Abstract

Regional intra-arterial chemotherapy in the treatment of high grade osteosarcomas is used to decrease the tumor volume and increase the amount of limb salvage surgeries. Combined neoadjuvant chemotherapy including systemic and regional infusion also decreases the risk oflocal recurrence and metastasis. Using combined intra-arterial and intra-venal chemotherapy good pathologic response was achieved in 81% of patients with 23% of complete necrosis. 5- year survival of 68% was achieved in children. Local recurrences where observed in 8,7% comparing to 27/5% in the group withjust adjuvant chemo. 5- year RFS and PFS were 66,8 % and 46.5% respectively. Regional chemotherapy maybe recommended for routine use due to high efficacy and low percent of complications.
