Abstract Nanoliposomal irinotecan with fluorouracil and folinic acid (NFF) is a standard regimen after gemcitabine-based therapy for patients unresectable or recurrent pancreatic cancer. However, there are limited clinical data on its efficacy safety in the real-world. We therefore initiated retrospective prospective observational study (NAPOLEON-2). The results of part were reported herein. In this study, we evaluated 161 consecutive who received NFF as second-or-later-line regimen. main...

721 Background: Nanoliposomal irinotecan (NAL-IRI) and fluorouracil with folinic acid (NFF) is the standard regimen after gemcitabine-based therapy for unresectable or recurrent pancreatic cancer (urPC). However, we have almost no prospective data on its efficacy safety in real-world, so conducted this study to investigate them both retrospectively prospectively (NAPOLEON-2 study). We previously reported retrospective ASCO-GI 2023, here report final results of part. Methods: collected urPC...

762 Background: Nanoliposomal irinotecan and fluorouracil with folinic acid (NFF) is a standard regimen after gemcitabine-based chemotherapy (CTx) for unresectable or recurrent pancreatic cancer (urPC) patients. Neutropenia caused by systemic CTx has been reported to be prognostic marker in several cancers, however, the relationship between neutropenia efficacy of NFF urPC patients unknown. Therefore, we initiated prospective observational study investigate whether can real-world (NN-2401),...

Abstract There are limited absolute biomarkers for determining the prognosis before first- and second-line palliative chemotherapy in unresectable pancreatic cancer (urPC) patients. To find best prognostic inflammatory marker, we investigated relationships between overall survival (OS) six markers; C-reactive protein/albumin ratio (CAR), neutrophil–lymphocyte (NLR), nutrition index (PNI), platelet–lymphocyte (PLR), Glasgow score (GPS), (PI). We examined 255 patients who received gemcitabine...

Abstract The relationship between nanoliposomal irinotecan/fluorouracil/leucovorin (NFF) treatment outcomes and neutropenia in patients with pancreatic cancer has not been thoroughly examined. Thus, we conducted a retrospective analysis of data from who were treated NFF to investigate this relationship. Neutropenia was assessed according the Common Terminology Criteria for Adverse Events across three cutoffs: A (grade 0 versus grade 1–4), B (grades 0–1 2–4), C 0–2 3–4). primary endpoint...

Background: Relationships between cancer onset, progression, and inflammation have been reported; yet, the significance of inflammatory markers before after treatment with nanoliposomal irinotecan fluorouracil folic acid (NFF) is unclear. Objectives: We aimed to (1) investigate whether worsening associated disease progression it can be used as a biomarker by comparing NFF (2) verify which superior biomarker. Design: This was preplanned analysis retrospective cohort NAPOLEON-2 study,...

Abstract Background No reliable nomogram has been developed until date for predicting the survival in patients with unresectable pancreatic cancer undergoing treatment gemcitabine plus nab–paclitaxel (GnP) or FOLFIRINOX. Methods This analysis was conducted using clinical data of Japanese GnP FOLFIRINOX obtained from a multicenter study (NAPOLEON study). A Cox proportional hazards model used to identify independent prognostic factors. predict 6–, 12–, and 18–month probabilities generated,...

Abstract First-line chemotherapy for patients with metastatic pancreatic cancer (MPC) includes gemcitabine plus nab-paclitaxel (GnP) and FOLFIRINOX (FFX). However, the efficacy of second-line role combination in clinical practice is still unknown. Data was gathered from 14 hospitals Kyushu area Japan December 2013 to March 2017. The median overall survival (mOS) treatment contrasted between who received (CT group) those best supportive care (BSC group). Furthermore, mOS compared mono CT...

Abstract This study aimed to compare second-line treatment outcomes for patients with unresectable pancreatic cancer previously treated gemcitabine plus nab–paclitaxel (GnP) therapy. We conducted an integrated analysis of two retrospective studies included 318 receiving nanoliposomal irinotecan + 5-fluorouracil/folinic acid (NFF) (n = 102), S-1 57), or FOLFIRINOX 14) as treatment. Median overall survival (OS) in the NFF group was 9.08 months, significantly better than (4.90 P 0.002). had a...

Recent advances in chemotherapy have made significant progress conversion surgery (CS) for unresectable pancreatic cancer (uPC). However, the success rate and efficacy of CS not been fully demonstrated patients with uPC treated FOLFIRINOX (FFX) or gemcitabine plus nab-paclitaxel (GnP).We retrospectively reviewed records 318 who received FFX GnP as first-line chemotherapy. The group, defined undergoing complete resection after chemotherapy, was analyzed, compared non-CS group; then,...

Patients Methods: Forty-four patients with rPC 211 de novo metastatic (mPC) who received GnP or as first-line chemotherapy were retrospectively analyzed. Results: On crude analysis, median overall survival (OS) significantly longer in group than mPC (14.0 vs. 10.6 months, respectively; p=0.02). However,...

Introduction: Fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) improve overall survival (OS) progression-free (PFS) in patients with pancreatic cancer, compared gemcitabine (GEM). However, whether PFS is a surrogate marker of OS cancer chemotherapy focusing on FOLFIRINOX or GEM plus nab-paclitaxel remains unknown. We aimed to verify can be prognosis prediction.
