Efficacy and Feasibility of Adjuvant Gemcitabine Plus Cisplatin Chemotherapy After Major Hepatectomy for Biliary Tract Cancer

Background/Aim: The efficacy and feasibility of gemcitabine plus cisplatin (GC) chemotherapy in an adjuvant setting is unclear in patients with biliary tract cancer (BTC) undergoing major hepatectomy. Patients and Methods: Patients with BTC who underwent major hepatectomy between 2008 and 2018 were included. Patients who received adjuvant chemotherapy (AC) were then divided into two groups: a GC group and a gemcitabine (GEM) alone group. AC-related factors and patient outcomes were investigated. Results: Fifty (GC: 28, GEM: 22) patients received AC, and 33 patients did not. No difference in completion rate, relative dose intensity, or adverse events was seen between the two AC groups. Multivariate analysis revealed that AC with GC was an independent predictor of improved survival and reduction of early recurrence. Conclusion: AC with GC is tolerable and associated with better outcomes in patients with BTC who have undergone major hepatectomy.
