目的 探析化疗联合调强放疗（IMRT）治疗老年（≥65岁）局部晚期鼻咽癌的临床效果。方法 选取2018年1月—2019年1月我院诊治的90例老年局部晚期鼻咽癌患者为研究对象,使用随机数表法将此90例患者分为观察组及对照组,各45例。观察组行IMRT,对照组行化疗联合IMRT,对比2组的效果。结果 2组的治疗总有效率均为100%,组间差异不显著（P<0.05）。观察组的生活质量改善率（93.33%）高于对照组（77.78%）（P<0.05）。对照组出现3~4级白细胞减少、呕吐、黏膜炎人数明显高于观察组（P<0.05）,两者其他毒副反应比较无显著差异（P>0.05）。观察组的1年总体生存率（91.11%）及3年总体生存率（75.56%）均高于对照组（86.67%、68.89%）（P<0.05）。结论 对于老年局部晚期鼻咽癌,化疗联合IMRT相比单纯IMRT降低了远期生存率,增加了毒副反应并影响疗后生活质量的改善,不宜常规应用,单纯IMRT可能是更合适的治疗选择。

Objective To explore the clinical effect of chemotherapy combined with intensity modulated radiation therapy（IMRT）in the treatment of elderly（≥65 years old）locally advanced nasopharyngeal carcinoma．Methods The study was carried out from January 2018 to January 2019．During this period,90 elderly patients with locally advanced nasopharyngeal carcinoma who were diagnosed and treated in our hospital were selected as the research objects．The random number table method was used to divide the 90 patients into observation groups,and the control group,each with 45 cases．The observation group was treated with IMRT,and the control group was treated with chemotherapy combined with IMRT．The effects of the two groups were compared．Results The total effective rate of the two groups was 100%,and there was no significant difference between the two groups（P<0.05）．The improvement rate of quality of life in the observation group（93.33%）was higher than that in the control group（77.78%,P<0.05）．The number of grade 3-4 leukopenia,vomiting and mucositis in the control group was significantly higher than that in the observation group（P<0.05）,and there was no significant difference in other side effects between the two groups（P>0.05）．The 1-year overall survival rate（91.11%）and 3-year overall survival rate（75.56%）of the observation group were higher than those of the control group（86.67%,68.89%,P<0.05）．Conclusions For locally advanced nasopharyngeal carcinoma in the elderly,chemotherapy combined with IMRT reduces the long-term survival rate,increases the toxic and side effects and affects the improvement of the quality of life after treatment．It is not suitable for routine application,and IMRT alone may be a more appropriate treatment choice.

目的 评价调强放疗后颞颌关节损伤的鼻咽癌患者的生存情况。方法 2010年2月—2013年11月期间90例经调强放疗后出现颞颌关节损伤的鼻咽癌患者,鼻咽病灶放疗剂量70～74Gy/32～33f,转移淋巴结放疗剂量64～70Gy/32～33f,高危区预防性放疗剂量58～66Gy/32～33f,低危区预防性放疗剂量54～58Gy/32～33f,采用顺铂、奈达铂或多西他赛行同步化疗。回顾性分析患者的张口困难程度、近期疗效、无局部复发生存、无远处转移生存及总生存情况,同时评价放疗毒副反应。结果 ①颞颌关节损伤:97.8%的患者为Ⅰ级损伤,2.2%的患者为Ⅱ级损伤,无Ⅲ~Ⅳ级重度放射性损伤;②近期疗效:完全缓解67例(74.5%),部分缓解21例(23.3%),稳定1例(1.1%),进展1例(1.1%),总有效率(ORR)为97.8%(88/90),疾病控制率(DCR)为98.9%。③生存情况:中位随访时间57个月(5～84个月),5年无局部复发生存率、无远处转移生存率和总生存率分别为85.6%、71.1%和73.3%。④不良反应:3~4度不良反应有白细胞减少(发生率为24.4%)、中性粒细胞减少(发生率为21.1%)和血小板减少(发生率为1.1%)等血液学毒性以及口腔黏膜炎(发生率为43.3%)、呕吐(发生率为1.1%)和放射性皮炎(发生率为3.3%)等非血液学毒性。结论 鼻咽癌调强放疗后颞颌关节损伤以I度为主;调强放疗后出现颞颌关节损伤的鼻咽癌患者以T3~T4为主,但仍可获得较满意的局控率、较低的远处转移率和较高的总生存率,且安全性较高。
