Treatment of patients with metastatic osteosarcoma in the lungs

Summary. The analysis of the world approaches in the treatment of patients with osteosarcoma who developed lung metastases after combined treatment of a local tumor was performed. The results of our studies of the effect of second-line systemic chemotherapy and radical surgery in patients with osteosarcoma metastases in the lungs were presented. The results showed that the majority of treated patients showed more than a three-year survival, which indicates the need of radical treatment in this group of patients.
