Developing non-invasive colon cancer screening tests
Dr. Itzkowitz's team was part of a national study that demonstrated the utility of stool DNA testing for detecting colon cancer and precancerous polyps in the general population. He is now leading a national study that is testing a modified version of the stool DNA test in patients with IBD who are at increased risk for developing colorectal cancer.

Cancer Risk in Patients with Inflammatory Bowel Disease
Many patients with inflammatory bowel disease (IBD) take medicines that affect their immune system. Most of these drugs were initially tested in patients with IBD who did not have a past history of cancer for fear that these agents might promote a recurrence or development of a new cancer. But a recent study by Dr. Itzkowitz and coworkers indicates that even in those patients with IBD who have a history of cancer, taking immune modulating medicines did not predispose them to a recurrence of their cancer or the development of a new cancer. Dr. Itzkowitz is now heading a multicenter registry to follow patients with IBD who have a history of cancer to track their rates of new or recurrent cancer in a prospective fashion.
Reducing disparities in screening colonoscopy
Dr. Itzkowitz helped spearhead community outreach efforts to enhance awareness of colon cancer in East Harlem. He and his colleagues have demonstrated the effectiveness of new strategies to improve the completion rates of screening colonoscopy among minority individuals by employing patient navigators within an open access referral system. This model has now been accepted by most medical centers and ambulatory clinics. 
Mechanisms of inflammation-associated carcinogenesis
Laboratory investigation is exploring the profile of intestinal microbiota in patients with inflammatory bowel disease (IBD) who have primary sclerosing cholangitis - conditions that predispose to colon cancer.



 
Progression of Neoplasia in Inflammatory Bowel Disease
Studies at Mount Sinai are examining clinical and pathological risk factors to help better understand the factors that promote progression from inflammation to precancerous and cancerous lesions in the colon in patients with IBD. Dr. Itzkowitz is the PI on a new registry that will follow patients with IBD and a past history of cancer who are treated with immune modulating medicines for their IBD, in order to determine whether these medications are associated with the development of recurrent or new cancers.
