC) outcome.
  • The goal of this study was to compare results of laparoscopic (LAP) versus open (OP) appendectomy for AC according to intend to treat approach.
  • RESULTS: Most cases had associated acute appendicitis (64%).
  • Median carcinoid size was 1.1 cm (range, 0.3-5) and 0.4 cm (range, 0.2-3) in the LAP and OP groups, respectively.
  • Two patients died in the OP group, one due to metastatic carcinoid and the other due to metachronous colorectal cancer.
  • CONCLUSION: Laparoscopic appendectomy is a safe procedure for AC, with carcinologic and long-term results similar to those of conventional appendectomy.
  • Prognosis of AC appears more dependent on carcinoid malignant potential or associated tumors.

  • [Title] Carcinoid and neuroendocrine tumors of the colon and rectum.
  • Carcinoid and neuroendocrine tumors of the colon and rectum arise from the amine precursor uptake and decarboxylation (APUD) cells of the intestine.
  • Carcinoid tumors are most commonly found in the gastrointestinal tract and are located in decreasing order of frequency in appendix, ileum, rectum, stomach, and colon.
  • The management of these lesions depends upon the size of the lesion, involvement of the muscularis, location, and presence of metastatic disease.
  • Adjuvant therapy is indicated only for metastatic disease, and admirable advances have been made in the realm of chemotherapy for reduction of disease and palliation of the symptoms of carcinoid syndrome.
  • In this article, we discuss the nature of these interesting and uncommon tumors, clinical presentation, treatment options, and prognosis.
