Molecular origins of cancer: Molecular basis of colorectal cancer.

Abstract

This review gives an account of recent advances in our knowledge of the molecular mechanisms in colorectal cancer. Genetic changes in the germ line, combined with somatic mutations, occur in familial syndromes of colorectal cancer, whereas somatic mutations are the outstanding feature of sporadic colorectal cancer. Genetic changes drive the progression from adenoma to carcinoma and probably influence individual susceptibility and response to treatment.
