PURPOSE: The main objectives of this study were (a) to review the treatment results of primary head and neck soft-tissue sarcoma at our institution, (b) to identify important prognostic factors in local control and survival, and (c) to assess the efficacy of salvage therapy. METHODS AND MATERIALS: Sixty-five patients were treated at the University of California, San Francisco, between 1961 and 1993. Seventeen patients (27%) had low-grade, 10 (15%) had intermediate-grade, and 38 (58%) had high-grade sarcomas. Tumors were > 5 cm in 35 patients. Local management consisted of surgery alone in 14 patients (22%), surgery and radiotherapy in 40 (61%), and radiotherapy alone in 11 (17%) patients. The median follow-up was 64 months. RESULTS: The 5-year actuarial local control rate of the entire group was 66%. Tumor size and grade were important predictors for local control on multivariate analysis. The actuarial local control rate at 5 years was 92% for T1 vs. 40% for T2 primaries (p = 0.004), and 80% for Grade 1-2 vs. 48% for Grade 3 tumors (p = 0.01). None of the patients treated with radiotherapy alone with a dose of 50-65 Gy were controlled locally. Combined radiotherapy and surgery appeared to yield superior local control compared to surgery alone (77% vs. 59%); however, the difference was not statistically significant. The 5-year actuarial overall and cause-specific survivals were 56% and 60%, respectively. Unfavorable prognostic factors for cause-specific survival on multivariate analysis were age > 55 (p = 0.009), high tumor grade (p = 0.0002), inadequate surgery (p = 0.008), and positive surgical margins (p = 0.0009). In patients who underwent salvage therapy for treatment failure, the 5-year actuarial survival after salvage treatment was 26%. CONCLUSION: Tumor size and grade were important predictors for local control. Age, grade, adequacy of surgery, and status of surgical margins were significant prognostic factors for survival. There was a trend of improved local control with combined surgery and radiotherapy compared to either modality alone for high-risk patients. Radiotherapy alone with doses < or = 65 Gy was insufficient for control of gross disease. Aggressive salvage therapy was worthwhile in patients whose disease was uncontrolled after the initial treatment.
