OBJECTIVE There are few studies which characterised the molecular alterations in premalignant colorectal adenomas. Our major goal was to establish colorectal adenoma genome atlas and identify molecular markers of progression from colorectal adenoma to adenocarcinoma. DESIGN Whole-exome sequencing and targeted sequencing were carried out in 149 adenoma samples and paired blood from patients wi...

Colorectal epithelial neoplasia (CR-EN), both adenoma and adenocarcinoma, may develop from the essential tubules of the colorectum. In order to conclude the carcinogenesis of the colorectal cancer more clearly, the biological features including the genetic abnormality of the nonneoplastic mucosal epithelium of colon and rectum, which coexist in connection with CR-EN, should be investigated. In ...

OBJECTİVE: In this study, it was aimed to evaluate the antineoplastic efficacy of Teranecron, which is frequently used in veterinary medicine, on human colorectal adenocarcinoma.
 MATERİALS AND METHODS: Teranecron (TRN) its effectiveness and drug Doxorubicin as a positive control. The cytotoxic activity cell line CaCo-2 investigated. MTT proliferation test determine viability rates. ANOVA ...

Colorectal adenomas are well known precursors of invasive adenocarcinoma. Colonoscopy is the gold standard for adenoma detection. Colonoscopy is far more than a diagnostic tool, as it allows effective treatment of colorectal adenomas. Endoscopic resection of colorectal adenomas has been shown to reduce the incidence and mortality of colorectal cancer. Difficult resection techniques are availabl...

Even though the small intestine contains 90% of the gastrointestinal tract mucosa and is located between the stomach and large intestine, two organs with a high cancer incidence, adenocarcinoma of the small intestine is 1/50th as common as adenocarcinoma of the large bowel. In several other respects, small-intestinal adenocarcinoma resembles large bowel adenocarcinoma; eg, it arises from adenom...

CONTEXT The relevance of colorectal adenocarcinoma lies in its high incidence, with the liver being the organ most frequently affected by distant metastases. Liver metastases occur in 40 to 50% of patients with colorectal adenocarcinoma, accounting for approximately 80% of deaths in the first three postoperative years. Nevertheless, despite this, they are occasionally susceptible to curative tr...

AIM To evaluate the impact of recombinant Bacteroides fragilis enterotoxin-2 (BFT-2, or Fragilysin) on colorectal tumorigenesis in mice induced by azoxymethane/dextran sulfate sodium (AOM/DSS). METHODS Recombinant proBFT-2 was expressed in Escherichia coli strain Rosetta (DE3) and BFT-2 was obtained and tested for its biological activity via colorectal adenocarcinoma cell strains SW-480. Seve...

Adenocarcinomas of the colon and rectum are graded using a 2-tiered system into histologic low-grade and high-grade tumors based on the proportion of gland formation. The current grading system does not apply to subtypes of carcinomas associated with a high frequency of microsatellite instability (MSI), such as mucinous and medullary carcinomas. We investigated the combined effect of histologic...

Parameters of histological type, differentiation, lymph node metastasis and stage have been observed to indicate the prognosis of colorectal carcinomas. Immunohistochemically E-cadherin and β -catenin expression of tumour cells have been evaluated to define life expectancy, response to the treatment, metastatic disease and recurrence of tumour in correlation with these prognostic parameters. 60...
