Background: There is increasing need to evaluate the surgical indication of pancreatic cancer in very elderly patients. However, the available clinical data are limited, and the optimal treatment is still controversial. The aim of this study was to evaluate the benefit of pancreatic resection in pancreatic cancer patients over the age of 80.
Methods: Between 2005 and 2012, 26 octogenarian patients who received pancreatic resection and 20 who received chemotherapy for pancreatic cancer were retrospectively reviewed. Clinicopathological factors, chemotherapy administration status, and survival were compared. Univariate and multivariate analysis of prognostic factors for survival was performed.
Results: Postoperative major complication rate was 8%, with no mortality. The one-year survival rate and median survival time of the surgery and chemotherapy groups were 50% and 45%, and 12.4 months and 11.7 months, respectively (P = 0.263). Of the 26 resected cases, 6 completed the planned adjuvant chemotherapy treatment course. The median survival time of those 6 completed cases was significantly longer than that of the 20 not completed cases (23.4 versus 10.0 months, P = 0.034). Furthermore, a multivariate analysis of the 26 resected cases showed that distant metastasis (HR 3.206, 95%CI 1.005-10.22, P = 0.049) and completion of the planned adjuvant therapy (HR 4.078, 95%CI 1.162-14.30, P = 0.028) were independent prognostic factors of surgical resection.
Conclusions: Surgical resection was safe, but not superior to chemotherapy for pancreatic cancer in octogenarians. In the very elderly, only selected patients may benefit from pancreatic resection.

Agonistic anti-CD40 with anti-PD-1 can elicit objective responses in a small number of patients with pancreatic ductal adenocarcinoma (PDA). Better understanding of their individual effects on the PDA tumor microenvironment will help inform new strategies to further improve outcomes. Herein, we map tumor-specific CD8+ T-cell differentiation following agonistic anti-CD40 and/or anti-PDL1 in PDA.

Pyroptosis, a form of programmed cell death mediated by the gasdermin family, has emerged as a promising strategy for inducing anti-tumor immunity. However, efficiently inducing pyroptosis in tumor cells remains a significant challenge due to the limited activation of key mediators like caspases in tumor tissues. Herein, a self-priming pyroptosis-inducing agent (MnNZ@OMV) is developed by integrating outer membrane vesicles (OMVs) with manganese dioxide nanozymes (MnNZ) to trigger pyroptosis in tumor cells.

An association between gut microbiota and the development of pancreatic ductal adenocarcinoma (PDAC) has been previously described. To better understand the bacterial microbiota changes accompanying PDAC promotion and progression stimulated by inflammation and fecal microbiota transplantation (FMT), we investigated stool and pancreatic microbiota by 16s RNA-based metagenomic analysis in mice with inducible acinar transgenic expressions of KrasG12D, and age- and sex-matched control mice that were exposed to inflammatory stimuli and fecal microbiota obtained from mice with PDAC. Time- and inflammatory-dependent stool and pancreatic bacterial composition alterations and stool alpha microbiota diversity reduction were observed only in mice with a Kras mutation that developed advanced pancreatic changes.

Pancreatic cancer is one of the most common malignant tumors of the digestive system, with the majority of patients not succumbing to the primary tumor but rather to metastasis. Epithelial-mesenchymal transition (EMT) is abnormally activated in numerous cancers, whereby it promotes tumor cell migration and invasion. Yes-associated protein 1 (YAP1) is commonly overexpressed in various cancer types and plays an oncogenic role.

Objective: The aim of this study is to identify learning curves for robotic gastro-enterostomy (RGE) during RPD and the predictive value of the objective structured assessment of technical skills (OSATS) score for DGE according to the Birkmeyer et al and UPMC method.
Summary Of Background Data: In some series, robotic pancreatoduodenectomy (RPD) has been associated with increased risk of delayed gastric emptying (DGE). It is unclear whether this is attributable to learning curve.
