Biliary tract cancers(BTCs)refer to invasive adenocarcinomas arising from the bile duct(intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma)and gallbladder(gallbladder cancer).Patients with BTCs typically present at an advanced stage due to a lack of early detection methods and non-specific symptoms;systemic chemotherapy.is the cornerstone of treatment for these advanced *** plus cisplatin(GC)has been the standard treatment since the pivotal ABC-02 randomized phase 3 trial conducted in 2010(1).Moving beyond the era of GC,several triplet combination regimens have been proposed in recent years(Table 1).The combination of nab-paclitaxel(nab-P)and GC showed promising survival outcomes in a phase 2 trial(2),although it eventually failed to meet the primary endpoint of overall survival(OS)in a randomized phase 3 trial(3).Around the same time,TOPAZ-1(5)demonstrated that the programmed death ligand 1(PD-L1)inhibitor durvalumab combined with GC significantly improved the median OS[11.5 vs.12.8 months;hazard ratio(HR),0.80;95%confidence interval(CI):0.66–0.97;P=0.021]and median progression-free survival(PFS)(5.7 vs.7.2 months;HR,0.75;95%CI:0.63–0.89;P=0.001),with an objective response rate(ORR)of 26.7%.Moreover,KEYNOTE-966(6)found that the addition of programmed death-1(PD-1)inhibitor pembrolizumab also improved median OS(10.9 vs.12.7 months;HR,0.83;95%CI:0.72–0.95;P=0.0034),whereas the median PFS only showed numerical improvements(5.6 vs.6.5 months;HR,0.86;95%CI:0.75–1.00;P=0.023),with an ORR of 29%.Consequently,the combination of PD-1/PD-L1 inhibitors and GC has become the new standard of care for first-line treatment of patients with BTCs,establishing the new era of triplet combinations.
