Colonic polyps in patients with acromegaly.

Abstract

Seventeen patients with acromegaly were prospectively studied with barium enemas and colonoscopy to investigate the possibility that acromegaly is associated with an increased frequency of colonic polyps and colon cancer. Polyps were identified in nine patients and were removed and examined in eight. In five patients the polyps were adenomatous, and in four of the five there were multiple polyps. The presence of polyps closely correlated with the presence of skin tags (p = 0.041) and also with the age of the patient (p less than 0.01). No new cases of colonic cancer were discovered; however, reviewing the records of 44 patients with acromegaly, four cases were previously diagnosed with colon carcinoma. This study identifies a unique group of patients that are at risk for the development of colonic polyps and perhaps colon cancer.
