Clin Cancer Res:不同治疗方式和基因突变对肝内胆管癌患者预后的影响

2021-05-13 MedSci原创 MedSci原创

对于淋巴结转移阳性的IHC患者,采用手术切除还是肝动脉灌注化疗的生存期没有区别,但都优于单纯系统化疗

肝内胆管癌(IHC)切除后发现淋巴结转移(LNM)会大大降低患者的生存率。对于发生LNM的IHC的最佳治疗方法尚不明确,也还不知道肿瘤突变图谱能否帮助制定治疗决策。

Jolissaint等人对于2000年至2018年期间在其医疗机构就诊的接受了肝切除术(n=237)、肝动脉灌注化疗(HAIC,n=196)或单纯系统化疗(SYS,n=140)治疗的有或无LNM的IHC患者进行了回顾性分析。通过基因组测序分析明确肿瘤基因突变是否可对有LNM的患者的预后进行分层。

有无淋巴结转移的患者采用不同方式治疗的预后

分析结果显示,在没有淋巴结转移的情况下,通过手术切除肿瘤的患者的中位总生存期最长(OS: 59.9个月,95%CI 47.2-74.31),其次是接受HAIC治疗的患者(24.9个月,95%CI 20.3-29.6),采用SYS治疗的患者的中位总生存期最短(13.7个月,95%CI 8.9-15.9;p<0.001)。

在已经发生淋巴结转移的情况下,采用手术或HAIC治疗的患者的生存期方面没有明显差异(中位OS:19.7个月, 95%CI 12.1-27.2[手术] vs 18.1个月, 95%CI 14.1-26.6[HAIC], p=0.560),但都比采用SYS治疗的患者的生存期长(11.2个月, 95%CI 14.1-26.6, p=0.024)。

有无遗传变异的患者的预后

与不携带突变(野生型)的患者相比,至少有一个高风险遗传变异(TP53突变、KRAS突变、CDKN2A/B缺失)的淋巴结转移阳性患者,无论采用哪种治疗,预后均较差(中位OS 12.1个月,95%CI 5.7-21.5,p=0.002)。

有无IDH1/2突变的患者的预后

相反,携带IDH1/2突变的淋巴结阳性患者的生存期与野生型患者无明显差异。

综上所述,对于淋巴结转移阳性的IHC患者,采用手术切除还是肝动脉灌注化疗的生存期没有区别,但都优于单纯系统化疗。高风险遗传变异的存在或可为指导治疗提供有用的预后信息。
