[From molecular biology to new treatment approaches to colorectal cancer: basic research, experimental trials and surgical implications]

Abstract

The Authors review the natural history of colorectal cancer from the point of view of molecular biology and genetics from aberrant crypts foci and familiar adenomatous polyposis to hereditary non polyposis colon cancer and sporadic colorectal cancer. They carry out international literature about basis knowledges, experimental trials and personal studies. Up to day traditional colorectal cancer surgical treatments and adjuvant or neoadjuvant pharmacological therapy cannot be modified, nevertheless "new drugs generation" known as signal transduction inhibitor could, in the future, prove to be an effective cancer treatment. The Authors highlight recent experimental clinical trials probably able to prevent sporadic colorectal cancer spreading and precursor evolution.
