Sulindac suppression of colorectal polyps in Gardner's syndrome.

Sulindac causes both regression and suppression of colorectal polyps in patients with Gardner's syndrome and familial polyposis coli. Three patients with Gardner's syndrome and multiple colonic polyps had complete regression of polyps after two to three months of sulindac therapy. The implication that sulindac may prevent colorectal cancer and prophylactic surgery in patients with hereditary polyps of the colon is intriguing but has not yet been substantiated.
