Ten year's experience with methotrexate and folinic acid as primary therapy for gestational trophoblastic disease.
Methotrexate and folinic acid was administered as primary therapy in 185 patients with gestational trophoblastic disease between 1974 and 1984. Methotrexate and folinic acid induced complete remission in 147 (90.2%) of 163 patients with nonmetastatic disease and in 15 (68.2%) of 22 patients with low-risk metastatic disease. Sustained remission was achieved in 132 (81.5%) patients following only one course of chemotherapy. All patients with methotrexate resistance subsequently achieved remission with Actinomycin D or combination chemotherapy. Methotrexate when administered with folinic acid was associated with granulocytopenia, thrombocytopenia, and hepatotoxicity in 11 (5.9%), 3 (1.6%), and 26 (14.1%) patients, respectively. The human chorionic gonadotropin (hCG) regression curve served as a reliable guide for the administration of chemotherapy and enabled the attainment of a high remission rate while limiting chemotherapy exposure. Methotrexate and folinic acid achieves an excellent therapeutic outcome with limited chemotherapy exposure and effectively limits systemic toxicity.
