Methotrexate with leucovorin rescue in the treatment of gynecologic malignancies. Preliminary report

Experience with chemotherapy in advanced gynecologic malignancies is limited. In 6 patients, 2 of 4 with carcinoma of the cervix, and 1 patient with carcinoma of the ovary achieved partial remission when treated with a regimen of high dose methotrexate (240 mg/m2) followed by leucovorin rescue. On patient with metastatic trophoblastic disease achieved complete response (greater than 24 months). The number of doses of leucovorin 'rescue' was based on creatinine clearance. The advantage of rapid response and moderate toxicity indicate the need for further study of this regimen in the treatment of gynecologic malignancies.
