[目的]探讨原发灶复发鼻咽癌的再分期与其预后的关系。[方法]对336例原发灶复发鼻咽癌患者的临床资料进行回顾性分析,采用UICC(2009)分期标准进行临床分期,应用Kaplan-Meier和Log-rank法计算和比较各期患者生存率。用Cox逐步回归模型进行多因素分析。[结果]全组患者1、3、5年生存率分别为85.0%、48.0%、32.0%,其中Ⅰ期、Ⅱ期、Ⅲ期和Ⅳ期的5年生存率分别为67.7%,35.0%,30.3%和19.9%,4组生存率比较差异有显著性(χ2=26.381,P=0.000)。Cox多因素分析结果显示临床分期是影响预后的因素。[结论]UICC(2009)分期可较好预测原发灶复发鼻咽癌的预后。
[Objective] To investigate the relapse of primary tumor recurrence of nasopharyngeal carcinoma and its relationship with the prognosis. [Methods] The clinical data of 336 primary NPC patients with recurrent nasopharyngeal carcinoma were retrospectively analyzed. UICC (2009) staging was used to analyze the clinical stage. The Kaplan-Meier and Log-rank methods were used to calculate and compare the survival rates . Cox regression model was used for multivariate analysis. [Results] The 1, 3, 5-year survival rates of all patients were 85.0%, 48.0% and 32.0%, respectively. The 5-year survival rates of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 67.7% and 35.0% 30.3% and 19.9%, respectively. There were significant differences in survival rates between the four groups (χ2 = 26.381, P = 0.000). Cox multivariate analysis showed that clinical stage is the prognostic factor. [Conclusion] UICC (2009) stage can predict the prognosis of primary tumor recurrence of nasopharyngeal carcinoma.
