Research Summary

Dr. Alan Venook is the Madden Family Distinguished Professor of Medical Oncology and Translational Research at UCSF and is the Shorenstein Associate Director for Program Development at the Helen Diller Family Comprehensive Cancer Center at UCSF. He was the founding Chairman of the NCI’s Hepatobiliary Task Force, chaired the GI Committee of the Alliance for Clinical Trials in Oncology from 2010 -2016 and was an Associate Editor of the Journal of Clinical Oncology from 2010 - 2015.

Dr. Venook’s research interests include the regional treatment of tumors in the liver and the development of new therapies for colorectal and liver cancers. It was his observation from data in the advanced colorectal cancer study -- CALGB/SWOG 80405 – that helped define “sidedness”, the phenomenon that colon cancers arising in the right colon are biologically different than those that arise on the left side. Recently his group has turned its focus to understanding the interactions between immunotherapy and the microbiome and the marked increase in colorectal cancer in young adults.
