Overview
Surgery
- Cure, if achievable requires aggressive surgical resection often with amputation followed by chemotherapy.
- If a limb-salvage procedure is feasible, a course of multi-drug chemotherapy precedes surgery to downstage the tumor, followed by wide resection of the bone and insertion of an endoprosthesis.
- The outcome depend on different factors such as age, sex, site, size, and type but the most important predictor is the histologic degree of necrosis post induction chemotherapy; 90% histologic necrosis is associated with much better prognosis.
- Localized Osteosarcoma: Surgery. Combination chemotherapy is usually given before and after surgery. Surgery followed by radiation therapy when the tumor cannot be completely removed by surgery.
- Metastatic Osteosarcoma:
- Lung Metastasis: When osteosarcoma spreads, it usually spreads to the lung. Treatment of osteosarcoma and MFH with lung metastasis may include Combination chemotherapy followed by surgery to remove the primary cancer and the cancer that has spread to the lung.
- Bone Metastasis or Bone with Lung Metastasis: Osteosarcoma spread to a distant bone and/or the lung. Treatment may include Combination chemotherapy followed by surgery to remove the primary tumor and the cancer that has spread to other parts of the body. More chemotherapy is given after surgery. Surgery to remove the primary tumor followed by chemotherapy and surgery to remove cancer that has spread to other parts of the body.
