Ovarian carcinoma: abdominopelvic irradiation following reexploration

Twenty patients with ovarian cancer, who following reexploration were left with residual disease nodules of less than 2 cm diameter, received abdominopelvic irradiation. Of these patients 18 had previous chemotherapy. Fifteen patients completed treatment, 13 of whom had prior chemotherapy. Six of the 18 patients with invasive tumors were alive and disease free 18-53 months postradiotherapy, while only 4 patients had died at the time of follow-up. No patient with residual nodules greater than 1 cm remained disease free. There was no difference in outcome between patients with microscopic or macroscopic less than 1 cm residuum. Complications were acceptable with 3/20 (15%) developing treatment-related intestinal obstruction.
