Risk Factors and Clinical Outcomes in Patients with IBD with Melanoma

This study aims to (1) identify risk factors for melanoma development in patients with IBD, (2) compare clinical characteristics of melanoma in patients with IBD to the general population, and (3) assess the influence of immunosuppressive medication on survival. Methods: We retrospectively searched the Dutch Pathology Database to identify all Dutch patients with IBD with cutaneous melanoma between January 1991 and December 2011. We then performed 2 case–control studies. To identify risk factors for melanoma development in IBD, we compared patients with IBD with melanoma to the general IBD population. To compare outcome and survival after melanoma diagnosis, we compared cases with non-IBD melanoma patients. Results: We included 304 patients with IBD with melanoma, 1800 IBD controls, and 8177 melanoma controls. IBD cases had more extensive IBD (ulcerative colitis: pancolitis: cases 44.5% versus IBD controls without melanoma 28.1%; P
