Current and future therapeutic approaches for osteosarcoma

ABSTRACTIntroduction: Current treatment of osteosarcoma includes surgical resection of all gross disease in conjunction with systemic chemotherapy to control micro-metastatic disease. This yields a 5-year event free survival (EFS) of approximately 70% for patients with localized osteosarcoma while patients with metastatic or recurrent disease fare poorly with overall survival rates of less than 20%.Areas covered: This review outlines the current and future approach towards the treatment of osteosarcoma. A literature search was performed utilizing PubMed. Several recent clinical trials are reviewed in detail, as is innovative research evaluating novel agents and surgical techniques which hold promise.Expert commentary: The outcome for patients with osteosarcoma has not changed in several decades. This plateau in survival rates highlights the need for a novel approach towards research. There remains a great deal of interest in utilizing the very high risk population of recurrent osteosarcoma patients to rap...
