A Case of the Hereditary Nonpolyposis Colorectal Cancer with Maicrosatellite Instability.

Hereditary nonpolyposis colorectal cancer.

Hereditary nonpolyposis colorectal cancer (HNPCC), or Lynch syndrome, is the most common form of hereditary colorectal cancer (CRC). A well-orchestrated cancer family history is essential for its diagnosis since, unlike its familial adenomatous polyposis (FAP) hereditary cancer counterpart, HNPCC lacks distinguishing clinical stigmata of its cancer genetic risk. Discoveries in the 1990s of germ...

Genetics of hereditary nonpolyposis colorectal cancer.

Colorectal cancer is a major cause of morbidity and mortality. About 15 - 20% of all colorectal cancers are familial. Hereditary nonpolyposis colorectal cancer is an inherited cancer predisposition syndrome. It is caused by mutations in mismatch repair genes, predominantly MSH2 and MLH1. Although hereditary nonpolyposis colorectal cancer accounts for a minority of colorectal cancers, the mutati...

Evaluation of MLH1 and MSH2 Gene Mutations in a Subset of Iranian Families with Hereditary Nonpolyposis Colorectal Cancer (HNPCC)

hereditary nonpolyposis colorectal cancer in northeastern iran

background: there are no data on familial aggregation of colorectal cancer (crc) in northeastern iran. the aim of this study was to determine the prevalence of early-onset crc and patients suspected for hereditary non-polyposis colorectal cancer (hnpcc) based on the clinical criteria in this area. materials and methods: documents were collected from two hospitals in mashhad regarding 326 inpati...

Gynecologic Manifestations of Hereditary Nonpolyposis Colorectal Cancer

Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant cancer susceptibility syndrome associated with inherited defects in the DNA mismatch repair system. HNPCC family members are at high risk for developing colorectal, endometrial, and ovarian cancers. Studies of HNPCC families have helped define the important role that mismatch repair genes play in the molecular pathogenes...
