目的：探讨鼻咽癌首程放射治疗的摆位和照射技术。方法：运用60Co－γ线和8MV－Ⅹ线等对鼻咽癌行多野超分割同时放疗，照射野包括鼻咽部、颅底及颈部。结果：放疗后，396例患者随访1～5年，随访率为93．62％，总5年生存率为52．72％，且无明显后遗症发生。结论：放射治疗技术是目前鼻咽癌放射治疗中值得深入探讨的课题。 Objective: To investigate the placement and irradiation of nasopharyngeal carcinoma in the first course of radiation therapy. Methods: Multi-field radiofrequency radiation was performed on nasopharyngeal carcinoma with 60Co-γ ray and 8MV-Ⅹ ray. The radiation field included nasopharynx, skull base and neck. Results: After radiotherapy, 396 patients were followed up for 1 to 5 years, the follow-up rate was 93.62%, the overall 5-year survival rate was 52.72%, and no obvious sequelae occurred. Conclusion: Radiation therapy is currently the topic worthy of further discussion in radiotherapy of nasopharyngeal carcinoma.
