Lynch Syndrome (HNPCC) and Microsatellite Instability
A departure from the concept of simple adenoma to carcinoma sequence is the realization that colorectal cancer (CRC) develops through at least two major molecular pathogenic pathways, namely chromosomal instability (CIN) and microsatellite instability (MSI) [1,2]. The mechanisms underlying CIN might have been the first to be deciphered but they are just being understood in detail. It is propose...
متن کامل[Lynch syndrome: selection of families by microsatellite instability and immunohistochemistry].
BACKGROUND Selection of patients with Lynch Syndrome (LS) for a genetic study involves the application of clinical criteria. To increase the rate of identification of mutations, the use of molecular studies as Microsatellite Instability (MSI) and Immunohistochemistry (IHC) in the tumor has been proposed. AIM To demonstrate the usefulness of MSI and IHC in the detection of mutations in patient...
متن کاملLynch syndrome (HNPCC) and microsatellite instability analysis guidelines.
The “International Workshop on Diagnostic Guidelines for Hereditary Non-Polyposis Colorectal Cancer and Microsatellite Instability” represents the third workshop in this series. In November 1996, NCI’s DCP convened a workshop entitled “Intersection of Pathology and Genetics in HNPCC Syndrome.” In December 1997, another workshop, “International Workshop on Microsatellite Instability and Replicat...
متن کاملtumor microsatellite instability and clinicopathologic features in iranian colorectal cancer patients at risk for lynch syndrome
background: microsatellite instability (msi) is a mutational signature that is the hallmark of lynch syndrome, and msi testing is a cost-effective method to screen the disease. since there is no enough data about msi status and associated clinicopathologic features of hereditary nonpolyposis colorectal cancer (hnpcc) in iran, our study is a new trial to describe them in center of iran (isfahan)...
متن کاملRevised 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 ...
