Dr. Ahnen’s research interess include the biologic and the biochemical mechanisms of the chemopreventive effects of the non-steroidal anti-inflammatory drugs (NSAIDs). He is currently examining the effect of NSAIDs on EGF receptor expression and function. His clinical trials group participates in several colorectal cancer prevention trials including several adenoma chemoprevention trials.
