Increased prostaglandin synthesis has been implicated as a causative factor in the production of radiation induced enteritis. Seventeen patients selected to begin pelvic irradiation for treatment of gynecological cancer had plasma Prostaglandin E, Prostaglandin F, and 13, 14 dihydro 15 keto PGF2 alpha metabolite determined by radioimmunoassay, prior to initiation of radiotherapy, at weekly intervals during treatment and at six weeks following completion of radiotherapy. A total of 362 prostaglandin determinations were performed. Thirteen patients (76%) developed significant diarrhea consisting of three or more watery bowel movements per day. Nine patients (53%) had intermittent colicky pain and six patients (35%) had nausea and vomiting during treatment. Statistical evaluation revealed no significant elevation of plasma prostaglandins during radiotherapy.
