摘要
[目的]观察不同放射治疗方案对T3~4期鼻咽癌患者耳部的影响.[方法]回顾性分析本院就诊的102例T3~4期鼻咽癌患者的临床资料,适形调强放疗(IMRT)组56例,三维适形放疗(3D-CRT)组46例,比较两组疗效、放射性中耳炎发生率及听力受损情况.[结果]两组患者近期局部控制率差异无统计学意义(P>0.05),3D-CRT组的中耳及耳蜗照射剂量明显高于IMRT组(P<0.05),两组放疗后6个月中耳炎发生率及听力损伤发生率比较,差异无统计学意义(P>0.05).[结论]对T3~4期鼻咽癌患者放疗后耳功能的保护,IMRT比3D-CRT技术具有剂量学优势,但未见临床优势,3D-CRT对经济条件较差的患者仍是性价比较高的选择.
[Objective]To observe the impact of different radiation therapy methods on ears of patients with T3 and T4 stage nasopharyngeal carcinoma.[Methods] Clinical data of 102 patients with T3 and T4 stage nasopharyngeal carcinoma in our hospital were analyzed retrospectively.All patients were divided into intensity-modulated radiation therapy (IMRT) group (n =56) and 3-dimensional conformal radiation therapy (3D-CRT) group(n =46).The efficacy,the incidence of radioactive otitis media and hearing impairment were compared between two groups.[Results]There was no significant difference in short-term local tumor control rate between two groups(P >0.05).Exposure dose of middle ear and cochlea in 3D-CRT group was significantly higher than that in IMRT group(P <0.05).There was no significant difference in the incidence of otitis media and hearing impairment between two groups at 6 months after radiotherapy(P >0.05).[Conclusion] For the protection of ear function in patients with T3 and T4 stage nasopharyngeal carcinoma after radiotherapy,IMRT is superior to 3D-CRT in the aspect of dosage,but not in clinical efficacy.The 3D-CRT is still a top priority for patients with poor economic condition.
