Background
Gemcitabine plus cisplatin is regarded as the standard first-line therapy for patients with advanced biliary tract cancer (BTC); however, no standard chemotherapy has yet been recommended after treatment failure. Modified FOLFIRINOX (mFOLFIRINOX) appears to be a better-tolerated regimen, which leads to improved survival in metastatic pancreatic cancer that has histological and molecular similarities with BTC. We assessed the efficacy and safety of mFOLFIRINOX as salvage therapy in advanced BTC patients who were refractory to previous chemotherapy.
Methods
A total of 15 consecutive patients with documented unresectable locally advanced or metastatic BCT who received the mFOLFIRINOX regimen were included in the study. Patients were intravenously administrated with oxaliplatin (65 mg/m
2
), leucovorin (400 mg/m
2
), irinotecan (150 mg/m
2
), and continuous infusion of fluorouracil (2400 mg/m
2
) over 46 h. The objective response rates (ORR), disease control rates (DCR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were recorded.
Results
At least three cycles of mFOLFIRINOX regimen were delivered to 15 patients with a median number of 6.0 cycles (IQR 5.5–11.0). The median duration of treatment was 3.8 months (IQR 2.9–8.5). Four patients (26.7%) achieved an ORR, and 12 patients (80.0%) had a DCR. The median PFS and OS were 6.7 months (95%CI 2.3–11.1) and 13.2 months (95%CI 7.3–19.1), respectively. Five patients (33.3%) had treatment-related grade 3/4 AEs. The most common grade 3/4 AE was neutropenia (
n
= 3, 20.0%), while there was no occurrence of febrile neutropenia.
Conclusion
Treatment with mFOLFIRINOX has promising efficacy and favorable tolerance as salvage therapy in patients with refractory advanced BCT. |
