Univariate Cox regression model analysis showed that high ITGA3 expression level contributed to a poor prognosis in the TCGA PAAD cohort (HR = 1.464, 95% CI 1.203–1.783, p = 1.46 × 10−4) and in the PCa patients in datasets GSE79668 (HR = 1.502, 95% CI 1.181–1.911, p = 9.12 × 10−4), GSE78229 (HR = 1.513, 95% CI 1.122–2.042, p = 6.72 × 10−3), and GSE62452 (HR = 1.617, 95% CI 1.227–2.131, p = 6.50 × 10−4; Table 3). This evidence concerns the gene ITGA3 and posterior cortical atrophy.
