Abstract

Pancreatic cancer (PC) is a devastating disease, due in part to its diagnosis frequently being made at an advanced stage. Ongoing efforts are aimed at identifying early-stage PC in high-risk individuals, as early detection leads to downstaging of PC and improvements in survival. However, there are a myriad of challenges that arise when trying to optimize PC early detection strategies, including selection of the appropriate high-risk individuals and selection of the test or combination of tests that should be performed. Here, we discuss the populations that are the strongest candidates for PC screening and review professional PC screening guidelines. We also summarize the current state of imaging techniques for early detection of PC and further review many studied biomarkers — ranging from nucleic acid targets, proteins, and the microbiome — to highlight the current state of the field and the challenges that remain in the years to come.
