Hereditary nonpolyposis colorectal carcinoma (HNPCC) is the most common hereditary form of colorectal carcinoma (CRC) and may account for 5-10% of the total CRC burden. The discovery of DNA mismatch repair (MMR) genes, inclusive of hMSH2, hMLH1, hPMS2, and hMSH6, has enabled the identification of wh

Lynch syndrome, or hereditary nonpolyposis colon cancer (HNPCC), is an autosomaldominant disease accounting for approximately 1 5 % of all colorectal cancer cases. Due to the lack of pathognomonic morphological or biomolecular markers, HNPCC has traditionally posed unique problems to clinicians and
## BACKGROUND. Patients with hereditary nonpolyposis colorectal carcinoma (HNPCC) reportedly have better prognoses than sporadic colorectal carcinoma (CRC) patients, but it has been unclear whether this could be due to differences in stage at diagnosis. The current study compared stage and surviva
## BACKGROUND. Small bowel carcinoma is uncommon. However, hereditary nonpolyposis colorectal carcinoma (HNPCC) patients are at increased risk of small bowel carcinoma. The purpose of this study was to characterize small bowel tumors in HNPCC patients. ## METHODS. A questionnaire was mailed to
Hereditary nonpolyposis colorectal cancer (Lynch syndrome) is an autosomal dominant disease caused by mutations in the mismatch repair genes in particular in MLH1, MSH2 and MSH6. The disease is characterized by the development of colorectal, endometrial cancer and several other cancers. There is evi
## Background: It has been estimated that the prevalence of carriers of a mutated mismatch repair (mmr) gene among the general population in western countries is between 5 and 50 per 10,000. these carriers have a risk of >85% of developing colorectal carcinoma (crc) and therefore need careful follo
