鼻咽癌是南方诸省高发恶性肿瘤,放射治疗为鼻咽癌的主要治疗手段,但常规根治放疗以后仍有13%~30%鼻咽癌原发灶残留,为促进鼻咽癌肿瘤的消退,减少复发可能,同时避免对过量外照射引起的放量后遗症发生,我院引进了GZP6型微机控制式钴60后装治疗机对110例鼻咽癌患者随机分为外照射
Nasopharyngeal carcinoma is a high incidence of malignant tumors in southern provinces, radiation therapy is the main treatment for nasopharyngeal carcinoma, but after conventional radical radiotherapy there are still 13% to 30% of nasopharyngeal carcinoma primary tumor residues, in order to promote the regression of nasopharyngeal carcinoma , To reduce the possibility of relapse, and to avoid excessive excretion caused by heavy sequelae, our hospital introduced a GZP6 computer-controlled cobalt 60 after-treatment machine for 110 patients with nasopharyngeal carcinoma were randomly divided into external irradiation
