    Abstract:
    PURPOSE: To evaluate the outcome of patients treated for soft tissue sarcoma using three different post-operative radiotherapy schedules. METHODS AND MATERIALS: Between 1990 and 2003, 89 patients (median age 50.8 years) presenting with soft tissue sarcoma (located to the limbs for 66 of them) underwent post-conservative-surgery radiotherapy. Pathology was liposarcoma in 35 cases and 54 others tumors. Tumors grades (FNCLCC classification) were 1, 2, 3 or unknown in 29, 32, 19 and 9 cases, respectively. Surgery was considered as complete in 68 patients. Irradiation was normofractionated (NF) in 62 cases, hyperfractionated (BF) in 19 cases and hypofractionated (HF) in 8 cases. For all the patients, median delivered dose was 61 Gy [34-76 Gy]. RESULTS: Median follow-up of alive patients was 73,8 months [3-184]. Five-year local control (LC) and overall survival (OS) rates were 85.5 and 71.2% respectively. According to multifactorial analysis, favourable prognostic factors were for local control, complete surgery (P=0.0075) and for overall survival, complete surgery (P=0.0267), grade 1 tumor (P=0.012) and absence of distant recurrence (P=0.0488). There was no statistical evidence of difference for the five-year LC and OS rates between the patients who received NF, BF or HF. There were few complications and there were comparable in the three groups. CONCLUSIONS: This retrospective serie showed similar results for all the schedules. There is no evidence to recommend bifractionation. Hypofractionation should be used only in selected patients with poor performans status.
