Successful treatment generally requires the combination of effective systemic chemotherapy and complete resection of all clinically detectable disease. Protective weight bearing is recommended for patients with tumors of weight-bearing bones to prevent pathological fractures that could preclude limb-preserving surgery.

Randomized clinical trials have established that both neoadjuvant and adjuvant chemotherapy are effective in preventing relapse in patients with clinically nonmetastatic tumors.[1,2] It is imperative that patients with proven or suspected osteosarcoma have an initial evaluation by an orthopedic oncologist familiar with the surgical management of this disease. This evaluation, which includes imaging studies, should be done prior to the initial biopsy, since an inappropriately performed biopsy may jeopardize a limb-sparing procedure.
