The reirradiation of recurrences of head and neck cancer.

The clinical results of reirradiation with 60Co of recurrences of head and neck cancer in 20 patients are presented. Fourteen patients, i.e. 70%, survived three years after reirradiation and ten patients, i.e. 50%, were symptom-free. Necrosis developed in four patients (20%). Reirradiation seems to be valuable and a relatively safe treatment of patients with inoperable recurrences of head and neck cancer.
