Abstract: | Pulmonary metastases have been curative in some patients of osteosarcoma with aggressive surgical excision and intensive chemotherapy. But several retrospective studies and randomized II studies did not prove survival advantages of advanced cases with bone and soft tissue sarcoma. In treatment for refractory and advanced osteosarcoma after conventional treatments, clinical phase II trials showed 20-30% response ratio of high-dose ifosfamide and etoposide combination or carboplatin combination. In soft tissue sarcomas, high-dose ifosfamide and doxorubicin have over 50% response rate to advanced soft tissue sarcoma and total surgical excision of residual lung metastases prolong the survival. But new drugs active to refractory sarcoma had not reported in a recent decade. |
