Abstract
Leuprolide acetate (Lupron, TAP Pharmaceuticals, North Chicago), a gonadotropin-releasing hormone analogue, was administered subcutaneously at a 1-mg dose for a minimum of 8 weeks to 23 patients with refractory epithelial ovarian cancer. Eighteen of these patients were evaluable. There were no complete responses. Four patients (17%) had a partial response, with a median duration of 52 weeks. Three of six patients with grade 1 carcinomas had a partial response and two had stabilized disease. There was only one response among 15 patients with grade 2 or 3 disease. Therapy was well tolerated, with three patients complaining of hot flashes and two of mild pedal edema. Leuprolide acetate thus shows evidence of antitumor activity against refractory grade 1 epithelial adenocarcinoma of the ovary. Further trials with larger numbers of patients should be conducted.
