Objectives: As a strategy to diagnose early-stage pancreatic ductal adenocarcinoma (PDAC) is urgently needed, we aimed to clarify characteristics of early-stage PDAC. Methods: We retrospectively reviewed medical records of 299 consecutive patientswho underwent R0 or R1 surgical resection for PDAC between 1994 and 2013 and compared clinical characteristics between patients with early-stage (stages 0-I by Japanese General Rules for Pancreatic Cancer) and advanced-stage (stages II-IV) disease. Diagnostic processes were also analyzed. Results: Twenty-four patients (8%) had early-stage PDAC (stage 0: 11; stage I: 13). Univariate and multivariate analyses showed that presence or history of intraductal papillary mucinous neoplasm (P < 0.01), history of pancreatitis (P < 0.01), and presence or history of extrapancreatic malignancies (P = 0.01) independently predicted detection of early-stage PDAC. Cytological examination during endoscopic retrograde pancreatography cytology was ~65% sensitive in preoperative diagnosis of early-stage PDAC, whereas other imaging modalitieswere only 29% to 38%sensitive; 9 of 24 early-stage PDACs were diagnosed by endoscopic retrograde pancreatography cytology alone. Conclusions: Endoscopic retrograde pancreatography cytology for patients with intraductal papillary mucinous neoplasm or pancreatitis may help diagnose early-stage PDAC. Surveillance of extrapancreatic malignancies might also provide opportunities to detect early-stage PDAC as a second malignancy.
