| 目的 探讨鼻咽癌常规放疗后放射性后组颅神经损伤(RILCN)的危险因素,以指导鼻咽癌放疗计划的制定。方法 采用1∶2配对的病例对照研究,回顾性分析100对接受根治性放射治疗的鼻咽癌患者,应用条件Logistic回归模型分析可能影响RILCN形成的因素。结果 选入回归方程的因素有吸烟、照射方法、上颈部照射剂量、颈部纤维化和颈部皮肤急性放射毒性,其危险度比分别为4.594、2.629、1.072、4.141和2.531。结论 吸烟、照射方法、上颈部照射剂量、颈部纤维化和颈部皮肤急性放射毒性是RILCN发生的危险因素。建议停用耳前野加全颈切线野的照射方式。 |

| Objective To study the risk factors of radiation-induced lower cranial neuropathy (RILCN) after conventional radiotherapy in patients with nasopharyngeal carcinoma, and to improve the radiotherapeutic planning. Methods A hundred cases received radical radiotherapy of nasopharyngeal carcinoma and 200 individual matched controls on sex, age and time to start the radiotherapy were studied. Conditional logistic regression model was used to analyze 13 risk factors related to development of RILCN. Results Conditional logistic regression analysis revealed that cigarette smoking, irradiation scheme, radiation dose to the superior neck, neck fibrosis and acute radiation-related dermatitis of neck were risk factors of RILCN, their relative risks were 4.594, 2.629, 1.072, 4.141 and 2.531, respectively. Among three external irradiation schemes, it is found that pre-auricular portal plus whole neck tangential portal irradiation had the highest risk of RILCN. Conclusions The study suggested that the irradiation scheme of pre-auricular portal plus whole neck tangential portal should be no longer used. |
