Abstract
The frequency and spectrum of mutations in RAS/BRAF genes were studied in rectal adenomas, carcinomas in situ, and adenocarcinomas. It is shown that the frequency of KRAS mutations decreases from adenoma to adenocarcinoma; most adenomas and carcinomas in situ are heterogeneous and consist of several subclones. Possible models of colorectal cancer pathogenesis are discussed.
