Treatment of ovarian stromal tumors.

Fifty-one patients with granulosa-cell tumors and nine patients with Sertoli-Leydig-cell tumors have been treated at the M. D. Anderson Hospital. The most important prognostic finding was the stage of the tumor when first seen. Conservative surgery was utilized in young patients with lesions confined to one ovary. More advanced tumors were treated with maximal tumor resection and postoperative treatment with either irradiation or chemotherapy. Postoperative radiation was given when the tumor capsule had ruptured or residual tumor less than 2 cm. in diameter was present after surgery. Single-agent chemotherapy was ineffective in ovarian stromal tumors, but combination chemotherapy was found to be effective in advanced or recurrent stromal tumors. Actinomycin-D, 5-fluorouracil, and cyclophosphamide were effective in granulosa-cell tumors. Vincristine, actinomycin-D, and cyclophosphamide were effective in Sertoli-Leydig--cell tumors.
