In this study, our objective was to determine whether 6 months of open- label therapy with sulindac 400 mg/daily or piroxicam 20 mg/daily promote regression of adenomatous colonic polyps left in situ. Left-sided colonic polyps (size 3-12 mm) detected at colonoscopy were measured and left without being biopsied. The bowel wall opposite to the polyps was marked with India ink submucosally. Patients were assigned to drug therapy, and compliance was determined by pill count. Polyps were measured during sigmoidoscopy after 3 and 6 months of treatment; polyps were removed at the 6-month examination. Examiners were not blinded to drug therapy or previous polyp measurements. Seven patients completed 6 months of therapy (five sulindac and two piroxicam). Two additional patients treated with piroxicam were withdrawn secondary to adverse events (bleeding gastric ulcer and rash). In one patient treated with sulindac, a 6-mm polyp disappeared, and two other polyps seemed to regress partially. One polyp regressed partially in a piroxicam-treated patient. All other polyps remained unchanged. Conclusions: We did not observe dramatic regression of sporadic colon adenomatous polyps to either sulindac or piroxicam after 6 months of therapy in this small uncontrolled pilot study.
