• Differences in the Fecal Metabolome of AutoimmunePancreatitis Patients

  Published: 17 April 2025
  
  Abstract
  Background
  Chronic pancreatitis is a risk factor for pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis that is primarily characterized by its immune mediate etiology, clinically resembling pancreatic cancer, yet uniquely responsive to steroid treatment.
  
  Objective
  Early and accurate diagnosis of autoimmune pancreatitis is vital for effective treatment and patient prognosis, for which new diagnostic tools are urgently required. Gut microbiota dysbiosis has been identified to correlate with the development of pancreatic diseases, which provides new opportunities for the discovery of disease biomarkers.
  
  Methods
  We utilized a mass spectrometric global metabolomics investigation of patient autoimmune pancreatitis and chronic pancreatitis fecal samples, investigating microbiome, dietary and human metabolism.
  
  Results
  We discovered a series of newly identified metabolic signatures between both patient groups including enterolactone, 4-guanidinobutanoic acid, and methylthioadenosine sulfoxide. Additionally, the analysis revealed significant differences in several metabolic pathways such as fatty acids, alkaloids, amino acids and peptides.
  
  Conclusion
  Our observations provide novel insights into important metabolic human pathways and microbiome-derived metabolites to distinguish autoimmune pancreatitis from chronic pancreatitis. These findings reveal systemic metabolic responses and the identified metabolites may be developed into potential biomarkers for future diagnosis to distinguish between autoimmune pancreatitis and chronic pancreatitis.

• Pancreatic incidentaloma: incidental f indings from history towards the era of liquid biopsy

  Matthias Löhr, Miroslav Vujasinovic, Nikolaos Kartalis, Philipp Osten
  
  Published: 9 September 2024
  
  Abstract
  This report provides an overview of the most common diagnostic methodss that bring to light incidental findings of pancreatic cancer. It reviews the impact of medical imaging and genetic assessment on the definitions of incidental findings and incidentaloma of the pancreas. For different diagnostic approaches (eg, MRI and CT) and for different affections (cysts/intraductal papillary mucinous neoplasia, solid lesions), specific guidelines have been proposed and some are established. Based on this, we summarise the differences between the traditional methods with those applied in the PANCAID project. Biomarkers, genetic predispositions, mutations and circulating tumour cells give rise to different levels of concern. The final part of the report discusses the risks and the opportunities associated with further diagnostic procedures and surgical interventions. From the ethical perspective, the most urging question is, can a screening based on liquid biopsy and blood samples open a gateway for the prevention of pancreatic cancer - even if morbidity and lethality of today’s surgical interventions is still very high?

• Multibiomarker panels in liquid biopsy for early detection of pancreatic cancer – a comprehensive review

  Kim‑Lea Reese, Klaus Pantel and Daniel J. Smit
  
  Published: 2 September 2024
  
  Abstract
  Pancreatic ductal adenocarcinoma (PDAC) is frequently detected in late stages, which leads to limited therapeutic options and a dismal overall survival rate. To date, no robust method for the detection of early-stage PDAC that can be used for targeted screening approaches is available. Liquid biopsy allows the minimally invasive collection of body fluids (typically peripheral blood) and the subsequent analysis of circulating tumor cells or tumor-associated molecules such as nucleic acids, proteins, or metabolites that may be useful for the early diagnosis of PDAC. Single biomarkers may lack sensitivity and/or specificity to reliably detect PDAC, while combinations of these circulating biomarkers in multimarker panels may improve the sensitivity and specificity of blood test-based diagnosis. In this narrative review, we present an overview of different liquid biopsy biomarkers for the early diagnosis of PDAC and discuss the validity of multimarker panels.

• Economic evaluations of pancreatic cancer screening: a systematic review protocol

  Robert Wittram, Hans-Helmut König, Christian Brettschneider
  
  Published: 17 August 2024
  
  Abstract
  Introduction: The early detection of pancreatic cancer is an important step in reducing mortality by offering patients curative treatment. Screening strategies in risk populations and by means of different detection methods have been economically evaluated. However, a synthesis of screening studies to inform resource allocation towards early detection within the disease area has not been done. Therefore, studies evaluating the cost-effectiveness and costs of screening for pancreatic cancer should be systematically reviewed.
  
  Methods and analysis: A systematic review of economic evaluations reporting the cost-effectiveness or costs of pancreatic cancer screening will be conducted. The electronic databases Medline, Web of Science and EconLit will be searched without geographical or time restrictions. Two independent reviewers will select eligible studies based on predefined criteria. The study quality will be assessed using the Consolidated Health Economic Evaluation Reporting Standards statement and the Bias in Economic Evaluation checklist. One reviewer will extract relevant data and a second reviewer will cross-check compliance with the extraction sheet. Key items will include characteristics of screened individuals, the screening strategies used, and costs, health effects and cost-effectiveness as study outputs. Differences of opinion between the reviewers will be solved by consulting a third reviewer.
  
  Ethics and dissemination: Ethics approval is not required for this study since no original data will be collected. The results will be disseminated through presentations at conferences and publication in a peer-reviewed journal. The results of the systematic review will inform future economic evaluations of pancreatic screening, which provide guidance for decision-making in healthcare resource prioritisation.

• Can our experience with surveillance for inherited pancreatic cancer help to identify early pancreatic cancer in the general population?

  J.-Matthias Löhr, Daniel Öhlund, Emma Söreskog, Emil Andersson, Miroslav Vujasinovic, Niklas Zethraeus, Malin Sund
  
  Published: 5 March 2024
  
  Abstract
  Screening of the general population for cancer is a matter of primary prevention reducing the burden of disease. Whilst this is successful for several cancers including breast, colon and prostate, the situation to screen and hence prevent pancreatic cancer is different. The organ is not as accessible to simple physical exam or biological samples (fecal or blood
  test). Neither exists a blood test such as PSA that is cost-effective. Reviewing the evidence from screening risk groups for pancreatic cancer, one must conclude that there is no rational at present to screen the general population, for a lack of appropriate tests.

• Liquid Biopsy: From Discovery to Clinical Application

  Catherine Alix-Panabières and, Klaus Pantel (2021)
  
  Over the past 10 years, circulating tumor cells (CTC) and circulating tumor DNA (ctDNA) have received enormous attention as new biomarkers and subjects of translational research. Although both biomarkers are already used in numerous clinical trials, their clinical utility is still under investigation with promising first results. Clinical applications include early cancer detection, improved cancer staging, early detection of relapse, real-time monitoring of therapeutic efficacy, and detection of therapeutic targets and resistance mechanisms. Here, we propose a conceptual framework of CTC and ctDNA assays and point out current challenges of CTC and ctDNA research, which might structure this dynamic field of translational cancer research. SIGNIFICANCE: The analysis of blood for CTCs or cell-free nucleic acids called "liquid biopsy" has opened new avenues for cancer diagnostics, including early detection of tumors, improved risk assessment and staging, as well as early detection of relapse and monitoring of tumor evolution in the context of cancer therapies.
