After adjusting for all possible covariates by using Cox regression hazard models, high expression levels of GAL1 in UTUC tumors was an independent predictive factor for RFS (hazard ratio (HR) 2.43; 95% CI 1.17–5.05, p = 0.018) and CSS (HR 4.04; 95% CI 1.25–13.03, p = 0.019; Table 2). This evidence concerns the gene GAL and renal pelvis/ureter urothelial carcinoma.
