- W3210173192 abstract "Introduction: Previous studies have demonstrated that exposure to anti-TNFα medications or immunomodulators (IMM) does not increase the risk of new or recurrent cancer in patients with inflammatory bowel disease (IBD) and a previous history of cancer. There is little data regarding this risk after the use of newer biologics such as ustekinumab and vedolizumab. In this study, we assessed whether patients with IBD and a history of previous cancer who are exposed to these newer agents have an increased risk of developing subsequent cancer. Methods: We performed a retrospective cohort study of patients with IBD and cancer from a single academic medical center between January 2013 and December 2020. We recorded information on demographics, cancer type and treatment, and IBD characteristics and drug exposures. The primary exposure was type of IBD monotherapy after a cancer diagnosis. The primary outcome was development of new or recurrent cancer. Results: Of 401 patients with IBD and a history of cancer, 37 subsequently received vedolizumab, 14 ustekinumab, 31 IMM, 41 anti-TNF, 11 combination anti-TNF with an IMM, and 267 were not exposed to any immunosuppression following a cancer diagnosis (Table 1). There were no differences in duration of IBD, median age at cancer diagnosis, or smoking history. During a total median follow-up of 52 months, 81 (20%) patients developed incident cancer including 6 (16%) exposed to vedolizumab, 2 (14%) to ustekinumab, 3 (10%) to IMM, 12 (29%) to anti-TNF, 2 (18%) to combination anti-TNF with an IMM, and 56 (21%) with no immunosuppression (P = 0.41). Sensitivity analyses assessing any history of exposure to vedolizumab or ustekinumab, inclusive of both single and multiple biologic exposures, also did not reveal an increased rate of incident cancer. Conclusion: In this single-center study, vedolizumab or ustekinumab monotherapy in patients with IBD and a history of cancer was not associated with an increase in new or recurrent cancer compared with anti-TNF, IMM, or no immunosuppression. Prospective studies are needed to confirm this conclusion.Table 1.: Proportions reported as no. (%).
