Sporadic Colorectal Cancers With Microsatellite Instability and Their Possible Origin in Hyperplastic Polyps and Serrated Adenomas
5 Sept 2001
Abstract excerpt
BACKGROUND: Microsatellite instability (MSI) is seen in 10%-15% of sporadic colorectal cancers mostly in the right colon, but the precursors of cancers with MSI remain unknown. We examined whether sporadic cancers with MSI arise from pre-existing benign proliferative lesions (such as hyperplastic polyps or serrated adenomas [together denoted as "serrated polyps"]). METHODS: The frequency of benign epithelial...
