title: Is there a risk for lymphoma or extracolonic cancer in patients with inflammatory bowel disease?
abstract: An important issue in the management of inflammatory bowel disease (IBD) is the risk for lymphatic or extracolonic malignancies reported in patients receiving prolonged immunosuppressive therapy and/or therapies with biological agents. Azathioprine (AZA), 6-mercaptopurine (6-MP), methotrexate. and anti-TNF (infliximab, adalimumab) are reference drugs for IBD forms unresponsive to conventional therapies. The administration of these drugs is a high responsibility because IBD itself is associated with an increased risk for cancer, namely colon cancer. The possibility of a drug-induced additional risk remains controversial, the relative risk for lymphoma being estimated at 1.2%. For extracolonic malignancies, there are variations in standardized incidence per reference population in terms of location (skin, liver and biliary tract, uterine cervix, prostate, etc.), and also IBD phenotype (ulcerative colitis or Crohn's disease). The uncertainty regarding the occurrence of neoplasia in IBD patients for many years on immunosuppressive therapy and/or biological agents is a strong argument both for treatment discontinuation and it's monitoring by inclusion in screening programs. In this paper we aimed to approach the conceptual model risk-benefit in the therapy with imunosuppressive and biological agents given the controversies in the literature generated by the drug-induced risk for malignant lymphatic and extracolonic tumor in patients with IBD.
