Abstract. Background: Despite improvements in Development of chemotherapy and surgery has resulted in chemotherapy and surgery in the treatment of osteosarcoma, the considerable improvement of survival rates of satisfactory results are still difficult to achieve. New therapeutic osteosarcoma patients (1), the current chemotherapeutic modalities need to be developed for the improvement of these agents still have a lot of problems to overcome, such as treatments. TRAIL (TNF-related apoptosis inducing ligand) is serious side-effects or resistance to multiple chemo- known as a selective apoptosis inducer in most tumor cells, but therapeutic agents in 20-30% of the patients (2). New not in normal cells. Therefore, TRAIL is a good candidate therapeutic modalities for these patients are driven by target for the treatment of tumors.
