KLK3 and coronary artery disorder: Patient baseline prostate-specific antigen (PSA) ≧̸10 ng/ml (p = 0.000), multiple organ metastasis (p = 0.007), hypertension (p = 0.004), and coronary heart disease (p = 0.004) were associated with worse PFS; however, radiotherapy (p = 0.028) was linked to better PFS at univariate analysis in the overall cohort.
