A67 -year-old man was diagnosed with ascending colon cancer and multiple liver metastases and underwent laparoscopic right hemicolectomy(D3 lymphadenectomy). Pathological examination indicated tubular adenocarcinoma(tub1, pT4apN2H2M1[HEP], pStage Ⅳ). After chemotherapy, he underwent hepatectomy. One year and 9 months after the first operation, obstructive jaundice appeared. Abdominal computed tomography revealed a tumor 2 cm in size in the head of the pancreas. After several detailed examinations, he was diagnosed with pancreatic metastasis of ascending colon cancer...

BACKGROUND: Anatomic location of primary tumors across the colon correlate with survival in the metastatic setting, whereas left-sided tumors may exhibit superior survival compared with right-sided tumors. The Oncotype Recurrence Score (RS) assay is a clinically validated predictor of recurrence risk in patients with stage II colorectal cancer (CRC). Previous studies had indicated that without adjuvant chemotherapy, CDX2-negative stage II CRC tumors are associated with a lower rate of disease-free survival than CDX2-positive stage II CRC tumors...

Chronic exposure to inorganic arsenic (As)-As(III) + As(V)-is associated with type 2 diabetes, vascular diseases and various types of cancer. Although the oral route is the main way of exposure to inorganic As, the adverse gastrointestinal effects produced by chronic exposure are not well documented. The aim of the present study is to evaluate the effect of chronic exposure to As(III) on the intestinal epithelium. For this purpose, NCM460 cells, non-transformed epithelial cells from the human colon, were exposed to As(III) (0...

Caudal-related homeobox transcription factor 2 (CDX2), an intestine-specific nuclear transcription factor, has been strongly implicated in the tumourigenesis of various human cancers. However, the functional role of CDX2 in the development and progression of colorectal cancer (CRC) is not well known. In this study, CDX2 knockdown in colon cancer cells promoted cell proliferation in vitro, accelerated tumor formation in vivo, and induced a cell cycle transition from G0/G1 to S phase, whereas CDX2 overexpression inhibited cell proliferation...

Hepatoid adenocarcinoma (HAC) is rare and was first reported as α-fetoprotein (AFP)-producing tumor. It is an important variant of extrahepatic adenocarcinoma with clinicopathological presentation mimicking hepatocellular carcinoma and carries exceedingly poor prognosis. HAC most commonly originates in the stomach, and less commonly in the ovary, esophagus, lung, among other organs. HAC originating in the colon is exceedingly rare. Here we report such a case of a 63-year-old man presented as decompensated liver failure with jaundice and weakness...

Colorectal cancer (CRC) is the third most common cancer and the third leading cause of cancer death in the United States. Growth Factor Independent 1 (GFI1) is a zinc finger transcriptional repressor responsible for controlling secretory cell differentiation in the small intestine and colon. GFI1 plays a significant role in the development of human malignancies, including leukemia, lung cancer and prostate cancer. However, the role of GFI1 in CRC progression is largely unknown. Our results demonstrate that RNA and protein expression of GFI1 are reduced in advanced stage non-mucinous CRC...

BACKGROUND & AIMS: Neutrophils are among the most prevalent immune cells in the microenvironment of colon tumors, are believed to promote growth of colon tumors, and their numbers correlate with outcomes of patients with colon cancer. Trials of inhibitors of neutrophil trafficking are under way in patients with cancer, but it is not clear how neutrophils contribute to colon tumorigenesis. METHODS: Colitis-associated colon cancer was induced mice with conditional deletion of neutrophils (LysMCre;Mcl1fl/fl ) and wild-type littermates (LysMCre;Mcl1+/+ , control mice) by administration of azoxythmethane and/or dextran sulfate sodium...

BACKGROUND: Most colorectal cancer liver metastases form nodules within the hepatic parenchyma, and hepatectomy is the only radical treatment for synchronous metastases. There is concern about intrabiliary tumor growth which may affect the surgical margin, resulting in local recurrence after hepatectomy for colorectal cancer liver metastasis; however, there has been no report of the dissemination in the bile duct after hepatectomy. Here, we report an unusual case of biliary dissemination of colorectal cancer that caused recurrent intrabiliary growth after hepatectomy, and discuss the management of intrabiliary metastasis of colorectal cancer...

A 43-year-old man presented with two-month history of fatigue, weakness, paleness, rectal bleeding, sweating, and weight loss of 10 kg in the past one month. A complete blood count revealed anaemia. The patient underwent a right hemicolectomy. The microscopic examination revealed an adenosquamous carcinoma associated with a mucinous adenocarcinoma in a patient with microsatellite instability due to loss of MLH1 and PMS2 expression and retention of MSH2 and MSH6 expression in both the squamous and glandular components...

Colorectal cancers (CRCs) harbor accumulated defects in key signaling pathways that regulate cell phenotypes, including proliferation, survival, metabolism, and differentiation. To study the functional contributions of the accumulated molecular defects in CRC, we have developed approaches to inactivate selected tumor suppressor and/or activate oncogenes in mouse colon epithelium. Conditional inactivation of the CDX2 tumor suppressor protein in conjunction with oncogenic activation of the BRAF protein promotes development of serrated glandular benign and malignant tumors in the mouse colon...

Although pancreatic and gastric heterotopias are common findings in the gastrointestinal tract, heterotopic respiratory mucosa (HRM) in the rectum is extremely rare and has only been reported twice previously. We are presenting, to our knowledge, the third case of HRM in the rectum. A 56-year-old man with a history of chronic diarrhea presented for diagnostic colonoscopy, where he was found to have a rectal subepithelial nodule. He was subsequently referred to a tertiary medical center for further evaluation with rectal endoscopic ultrasound...

Colonic metastasis from lung cancer is rare, generally asymptomatic and usually develop at advanced cancer stages. Here, we report a case with a resected stage IA lung adenocarcinoma in a 51yo male patient that presented two years later with mild abdominal pain due to intestinal obstruction caused by a metastatic colon tumor. The patient underwent colonoscopy followed by surgical resection and the pathologic report was adenocarcinoma which was the same as that from a lung nodule that was excised two years earlier...

Lynch syndrome (LS) patients with isolated PMS2 loss in the colon cancer, while intact MMR in the prostate cancer, are exceedingly rare. Herein, we report such a case. A 71-year-old male was found to have increased serum PSA (10 ng/ml) after treatment for his urinary tract infection. Prostate biopsies showed foci of prostate cancer with Gleason score 7 (3+4) (grade grope 2) involving 10% of two cores. Through work up for treatment of the prostate cancer, he was found to have focal thickening of his sigmoid colon with adjacent lymphadenopathy in CT scans...

Sequencing of primary colorectal tumors has identified a gene fusion in approximately 3% of colorectal cancer patients of the VTI1A and TCF7L2 genes, encoding a VTI1A-TCF4 fusion protein containing a truncated TCF4. As dysregulation of the Wnt signaling pathway is associated with colorectal cancer development and progression, the functional properties and transcriptional regulation of the VTI1A-TCF4 fusion protein may also play a role in these processes. Functional characteristics of the VTI1A-TCF4 fusion protein in Wnt signaling were analyzed in NCI-H508 and LS174T colon cancer cell lines...

Intestinal-type adenocarcinoma of the primary salivary glands is extremely rare. So far, only 11 cases of primary intestinal-type adenocarcinoma of the oral cavity and major salivary glands have been reported. Two of those tumors arose in the floor of mouth, 7 in the tongue, and 2 in the major salivary glands. However, it has remained unclear whether these tumors are derived from mature salivary glands, and primary intestinal-type adenocarcinoma of the buccal mucosa has not been reported previously. Here, we present the first documented case of primary intestinal-type adenocarcinoma arising in a minor salivary gland of the buccal mucosa...

CDX2 is routinely used for identifying gastrointestinal origin of metastatic adenocarcinomas; but a high percentage of other carcinomas also show positivity with this antibody. SATB2 is a new immunohistochemical marker with a few studies showing that it is specifically expressed in a large majority of colorectal adenocarcinomas. We assessed SATB2 along with CDX2 in patient material with metastasis in order to determine whether the primary site could be identified as 'colon-rectum'. Metastasis in 67 liver biopsies, 108 lymph nodes from resection specimens and 36 serous effusions was analyzed retrospectively...

Colorectal cancer (CRC) is the second most frequent and fatal cancer in Western countries. Understanding its biology with different incidence along the colon and rectum, genetic profile and how these factors contribute to local/distant progression, has been hampered by the lack of a suitable CRC model. We report a reproducible model, using human CRC cell lines (CL) (WiDr, LS1034, C2BBe1) injected (1 × 107 cells/animal) in RNU rats (n = 55) which underwent cecostomy and descending colostomy with mucosal-cutaneous fistula of the sigmoid colon...
