采用改良的FOLFIRINOX方案进行辅助治疗可相比吉西他滨显著延长已手术切除的胰腺导管腺癌患者的生存期

PRODIGE 24试验随访3年时的结果显示,已切除的胰腺导管腺癌患者可从改良的FOLFIRINOX方案辅助治疗中获益,但目前尚无充分的证据数据。

本文报告了该试验随访5年的结果,同时探索了影响总生存期的预后因素。

这是一项国际性、开放标签的3期试验,招募了18-79岁、组织学明确诊断的胰腺导管腺癌患者,入组患者在随机分组前3-12周内已进行了完全切除(R0/R1)。受试患者(1:1)随机接受改良的FOLFIRINOX方案或吉西他滨辅助治疗24周。主要终点是无病生存期。次要终点包括总生存期、无转移生存期和癌症特异性生存率。


两组患者的生存预后分析

共招募了493位患者,其中216位(43.8%)是女性,平均62.0岁。中位随访了69.7个月,共观察到367例无病生存事件。改良FOLFIRINOX组和吉西他滨组的中位无病生存期分别是21.4个月和12.8个月(HR 0.68, p<0.001),五年无病生存率分别是26.1%和19.0%;中位总生存期分别是53.5个月和35.5个月(HR 0.68,p=0.001),五年总生存率分别是43.2%和31.4%;中位无转移生存期分别是29.4个月和17.7个月(HR 0.64,p<0.001);中位癌症特异性生存期分别是54.7个月和36.3个月(HR 0.65, p<0.001)。

多变量分析显示,改良的FOLFIRINOX、年龄、肿瘤分级、肿瘤分期和大体积中心都是总体生存的显著有利的预后因素。较短的复发延迟是不利的预后因素。

总之,该研究的最终五年随访结果显示,采用改良的FOLFIRINOX方案进行辅助治疗可相比吉西他滨显著延长已手术切除的胰腺导管腺癌患者的生存期。
