During the past 15 years, dramatic changes have been made in the treatment of osteosarcoma. The survival rate of patients with osteosarcoma has improved as a result of better adjuvant chemotherapeutic regimens [1–3]. There are many other factors, however, that have been shown to influence the prognosis of this disease, among them the patient’s age, site and size of the lesion, chemotherapeutic regimens, and surgical procedures [4–9]. We recently reviewed all cases of conventional osteosarcoma treated at Chiba Cancer Center, and analyzed the clinical prognostic factors of this disease.
