[Title] Prognostic factors in primary adenocarcinoma of the small intestine: 13-year single institution experience.

BACKGROUND: Adenocarcinoma of the small bowel is a relatively rare malignancy as compared to the other malignancies of the gastrointestinal tract.

Nonspecific presentation and infrequent occurrence often leads to a delay in diagnosis and consequent poor prognosis.

METHODS: The medical records of a total of 27 patients treated for adenocarcinoma of the small bowel at Providence Hospital and Medical Centers from year 1990 through 2003 were reviewed retrospectively.

RESULTS: The patients included nine males and eighteen females with a median age at diagnosis of 62 years.

Only 48% of the patients had an accurate preoperative diagnosis while another 33% had a diagnosis suspicious of small bowel malignancy.

[Title] Immunophenotype and molecular characterisation of adenocarcinoma of the small intestine.

BACKGROUND: Despite having a dramatically larger surface area than the large intestine, the small intestine is an infrequent site for the development of adenocarcinoma.

To better understand the molecular abnormalities in small bowel adenocarcinoma (SBA), we characterised a number of candidate oncogenic pathways and the immunophenotype of this rare cancer.

CONCLUSIONS: These results suggest that alterations in DNA MMR pathways are common in SBAs, similar to what is observed in large bowel adenocarcinomas.

[Title] Recent advances in the management of adenocarcinoma of the small intestine.

Adenocarcinoma of the small intestine is a rare malignancy with limited data available to guide therapeutic decisions.

Delays in diagnosis are frequent and the majority of patients will present with advanced-stage disease and either lymph node involvement or distant metastatic disease.

Recent retrospective and prospective studies have helped to clarify the optimal chemotherapy approach for advanced small bowel adenocarcinoma.

This article reviews the clinical features and evaluation of patients with small bowel adenocarcinoma and focuses on recent advances in management.

[Title] Clinical analysis of primary anaplastic carcinoma of the small intestine.

Primary anaplastic carcinoma is a rare variant of small intestinal cancer.

Most reports of primary anaplastic carcinoma of the small intestine are isolated case reports, therefore the clinicopathological features, therapeutic management, and surgical outcome of this tumor type remain unclear.

This review analyzes the available clinical characteristics of primary anaplastic carcinoma of the small intestine and investigates key differences from differentiated adenocarcinoma of the small intestine.

A Medline search was performed using the keywords 'small intestine' and 'anaplastic carcinoma' or 'undifferentiated carcinoma'.

The literature revealed a poor prognosis for patients who underwent surgical resection for anaplastic carcinoma of the small intestine, which gave a 3-year overall survival rate of 10.8% and a median survival time of 5.0 mo.

The literature suggests that anaplastic carcinoma is markedly more aggressive than differentiated adenocarcinoma of the small intestine.

Surgical resection with the aim of complete tumor removal provides the only beneficial therapeutic option for patients with anaplastic carcinoma of the small intestine, because chemotherapy and radiation therapy have no significant effect on the rate of survival.

However, despite complete tumor resection, most patients with anaplastic carcinoma of the small intestine are at great risk of disease recurrence.

This report also highlights the importance of a systematic diagnostic approach for anaplastic carcinoma of the small intestine.

[Title] Expression of cyclo-oxygenase 1 and 2, prostaglandin E synthase and transforming growth factor beta1, and their relationship with vascular endothelial growth factors A and C, in primary adenocarcinoma of the small intestine.

BACKGROUND: Primary adenocarcinomas of the small intestine are rare.

METHODS: Expression of cyclo-oxygenase (COX) 1 and 2, prostaglandin E synthase (PGES), TGF-beta1 and vascular endothelial growth factor (VEGF) A and C genes was analysed in 54 primary adenocarcinomas of the small intestine and corresponding normal intestinal mucosa.

COX-1, COX-2, VEGF-A, VEGF-C, PGES and TGF-beta1 mRNA expression varied markedly in different tumours, but all were overexpressed compared with levels in normal intestinal mucosa.

CONCLUSION: Correlations between levels of mRNA for COX-1, COX-2, TGF-beta1 and PGES and those for proangiogenic factors VEGF-A and VEGF-C suggest a role for these factors in the propagation of primary adenocarcinomas of the small intestine.

[Title] Primary adenocarcinoma of the small intestine: presentation, prognostic factors and clinical outcome.

BACKGROUND: Malignant small intestine tumor accounts for 0.1-0.3% of all malignancies.

Although primary adenocarcinoma is the most common histologic subtype, there is no report of the clinical characteristics and natural history in the Asian population.

METHODS: We conducted retrospective analysis for the patients with the small intestine adenocarcinoma to explore the clinical characteristics and prognosis.

All patients with adenocarcinoma of small intestine diagnosed between March 1997 and March 2007 in the Catholic Medical Center in Korea were identified through the cancer registry.

CONCLUSIONS: The prognosis of primary adenocarcinoma of small intestine was poor, especially in cases where curative resection could not to be performed.

[Title] Is there a role for adjuvant therapy in resected adenocarcinoma of the small intestine.

BACKGROUND: The benefit of adjuvant therapy for resected small bowel adenocarcinoma has not been proven.

We undertook a retrospective analysis to evaluate the benefit of adjuvant therapy in a clearly defined patient population with curatively resected small bowel adenocarcinoma.

MATERIAL AND METHODS: We identified 54 patients with small bowel adenocarcinoma who underwent margin-negative surgical resection and were evaluated after surgery at the University of Texas, M. D.

DISCUSSION: The use of adjuvant therapy for curatively resected small bowel adenocarcinoma was associated with an improvement in DFS.

[Title] Adenocarcinoma of the small intestine: a multi-institutional study of 197 surgically resected cases.

Small intestinal adenocarcinoma is a rare malignant neoplasm, and its clinicopathologic characteristics have not been well elucidated.

A total of 197 small intestinal adenocarcinoma cases were collected from 22 institutions in South Korea and were evaluated for clinicopathologic factors that affect the prognosis of small intestinal adenocarcinoma patients using univariate and multivariate analyses.

The median survival time for all small intestinal adenocarcinoma patients was 39.7 months.

Compared with small intestinal adenocarcinomas without accompanying sporadic adenomas, small intestinal adenocarcinomas with accompanying adenomas were more well differentiated (P < .0001), with a more polypoid growth pattern (P < .0001), a lower pT classification (P < .0001), less perineural invasion (P = .01), and less lymphatic invasion (P = .03).

Small intestinal adenocarcinoma patients with associated sporadic adenomas (77%) had a significantly better 5-year survival rate than those without sporadic adenomas (38%, P = .02).

By univariate analysis, small intestinal adenocarcinoma patients had significantly different survival based on pT classification (P = .003), lymph node metastasis (P < .0001), distal location (jejunal and ileal carcinomas) (P = .003), retroperitoneal tumor seeding (P < .0001), vascular invasion (P = .007), lymphatic invasion (P = .001), peritumoral dysplasia (P = .004), and radiation therapy (P = .006).

In conclusion, (1) small intestinal adenocarcinomas are diagnosed at an advanced disease stage; therefore, the development of strategies for detection at an earlier stage is needed. (2) Small intestinal adenocarcinoma patients with an adenomatous component had a better survival than those without an adenomatous component. (3) Lymph node metastasis and distal location (jejunum and ileum) of tumor are the most important independent prognostic factors.

[Title] Impact of lymph node evaluation on survival for small bowel adenocaricnoma: Analysis of the Surveillance, Epidemiology and End Results (SEER) database.

: 4596 Background: Small bowel adenocarcinoma is a rare malignancy and is often associated with poor outcome.

METHODS: Patients aged 18-90 with adenocarcinoma of the small intestine diagnosed between 1988 and 2005 were identified from SEER data (ver. 2008).

CONCLUSIONS: As noted in colon cancer, the total number of LN assessed has considerable influence upon survival in stage I, II and III small bowel adenocarcinoma.

Stratifying stage III small bowel adenocarcinoma into those with <3 and ≥3 positive lymph nodes significantly improves prognostication for these patients and future staging systems should incorporate the number of positive nodes into nodal staging.

[Title] Adjuvant chemotherapy for small intestine adenocarcinoma.

BACKGROUND: Although the small intestine represents 75% of the length and over 90% of the mucosal surface of the alimentary tract, it is the site of only about 2% of malignant gastrointestinal tumours.

Adenocarcinoma is the most common histological subtype, accounting for about 40% of all malignant small intestinal tumours.

The consequences are a significant delay in diagnosis and the finding of advanced, incurable disease at operation.

The rare nature of adenocarcinomas of the small intestine has led to a paucity of information about the benefits of adjuvant chemotherapy but there are reports of overall better survival for those patients that receive combination treatment.

OBJECTIVES: To determine the role of adjuvant chemotherapy in the management of adenocarcinoma of the small intestine compared to another adjuvant treatment, a placebo or no other adjuvant treatment.

SELECTION CRITERIA: Phase III randomised controlled trials comparing post-operative adjuvant chemotherapy for adenocarcinoma of the small intestine with other adjuvant therapies, placebo or no adjuvant treatment.

AUTHORS' CONCLUSIONS: There is a need for high quality randomised controlled trials to evaluate the effectiveness of adjuvant chemotherapy in the management of adenocarcinoma of the small intestine.

[Title] [Treatment and outcome in small bowel cancer].

In adenocarcinoma of the small intestine, delays in diagnosis are frequent, and the majority of patients present with advanced- stage disease and either lymph node involvement or distant metastatic disease.

Recent retrospective and prospective studies have helped to clarify the optimal chemotherapy approach for advanced small bowel adenocarcinoma.

The 72nd Japanese Society for Cancer of the Colon and Rectum have conducted a retrospective review of Japanese patients with adenocarcinoma of the jejunum or ileum.

The data indicated that although not statistically significant, there was a trend in median overall survival favoring the chemotherapy for advanced jejunal or ileal adenocarcinoma (17 months vs. 8 months, p=0.114).

[Title] [A case report of primary adenocarcinoma of small intestine].

This is an account of a case of primary adenocarcinoma of the small intestine with peritoneal dissemination successfully treated with chemotherapy.

Abdominal computerized tomography revealed a bowel obstruction with tumor and the remarkable small bowel dilation of oral side of tumor.

Pathological diagnosis of the resected specimen was adenocarcinoma with lymph nodes metastasis.

The peritoneal dissemination consisted of metastatic adenocarcinoma from small intestine.

Primary small intestinal adenocarcinoma is a rare disease, and it is often diagnosed as advanced cancer because of few characteristic symptoms.

So carcinoma of the small intestine usually has a poor prognosis.

[Title] [A case report of primary adenocarcinoma of small intestine successfully treated with FOLFOX].

This is an account of a case of primary adenocarcinoma of the small intestine successfully treated with chemotherapy.

Abdominal computerized tomography revealed bowel obstruction, and this was found at surgery to be due to a tumor at the jejunum 100 cm distal from the Treitz ligament.

Pathological diagnosis of the resected specimen was adenocarcinoma.

Primary small intestinal adenocarcinoma is a rare disease with a dismal prognosis.

The current patient survived for 4 years and 5 months after the diagnosis, owing at least partially to the mFOLFOX6 which was found to be the only active regimen.

[Title] [Laparoscopic coincidental finding in a case of incomplete ileus: adenocarcinoma of the small intestine as first manifestation of Crohn's disease].

[Transliterated title] Laparoskopischer Zufallsbefund bei inkomplettem Ileus: Adenokarzinom des Dünndarms als Erstmanifestation eines Morbus Crohn.

The case-study reminds of adenocarcinoma of the small intestine as a rare complication of Crohn's disease.

Epidemiological studies concerning small bowel carcinoma showed consumption of sugar and carbohydrates as pathogenetic factors, other conditions like ileostoma, ileumconduit, Crohn's disease and coeliac disease have been identified to some extent.

An adenoma-carcinoma sequence as in large intestine carcinoma has been discussed.

Diagnosis of early stages of adenocarcinoma of the small intestine is very difficult and thus might be impossible to differentiate from exacerbation or progressive stenosis of preexisting Crohn's disease.

If non-invasive diagnostic measures (ultrasound, small bowel enema, CT-scan, intestinoscopy, radiography, NMR-Sellink, capsule-endoscopy) fail to clear the situation a diagnostic laparoscopy or even laparotomy should not be delayed.

[Title] Association of celiac disease and intestinal lymphomas and other cancers.

Celiac disease (CD) is associated with intestinal lymphoma and other forms of cancer, especially adenocarcinoma of the small intestine, of the pharynx, and of the esophagus.

Enteropathy-associated T-cell lymphoma (EATL) is a rare form of high-grade, T-cell non-Hodgkin lymphoma (NHL) of the upper small intestine that is specifically associated with CD.

EATL derives from a clonal proliferation of intraepithelial lymphocytes and is often disseminated at diagnosis.

RESULTS: We found most prominent EphB2 expression in the intestinal epithelium (colonic crypts) with cancer of the colorectum displaying the highest EphB2 positivity of all tumors.

EphB2 expression was also observed in 75 tumor categories, including serous carcinoma of the endometrium (34.8%), adenocarcinoma of the esophagus (33.3%), intestinal adenocarcinoma of the stomach (30.2%), and adenocarcinoma of the small intestine (70%).

The occasional finding of strong EphB2 positivity in tumors without EphB2 positivity in the corresponding normal cells [adenocarcinoma of the lung (4%) and pancreas (2.2%)] suggests that deregulation of EphB2 signaling may involve up-regulation of the protein expression.

[Title] 'Metachronous' adenocarcinoma of the small intestine.

Adenocarcinoma of the small intestine accounts for less than 1% of primary gastrointestinal malignancies (1).

Small intestine contains 75% of the length of the gastrointestinal tract with 90% of the surface mucosal area, and yet carcinoma is rare.

Symptoms of small bowel adenocarcinoma are vague and non-specific, and this region is relatively inaccessible which together contributes to their late diagnosis and poor prognosis.

The authors report a case of two primary adenocarcinomas of the small intestine in the same patient.

[Title] Small bowel adenocarcinoma.

Small bowel cancers are rare, accounting for only about 6000 cases/year in the United States, approximately 25% of which are small bowel adenocarcinomas.

Small bowel adenocarcinomas have traditionally been considered to be highly fatal due to their nonspecific presentation at the time of diagnosis, and to the lack of responsiveness to older chemotherapy regimens.

Newer diagnostic techniques such as video capsule and double balloon enteroscopy may facilitate earlier diagnosis.

Still, there remains great need for multi-institutional, cooperative group studies to define the optimal treatment of small bowel adenocarcinoma, both in the adjuvant and advanced/metastatic setting.

[Title] [Small bowel adenocarcinoma].

[Transliterated title] Adénocarcinome de l'intestin grêle.

Small bowel adenocarcinoma is a rare tumor.

Diagnosis is usually performed at an advanced stage because of non-specific nature of clinical manifestations.

New methods of radiological and endoscopic exploration of small intestine should allow earlier diagnosis.

A national prospective cohort study is currently evaluating the results of chemotherapy (recommended protocol: FOLFOX) as adjuvant and palliative treatment of small bowel adenocarcinoma.

[Title] Small intestinal adenocarcinoma in common marmosets (Callithrix jacchus).

Small intestinal adenocarcinomas are uncommon neoplasms that are rarely reported in nonhuman primates.

Herein the authors report the clinical, histologic, immunohistochemical, and molecular characteristics of small intestinal adenocarcinoma in 10 common marmosets (Callithrix jacchus).

Retrospective analysis of necropsy records revealed small intestinal carcinoma to be the most common neoplastic cause of morbidity and mortality in aged common marmosets.

Nine of 10 (90%) tumors arose within the proximal small intestine near the interface with the duodenum.

No Helicobacter-like bacteria were observed via silver stain, and callitrichine herpesvirus 3 was detected by polymerase chain reaction with equal frequency from neoplastic and nonneoplastic intestinal sections.

The tumors described in this population illustrate comparable features to human cases of small intestine carcinoma and may serve as a potential animal model for small intestinal carcinomas.

[Title] Prognostic factors of primary small bowel adenocarcinoma: univariate and multivariate analysis.

BACKGROUND: Adenocarcinoma of the small bowel is relatively less common than malignancies of the esophagus, stomach, and colorectum.

In small bowel adenocarcinoma, various prognostic factors influence the disease-free status and overall survival rates.

MATERIALS AND METHODS: Eighty patients who were diagnosed with small bowel adenocarcinoma and treated at our institute between 1983 and 2003 were retrospectively reviewed.

CONCLUSIONS: Poor prognosis of small bowel adenocarcinoma may be related to a delay in the diagnosis and treatment of the disease.

Curative resection is the aim of surgical treatment for small bowel adenocarcinoma.

[Title] Lack of HER2 overexpression and amplification in small intestinal adenocarcinoma.

HER2 overexpression and amplification have been studied as a therapeutic and prognostic target in a number of human cancers, including esophageal, gastric, and colorectal adenocarcinomas.

However, HER2 status has not been well investigated in primary small intestinal adenocarcinoma, probably because of its rarity.

In this study, we conducted immunohistochemical analysis and fluorescence in situ hybridization (FISH) for HER2 on 49 primary nonampullar small intestinal adenocarcinomas.

These observations demonstrate that HER2 protein overexpression and gene amplification are infrequent events, if they occur at all, in small intestinal adenocarcinoma.

Thus, routine immunohistochemical and/or FISH testing for HER2 for potential targeted anti-HER2 therapy may not be beneficial for patients with primary small intestinal adenocarcinoma.

[Title] Immunohistochemical investigation of tumorigenic pathways in small intestinal adenocarcinoma: a comparison with colorectal adenocarcinoma.

Small intestinal adenocarcinoma is an uncommon neoplasm morphologically similar to or indistinguishable from colorectal adenocarcinoma.

Although much has been learned about genetic pathways critical to colorectal tumorigenesis, little is known about molecular alterations involved in the development of small intestinal adenocarcinoma.

In this study, we immunohistochemically compared non-ampullary small intestinal adenocarcinomas with sporadic colorectal adenocarcinomas for the expression of several proteins known to serve pivotal roles in colorectal tumorigenesis.

The results show that complete loss of adenomatous polyposis coli immunoreactivity, presumably resulting from its gene mutations, was observed in eight of 26 (31%) small intestinal adenocarcinomas and 36 of 51 (71%) colorectal adenocarcinomas (P = 0.0008).

Nuclear localization of beta-catenin, an indirect evidence of deregulated Wnt signaling pathway, was observed in 5 (19%) small intestinal adenocarcinomas and 36 (71%) colorectal adenocarcinomas (P<0.0001).

Total lack of nuclear staining for one or more of the DNA mismatch repair enzymes occurred in a similar low frequency in both small intestinal and colorectal adenocarcinomas, seen in two of 25 (8%) and 10 of 47 (21%) cases, respectively (P = 0.1958).

The frequencies of aberrant p53 and RB expression were also similar between small intestinal and colorectal adenocarcinomas.

These observations indicate that defects in the Wnt and microsatellite instability pathways occur in over 90% of colorectal adenocarcinomas, but in only 40% of small intestinal adenocarcinomas.

Small intestinal tumorigenesis appears to follow a distinct, yet unidentified, molecular pathway(s) from its colorectal counterpart despite their morphologic similarity.

[Title] Adenocarcinoma of small intestinal type in retroperitoneal mature teratoma.

We report a case of small intestinal type adenocarcinoma arising in retroperitoneal mature cystic teratoma in a young male.

Adenocarcinoma without stromal invasion was observed adjacent to the small intestinal mucosa.

Immunohistochemistry of the adenocarcinoma tissue revealed p53 overexpression and high Ki-67 labeling index as well as positive staining for CD10, cytokeratin 7, and cytokeratin 20.

Therefore, the diagnosis of small intestinal adenocarcinoma was made.

To our knowledge, this is the first case of small intestinal adenocarcinoma arising in retroperitoneal mature cystic teratoma.

A unique feature of this case is that malignant transformation in retroperitoneal mature teratoma arose even in the fully developed intestine.

[Title] A case of small bowel adenocarcinoma in a patient with Crohn's disease detected by PET/CT and double-balloon enteroscopy.

Small bowel adenocarcinoma (SBA) in patients with Crohn's disease (CD) is quite rare, difficult to diagnose without surgery, and has a poor prognosis.

PET/CT detected an accumulation spot in the small bowel.

An endoscopic forceps biopsy specimen showed poorly differentiated adenocarcinoma.

There were some longitudinal ulcer scars near the tumor, and the chronic inflammation in the small bowel appeared to be associated with the cancer development.

Since early diagnosis is extremely difficult in these cases, novel techniques, such as PET/CT and DBE, may be expected to help in making a preoperative diagnosis of the development of SBA in CD.

[Title] Risk factors associated with small bowel adenocarcinoma in Crohn's disease: a case-control study.

BACKGROUND AND AIMS: It is well established that Crohn's disease (CD) is associated with an increased risk of small bowel adenocarcinoma (SBA).

METHODS: In 11 French centers affiliated with the GETAID (Groupe d'Etude Thérapeutique des Affections Inflammatoires du Tube Digestif), we identified 29 patients with CD and SBA.

RESULTS: In univariate analysis, the cases had had significantly less small bowel resection and received prolonged treatment with salicylates (more than 2 yr), less often than the controls (odds ratio, OR [95% confidence interval, CI] 0.07 [0.01-0.32] and 0.29 [0.10-0.82], respectively).

CONCLUSION: This study suggests that small bowel resection and prolonged salicylates use may protect against SBA in CD patients.

[Title] Adnexal mass: an unusual presentation of small-bowel adenocarcinoma.

Malignancy of the small bowel presents unique diagnostic and therapeutic challenges resulting in a delayed diagnosis in many cases.

Small-bowel tumors respond poorly to most forms of treatment.

Metastatic lesions to the ovaries comprise a small percentage of all ovarian malignant neoplasms.

Ovarian metastases from primary small-bowel tumors are often difficult to differentiate from primary ovarian tumors.

Only few reports have described ovarian metastases from small-bowel sources.

A high index of suspicion can lead to an earlier diagnosis and can have an impact on the therapeutic options as well as the survival of the patients.

[Title] Small bowel adenocarcinomas in celiac disease follow the CIM-MSI pathway.

Celiac disease (CD) is an inflammatory disorder associated with an increased risk of small bowel adenocarcinoma.

We hypothesized that CIM may link CD to small bowel carcinogenesis.

We determined microsatellite instability (MSI), CIM, and expression of MLH1 and MGMT in 3 CD-associated small bowel carcinomas and corresponding non-neoplastic mucosa.

The results were compared to those of small bowel mucosa from CD patients without carcinoma and 20 small bowel carcinomas from a non-CD origin.

In conclusion, our data reveal that the high-level CIM/MSI pathway is typical of CD-associated small bowel carcinomas and indicate that aberrant CpG island methylation links CD and carcinogenesis.

The data further suggest that CD should be considered in patients with small bowel adenocarcinoma, particularly when the tumors display MSI.

[Title] Small bowel adenocarcinoma in patients with Crohn's disease compared with small bowel adenocarcinoma de novo.

BACKGROUND: Data concerning small bowel adenocarcinoma (SBA) in Crohn's disease (CD) come from case reports and small retrospective series.

The aim of this study was to further describe SBA in patients with CD and compare it with SBA de novo.

METHODS: Twenty patients with CD with SBA recruited in French university hospitals were studied and compared with 40 patients with SBA de novo recruited from a population-based registry.

SBA occurred after a median time of 15 years of CD and was located within the inflamed areas of the ileum (n=19) or jejunum (n=1), whereas in patients with SBA de novo, it was distributed all along the small intestine.

Median age at diagnosis of SBA was 47 years (range, 33-72 yr) in patients with CD and 68 years (range, 41-95 yr) in those with SBA de novo.

Diagnosis was made preoperatively in 1/20 patients with CD and 22/40 patients with SBA de novo.

Signet ring cells were found in 35% of patients with CD but not in patients with SBA de novo.

CONCLUSIONS: SBA in CD is different from SBA de novo.

[Title] Small bowel adenocarcinoma in Crohn's disease: a case report and review of literature.

Small bowel adenocarcinomas are remarkable for their rarity, difficult diagnosis and poor prognosis.

Here we report an unusual case of a 33-year-old patient in whom infiltrative adenocarcinoma of the small bowel was diagnosed after a 10-year history of Crohn's disease.

In most previously reported cases, detection of Crohn's disease was subsequent to that of carcinoma of the small bowel or the patients involved had an even longer history of the disease.

Our literature review suggests that the risk of small bowel adenocarcinoma is higher in patients with Crohn's disease than in the overall population.

[Title] Loss of carbamoyl phosphate synthetase I in small-intestinal adenocarcinoma.

Carbamoyl phosphate synthetase I (CPS1), normally found in hepatocytes and small-intestine (SI) enterocytes, is the antigen of Hep Par 1 antibody.

Expression of CPS1 in invasive SI adenocarcinoma seems to be lost.

We retrospectively collected 36 total specimens, which included 31 SI adenomas and 21 adenocarcinomas.

Of the 21 invasive adenocarcinomas, 15 lost antigen expression (71%).

[Title] Cytoreductive surgery and intraperitoneal hyperthermic chemotherapy for peritoneal carcinomatosis from small bowel adenocarcinoma.

Small bowel adenocarcinoma is a rare etiology for PC.

METHODS: From a prospective database of IPHC patients, six patients diagnosed with PC from adenocarcinoma of the small bowel were identified.

Median survival after diagnosis of small bowel adenocarcinoma was 54 months, while median survival after CS and IPHC for PC was 30.1 months.

CONCLUSIONS: Small bowel adenocarcinoma with PC remains an unusual therapeutic challenge.

[Title] Intestinal neurofibromatosis and small-bowel adenocarcinoma: a single case study.

However, the coexistence of neurofibromatosis with small-bowel adenocarcinoma is exceedingly rare.

We present an uncommon case of neurofibromatosis type 1, involving the small bowel in a 73-year-old man, who was admitted to our department with signs of acute abdomen.

These nodules obstructed ileal lumen, while the intestine wall was perforated in one point.

Histology revealed neurofibromatosis type 1 with malignant transformation to small-bowel adenocarcinoma.

We suggest that adenocarcinoma of small bowel should be considered in the evaluation of acute abdominal pain in neurofibromatosis patients.

[Title] Adenocarcinoma of the small bowel: changes in the landscape?

PURPOSE OF REVIEW: Small bowel adenocarcinoma (SBA) is a rare cancer with a poor prognosis and little information to guide its management.

RECENT FINDINGS: Recent advances in less invasive imaging tools may permit earlier and increased diagnosis of SBA.

SUMMARY: The rarity of the disease and difficulty in diagnosis contribute to the lack of prospective trials evaluating therapies for SBA.

[Title] Small bowel adenocarcinoma in Crohn's disease.

Small bowel neoplastic disease is a rare but dreaded occurrence in Crohn's disease (CD) and the diagnosis is often disguised by nonspecific and varied presenting symptoms mimicking active or obstructive CD.

As such, the diagnosis is all too often delayed, typically detected at a late stage, and with a poor prognosis.

CD has become a well-recognized risk factor for the development of small bowel adenocarcinoma.

[Title] Expression of hepatocyte antigen in small intestinal epithelium and adenocarcinoma.

Hepatocyte antigen expression has also been detected in nonneoplastic small intestinal epithelium, but expression in small intestinal adenocarcinoma has not been well investigated.

We immunohistochemically examined 39 nonampullary small intestinal adenocarcinomas for hepatocyte antigen expression; 34 cases contained normal-appearing nonneoplastic small intestinal mucosa on the same tissue sections.

Only 9 small intestinal adenocarcinomas (23%) showed focal positive cytoplasmic staining.

In 31 colorectal adenocarcinomas, 3 (10%) showed positive staining for Hep Par 1 (1 diffuse, 2 focal), a frequency not different from that for small intestinal adenocarcinomas (P = .2467).

Hepatocyte antigen immunoreactivity is selectively expressed in nonneoplastic small intestinal enterocytes but not in colonocytes, suggesting a potential physiologic role in intestinal biology.

Whether the loss of antigen expression in a large number of small intestinal adenocarcinomas serves a role in small intestinal tumorigenesis remains to be investigated.

[Title] Natural history and chemotherapy effectiveness for advanced adenocarcinoma of the small bowel: a retrospective review of 113 cases.

BACKGROUND: Small bowel adenocarcinoma is a rare cancer that has generally been considered resistant to chemotherapy, although little has been published on the role of chemotherapy.

A retrospective analysis was conducted of patients with advanced small bowel adenocarcinoma to explore chemotherapy use, and gain knowledge for ongoing management and future clinical trials.

PATIENTS AND METHODS: All patients with advanced adenocarcinoma of the small bowel treated at Princess Margaret Hospital (PMH) between 1986 and 2004 were identified through the cancer registry.

CONCLUSION: Chemotherapy appears to have activity in adenocarcinoma of the small bowel.

[Title] High-resolution array comparative genomic hybridization in sporadic and celiac disease-related small bowel adenocarcinomas.

PURPOSE: The molecular pathogenesis of small intestinal adenocarcinomas is not well understood.

Understanding the molecular characteristics of small bowel adenocarcinoma may lead to more effective patient treatment.

EXPERIMENTAL DESIGN: Forty-eight small bowel adenocarcinomas (33 non-celiac disease related and 15 celiac disease related) were characterized for chromosomal aberrations by high-resolution array comparative hybridization, microsatellite instability, and APC promoter methylation and mutation status.

Furthermore, molecular alterations were compared between celiac disease-related and non-celiac disease-related small bowel adenocarcinomas.

RESULTS: DNA copy number changes were observed in 77% small bowel adenocarcinomas.

Celiac disease-related and non-celiac disease-related small bowel adenocarcinomas displayed similar chromosomal aberrations.

Promoter hypermethylation of the APC gene was found in 48% non-celiac disease-related and 73% celiac disease-related small bowel adenocarcinomas.

Thirty-three percent of non-celiac disease-related small bowel adenocarcinomas showed microsatellite instability, whereas 67% of celiac disease-related small bowel adenocarcinomas were microsatellite unstable.

CONCLUSIONS: Our study characterized chromosomal aberrations and amplifications involved in small bowel adenocarcinoma.

At the chromosomal level, celiac disease-related and non-celiac disease-related small bowel adenocarcinomas did not differ.

A defect in the mismatch repair pathways seems to be more common in celiac disease-related than in non-celiac disease-related small bowel adenocarcinomas.

In contrast to colon and gastric cancers, no APC nonsense mutations were found in small bowel adenocarcinoma.

However, APC promoter methylation seems to be a common event in celiac disease-related small bowel adenocarcinoma.

[Title] Retained capsule endoscope leading to the identification of small bowel adenocarcinoma in a patient with undiagnosed Crohn disease.

Small intestinal neoplasia is a rare condition that frequently presents a diagnostic challenge.

We describe the case of a 70-year-old patient who presented with several years of chronic, intermittent abdominal pain, previously diagnosed as irritable bowel syndrome.

Radiographic evaluation, including upper gastrointestinal series with small bowel follow-through and computed tomography, demonstrated dilated small bowel with possible strictures.

Extensive flat and polypoid high- and low-grade dysplasia were present, as well as an area of well-differentiated adenocarcinoma invading into the muscularis propria.

We discuss the epidemiology, pathogenesis, and diagnosis of small bowel malignancy.

[Title] Resection of small bowel adenocarcinoma liver metastasis combined with neoadjuvant and adjuvant chemotherapy results in extended disease-free period--a case report.

Small bowel adenocarcinoma (SBA) is a very rare tumor entity but occurs in up to 5% of patients suffering from familiar adenomatous polyposis (FAP).

Because of nonspecific symptoms, diagnosis is usually made with delay, which contributes to high rates of metastatic disease at the time of diagnosis.

In October 2001, a 51-year-old woman with attenuated FAP, that had total proctocolectomy in 1994 was diagnosed with a jejunal adenocarcinoma.

She subsequently underwent small bowel resection.

Afterwards, a small residual lesion in segment VIII was seen in CT scan but could not be identified by PET and at laparotomy in November 2002.

[Title] [Primary small bowel adenocarcinoma].

[Transliterated title] Adenocarcinoma primario de intestino delgado.

INTRODUCTION: Primary small bowel adenocarcinoma is an uncommon tumour, with non-specific symptoms that cause a delay in the diagnosis and consequently a worse outcome for the patient.

MATERIAL AND METHOD: We performed a retrospective study of our experience with 17 patients diagnosed with primary small bowel adenocarcinoma, excluding all the cases suggesting secondary involvement of the small bowel from an adenocarcinoma in other locations.

Those with duodenal tumours underwent 4 pancreaticoduodenectomies, 3 gastroenterostomies and 1 diagnostic biopsy; 6 bowel resections with lymphadenectomy, 2 en-bloc resections and 1 by-pass were performed on those with jejuno-ileal tumours.

CONCLUSIONS: Curative treatment consists of small bowel resection.

[Title] [A case of primary jejunal adenocarcinoma diagnosed by enteroscopy using pediatric colonoscope].

Endoscopic jejunal biopsy showed moderately differentiated adenocarcinoma.

Small intestinal adenocarcinoma is uncommonly encountered in clinical practice.

Because small intestine is relatively inaccessible via routine endoscopy, diagnosis of small intestinal neoplasm is often delayed for several months after the onset of symptoms.

Therefore, when a small bowel neoplasm is suspected, enteroscopy is the most useful study.

If enteroscope is not available, enteroscopy using pediatric colonoscope may permit earlier preoperative diagnosis.

We report a case of primary jejunal adenocarcinoma diagnosed by endoscopic biopsy using pediatric colonoscope.
