Also, a meta-analysis of seven microarray datasets and the TCGA PAAD cohort verified the remarkable overall association of ITGA3 with PCa prognosis (HR = 1.38, 95% CI 1.26–1.51, p < 0.00001), indicting ITGA3 was a potential prognostic biomarker in PCa. This evidence concerns the gene ITGA3 and pancreatic adenocarcinoma.
