✦ Synopsis

Ras gene mutations occur relatively early during colorectal tumor development and have been observed in 40-509'0 of malignant colorectal tumors. Advances in endoscopic techniques have made it possible to detect small, flat colorectal tumors that could not be detected by standard examinations. To determine whether ras gene mutations are also involved in the genesis of small, flat colorectal tumors, we examined ras

Activating mutations in the Ki-ras2 oncogene are frequently observed in sporadic colorectal adenomas and their incidence is reported to rise in large and tubulovillous adenomas to values close to those in carcinomas. This study shows that this property is a feature of adenomas growing in large bowel
