[High-dose chemotherapy with autologous peripheral blood stem cell transplantation (PBSCT) for refractory bone and soft tissue sarcomas].
High-dose chemotherapy with autologous peripheral blood stem cell transplantation was administered to 10 patients with refractory bone and soft tissue sarcoma (2 patients with primitive neuroectodermal tumor, 4 patients with Ewing's sarcoma, 3 patients with synovial sarcoma and one patient with osteosarcoma). Busulfan 4 mg/kg x 4, melphalan 140 mg/m2 and thiotepa 200 mg/m2 x 3 were used in the high-dose chemotherapy. Complications related to the treatment were limited to one patient who developed hepatic veno-occlusive disease, no serious complications were seen in the other patients. Four patients died of their disease, one patient was alive with the disease and 5 patients were alive with no evidence of disease. The prognosis for non-resectable primitive neuroectodermal tumor and Ewing's sarcoma is said to be very poor. However, there are some patients in whom the disease is kept in remission by high-dose chemotherapy with autologous peripheral blood stem cell transplantation, so this therapy may be a possible substitute for radical operation. With spindle cell sarcomas, the efficacy of this treatment was temporary, so it will be necessary to investigate frequent high-dose chemotherapy and to change the high-dose chemotherapy regimen.
