BACKGROUND Loss of E-cadherin expression has been implicated in the development of invasive characteristics in colorectal carcinomas. Failure to express E-cadherin may result from mutations of the E-cadherin gene (HSECAD). AIMS To examine the correlation between E-cadherin expression and genetic changes at HSECAD; and to examine differences in E-cadherin expression and genetic changes at HSEC...

COLORECTAL CANCER IS CLASSIFIED IN TO THREE FORMS sporadic (70-75%), familial (20-25%) and hereditary (5-10%). hereditary colorectal cancer syndromes classified into two different subtypes: polyposis and non polyposis. Familial Adenomatous polyposis (FAP; OMIM #175100) is the most common polyposis syndrome, account for <1% of colorectal cancer incidence and characterized by germline mutations i...

background: vascular endothelial growth factor (vegf) is a signal protein produced by cells that stimulates angiogenesis and increased vascular permeability. the prognostic value of vegf expression in colorectal cancer is unclear as shown by the discordant results still reported in the literature. this study was designed for the evaluation of vegf expression and correlation with clinicopatholog...

background colorectal cancer (crc) is the second most common malignancy in the world.  however, its mortality rate can be reduced if diagnosed early. p33 ing1b is a tumor suppressor protein, which plays a role in growth control and apoptosis. suppression of p33 ing1b is associated with the loss of cellular growth control. however, p33 ing1b expression in crc and its correlations with clinicopat...

background: improvement in complications of antitumor agents and surgery is important to enhance life quality and survival among patients with colon and colorectal cancer. it has been reported that some dietary components such as glutamine (gln) have beneficial effects on these complications of cancer therapies. however, the results of studies are inconsistent in this area. we performed a revie...

Metastatic ovarian cancers occur in 3-8 percent of women undergoing surgical resection of a primary colorectal cancer. In this study we examined the characteristics of women with colorectal cancer for whom synchronous oophorectomy had been performed. In this cross-sectional study, records of patients with colorectal cancer from April 1991 through October 1999 who had undergone surgery for ...
