[A case of advanced mediastinal choriocarcinoma showing complete remission for two years by high-dose chemotherapy with peripheral blood stem cell transplantation].

A twenty-six-year-old male patient with advanced choriocarcinoma originated from mediastinum was treated by high-dose chemotherapy with peripheral blood stem cell (PBSC) transplantation. He had massive tumors in the cervical, mediastinal and bilateral lung fields. After 3 kur of PVeBV therapy (CDDP 60 mg x day 1-3, etoposide 160 mg x day 1-3, BLM 30 mg x day 1, VBL 12 mg x day 1), he obtained complete remission. PBSC was collected at the time of hematopoietic recovery and high-dose chemotherapy with PBSC transplantation was conducted because of the high possibility of recurrence. The hematopoietic recovery was rapid, and the patient remained well with no sign of recurrence for 24 months.
