A comparison of methods of loco-regional chemotherapy combined with systemic chemotherapy as neo-adjuvant treatment of osteosarcoma of the extremity.
摘要：
Our experience of pre-operative intraarterial (i.a.) vs intravenous (i.v.) infusion of cisplatinum (CDP) in a multiagent neo-adjuvant chemotherapy for osteosarcoma of the extremity is reported. Two successive randomized studies were performed. In the first, pre-operatively, CDP i.a. vs CDP i.v. was applied in combination with high-dose methotrexate (HDMTX) and adriamycin (ADM) within a three-drug regimen. In the second, a combination of HDMTX, ADM and IFO, within a four-drug regimen was tested. The rate of responses to chemotherapy (tumour necrosis > or = 90%) was significantly higher (P<0.04) for the 142 patients treated with the four-drug regimen than in the 79 patients treated with a three-drug regimen (76%vs 62%). According to the route of CDP infusion, in the three-drug regimen the rate of responses was significantly higher (P=0.004) in patients treated with i.a. CDP (77%) than in patients treated i.v. (46%); with the four-drug regimen the rate of response was not significantly different in patients treated i.a. (81%) and in patients treated i.v. (71%). No significant differences in the rates of limb salvages, local recurrence and event-free survival (EFS) were seen between the i.a. and the i.v. groups. In the treatment of osteosarcoma of the extremity, the i.a. infusion of CDP does not offer any significant advantage when this drug is used within an aggressive, multiagent, pre-operative four-drug regimen.
