Hereditary nonpolyposis colorectal cancer (HNPCC)/Lynch syndrome.

Hereditary Nonpolyposis Colorectal Cancer (HNPCC)/Lynch Syndrome: Surveillance and Diagnostic strategies

Introduction: Hereditary nonpolyposis colorectal cancer (HNPCC, Lynch syndrome) is an autosomal dominant genetic disease. The disease is caused by a mutation in one of four genes of the DNA mismatch repair system and increases the risk for various cancers, especially the uterine and colon cancers. The prevalence of this disease in the general population is about 1 in 500 and it causes about 2-3...

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

The Lynch Syndrome: Melding Natural History and Molecular Genetics to Genetic Counseling and Cancer Control.

Hereditary nonpolyposis colorectal cancer (HNPCC), also referred to as Lynch syndromes I and II, is an autosomal, dominantly inherited disorder that accounts for approximately 5% of all colorectal cancers. While colorectal cancer is the most frequently occurring malignancy in HNPCC, other types of cancer occur with increased statistical significance. A better understanding of its natural histor...

Tobacco use and increased colorectal cancer risk in patients with hereditary nonpolyposis colorectal cancer (Lynch syndrome).

BACKGROUND The marked variability in age at onset of colorectal cancer (CRC) in patients with hereditary nonpolyposis colorectal cancer (HNPCC) makes management decisions difficult. Environmental factors governing the phenotypic variability of cancer-associated syndromes such as HNPCC have not been elucidated. METHODS We determined whether tobacco use would alter CRC risk in carriers of HNPCC...

سندرم Lynch -l و گزارش شش مورد بیمار مبتلا

More than two decades ago, Henry T. Lynch reported a hereditary non polyposis colorectal cancer (HNPCC) which is seen in some families with dominant mode of inheritance, also know as Lynch Syndrome type I and II. This form to hereditary colorectal cancer has an early age of onset (Less than 45 years) with predominantly proximal colonic involvement (type I) and can also be associated with extrac...

Revised Bethesda Guidelines for hereditary nonpolyposis colorectal cancer (Lynch syndrome) and microsatellite instability.

Hereditary nonpolyposis colorectal cancer (HNPCC), also known as Lynch syndrome, is a common autosomal dominant syndrome characterized by early age at onset, neoplastic lesions, and microsatellite instability (MSI). Because cancers with MSI account for approximately 15% of all colorectal cancers and because of the need for a better understanding of the clinical and histologic manifestations of ...
