Abstract

A Head and Neck Sarcoma Registry was established by the Society of Head and Neck Surgeons to review treatment results of a rare tumor by surgeons with special interest in this anatomic site. Two hundred fourteen patients were analyzed. There were 194 adult tumors and 20 pediatric tumors. The major sites included parotid and neck, 20%; face and forehead, 18%; maxilla and palate, 13%; scalp, 12%; mandible, 11%; paranasal sinuses, 7%; larynx, 2%; and oral cavity, 5%. Eighty-four percent were resectable. The disease-free survival was 56%; overall survival was 70% at 5 years. Major determinants of survival were adequacy of resection (margins free of tumor) and tumor type. Survival differed according to tumor cell type (tumor grade was not available). Patients with chondrosarcoma and dermatofibrosarcoma had survival approaching 100%. Patients with malignant fibrous histiocytoma (MFH) and fibrosarcoma (FSA) had intermediate survival of 60% to 70%. The worst survival, less than 50% at 5 years, occurred in patients with osteosarcoma, angiosarcoma, and rhabdomyosarcoma in decreasing order. This suggests a rationale for identifying high-risk patients for prospective adjuvant protocols. This study emphasizes the value of recording uncommon tumors to provide relevant information for future study and possibly therapy.
