Article Abstract
Background: It remains unclear whether there is a difference in overall survival (OS) benefit between (m)FOLFIRINOX and gemcitabine-nab-paclitaxel as preoperative regimens for localised pancreatic adenocarcinoma. This study aimed to investigate the outcome of patients with resected localised pancreatic adenocarcinoma following (m)FOLFIRINOX versus gemcitabine-nab-paclitaxel.
Methods: International multicentre retrospective study (16 centres, 8 countries, 3 continents), including consecutive patients after pancreatic resection for localised pancreatic adenocarcinoma following 2-6 months preoperative (m)FOLFIRINOX or gemcitabine-nab-paclitaxel (2010-2018). Primary endpoint was OS from start of preoperative chemotherapy. Cox regression analysis was performed to investigate the association of the preoperative chemotherapy regimen with OS, adjusted for confounders at diagnosis.
Results: Overall, 935 patients were included after resection of localised pancreatic adenocarcinoma following preoperative (m)FOLFIRINOX (65%) or gemcitabine-nab-paclitaxel (35%). Preoperative chemotherapy regimen (m)FOLFIRINOX was not associated with OS (HR = 0.83 [95% CI 0.64-1.08]), compared to gemcitabine-nab-paclitaxel. Interaction analysis showed stronger effect of (m)FOLFIRINOX in patients with a lower (i.e., non-elevated/marginally elevated) serum CA19-9 at diagnosis (p = 0.032).
Conclusion: This international study found no OS benefit of preoperative (m)FOLFIRINOX in patients with resected localised pancreatic adenocarcinoma compared to gemcitabine-nab-paclitaxel.

Perineural invasion (PNI) is a common pathological characteristic of pancreatic ductal adenocarcinoma (PDAC), closely linked to postoperative recurrence, metastasis, and unfavorable prognosis. Nevertheless, the precise mechanisms that govern PNI in PDAC remain poorly elucidated. Here, group-specific component protein (GC) is identified as one of the most significantly upregulated genes related to PNI, primarily derived from malignant ductal cells compared to other cell types.

Duodenal perforation is a rare but harmful complication of endoscopic retrograde cholangiopancreatography (ERCP). Early diagnosis and appropriate management are critical to reduce morbidity and mortality. Four patients, aged 36 to 56 years, underwent ERCP for biliary obstruction due to choledocholithiasis or postoperative biliary stricture.

Introduction: Very early recurrence in pancreatic ductal adenocarcinoma has been defined as recurrence ≤3 months after resection. Besides others, neoadjuvant treatment is delivered based on the assumption of preoperative eradication of micrometastasis as well as local downstaging. Prognostic factors of very early recurrence after neoadjuvant treatment remain largely unexplored.

Background: Limited data exists regarding the incidence of aborted pancreatic surgery due to radiologically occult metastatic disease (ROMD). This study presents a single-institution experience aimed at identifying potential risk factors associated with ROMD of patients undergoing routine preoperative magnetic resonance imaging with pancreatic ductal adenocarcinoma (PDAC) METHODS: Patients with PDAC taken for curative intent pancreatic surgery between January 2012 and December 2022 following preoperative imaging MRI protocol were retrospectively reviewed, and those who had aborted surgery due to ROMD were identified. Binary logistic regression analysis was performed to identify potential predictors of ROMD.
