Neoplastic colonic polyps in acromegaly.

A high prevalence of neoplastic colorectal polyps has been described in acromegalic patients. The aim of the present report was to confirm the high prevalence of neoplastic colorectal polyps in acromegaly and the existence of special risk factors for this type of polyps among acromegalic patients. A fiberoptic colonoscopy was performed in 27 active acromegalic patients, followed by both polypectomy and biopsy when indicated. Several prognostic variables were analysed a potential risk factors, in all cases. The prevalence of neoplastic colorectal polyps found in our series (22.2%) was similar to that in previous studies, and did not show any apparent increment compared to that in the populations in which it is known. None of the prognostic variables studied were related to the presence of neoplastic colorectal polyps.
