Background: We aimed to explore the predictive ability of preoperative carbohydrate antigen 19‐9 (CA19‐9) and carcinoembryonic antigen (CEA) levels for assessing tumor resectability (R0 resection) in patients with pancreatic adenocarcinoma. Methods: The present study included 72 patients who had been treated surgically for potentially resectable pancreatic adenocarcinoma and 42 patients who had been treated surgically for palliation (bypass surgery) at our institution. Pancreatic adenocarcinoma was histologically confirmed by pathological examination of the resected specimen or, if unresected, by intraoperative biopsy. Results: For resectable disease, the mean and median values of CA19‐9 were significantly lower than for R1/2 or unresectable disease. The best cut‐off points for CEA, CA19‐9, and tumor size to predict resectability were 2.47 ng/mL, 92.77 U/mL and 11.85 cm 3 , respectively. A CA19‐9 ≥ 92.77 U/mL and both tumor markers no less than the cut‐off levels predicted the possibility of R1/2 or unresectability with 90.6% and 88.6% accuracy, respectively. However, either tumor marker or both tumor markers less than the cut‐off levels predicted the probability of R0 resection only with 27.1% and 40.6% accuracy, respectively. The independent contributing factors to resectability (R0 resection) by multivariate regression analysis were a CA 19‐9 < 92.77 U/mL, a tumor size < 11.85 cm 3 , and a less advanced AJCC stage. Conclusion: The present study demonstrates that preoperative serum CA19‐9 and CEA levels can be used for the prediction of resectability (R0 resection) in patients with pancreatic adenocarcinoma, which may enable a simple and cost‐effective exclusion of such patients who are unlikely to benefit from surgery.
