EUR J Cancer:帕尼单抗联合顺铂/吉西他滨治疗KRAS野生型胆管癌

联合化疗已显示出在胆管癌治疗方面的优势,并且通过添加生物制剂可以实现进一步的改善。研究人员在此报道称EGFR抗体帕尼单抗在KRAS野生型胆管癌治疗的效果。

晚期胆管癌患者被随机分配(21),第1天和第8天使用(A组,62例患者)或不使用帕尼单抗(B组,28例患者),同时接受顺铂(25 mg / m2)和吉西他滨联合化疗,主要终点为6个月时的无进展生存期(PFS)。次要终点包括客观缓解率(ORR),总生存率(OS)和毒性。此外,研究人员还对使用和不使用EGFR抗体的化疗结果进行了荟萃分析。

用顺铂/吉西他滨/帕尼单抗治疗的患者在6个月时的PFS率为54%,而顺铂/吉西他滨组为73% 次要终点:A组的ORR45%B组为39%,中位OS分别为12.8个月(A组)和20.1个月(B组)。根据研究结果,12项试验的荟萃分析并未显示EGFR抗体治疗组与单纯化疗组的优势。

因此,帕尼单抗联合化疗并不能改善KRAS野生型晚期胆管癌患者的ORRPFSOS
