背景和目的
为了改善胆管癌的预后,有很多潜在的生物标志物被研究者们研究,本项研究旨在探究哪些生物标志物可以预测术后辅助化疗的效果。

方法
本项研究回顾性分析了170例手术切除的胆管癌患者的临床资料,26例接受吉西他滨辅助化疗(GEM组),36例接受S-1辅助化疗(S-1组),103例未接受辅助化疗(NC组)。并选择健康对照组(NC组)36名患者。进行乳清酸磷酸核糖转移酶(OPRT)和人平衡核苷转运蛋白1(hENT1)的免疫组织化学以确定它们的表达与无病存活(DFS)之间的相关性。

结果
在整个研究中研究人员未观察到辅助化学疗法对DFS的显着改善。然而,在高OPRT表达患者中,5年时GEM,S-1和NC组的DFS分别为28.8%,53.8%和25.5%。S-1组的DFS明显长于NC组(P=0.034)。另一方面,在低OPRT表达患者中未观察到DFS的显着差异。hENT1表达显示没有预测价值。高OPRT表达患者的多变量分析表明,S-1辅助化疗可以减少肿瘤复发(HR,0.303; P= 0.013)。

结论
具有高OPRT表达的胆管癌患者将受益于术后辅助S-1治疗,增加DFS时间。评估OPRT表达可能有助于优化胆管癌的辅助化疗。
