Survival Stats

Survival Rates: (from

Localized tumors
With current treatment, the 5-year survival rate for people with localized osteosarcoma is in the range of 60% to 80%. These cancers are more likely to be cured if they are resectable; that is, if all of the visible tumor can be removed (resected) by surgery. (For high-grade osteosarcomas that can be resected completely, chemotherapy is still an essential part of treatment. Without it, the cancer is still very likely to come back.)

Metastatic tumors
If the osteosarcoma has already spread when it is first found, the 5-year survival rate is about 15% to 30%. The survival rate is closer to 40% if the cancer has spread only to the lungs (as opposed to having reached other organs), or if all of the tumors (including metastases) can be removed with surgery.
