High-dose chemotherapy with autologous bone marrow transplantation for refractory metastatic gestational trophoblastic disease.

A patient with gestational trophoblastic disease failed to respond to all standard multiple-agent chemotherapy and had progressive uterine disease. Total hysterectomy also proved ineffective. We therefore administered high-dose cyclophosphamide, etoposide, and melphalan with autologous bone marrow support. Severe marrow suppression followed but a complete remission was achieved and the patient remains free of disease 3 years after the completion of therapy. This result seems to confirm the value of using high-dose multiagent therapy to optimize the dose-effect of therapy regimens on drug-refractory gestational trophoblastic disease.
