Abstract
Background
The prediction of prognostic outcomes can provide the most suitable strategy for patients with pancreatic ductal adenocarcinoma (PDAC). This study aimed to evaluate the clinical value of the preoperative tumor marker index (pre-TI) in predicting prognostic outcomes after resection for PDAC.
Methods
For 183 patients who underwent pancreatic resection of PDAC, adjusted carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen (CEA), pancreatic cancer-associated antigen-2 (DUpan-2), and s-pancreas-1 antigen (SPan-1) were retrospectively evaluated, and the positive number of these markers was scored as the pre-TI.
Results
A high pre-TI (≥ 2) was significantly associated with a larger tumor and lymph node metastases, and the patients with a high pre-TI had worse prognostic outcomes in terms of both relapse-free survival (RFS) (P < 0.0001, log-rank) and overall survival (OS) (P < 0.0001, Λlog-rank) than the patients with a low pre-TI. The pre-TI was one of the independent factors of a poor prognosis for RFS (hazard ratio [HR], 2.36; P < 0.0001) and OS (HR, 2.27; P < 0.0001). In addition, even for the patients with normal adjusted CA19-9 values (n = 74, 40.4%), those with the high pre-TI had a significantly poorer prognosis than those with a low pre-TI (RFS: P = 0.002, log-rank; OS: P = 0.031, log-rank).
Conclusions
The pre-TI could be a potent predictive marker of prognostic outcomes for patients with resections for PDAC. Patients with a high pre-TI may need additional strategies to improve their prognosis.
