[Evidence-based chemotherapy for patients with bone and soft part sarcoma]

In the present paper, we review the evidence for chemotherapy in patients with bone and soft part sarcoma and discuss the contributions and improvements made by chemotherapy to the treatment of patients with bone and soft part sarcoma. In the osteosarcoma and Ewing's sarcoma family, neoadjuvant and adjuvant chemotherapy have improved the 5-year disease-free survival to 60%, and limb-salvage operations have improved this to 70-80% in cases of non-metastatic malignant bone tumor. Several trials were conducted in order to overcome rate relapses and metastatic bone sarcoma. With osteosarcoma, thoracotomy improved the survival of lung metastatic patients, but CDDP-ADM branch switched according to the neoadjuvant chemotherapy and failed to elevate the continuous disease-free survival of patients. Dose intensive use of cytotoxic drugs with G-CSF or autologous bone marrow transplantation and multidrug programs were conducted in preliminary studies and achieved favorable results in a high risk factors group for tumors of the Ewing's sarcoma family. Surgical techniques have brought improvements in the treatment of soft tissue sarcoma, but there has been no impact by chemotherapy. Ifosfamide and adriamycin combination is being evaluated in the treatment of local advanced and metastatic soft part sarcoma by local control rate or survival from relapse.
