Special Issue Information

Dear Colleagues,

Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, characterized by an aggressive biological profile, late-stage diagnosis, and limited response to existing therapies. Despite significant advancements in our understanding of the molecular and cellular biology of PDAC, its prognosis continues to be poor, with a five-year survival rate of less than 10%. These outcomes are largely driven by the tumor’s complex biology, its propensity for early dissemination, and the challenges in achieving timely diagnosis.

Recent research has provided critical insights into the genetic and molecular landscape of PDAC, offering new opportunities for early detection and targeted therapies. Biomarkers for early diagnosis and risk stratification are an area of active exploration, with the potential to identify patients at earlier, more treatable stages of the disease. Surgical resection remains the cornerstone of curative treatment, yet it is only feasible in a minority of cases due to late-stage presentation. Advances in surgical techniques, including minimally invasive and robotic approaches, aim to optimize patient outcomes while minimizing perioperative morbidity. Moreover, managing postoperative complications, such as pancreatic fistulas, remains a key challenge in improving recovery and long-term survival.

Neoadjuvant and adjuvant therapies are increasingly being integrated into the standard of care, offering opportunities to downstage borderline resectable tumors and enhance the effectiveness of surgery. However, the optimal sequencing, combination, and personalization of these therapies are subjects of ongoing research and debate.

This Special Issue of Medicina focuses on the intersection of tumor biology, early detection, surgical innovation, and multimodal therapy in pancreatic cancer. We aim to highlight cutting-edge research and clinical advances in the following areas:

  • Tumor biology and the genetic and molecular mechanisms driving PDAC progression;
  • Biomarkers and novel strategies for early diagnosis and risk stratification;
  • Innovations in surgical techniques, including robotic and minimally invasive approaches;
  • Management and prevention of postoperative complications;
  • Advances in neoadjuvant and adjuvant therapy protocols and their integration into clinical practice.

By gathering contributions from leading experts, this Special Issue seeks to provide a deeper understanding of the disease and its management, with the ultimate goal of improving early detection and optimizing therapeutic strategies to enhance patient outcomes.

Background and Objectives: Metastatic pancreatic ductal adenocarcinoma carries a dismal prognosis and there is an unmet need for simple, widely available prognostic biomarkers to guide risk stratification and treatment planning. This study aimed to evaluate whether baseline EASIX score, calculated from routine laboratory parameters (LDH, creatinine, platelet count), predicts overall survival (OS) in patients with de novo metastatic pancreatic cancer. Materials and Methods: We performed a retrospective cohort study at a single tertiary center (Medical Oncology Department, Kocaeli University Faculty of Medicine) including 332 patients diagnosed with de novo metastatic pancreatic ductal adenocarcinoma between January 2019 and October 2025. Baseline EASIX was calculated using LDH, creatinine, and platelet count. Statistical analyses included ROC analysis with Youden index to determine exploratory cut-off, Kaplan–Meier survival estimation with log-rank test, and univariate and multivariate Cox proportional hazards regression to identify independent prognostic factors. The primary endpoint was OS, defined as time from initiation of first-line therapy to death from any cause. Results: A total of 332 patients were included. Median OS was 8.0 months overall. Patients with high EASIX (>2.505) had significantly shorter median OS compared with low EASIX patients (8.4 vs. 27.6 months, p < 0.001). ROC analysis was considered exploratory for overall survival; therefore, an additional fixed-time (12-month mortality) ROC analysis was performed to provide a discrimination estimate accounting for censoring. The AUC for EASIX was 0.887 (95% CI: 0.816–0.958), and the exploratory cut-off determined was 2.505 (sensitivity 96.95%, specificity 72.97%). In multivariate Cox regression, high EASIX remained an independent predictor of worse OS (HR 4.124; 95% CI: 2.011–8.457; p < 0.001) after adjustment for relevant covariates. Conclusions: Baseline EASIX score is an independent prognostic marker for overall survival in de novo metastatic pancreatic cancer, based on routine laboratory tests, and may facilitate exploratory risk stratification. Prospective validation in independent cohorts is warranted before clinical implementation. Full article

Background and Objectives: Pancreatic ductal adenocarcinoma (PDAC) is among the most aggressive, heterogeneous, and lethal human malignancies, underscoring the urgent need for novel, targeted therapeutic strategies for neo(adjuvant) individualized treatment. The epidermal growth factor receptor family (ErbB) is directly involved in abnormal cell proliferation and tumor growth. The overexpression and amplification of HER2 and HER3 have emerged as key molecular events in pancreatic ductal adenocarcinoma. The aim of this study was to evaluate these membrane receptors’ overexpression in relation to pTNM staging, perineural and lymphovascular invasion, and tumor volume in order to obtain the immunohistochemical profile and enhance the development of a targeted and personalized therapy. Materials and Methods: An observational analytical cohort study included patients with histopathologically naïve, confirmed PDAC who underwent cephalic pancreatoduodenectomy at a national high-volume referral center between 2017 and 2022. Archived surgical specimens were retrieved and examined using a tissue microarray technique in two separate pathology departments by two independent pathologists. Results: HER2 positivity was found in 25 cases, of which 84% had lymphatic invasion, 50% had vascular invasion, and 84% had perineural invasion. Patients with HER3 positivity had lymphatic invasion (82.5%), perineural invasion (79.4%), and vascular invasion (38.1%). Combined HER2 and HER3 positivity was present in 19 cases, and these patients had 84.2% perineural invasion. Conclusions: HER2 and HER3 overexpression often coexisted with pathological features, such as perineural invasion, in cases of combined HER2 and HER3 positivity. These findings support the involvement of the ErbB receptor family in pancreatic carcinogenesis and suggest their potential as targets for future (neo)adjuvant therapeutic strategies. Full article

Background and Objectives: Pancreatic ductal adenocarcinoma (PDAC) is one of the leading causes of cancer-related mortality, largely due to late-stage diagnosis and the absence of effective population-based screening. Intrapancreatic fat deposition (IPFD) has emerged as a potential risk phenotype. This narrative review critically appraises the clinical, metabolic, epidemiologic, and mechanistic evidence linking IPFD to PDAC and discusses its implications for risk stratification and prevention. Materials and Methods: A structured literature search was conducted in PubMed/MEDLINE and Scopus for studies published between 2007 and 2025 using predefined terms related to pancreatic steatosis and pancreatic cancer. After duplicate removal and screening according to predefined inclusion and exclusion criteria, 42 articles were included. Evidence was synthesized focusing on epidemiologic associations, mechanistic pathways, and imaging-based quantification methods. Results: A strong association between IPFD and PDAC was found. Although definitive causality remains unproven, some studies support temporal correlation between IPFD and PDAC, suggesting that IPFD precedes PDAC. A possible pathophysiological explanation to this correlation has been advanced in experimental models indicating IPFD as a pro-inflammatory factor cooperating with oncogenic KRAS to facilitate neoplastic progression. Finally, variability in IPFD definitions and heterogeneity in imaging assessment limit interpretability. Conclusions: Current evidence links IPFD to PDAC risk, suggesting a strong suspicion that pancreatic steatosis may represent an independent risk factor for PDAC. Still robust causal inference remains unproven. Well-designed prospective studies, standardized imaging protocols, and mechanistic investigations are required to clarify causality and determine whether pancreatic steatosis can be incorporated into risk-based screening and preventive strategies.

The progression of pancreatic cancer (PC) is significantly influenced by the immune system. In the United States, PC is the third leading cause of cancer-related mortality. The high lethality of PC is attributed to its immunological advantage, which is facilitated by an immunosuppressive microenvironment, a low mutational burden, and minimal T-cell infiltration. Although immunotherapies, such as checkpoint blockades or genetically engineered T cells, have not yet demonstrated viability, there is a growing body of evidence suggesting that innovative combinations of conventional therapies and various procedures may lead to effective immunotherapy in the treatment of PC. This review focuses on the importance of the tumor microenvironment and the promising role of immunotherapies in PC. Full article

Background: Despite advances in chemotherapy and supportive care, pancreatic ductal adenocarcinoma (PDAC) continues to carry a dismal prognosis, with a five-year survival rate of approximately 13%. While immunotherapy has revolutionized treatment for several malignancies, its efficacy in PDAC remains limited. Recent research has shifted focus toward integrating immunotherapy with chemotherapy, radiation, and targeted therapies in an effort to overcome therapeutic resistance and improve outcomes. Ongoing clinical trials are actively investigating these multimodal strategies. Materials and Methods: A systematic search was conducted using PubMed and ScienceDirect to identify relevant studies published in the past six years. Search terms included “pancreatic adenocarcinoma immunotherapy,” “pancreatic cancer treatments,” and “combination treatments for pancreatic adenocarcinoma.” Only English-language articles were included. Results: A total of 126 articles were initially identified through the database search. After a full-text screening, 48 articles were deemed potentially relevant. Following a rigorous review, 11 studies met the inclusion criteria and were selected for analysis. These studies included randomized controlled trials, non-randomized controlled trials, and retrospective studies. Meta-analyses and case reports were excluded. Articles that failed to meet the inclusion criteria were excluded, primarily due to the absence of relevant data addressing the main objective of this review. Conclusions: Combination strategies with immunotherapy and chemotherapy offer modest survival gains in metastatic settings, yet efforts in resectable and borderline resectable disease have fallen short. These outcomes reflect the profound immunosuppressive forces of the PDAC microenvironment. A new era of treatment must move beyond broad immunotherapeutic applications toward a precision-driven model. Molecular markers, such as KRAS mutations and circulating tumor DNA (ctDNA) profiles, are beginning to illuminate paths for personalized therapy selection. Future progress will depend on biomarker-guided clinical trials, a deeper understanding of immune resistance mechanisms, and bold innovation at the intersection of immunology and tumor biology.
