A case of combination treatment of femoral osteosarcoma

Osteosarcomas are rare tumors with aggressive biology. It is important to refer such patients to a high-volume center, where an accurate diagnosis and optimal treatment are more likely to be performed. In contrast to Ewing's sarcoma, conventional osteosarcomas are believed to be generally resistant to radiation therapy, and the main treatment modalities are surgery and chemotherapy. In this clinical case, we demonstrate the efficacy of combined treatment of osteosarcoma of the femur.

Preoperative chemotherapy allowed to evaluate tumor sensitivity to systemic treatment in vivo and optimize adjuvant treatment after R0 resection which allowed to achieve complete clinical response to treatment.
