As Newfoundland has the highest rate of familial colorectal cancer (CRC) in the world, we started a population-based clinic to provide colonoscopic and Lynch syndrome (LS) screening recommendations to families of CRC patients based on family risk. Of 1091 incident patients 51% provided a family history. Seventy-two percent of families were at low or intermediate-low risk of CRC and colonoscopic...

Cutaneous neoplasms including sebaceous tumors, keratoacanthomas, and basal cell carcinomas with sebaceous differentiation can be markers of internal malignancy associated with the Muir-Torre Syndrome (MTS). We report a 56-year-old man with a diagnosis of hereditary nonpolyposis colorectal cancer (HNPCC) and ureteral transitional cell carcinoma who subsequently developed two sebaceous gland neo...

A common polymorphism in the cyclin D1 gene enhances the gene’s alternate splicing. The alternatively spliced product encodes an altered protein that does not contain sequences involved in the turnover of the protein. We found that hereditary nonpolyposis colorectal carcinoma patients who were homozygous or heterozygous for the mutant allele developed colorectal cancer an average of 11 years ea...

PURPOSE The causative genes for autosomal dominantly inherited familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer have been well characterized. There is, however, another 10% to 15% of early onset colorectal cancers (CRC) in which the genetic components are unclear. In this study, we used microarray technology to systematically search for differentially expressed...

Several predispositions to colorectal cancer have been identified, but little is known about genetic susceptibilities to disease in older persons. Colorectal cancer is a risk in Crohn's disease and is believed to be associated with an inappropriate inflammatory response. Recently, the NOD2 gene has been associated with Crohn's disease, which further strengthens the notion that the inflammatory ...

BACKGROUND Colorectal cancer is a major cause of cancer mortality and morbidity. Screening can potentially prevent most colorectal cancers by detection and removal of precursor adenomas. METHODS The literature and clinical practice guidelines are reviewed, with an emphasis on advances of the last 10 years and evolving screening methods. RESULTS Colonoscopy has come to be used for screening ...
