Abstract

The results of 131 cases of classic non-metastatic osteosarcoma of the extremities treated with preoperative chemotherapy, surgery and postoperative chemotherapy are reported. Preoperatively, the patients were given Methotrexate (MTX) intravenously (high and average doses) and Cisplatinum (CDP) intraarterially. For postoperative chemotherapy, the drugs and treatment protocols were based on the degree of necrosis observed (good, fair, poor). Conservative surgery was performed in 73% of the cases and amputation in 27%. At an average 30 months follow-up (9-48 months) 59.5% of the patients had remained disease-free, 37.5% had developed metastases, and 3% had developed local recurrence. The percentage of disease-free patients was higher for those treated with high doses of MTX (68% vs. 51%) and for those in whom preoperative chemotherapy had induced good necrosis (75% vs. 44%). Neither the age or sex of the patients, nor the site of the tumor type of surgery performed influenced prognosis.
