Abstract: | A prospectively recorded 5-year series of 254 patients receiving elective neck irradiation is evaluated. All had clinically negative necks and initial control at the primary site. Forty-seven percent of the patients had T3-4 tumours. Radiotherapy was delivered from a megavolt source at 2 Gy/day 5 days a week to a total dose of 46-50 Gy. All but 3 patients completed the treatment as planned. Neither tumour stage nor site of the primary tumour was related to the incidence of regional recurrences. Of 30 patients receiving 46-49 Gy, 5 died from neck node recurrences. Of 221 patients treated to 50 Gy or more, 16 (7.2%) developed regional recurrences. Two of these recurrences were avoided, giving a regional failure rate of 6.3%. As a whole, 7.8% died from regional, 11.4% from local, and 3.1% from distant recurrences. |
