【摘要】目的总结鼻咽癌患者根治性常规放疗后长期生存情况。方法经病理证实为鼻咽癌、行连续根治性常规放疗的初治患者335例,∶1,发病中位年龄47岁(15~77岁);Ⅰ,Ⅱ,Ⅲ,Ⅳa及Ⅳ%,%,%,%%。直线加速器、低熔点铅挡、常规分割外照射,鼻咽原发灶中位剂量72 Gy,~ Gy,面颈联合野+面颈联合缩野+耳前野三阶段照射。%的患者接受顺铂+氟尿嘧啶1~2周期的诱导化疗和/或1~5周期的辅助化疗。%,中位随访时间55月(1~104月)。全组5年总生存率、无进展生存率、无复发生存率、无远处转移生存率、无进展率、%,%,%,%,%,%%;Ⅰ,Ⅱ,Ⅲ,Ⅳa及Ⅳb %,%,%,%%。发生率较高的晚期损伤依次为口干燥症、颈部纤维化、张口受限、听力缺失、龋齿与牙脱落、吞咽困难、声音改变。放射性脑病、后组脑神经损伤的独立影响因素分别为原发灶剂量(P=)、T分期(P=)。结论对于原发灶剂量大、T分期较晚者应注意防治放射性脑病。

ABSTRACT: Objective To analyze the longterm survival of patients with nasopharyngeal carcinoma who were treated with radical conventional radiotherapy in a single institute. Methods 335 consecutive patients from Nov. 1999 to Dec. 2004, who were histologically proven suffering from nasopharyngeal carcinoma and treated with radical conventional radiotherapy, were retrospectively analyzed. These patients were in a male/female ratio of ∶1. The patients' ages ranged from 19 to 78 years old (median age of 47 years). Those with StageⅠ,Ⅱ,Ⅲ and Ⅳ(the Fuzhou Staging System, 1992) were %, %, %, % and %, respectively. All patients were given radical external beam irradiation. Results The followup rate was %, with a median followup time of 55 months (1~104 months). The 5year actual overall survival rate (OS), progression free survival rate (PFS), relapsefree survival rate (RFS), distant metastasisfree survival rate (DMFS), progressionfree rate (PFR), locoregional control rate (LRCR) and distant metastasisfree rate (DMFR) were %, %, %, %, %, % and %, respectively. The 5year OS rates were %, %, %, % and % for patients with Stage Ⅰ, Ⅱ, Ⅲ, Ⅳa and Ⅳb, respectively. The injuries in advanced stage with high incidence included such radiationplications as xerostomia, fibro
