Intra-operative radiotherapy--5 years of experience in the palliative treatment of recurrent and advanced head and neck cancers.
Recurrent and advanced cancer in the head and neck region is usually associated with limited therapeutic concepts and a dismal prognosis. Efforts mainly focus on palliative treatment in order to improve the patient's quality of life. From May 1989 to December 1994, a total of 120 intra-operative radiotherapy (IORT) procedures with high-energy electron beams (mean energy: 7 MeV: mean dose: 20 Gy) were performed in 95 patients. Therapy was usually performed under endotracheal anaesthesia (84%). There were 91 cases (75.8%) of recurrence in the lymph nodes of the neck and 14 cases (11.7%) of local recurrence. 15 patients (12.5%) received IORT as part of the initial treatment. Considering the palliative nature of IORT in these patients, only an R2 resection (gross residual tumour) was achieved in 71.7%. Local tumour control was nonetheless possible in 17% (R2 resection) to 64% (complete R0 resection), with a mean 11-month follow-up period for survivors (mean for deceased patients: 8 months). Regarding palliative criteria, IORT proved to be feasible since patients profited from short hospitalisation (median: 10 days), a low complication rate (27 instances; e.g. tracheostomy: 11; necrosis: 8, or fistula: 3) and, in part, a substantial reduction of pain (73.8%). Most of them regained physical and psychic integrity for weeks to months and were able to take part in social life during the final stage of their disease.
