We analysed 32 cases of nasopharyngeal carcinoma (NPC) treated with radiotherapy trying to define the role of CT scan during radiotherapy planning, as well as radiation treatment and the follow-up of the patients. CT scan was found to help 15 cases with low-parapharyngeal involvement and/or bone erosion. Persistent abnormal CT findings at 2 mo after the end of radiation treatment were related to a 30% local recurrence rate. This rate went up to 100% in case of skull-base destruction.
我们分析了32例接受放射治疗的鼻咽癌患者，试图明确CT扫描在放射治疗计划制定、放射治疗以及患者随访过程中的作用。结果发现，CT扫描有助于诊断15例存在咽旁间隙低位受累和/或骨质侵蚀的病例。放射治疗结束后2个月时CT检查结果持续异常与30%的局部复发率相关。若出现颅底破坏，该复发率则升至100%。
