Chronic inflammatory diseases pre-dispose to carcinoma
Patients with unremitting inflammatory bowel disease (IBD) are at increased risk of developing intestinal carcinoma, including colorectal cancer. My cancer research focus is on understanding the processes that contribute to this risk in IBD. For example, we recently discovered that tumor necrosis factor, a target in the prevention of inflammation, also directly contributes to cancer development. I am also working to reduce the mucosal damage that cancer therapeutics cause, in order to improve patient responses.
