As pancreatic cancer progresses and spreads beyond the pancreas, abnormalities that are not specific to pancreatic cancer accumulate. As a result, marker behavior is likely to be significantly different among patients with early-versus late-stage pancreatic cancer (see Fig. 1).he production of tumor markers at different stages in the natural history of pancreatic cancer development. Markers that become readily detectable only in advanced stages of pancreatic ductal adenocarcinoma after the onset of clinical symptoms will not provide opportunities for early detection and cure.
