Molecular Analysis of Colorectal Cancer Tumors from Patients with Mismatch Repair–Proficient Hereditary Nonpolyposis Colorectal Cancer Suggests Novel Carcinogenic Pathways

Abstract excerpt

PURPOSE: A subset of colorectal cancers (CRC) arises in families that, despite fulfilling clinical criteria for hereditary nonpolyposis colorectal cancer (HNPCC), do not show evidence of a mismatch repair (MMR) deficiency. The main objective of this study was to characterize these tumors at the molecular level. EXPERIMENTAL DESIGN: After comprehensive germ line mutation scanning, microsatellite analysis, and MMR...
