Methotrexate with citrovorum factor rescue in gestational trophoblastic disease.

Thirty-three patients with gestational trophoblastic disease treated with methotrexate alone and 68 similar patients treated with methotrexate and citrovorum factor rescue were analyzed. Both groups showed a comparable sustained biochemical remission rate. The group treated with methotrexate and citrovorum factor however showed a shorter interval to induction of remission (p less than 0.05). Contrary to previous reports, the methotrexate and citrovorum factor regimen failed to protect the patients against the development of hepatic toxicity, the incidence of hepatic toxicity being significantly higher in the group treated with methotrexate and citrovorum factor.
