Pilot study of screening method for pancreatic cancer using lipidomic profiling of plasma or serum
Pancreatic cancer is often diagnosed too late because early symptoms are vague and difficult to recognize. Current blood markers do not reliably detect early-stage disease, and imaging methods can be uncomfortable or invasive. Earlier detection is critical to improve patient outcomes. This study shows that a simple blood test measuring lipid molecules, combined with the statistical analysis, can identify pancreatic cancer, including early stages, with high accuracy and may serve as a future screening tool for individuals at high risk.

This study highlights the use of lipidomic profiling as a novel metabolic biomarker for the early detection of pancreatic cancer. By analyzing lipid concentrations in plasma and serum, the method achieves high sensitivity and specificity, outperforming traditional biomarkers like CA 19-9.
The research focuses on developing a non-invasive, blood-based test for pancreatic cancer, addressing the limitations of current invasive and costly imaging methods. This approach offers a significant improvement in patient comfort and accessibility for screening.
A key application of the lipidomic profiling method is for screening high-risk individuals (HRI) for pancreatic cancer. The study demonstrates its reliability in this population, offering comparable specificity to established imaging methods and supporting its potential for clinical implementation.

High-Risk Individual Screening
Case Name: HRI Cohort (N=93)
Challenge: Detecting early-stage PDAC in asymptomatic high-risk individuals with vague symptoms.
Solution: Applied lipidomic profiling to prospectively collected samples from individuals with familial pancreatic cancer, chronic pancreatitis, or genetic susceptibility syndromes.
Outcome: Achieved 96% specificity compared to imaging (EUS/MRI), with 85 negative predictions and 4 incorrect predictions. Identified potential early metabolic changes in 4 individuals shifting towards a lower-confidence range after one year of follow-up.
