作者从1981年～1984年对34例转移性颈淋巴结大于40mm,不能手术切除的患者,作了加速照射的研究,均为中度或高分化的鳞癌。方法先用~(60)钴以二个平行对穿野照射全颈,如考虑原发灶来自咽部,咽部也一并包括在照射野内,日剂量2GY,共50GY/25次/ From 1981 to 1984, the authors performed accelerated irradiation studies on 34 patients with metastatic cervical lymph nodes larger than 40 mm that could not be surgically removed. All of them were moderately or well-differentiated squamous cell carcinomas. METHODS: Firstly, the whole neck was irradiated with ~(60)cobalt with two parallel pairs of fields. If the primary lesion is considered to be from the pharynx, the pharynx is also included in the irradiation field. The daily dose is 2GY, for a total of 50GY/25 times/
