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

Abstract

We show evidence that CRC tumors arising in HNPCC families without MMR alterations have distinctive molecular features. Overall, our work shows that systematic analysis of somatic alterations in a well-defined subset of CRCs is a good approach to provide new insights into the mechanisms of colorectal carcinogenesis.
