title: The reirradiation of recurrences of head and neck cancer.
abstract: 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.
