Abstract
The authors reviewed 164 cases of head and neck sarcoma from adult patients seen at the University of California, Los Angeles (UCLA), between 1955 and 1988. The median follow‐up was 70 months. Multivariate analysis demonstrated that tumor grade, size, and surgical margin status were the most important independent prognostic factors. Thirty‐one percent (27 of 85) of patients with high‐grade lesions were free of disease versus 81% (44 of 55) with low‐grade lesions at last follow‐up. Sixty‐seven percent (50 of 76) of patients with lesions smaller than 5 cm were free of disease versus; 38% (33 of 88) with lesions larger than 5 cm. In 16 patients, low‐grade lesions, measuring less than 5 cm and with negative margins histologically, were controlled with surgery alone. For the 94 patients whose primary tumors were treated at UCLA, local control was achieved in 52% (26 of 50) of patients treated with surgery alone and 90% (20 of 22) with combined therapy (surgery and radiation therapy [RT] with or without chemotherapy). Seventy‐five percent (6 of 8) of patients with positive surgical margins treated with post‐operative RT achieved local control versus 26% (5 of 19) of patients receiving no additional treatment. In conclusion, surgery alone appears to be adequate treatment for small, low‐grade tumors and negative surgical margins. Patients with incomplete resection or high‐grade tumors should receive aggressive treatment–surgery and RT.
