目的 观察调强放疗(IMRT)初治鼻咽癌的临床疗效及不良反应,并分析影响预后的因素.方法 2006-2008年,6个治疗中心共300例经病理活检确诊为鼻咽癌的初治患者接受全程IMRT.UICC/AJCC 2002分期Ⅰ、Ⅱ、Ⅲ、Ⅳa+b期分别为6、45、141、108例.放疗处方剂量鼻咽原发灶计划把体积为70 ~ 74 Gy,颈部转移淋巴结计划把体积为68 ~70 Gy,计划靶体积-1为60 ~ 64 Gy,计划靶体积-2为50~ 54 Gy,均分30次6周完成.Ⅲ~Ⅳa+b期患者接受了以铂类为基础化疗.Cox法多因素预后分析.结果 随访率为99.7%.4年局部控制率、区域控制率、无远处转移率、无瘤生存率及总生存率分别为94.0%、95.5%、87.4%、80.8%及86.1%.急性1、2、3级放射性黏膜炎分别占18.0% 、48.7%、33.3%,晚期0、1、2级口干分别占12.0%、75.7% 、12.3%.18、15、42例出现局部、颈部淋巴结复发、远处转移.多因素分析显示N分期影响总生存率(x2=5.17,P=0.023)、无远处转移率(x2 =6.91,P=0.009)、无瘤生存率(x2=8.15,P=0.004).结论 IMRT可提高初治鼻咽癌患者临床疗效,不良反应可耐受,治疗失败最主要原因为远处转移,N分期是影响预后的主要因素.

Objective To evaluate the treatment efficacy,toxicities and prognostic factors of nasopharyngeal carcinoma ( NPC ) treated with intensity modulated radiation oncology ( IMRT ).Methods Between January 2006 and August 2008,300 patients with pathologically diagnosed NPC from 6 center received IMRT.The number of patients with stage Ⅰ,Ⅱ,Ⅲ and Ⅳa+b disease (UICC/AJCC 2002 staging system) were 6,45,141 and 108,respectively.The prescription doses were as follows:70-74 Gy/30f toplanning target volume of primary nasopharynx tumor ( PTVRλ),68-70 Gy/30f to planning target volume of positive lymphnode (ptvnd),60-64 Gy/30f to higher risk region (PTV1),50-54 Gy/30f to lower risk region (PTV2).Patients with stage Ⅲ and Ⅳa+b disease also received cisplatin-based chemotherapy.Cox method was used for Multivariate analysis.Results The follow-up rate was 99.7%.The 4-year rate of local control,regional control,metastasis-free survival (DMFS),disease-free survival (DFS) and overall survival (OS) was 94.0%,95.5%,87.4%,80.8%,86.1%,respectively.Mucositis was the most severe acute toxicity,with 18.0% grade 1,48.7% grade 2,33.3% grade 3.No patient suffered from grade 4mucositis.Xerostomia was the most common late toxicity,with 12.0% grade 0,75.7% grade 1,12.3%grade 2.No grade 3-4 xerostomia was observed.There were 18,15 and 42 patients failed in local,regional and distant metastasis,respectively.Multivariate analysis showed that N stage was the only prognostic factor for OS (x2 =5.17,P=0.023),DMFS (x2 =6.91,P=0.009) and DFS (x2 =8.15,P=0.004) in these patients.Conclusions IMRT can improve the treatment efficacy of NPC.The acute and late toxicities were tolerated.Distant metastasis becomes the main treatment failure.N stage is a significant prognostic factors.
