Abstract
- Les maladies inflammatoires intestinales sont associees a une augmentation du risque de developper un cancer colorectal (CCR). La duree et l’etendue de la maladie sont des facteurs de risque importants, de meme que la presence d’une cholangite sclerosante primitive (CSP) et un diagnostic a une âge precoce. La chimioprevention du cancer vise a empecher, arreter ou renverser la phase d’initiation ou de progression des cellules neoplasiques vers le cancer. Un interet croissant a ete accorde aux agents chimiopreventifs potentiels dans la CCR sporadique et associee a la colite. Plusieurs etudes ont montre qu’une prise reguliere de 5-aminosalicylates peut apporter une certaine protection contre le developpement de la CCR dans les MICI. Chez les patients porteurs de colite ulcereuse ou de CSP, il a ete demontre que l’acide ursodeoxycolique pouvait reduire le risque de CCR. L’acide folique ne semble pas protecteur contre le cancer. Cet article donne un resume d’un grand nombre d’etudes de diverses provenances, epidemiologiques,in vivo etin vitro, qui ont etudie la question de la chemoprevention dans les MICI. Inflammatory bowel disease (IBD) is associated with an increased risk of developing colorectal cancer (CRC). Both duration and extent of disease are important risk factors, as is the presence of primary sclerosing cholangitis (PSC) and early age at diagnosis. Chemoprevention of cancer aims to prevent, arrest or reverse the initiation phase or the progression of neoplastic cells to cancer. A growing interest in possible chemopreventive agents, in both sporadic and colitisassociated CRC has occurred. Several studies have indicated that regular intake of 5-aminosalicylates can provide some protection against the development of CRC in IBD. In patients with ulcerative colitis and PSC ursodeoxycolic acid has been shown to reduce the risk of CRC. Folic acid has not been proven cancer protective in IBD. The current review gives an overview of the evidence of a variety of sources including epidemiological, in vivo, and in vitro studies that have addressed the question of chemoprevention in IBD.
