    Abstract:
    Sarcoma of the head and neck region following irradiation for primary malignancy other than retinoblastoma has rarely been reported. Three cases of postirradiation sarcoma arising in the head and neck region following definitive radiotherapy for primary malignancies of the nasal cavity, paranasal sinuses, and larynx are presented. The intervals from initial radiation to diagnosis of sarcoma were 10 years, 10 1/2 years, and 12 1/2 years, respectively. The dosage ranged from 6000--6400 rads using conventional fractionation (1750--1811 ret) on a 60Cobalt teletherapy unit. Methotrexate (25 mg I. V. every three days for seven doses) was utilized during the initial course of radiation in two of the three patients. The cases conform well to established criteria for the diagnosis of radiation-induced sarcoma. Postirradiation sarcoma of the head and neck region is a remote hazard that must be weighed against the benefits of curative radiation therapy, particularly when treating in the presence of bone disease or when treating retinoblastoma or benign lesions.
