Stage II B형 골육종에 대한 술전 항암화학요법 및 수술적 치료 결과 = CLINICAL RESULTS OF NEO-ADJUVANT CHEMOTHERAPY AND SURGERY ON OSTEOASRCOMA

다국어 초록 (Multilingual Abstract)

Recent advances in imaging techniques, surgery and combination anti-cancer chemotherapy have brought high survial rates in osteosarcoma.
To investigate the survival rate, local recurrence and complications in treatment, we analysed 25 osteosarcoma cases who had been treated with preoperative neo-adjuvant chemotherapy, surgery and post operative chemotherapy at Department of Orthopedic Surgery, Catholic University. From May 1988 to April 1995, 42 cases of stage IIB osteosarcoma were admitted in Department of Orthopedic surgery. Among them, 17 cases who didn't follow our treatment guidance were excluded in this study.
The average age were 19 years. There were 21 males and 4 females.
The involved sites were 4 humerus, 10 femur, 10 tibia and 1 talus. Eleven cases had received intra-arterial cisplatin and intravenous adriamycin chemotherapy, and 7 T-10 protocol and 7 intravenous ifosfamide, ADR, methotrexate, cisplatin. Among twenty-three cases were treated with limb salvage surgery, and 2 amputation. The average follow-up was 35 months(3-82). There were 14 cases of continuous disease free, 9 cases of died of desease, 1 case of alive with disease, and 1 case of no evidence of disease at final follow-up. There were three cases of local recurrence at 6,8 and 12 months after operation. The Estimated kaplan-Meier's 5 year survival rates for all, ADR-cisloatin group, T-10 protocol group, and ifosfamide regimen group were 66%, 73%, 44% and 72%, respectively.
