Hyperthermic isolated regional perfusion for the treatment of osteosarcoma in the lower extremity - 08/09/11
Abstract |
Background: In order to reduce the systemic toxity of cisplatin and to increase the effect on the local tumor, facilitating limb-preserving procedures, we have been using hyperthermic isolated regional perfusion (HIRP) for the treatment of osteosarcoma in addition to preoperative chemotherapy.
Materials and methods: Twenty patients with an osteosarcoma in a lower extremity were treated with both preoperative chemotherapy and HIRP.
Results: The chemotherapeutic effects of preoperative chemotherapy with HIRP was grade III in 6, and grade IV (no viable cell areas observed) in 7. The surgical margins could be reduced in these 13 cases of good responders showing over 90% necrosis (grade III or grade IV), which mainly involved postnecrotic fibrosis and osteosclerosis.
Conclusion: HIRP can help to control the tumor locally. A more conservative operation was then possible in cases of good responders to preoperative chemotherapy with HIRP.
