The use of indomethacin, sulindac, and tamoxifen for the treatment of desmoid tumors associated with familial polyposis

Seven familial polyposis patients with desmoid tumors were treated with indomethacin, sulindac, or tamoxifen either as single agents or in combination. Serial computed tomographic (CT) scan examination was employed for objective measurement of tumor size since physical examination alone was an inaccurate means to evaluate intraabdominal and retroperitoneal desmoids. Only one patient with minimal tumor burden demonstrated a favorable response with complete resolution of an abdominal wall desmoid.
