LGALS1 and renal pelvis/ureter urothelial carcinoma: 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).
