AbstractUntil the 1970s, the survival rate of osteosarcoma patients was less than 20%. By the 1990s, this had improved to 60% to 70%, and limb-sparing procedures have replaced amputation in many patients thanks to effective combination therapy. Neoadjuvant chemotherapy has become an accepted practice in the majority of institutions using protocols which include MTX, ADR, BCD and CDDP as the most active agents against this disease. Newer agents, particularly IFM and ETP, are increasingly incorporated into complex regimens. While several studies have reported multivariate analyses to identify prognostic factors, the histologic response to preoperative chemotherapy remains the most important prognostic factor. Pulmonary metastases are the primary cause of death in patients with osteosarcoma. Although current treatment regimens allow effective salvage therapy for the patients with pulmonary metastases, the actuarial survival rate is 30%. A more effective systemic treatment for those patients is needed. The current management of osteosarcoma is critically reviewed and a treatment strategy is proposed for discussion.
