Investigation of Programmed Death Ligand-1 as a New Prognostic Biomarker in Pancreatic Cancer Patients.

ABSTRACT: Pancreatic cancer is one of the most lethal and fast-growing cancers with a poor prognosis. Herein, we report the expression of programmed death ligand 1 (PD-L1) as a new prognostic biomarker in pancreatic cancer progression analysis at the clinical level. Immunohistochemistry was performed on 86 clinically proven cases of pancreatic cancer tissue microarrays (TMAs) using anti-PD-L1 antibodies. Histoscore was done, and a variety of cutoffs were identified for analyses of the results. The chi-square test and Kaplan-Meier method were used to find the association between pancreatic cancer and various clinicopathological variables and the overall survival of the patients. PD-L1 expression was associated with histological grade and recurrence of the disease for epithelial and stromal staining a
