Predictive Early Recurrence Factors of Preoperative Clinicophysiological Findings in Pancreatic Cancer

Background: We aimed to evaluate the use of preoperative clinicophysiological parameters as predictive risk factors for early recurrence of pancreatic ductal adenocarcinoma (PDAC) after curative resection. Methods: A total of 260 patients who underwent pancreatic resection for PDAC between 2007 and 2015 were examined retrospectively. We divided the patients into those with early recurrence (within 6 months; group A, n = 52) and those with relapse within ≥6 months or without recurrence (group B, n = 208). Data regarding clinicophysiological parameters were analyzed as predictors of disease-free survival (DFS). These factors were analyzed by χ² tests on univariate analysis and Cox proportional hazard models on multivariate analyses. Kaplan-Meier survival curves were generated using log-rank tests. Results: Groups A and B had significantly different preoperative carbohydrate antigen 19-9 (CA19-9) levels, carcinoembryonic antigen (CEA) levels, and curability. Univariate and multivariate analysis showed that CA19-9 and CEA were independent prognostic factors for early recurrence. Patients with CA19-9 levels #x3e; 124.65 U/mL had significantly shorter DFS than those with lower levels, as did patients with CEA levels #x3e; 4.45 ng/mL. Conclusions: Our results show that elevated CA19-9 (#x3e; 124.65 U/mL) and CEA (#x3e; 4.45 ng/mL) were independent predictors of early recurrence after pancreatic resection in PDAC patients.
