1977年6月～1978年7月在广西壮族自治区人民医院放疗鼻咽癌206例,5年生存率为42.2％。其中Ⅱ期患者为78.6％(33/42)不低于国内的报道。鼻咽肿瘤设两个耳前野为主野,颈淋巴结设前、后切线野以~(60)钴γ线放射治疗。70～79Gy组的患者5年生存率较高(60％)唯统计学处理无显著性差异(P>0.05)。常见的死亡原因为远处转移,早诊早治对增加远期疗效有重大意义。鼻咽肿瘤或颈部转移灶复发给予再程放疗有一定姑息价值。后遗症以张口困难为多见,它与放射剂量呈正相关。
From June 1977 to July 1978, 206 cases of nasopharyngeal carcinoma were treated in the People’s Hospital of Guangxi Zhuang Autonomous Region. The 5-year survival rate was 42.2%. Among the patients in stage II, 78.6% (33/42) were no less than domestic reports. Nasopharyngeal neoplasms consisted of two preauricular fields as the main field, and the cervical lymph nodes were set with gamma-ray (60) cobalt radiation before and after the tangential field. The 5-year survival rate of patients in the 70-79 Gy group was higher (60%). There was no significant difference in statistical treatment (P>0.05). The common cause of death is distant metastasis. Early diagnosis and early treatment are of great significance to increase long-term curative effect. Recurrent nasopharyngeal neoplasms or cervical metastases give relapse radiotherapy a certain palliative value. Sequelae are more common with difficult mouth opening. It is positively correlated with radiation dose.
