Abstract

Background and Objectives: There are many factors thought to have an influence on the prognosis of osteosarcoma that have been reported in the literature. Their significance, however, still remains controversial in most cases. Experience with osteogenic sarcoma (OS) was reviewed in order to evaluate surgical results and survival and to determine the prognostic factors. Methods: Ninety-six patients with high-grade osteosarcoma of the extremities were treated between 1986 and 1997 in the authors' institution. They were divided into 3 groups: In group I, all 75 patients with non- metastatic OS received intensive chemotherapy (high-dose methotrexate, doxorubicin, ifosfamide, and cisplatin) and underwent surgery. In group II, 9 patients already had metastases at the time of referral. In group III, 12 patients received chemotherapy in delayed or suboptimal form. Results and Conclusions: In group I, there were local recurrences in 3 patients (7%) and metastases in 8 patients (20%) with limb-saving, whereas these numbers were 1 (3%) and 14 (38%) in those who had amputation. The 5-year disease-free survival (DFS) was 72% and 69% in the limb-saving and amputation groups, respectively. In groups II and III, 5-year DFS was extremely poor, 10% and 20% only, underlining the importance of stage and intensity of chemotherapy, respectively. With univariate analysis, sex, duration of symptoms, and radiographic appearance of OS had no prognostic value, whereas tumor volume <60 cm3, wide or radical surgical margin, distal location of OS, cartilagineous ground substance <20%, and response to chemotherapy were positive prognostic factors. The last 4 variables maintained their significance in the multivariate Cox model as well. Age >30 years showed indirect negative influence on the final outcome through enhanced intolerability to the drugs and less cooperability of the patients. The results on survival with limb-saving surgery were well comparable with those of amputation. (C) 2000 Wiley-Liss, Inc.
