Abstract:
720 Background: Borderline resectable pancreatic cancer (BRPC) and locally advanced unresectable pancreatic cancer (LAUPC) are heterogeneous disease entity with various prognosis. Based on the phase III PRODIGE trial, (m)FOLFIRINOX has been widely used for the management of patients with BRPC and LAUPC. Considering the lack of large phase 3 trial of (m)FOLFIRINOX for BRPC and LAUPC, real-life evidences of (m)FOLFIRINOX are needed. Methods: In this retrospective analysis, 199 patients who received at least one dose of (m)FOLFIRINOX between February 2013 and January 2017 were included. Endpoints of this study were objective response rates (ORR), surgical resection rate, progression-free survival (PFS) and overall survival (OS). Results: Median age was 60 years (range, 33-79) and 62.3% of patients were male. Pancreas head (n=112, 56.3%) was the most common primary tumor site, followed by body (n=42, 21.1%) and multifocal (n=34, 17.1%). By an independent radiology review, patients were classified to BRPC (n=75, 37.7%) and LAUPC (n=124, 62.3%). With median 40.3 months (95% CI, 36.7-43.8) of follow-up duration in surviving patients, ORR was 26.6% (n=53), median PFS and OS were 10.6 months (95% CI, 9.5-11.7) and 17.1 months (95% CI, 13.2-20.9), respectively. There was no difference in PFS and OS between BRPC and LAUPC (median PFS, 11.1 months [95% CI, 8.8-13.5] vs. 10.1 months [95% CI, 8.4-11.8], p=0.47); (median OS, 18.4 months [95% CI, 16.1-20.8] vs. 17.1 months [95% CI, 13.2-20.9], p=0.50). Curative-intent surgery (R0 and R1) was done in 63 patients (33.2%, 49 for R0 and 14 for R1) after treatment with (m)FOLFIRINOX. Resection rates were 58.2% in BRPC patients and 19.4% in LAUPC patients (p 〈 0.001). In patients who underwent curative-intent surgery, median disease-free survival since surgery was 10.4 months (95% CI, 8.3-12.5 ) and there was no difference according to the baseline disease extent (BRPC vs. LAUPC): 10.0 months (95% CI, 7.5-12.5) vs. 12.0 months (95% CI, 3.7-20.3), p=0.37. Conclusions: (m)FOLFIRINOX is effective therapy for BRPC and LAUPC patients. Significant proportion of patients could receive curative-intent surgery.
