Abstract

INTRODUCTION: Lymph-nodal involvement (N+) represents an adverse prognostic factor after pancreatoduodenectomy (PD) for pancreatic adenocarcinoma (PDAC). Preoperative diagnostic and staging modalities lack sensitivity for identifying N+. This study aimed to investigate preoperative CA19.9 in predicting the N+ stage in resectable-PDAC (R-PDAC).

METHODS: Patients included in a multi-institutional retrospective database of PDs performed for R-PDAC from January 2000 to June 2021 were analyzed. A preoperative laboratory value of CA19.9 >37 U/L was used in univariate and multivariate logistic regression analysis to determine a possible association with N+. Additionally, different cut-offs of CA19.9 related to the preoperative clinical T (cT) stage was assessed to evaluate the risk of N+.

RESULTS: A total of 2034 PDs from thirteen centers were included in the study. CA19.9>37 U/L was significantly associated with higher N+ at univariate and multivariate analysis (P<0.001). CA19.9 levels >37 U/L were associated with N+ in 75.9%, 81.3%, and 85.7% of patients, respectively, in cT1, cT2, and cT3 tumors and with higher cut-off values for all cT stages.

CONCLUSION: Lymph nodal involvement is strongly related to preoperative CA19.9 levels. Specially in patients staged as cT3 the CA 19.9 could represent a valid and easy tool to suspect nodal involvement. Due to these findings, R-PDAC patients with elevated CA19.9 values should be considered in a more biologically advanced stage.
