Indomethacin and ascorbate inhibit desmoid tumors

Abstract

Abstract Administration of indomethacin caused complete resolution of a desmoid tumor after a partial response to radiation. In another patient, this drug caused an immediate response, then became ineffective. When large doses of ascorbic acid were given with indomethacin, slow resolution of the tumor began and has continued for 14 months. Treatment of a third case with indomethacin and ascorbic acid from the beginning produced shrinkage of the tumor which has continued to date.
