Vinblastine, cisplatin and bleomycin as salvage therapy for refractory high-risk metastatic gestational trophoblastic...

Vinblastine, cisplatin and bleomycin (VPB) were utilized as salvage therapy in seven women with high-risk metastatic gestational trophoblastic tumors resistant to prior treatment with triple therapy (methotrexate, actinomycin D and cyclophosphamide) or the modified Bagshawe protocol. While four patients (57%) achieved sustained remission with VPB, surgery was performed on two of them to remove sites of resistant disease. The mean prognostic score for the patients who achieved remission was 10 versus 17 for those who died (P less than .05). Although severe hematologic toxicity occurred in five patients (71%), no deaths were attributable to toxicity. Since VPB has limited activity when used as salvage therapy, alternate chemotherapy protocols need to be developed for patients with refractory gestational trophoblastic disease.
