Abstract

Purpose: Given the promising activity and tolerability of FOLFIRINOX as a second-line treatment for advanced biliary tract cancer (BTC), it can be an attractive first-line treatment option as well. Materials and Methods: This is a single-arm, open-label, multicenter phase II study to evaluate the safety and efficacy of FOLFIRINOX as a first-line treatment for patients with advanced BTC. Primary endpoint was progression-free survival (PFS), and the secondary endpoints included overall survival (OS), tumor response and safety. This study defined primary endpoint might be met when the lower limit value of 80% confidence interval [CI] of the median PFS ≥ 6.0 months. Results: Between June 2016 and March 2020, 35 BTC patients (21 intrahepatic, 10 extrahepatic, 2 gallbladder, 2 ampulla) including 26 unresectable and 9 recurrent disease were enrolled. After a median follow-up of 13.9 months, the median PFS and OS were 7.4 (80% CI, 5.5-7.5) and 14.7 (80% CI, 11.8-15.7) months, respectively. Complete response was achieved in 1 (2.9%) and partial response in 10 (28.6%), giving an objective response rate of 31.4% and disease control rate of 74.3%. Major grade 3-4 adverse events included neutropenia (54.3%), leukopenia (34.4%), febrile neutropenia (17.1%), thrombocytopenia (8.6%), cholangitis (8.6%), anemia, nausea, diarrhea, and peripheral sensory neuropathy (2.9% each). Conclusion:.FOLFIRINOX was well tolerable in patients with advanced BTC, however, this study did not meet the primary endpoint to conduct a phase III trial. Thus, further explorations are required to find a subset of patients and/or certain clinical scenario which might be beneficial from FOLFIRINOX.
