Kaplan-Meier analyses of PFS. (A) The analysis of PFS resulted in a median PFS of 7 months for patients with a PSA-decline of 50% or more compared to 3 months when patients did not show that decline (P≤0.01); (B) considering ALP, median PFS was 8 vs. 3 months in favor of the presence of ALP-bouncing (P=0.013); (C) patients with LDH-normalization showed a median PFS of 6 months while the opposite led to a PFS of 2 months (P≤0.01). PFS, progression-free survival; PSA, prostate-specific antigen; ALP, alkaline phosphatase; LDH, lactate dehydrogenase; HR, hazard ratio; CI, confidence interval.
