目的对不同鼻咽癌调强放疗剂量分割模式的近期疗效和不良反应进行探究。方法将我院2011年1月~2013年1月收治的74例鼻咽癌患者改变以往剂量分割模式,均给予螺旋断层技术进行治疗。结果 30例CR,39例PR,5例SD,0例PD;患者出现骨髓抑制现象,其中,3例患者出现4度骨髓抑制,对其停止放化疗以及对症处理后,症状缓解,继续给予放疗。结论治疗鼻咽癌患者通过改变调强放疗剂量分割模式,具有较好近期疗效,且能减少不良反应。
Objective To explore the short-term curative effect and adverse reactions of different dose division mode of intensity modulated radiotherapy in nasopharyngeal carcinoma. Methods A total of 74 patients with nasopharyngeal carcinoma who were treated in our hospital from January 2011 to January 2013 were retrospectively divided into two groups, all of which were treated by spiral CT. Results 30 cases of CR, 39 cases of PR, 5 cases of SD, 0 cases of PD; patients with myelosuppression, including 3 patients with 4 degrees bone marrow suppression, to stop radiotherapy and chemotherapy and symptomatic treatment, the symptoms were relieved, continue to give radiotherapy . Conclusion The treatment of nasopharyngeal carcinoma by changing the dose-division mode of intensity-modulated radiotherapy has a good short-term curative effect and can reduce adverse reactions.
