在放射治疗过程中和结束后的一段时间内,临床上观察到癌肿逐步退缩乃至消失,其消退情况与放射剂量相关性如何?本文根据本组鼻咽癌首程根治性放射治疗后鼻咽部原发病灶和颈上部转移淋巴结获得五年局控的病例资料分析,对此进行探讨。 本组鼻咽原发灶五年局控608例、颈上部转移淋巴结五年局控617个结的资料来自我科从1977年7月至1980年底在我科进行首程根治性放射治疗的鼻咽癌1882例。本文对颈部转移淋巴结只限于观察、分析上颈深淋巴结,两侧分别记录和比较,如一侧不止一个肿大淋巴结则观察其最大者,共2254个。全部病例按常规用钴外照射治疗机对鼻咽部
During and after the radiation therapy, the cancer gradually receded or even disappeared clinically. What is the correlation between the remission and the radiation dose? This article according to this group of radical radiotherapy of nasopharyngeal carcinoma after first radical treatment of nasopharyngeal The primary lesions and metastatic lymph nodes in the upper part of the neck were analyzed for the five-yearly controlled case data analysis. The data of 608 cases of primary nasopharyngeal primary lesions and 617 lesions at the upper cervical metastasis node during the past five years were obtained from the first radical radiotherapy in our department from July 1977 to the end of 1980 in our department. There were 1882 cases of pharynx cancer. In this article, lymph node metastasis of the neck is limited to the observation and analysis of deep cervical lymph nodes. Both sides are recorded and compared, respectively. If there is more than one enlarged lymph node, we observe the largest of them, a total of 2254. All cases were routinely treated with a cobalt external irradiation treatment machine for nasopharyngeal
