Integrating radiation therapy in the curative management of ovarian cancer: current issues and future directions.

Overview

Although important advances in surgery, chemotherapy (CT), and radiation therapy (RT) have been made, overall survival for patients with ovarian cancer (OC) has not changed significantly. Despite its long history in the treatment of OC and its proven curative role in patients with microscopic or minimal residual disease, the proper role of RT in the management of OC is not clearly established. Although the use of primary adjuvant RT (whole abdominal irradiation) has declined in the last 15 years, there has been a resurgence of interest in RT as part of a combined modality approach and as salvage therapy for patients with small-volume persistent disease after primary cytoreductive surgery and platinum-based CT. This article reviews the evidence supporting the use of RT alone or combined with chemotherapy as primary adjuvant therapy or in the salvage setting. Current issues in the radiotherapeutic management are discussed along with ideas for future clinical research directions.
