Abstract Aim: This retrospective study investigated the efficacy and safety of nano-liposomal irinotecan (nal-IRI) plus 5-fluorouracil/l-leucovorin (5-FU/l-LV) treatment in the second-line or later setting for advanced pancreatic cancer under real-world conditions.Methods: Between June 2020 and September 2021, a total of 44 patients with unresectable advanced pancreatic cancer treated with nal-IRI + 5-FU/l-LV in our affiliated hospitals were included. The prognosis, predictive factors (including systemic inflammation-based prognostic indicators), and adverse events were investigated.Results: The median age was 68 (interquartile range [IQR] 62-73) years old, and 22 patients (50.0%) were male. Concerning tumor factors, 9 patients (20.5%) had local advanced disease, and 35 patients (79.5%) had metastases. Twenty-five of the 44 patients were receiving second-line treatment, and 19 were receiving third-line or later treatment. The median overall survival (OS) and progression free survival (PFS) were 9.0 (range, 0.7-15.4) months and 4.4 (range, 0.6-15.4) months, respectively. The overall response rate (ORR) was 5.3%. The disease control rate (DCR) was 44.7%. Patients with a neutrophil-to-lymphocyte ratio (NLR) of >2.7 had a significant risk of a poor OS (HR=0.275, P=0.017). Adverse events were manageable, although gastrointestinal symptoms and neutropenia were observed. The most common grade ≥3 adverse event was neutropenia, which was reported in 20% of patients.Conclusions: Nal-IRI + 5-FU/l-LV therapy was considered to be a useful regimen as second-line or later treatment for unresectable advanced pancreatic cancer, even in clinical practice.

Approximately 80% of pancreatic cancer is diagnosed at an advanced stage, due to lack of or vague symptoms when the cancer is still localized, leading to a high mortality rate. Known risk factors for developing pancreatic cancer are family history, obesity, type 2 diabetes, and alcohol and tobacco use. There has been a remarkable development in diagnosis modalities and molecular testing, but early detection is still infrequent. The majority of clinical trials have not shown significant efficacy in pancreatic cancer, and treatment strategy remains limited. Additional prognostic factors should be highlighted to obtain appropriate treatment options, including precision medicine, and improve survival outcomes. After the PRODIGE study in 2011 and the MPAC trial in 2013, a new drug (liposomal irinotecan; Onivyde ®) appeared in the strategy, especially after failure of gemcitabine-based treatment. In 2016, the NAPOLI-1 trial showed evidence of the efficacy of the liposomal irinotecan combination (liposomal irinotecan +5-fluorouracile + folinic acid); now, it is considered the standard treatment for relapsing patients. Since NAPOLI-1, real-world data have provided similar results. Herein, we report the story of a 61-year-old woman who was treated with liposomal irinotecan combination (nal-IRI/5-FU/LV) for 8 months with good surgical response, but treatment was discontinued due to economic burden. After the start of treatment (or 1? cycle of liposomal irinotecan treatment), the patient was in a better condition. The liver metastases had disappeared. The combination with liposomal irinotecan was re-administered with patient’s approval. Upon rechallenge with the liposomal irinotecan combination, she showed a partial response, and the treatment was given for 7 months. In this report, we tried to identify the prognostic factors leading to the efficacy of the liposomal irinotecan combination.

Abstract Background According to current guidelines, treatment of patients with hepatic oligometastasis in pancreatic cancer is not reflected and systemic chemotherapy is recommended in those patients. Retrospective data suggest beneficial outcomes in patients with hepatic oligometastasis, though prospective data from clinical trials addressing this particular patient group is not available. Methods In this single arm, phase-2 trial, survival data from patients receiving neoadjuvant chemotherapy followed by R0/R1 resection will be compared to historic data from patients with oligometastatic adenocarcinoma of the pancreas. The clinical trial will focus on a well-defined patient collective with metastatic load limited to the liver as target organ with a maximum of five metastases. The combination of liposomal irinotecan (nal-IRI), oxaliplatin (OX) and 5-fluouracil (5-FU)/folinic acid (FA) (nal-IRI + OX+ 5-FU/FA, NAPOX) was chosen as neoadjuvant chemotherapy; the choice was based on an ongoing clinical study in which NAPOX appeared manageable, with promising anti-tumor activity in first-line treatment of patients with metastatic pancreatic adenocarcinoma. In total 150 patients will be enrolled for this trial with an aim of 55 patients receiving a complete macroscopic synchronous tumor and metastatic resection. Discussion This is the first clinical study to prospectively evaluate the value of multimodality therapy concepts in oligometastatic pancreatic cancer. Trial registration numbers EudraCT 2019–002734-37; NCT04617457.

297 Background: There is limited research evaluating the share of patients (pts) with metastatic pancreatic cancer (m-PANC) treated according to NCCN guidelines. Methods: We identified pts with m-PANC using ICD-10 diagnosis codes in the 2016-2019 Medicare Parts A/B/D 100% Research Identifiable Files. Study pts had 2+ claims with a pancreatic cancer diagnosis and Medicare FFS coverage for 6 months pre- and 3 months post-metastatic disease diagnosis. A line of therapy (LOT) was assigned based on the order and number of therapies used. Pts with one, two, or three LOTs were defined as treated according to NCCN Category 1 guidelines if, in each LOT, pts used one of the following regimens: FOLFIRINOX (FFX), gemcitabine/nab-paclitaxel (gem/nab), gemcitabine + erlotinib, gemcitabine monotherapy, or 5-FU + leucovorin + liposomal irinotecan. Multi-drug LOTs were excluded from the analysis. Results: We identified 31,782 pts with m-PANC. 21,304 received one LOT, 7,352 received two LOTs, and 3,126 received three LOTs between 2016 and 2019. Among pts who received one or two LOTs, a higher portion were treated according to NCCN Category 1 guidelines in 2019 (72% and 43%, respectively) than in 2016 (64% and 33%, respectively). Among pts who received three LOTs, a higher portion were treated according to NCCN Category 1 guidelines in 2019 (17%) than in 2017 (12%); too few pts were treated in 2016 to make a comparison. From 2016 to 2019, FFX had the largest increase in share of pts receiving only one NCCN Category 1 LOT (11% to 27%) and gem-mono had the largest decrease (30% to 17%). Among pts receiving two NCCN Category 1 LOTs, gem/nab to liposomal irinotecan sequences had the largest increase in share of pts (18% to 32%) and gem/nab to FFX had the largest decrease (17% to 10%). Among pts receiving three NCCN Category 1 LOTs, patient share for FFX to gem/nab to Liposomal irinotecan was 35% in 2019, while gem/nab to FFX to Liposomal was 8%; pt counts in earlier years were too small to calculate patient share. Conclusions: The use of NCCN Category 1 therapies increased consistently from 2016 to 2019 among pts that received one, two, and three lines of therapy. FFX drove increases in NCCN Category 1 utilization among patients receiving one line of therapy, and gem/nab to liposomal irinotecan sequences were the primary drivers of the increase among patients receiving two lines of therapy. FFX to gem/nab to liposomal irinotecan was the primary driver of increase among patients receiving three lines of therapy.
