Abstract

Abstract : Patients with adenomatous polyposis, usually defined as patients with >10 adenomatous polyps in the colorectum, are at increased risk for colorectal cancer (CRC). Since surgical and endoscopic treatment do not completely eliminate the potential for future polyps or extraintestinal neoplasms, there is an unmet medical need to identify pharmacological agents to delay major surgical interventions. We present two cases of patients with adenomatous polyposis who developed chronic myelogenous leukaemia and were treated with imatinib as part of their chemotherapy. A sustained regression of the colonic polyps documented in both cases was observed after the initiation of the tyrosine kinase inhibitor. Despite the presence of potential confounders, we hypothesise the potential role of imatinib as a chemopreventive agent in patients with familial adenomatous polyposis.
