局部晚期鼻腔鼻窦肿瘤放射治疗影响因素分析

目的:分析84例局部晚期鼻腔鼻窦肿瘤放射治疗的疗效和影响因素。方法:对2006-2008年我科共治疗的84例局部晚期(T3、T4期)鼻腔鼻窦肿瘤患者的临床资料进行回顾性分析。结果:1、2、3年生存率及总生存率分别为93.5%、71.3%、46.2%和82.1%。单因素分析显示,性别、放化疗、病理类型与生存率无相关性,而T分期、放疗剂量、放疗技术、手术后联合放疗与生存率相关。多因素分析显示,T3期、手术后联合放疗、放疗剂量>70 Gy、调强放疗均是影响患者生存率的独立预后因素。即肿瘤T分期相对较早(T3期),能够行手术切除,术后配合调强放疗,给予相对较高的放疗剂量(>70 Gy),患者生存率就能从中获益。IMRT组与3D-CRT组放疗后口干发生率分别为2.4%和7.1%,P=0.03。结论:放射治疗是局部晚期鼻腔鼻窦肿瘤有效的治疗手段,术后放疗能明显提高生存率。调强放疗较三维适形放疗在鼻腔鼻窦肿瘤治疗中,能明显提高靶区剂量,进而提高生存率,同时降低口干发生率,且没有Ⅲ级以上的晚期毒副反应的发生,调强放疗应被视为局部晚期鼻腔鼻窦肿瘤的标准治疗方法。

Prognostic analysis of patients with locally advanced nasal cavity and sino-nasal carcinoma treated by radiotherapy

OBJECTIVE: To evaluate the efficacy and affect factors of the patients with locally advanced nasal cavity and paranasal sinus carcinoma treated by radiotherapy.METHODS: Retrospective analysis of the 84 patients(T3,T4) with locally advanced nasal cavity and paranasal sinus carcinoma treated with radiotherapy from 2006 to 2008.RESULTS: 1-,2-,3-year survival rates and overall survival rates were 93.5%,71.3%,46.2% and 82.1%.Univariate analysis showed that gender,pathologic types,concurrent chemotherapy were not...
