由于后装技术和放射源的改进发展,间质插植放疗近年有所增加,这一技术的关键是精确放置放射源。 对鼻咽癌局部复发和残留肿瘤,我们所用的方法是将放射源插入肿瘤及其周围,使肿瘤及其周围组织达到较好剂量分布。选择病人的标准为:1.无骨质破坏; 2.无广泛咽侧壁病灶;3.无鼻中隔累及;4.无咽鼓管周围累及;5.张口必须在2cm以
Due to the improved development of post-installation technology and radioactive sources, interstitial implanted radiotherapy has increased in recent years. The key to this technology is the precise placement of radioactive sources. For local recurrence and residual tumors of nasopharyngeal carcinoma, the method we use is to insert a radioactive source into the tumor and its surroundings so that the tumor and its surrounding tissues reach a better dose distribution. The criteria for patient selection were: 1. No bone destruction; 2. No extensive pharyngeal wall lesions; 3. No nasal septal involvement; 4. No involvement around the eustachian tube; 5. Opening mouth must be at 2 cm
