摘要:

目的 比较Ⅱ期鼻咽癌同步放化疗与单纯放疗的疗效。 方法 收集2007年6月至2014年4月在我院接受同步放化疗的Ⅱ期鼻咽癌患者56例为同步组,同期行单纯放疗的Ⅱ期鼻咽癌患者51例为单放组。对两组患者生存状况进行回顾性分析,比较两组总生存率、无远处转移生存率、无局部区域复发生存率及无失败生存率。 结果 同步组与单放组相比,各种生存率差异均无统计学意义(P均>0.05),两组总生存率、无远处转移生存率、无局部区域复发生存率及无失败生存率的风险比(HR)分别为1.15 (95%CI=0.21~6.36)、1.10 (95%CI=0.26~4.73)、1.16 (95%CI=0.33~6.89)、1.38 (95%CI=0.36~5.25)。多因素分析提示年龄是无局部区域复发生存率的预后因素(P=0.030),年龄越大生存率越低。 结论 与单纯放疗相比,同步放化疗未能改善Ⅱ期鼻咽癌患者的预后,调强放疗联合同步化疗对Ⅱ期鼻咽癌预后的影响还需进一步研究。

Abstract:

Objective This study aimed to compare survival in patients with stage II nasopharyngeal carcinoma(NPC) treated by concurrent chemoradiotherapy(CCRT) or radiotherapy(RT) alone. Methods Data were retrospectively analyzed for patients with stage Ⅱ NPC treated between June 2007 and April 2014 with CCRT(n=56) or RT alone (n=51). The two patient groups were matched based on prognostic factors. The primary endpoint was overall survival (OS),and secondary endpoints were distant metastasis-free survival (DMFS),locoregional relapse-free survival (LRRFS),and failure-free survival (FFS). Results The two groups showed similar primary and secondary outcomes:hazard ratios (HR) of the CCRT group relative to the RT group were 1.15 (95%CI 0.21-6.36) for OS,1.10(95%CI 0.26-4.73) for DMFS,1.16(95%CI 0.33-6.89) for LRRFS,and 1.38 (95%CI 0.36-5.25) for FFS. Multivariate analyses indicated that older age predicted lower LRRFS. Conclusion CCRT does not appear to improve prognosis of patients with stage Ⅱ NPC over conventional RT. Future studies should examine the efficacy of combining intensity modulated radiotherapy(IMRT) with CCRT.
