Core Tip
Core tip: Pancreatic cancer (PC) is a leading cause of cancer-related death. PC mutations accumulate 20 years before patient death with metastatic mutations occurring late in the process. Metastatic risk increases dramatically when tumor diameter is greater than 1 cm. Most PC cases are diagnosed at late metastatic stages when survival is short. Outcomes could be improved if non-invasive methods could detect early stages of the disease and guide treatment decisions. Recent studies indicate this may be possible with application of digital pathology imaging, screening of CA 19-9 with additional markers, and detecting circulating tumor material in early-stage PC patients.
