Management of Inflammatory Bowel Disease with History of Cancer.

Background/Objectives: Because of the chronic course of the disease, clinicians managing IBD frequently encounter patients with a prior or newly diagnosed cancer. This can be related to the specific background cancer risk in that subject, aging, familial/genetic factors, or ongoing chronic inflammation. However, a potential influence of some therapeutic agents should also be considered. This setting, in the absence of controlled trials and few open series reports available, raises issues such as correct screening, prevention, and surveillance, but also eventual modification or adaptation of the medical management. Methods and Results: Few consensus guidelines and studies are available on the management of IBD patients with a history of cancer, and therefore, we aim to review the recommendations of the current guidelines and the evidence reported in the most recent real-world cohorts. Conclusions: This review will offer (a) an understanding of the background of cancer risk in IBD patients; (b) analysis and discussion of the risk of cancer related to IBD therapy; and, finally, (c) some clues for the management of IBD in patients with a previous or current history of cancer.
