Colorectal cancer is currently the third most common cancer in Malaysia. Elevated expression of COX-2, an induced cyclooxygenase isoenzyme, has been seen in colonic adenomas and colorectal carcinoma. There is evidence that inhibition of this COX-2 can decrease the risk of colorectal cancer. Selective COX-2 inhibitors may have a role in reducing the risk of colorectal cancer in high-risk individ...

3563 Background: Molecular tumor profile assays (MTP) may predict the primary site of origin in CUP, but the impact of site-specific therapy on outcomes is undefined. Accurate identification of CUP patients (pts) with a colorectal site of origin would be expected to improve treatment results by directing the use of colorectal cancer regimens rather than empiric CUP regimens. METHODS We identi...

Background: Colorectal endoscopy is the gold standard investigation of the large bowel in patients with rectal bleeding and is employed as a means of secondary prevention of colorectal cancer. Aim: To determine the frequency of benign lesions and carcinomas in patients who underwent colorectal endoscopy because of rectal bleeding and to evaluate the role of endoscopy in secondary prevention of ...

Dendritic cell (DC)-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) is a type II transmembrane C-type lectin expressed on DCs such as myeloid DCs and monocyte-derived DCs (MoDCs). Recently, we have reported that DC-SIGN interacts with carcinoembryonic antigen (CEA) expressed on colorectal carcinoma cells. CEA is one of the most widely used tumor markers for gastrointe...

Background: The genetic background in breast cancer families with colorectal and/or endometrial cancer is mostly unknown. The functional connection between MSH6 and the known breast cancer predisposition gene product BRCA1 suggests that the MSH6 gene may also play a role in breast cancer predisposition. Methods: We analysed 38 breast cancer families with colorectal and/or endometrial cancer for...

In the present study, we investigated the prognostic and diagnostic significance of -catenin nuclear immunostaining in 60 specimens of normal colorectal tissue; 180 specimens of colorectal polyps, adenomas, and carcinomas; and 40 specimens from patients with the simultaneous occurrence of polyps, adenomas, and carcinomas. Additional specimens from 59 patients with colorectal carcinoma and 14 pa...

High mobility group I(Y) [HMGI(Y)] proteins are architectural factors abundantly expressed during embryogenesis, and their overexpression is known to be closely associated with neoplastic transformation of cells. This study was performed to investigate whether determination of HMGI(Y) expression level could assist in (a) differential diagnosis between colorectal carcinoma, adenoma, and normal t...

The aim of this study was to investigate the clinicopathological characteristics of colorectal serrated lesions associated with invasive carcinoma and high-grade intraepithelial neoplasm (HIN), as well as to determine the immunohistochemical expression of MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), K-ras and O6-methylguanine-DNA methyltransferase (MGMT). A total of 5,347 cases diagnosed with ...
