Abstract

PURPOSE
This study was performed to determine the outcome after treatment of osteosarcoma with intraarterial cisplatin as a preoperative chematherapy regimen.
MATERIALS AND METHODS
Twenty five patients with extremity osteosarcoma were treated with intraarterial cisplatin at Seoul National University Children's Hospital from January 1987 to April 1996. The dose of cisplatin was 130 mg/m2 and three to six courses were repeated two- to three-week intervals, Systemic doxorubicin was added to six of these patients. This was followed by surgical resection(limb salvage or amputation) and postoperative adjuvant chemotherapy.
RESULTS
Limb-salvage was possible in twenty of these twenty five patients. Pulmonary metastasis was present in five patients at diagnosis and developed later in three patients. In six patients treated with systemic doxorubicin, pulmonary metastasis was absent at diagnosis and during follow-up period. Local recurrence after limb salvage was occurred in one patient and treated with amputation and systemic chemotherapy. Seven patients died from pulmonary metastssis and one from unknown cause. The follow-up duration of these patients was three to eighty eight months(median twenty two months) and the overall five-year survival and event free survival rate were 62.1% and 57.5%, respectively.
CONCLUSION
These data demonstrate that intraarterial cisplatin can be used as an effective regimen preoperatively for pediatric patients with extremity osteosarcoma. The combined use of systemic doxorubicin is expected to improve survival in patients with pulmonary metastasis.
