Background: Advanced pancreatic cancer is resistant to chemotherapeutic drugs, resulting in limited treatment efficacy and poor prognosis. Combined administration of the chemotherapeutic gemcitabine and erlotinib is considered a potential first-line treatment for advanced pancreatic cancer. However, their comparative benefits and potential risks remain unclear.
Aim: To assess the clinical efficacy and safety of erlotinib combined with other chemotherapy regimens for the treatment of advanced pancreatic cancer.
Methods: Literature on the clinical efficacy and safety of erlotinib combined with chemotherapy for advanced pancreatic cancer was retrieved through an online search. The retrieved literature was subjected to a methodological qualitative assessment and was analyzed using the RevMan 5.3 software. Ten randomized controlled trials involving 2444 patients with advanced pancreatic cancer were included in the meta-analysis.
Results: Compared with chemotherapeutic treatment, erlotinib combined with chemotherapy significantly prolonged the progression-free survival time of pancreatic cancer patients [hazard ratio (HR) = 0.78, 95%CI: 0.66-0.92, = 0.003]. Meanwhile, the overall survival (HR= 0.99, 95%CI: 0.72-1.37, and = 0.95) and disease control rate (OR = 0.93, 95%CI: 0.45-0.91, = 0.84) were not significantly favorable. In terms of safety, the erlotinib and chemotherapy combination was associated with a significantly higher risk of diarrhea (OR = 3.59, 95%CI: 1.63-7.90, < 0.05) and rash (OR = 3.63, 95%CI: 1.64-8.01, < 0.05) compared with single-agent chemotherapy. Moreover, the risk of vomiting (OR = 1.27, 95%CI: 0.62-2.59, = 0.51), regurgitation/anorexia (OR = 1.61, 95%CI: 0.25-10.31, = 0.62), and infection (OR = 0.72, 95%CI: 0.28-1.87, = 0.50) were not significant in either group.
Conclusion: Compared with a single chemotherapeutic modality, erlotinib combined with gemcitabine can prolong progression-free survival in pancreatic cancer, but does not improve survival benefit or disease control rate, and can increase the risk of diarrhea and rash.

Immune system functions play crucial roles in both health and disease, and these functions are regulated by their metabolic programming. The field of immune engineering has emerged to develop therapeutic strategies, including polymeric nanoparticles (NPs), that can direct immune cell phenotype and function by directing immunometabolic changes. Precise control of bioenergetic processes may offer the opportunity to prevent undesired immune activity and improve disease-specific outcomes.

In 1982, the RAS genes HRAS and KRAS were discovered as the first human cancer genes, with KRAS later identified as one of the most frequently mutated oncogenes. Yet, it took nearly 40 years to develop clinically effective inhibitors for RAS-mutant cancers. The discovery in 2013 by Shokat and colleagues of a druggable pocket in KRAS paved the way to FDA approval of the first covalently binding KRAS inhibitors, sotorasib and adagrasib, in 2021 and 2022, respectively.

Chronic damage following oncogene induction or cancer therapy can produce cellular senescence. Senescent cells not only exit the cell cycle but communicate damage signals to their environment that can trigger immune responses. Recent work has revealed that senescent tumor cells are highly immunogenic, leading to new ways to activate antitumor immunosurveillance and potentiate T cell-directed immunotherapies.

Background: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) has become essential for diagnosing pancreatic ductal adenocarcinoma (PDAC) and is increasingly utilized for comprehensive genome profiling (CGP) to advance precision medicine. This systematic review and meta-analysis assess the feasibility and clinical utility of EUS-TA samples for CGP in PDAC.
Methods: We conducted a thorough systematic literature search in PubMed, EMBASE, and the Cochrane Library up to October 2023.
