[Intestinal and extraintestinal malignancies in inflammatory bowel disease: case series from a tertiary center]

Inflammatory bowel diseases have recorded increasing incidence. A long period of illness and immunsuppressive drugs run a high risk of complications, this is particularly true for neoplasias.Medical records of patients with inflammatory bowel diseases who developed a malignant disease during 2000 and 2020 were used for analysis.51 patients could be included. 56% of tumors were located extraintestinal and occurred more often in patient with Crohn's disease. Neoplasias were more frequent in men (61 %).Individual prevention recommendations are urgently needed. Our focus should be extended to extraintestinal neoplasias. Initial diagnosis is often made in the 50+ age group. Thus, standardizised prevention programs including life-style factors should be started at the time of IBD diagnosis.
