A multicenter randomized phase II trial published in BMC Cancer revealed that nab-paclitaxel combined with cisplatin outperforms gemcitabine plus cisplatin as chemotherapy in patients with advanced biliary tract cancer. The combination demonstrated improved efficacy and manageable safety profiles, suggesting a promising new standard for ABTC treatment. These findings could influence clinical practice guidelines and warrant larger confirmatory trials to establish long-term outcomes and broader applicability.
