Abstract

Thirty patients found to have residual epithelial ovarian cancer at second-look laparotomy were treated with whole abdominal radiation as salvage therapy. Dosage fractions were 120 rad per day until 3000 rad were delivered, then the pelvis was boosted to 5000 rad at 180 rad per day. Fourteen patients (47%) completed therapy without interruption and seven (23%) completed therapy with interruptions due to myelosuppression ranging from one to four weeks. Therapy was not completed in nine patients (30%). Four of 16 patients (25%) with microscopic residual disease before radiation remain alive and free of disease at 22 to 41 months. Two of six (33%) patients with minimal (less than or equal to 5 mm) residual disease remain alive and free of disease 19 to 40 months after radiation treatment. Patients with residual nodules greater than 5 mm uniformly did poorly. Patients who progressed on primary chemotherapy had a median survival of seven months, compared with more than 38 months for chemotherapy responders. Chronic bowel morbidity was a significant problem, with 30% of patients surviving at least four months from completion of radiation requiring laparotomy for small bowel obstruction. These preliminary results suggest that whole abdominal radiation may be useful in the management of patients who have responded to primary chemotherapy, but the benefit is confined to those patients who have minimal or microscopic disease at second-look laparotomy.
