目的 研究鼻咽癌病人放射治疗前后记忆力的变化,探讨用记忆商作为放射治疗中早期发现中枢神经系统损害的指标的可能性。方法 对21例首发并且只接受~(60)Co放射治疗的鼻咽癌病人在治疗前后分别进行记忆商测定。结果 21例病人放射治疗后的量表分和记忆商较治疗前有明显下降,记忆测验的各分项量表分除指向记忆在治疗前后无差异外,其余联想学习、图象自由回忆,无意义图形再认和人像特点回忆等四项在治疗后均较治疗前有明显下降。结论 鼻咽癌病人在接受放射治疗后记忆商较放射治疗前有明显下降,记忆商作为鼻咽癌放射治疗中中枢神经系统受损害的一个观察指标是有其可行性的。
Objective To study the changes of memory in patients with nasopharyngeal carcinoma before and after radiotherapy and to explore the possibility of using memory as an indicator of early detection of central nervous system damage in radiotherapy. Methods Twenty-one nasopharyngeal carcinoma patients who were treated with ~ (60) Co radiotherapy and received radiotherapy were evaluated before and after treatment. Results 21 patients after radiotherapy score points and memory business significantly decreased compared with before treatment, memory test sub-item scale points to the memory before and after treatment, no difference, the other association learning, image free recall, no The significance of graphics recognition and memory characteristics of the four recalled after treatment were significantly lower than before treatment. Conclusions Patients with nasopharyngeal carcinoma after radiotherapy have a significant decrease in their memory compared with those before radiotherapy. The memory tracer, as an observation target of CNS injury in radiotherapy of nasopharyngeal carcinoma, is feasible.
