BCR and neoplasm: The univariate Cox regression analysis revealed that in the entire cohort, the Gleason score (HR = 3.84, 95% CI: 2.13-6.91, P value < 0.001), risk score (HR = 2.56, 95% CI: 1.49-4.38, P value = 0.0007), lymph node (HR = 1.91, 95% CI: 1.07-3.42, P value = 0.03), tumor stage (HR = 5.03, 95% CI: 2.16-11.74, P value = 0.0002), and PSA (HR = 9.34, 95% CI: 3.95-22.06, P value < 0.001) were related to BCR-free, and the risk score, Gleason score, tumor stage, and PSA remained independent predictors via multivariate Cox regression analysis (Table 1).
