Table 3 Univariate and multivariate analyses of significant biomarkers for OS in 84 bmCRPC-patients under Abiraterone-therapy

From: Dynamic changes of alkaline phosphatase are strongly associated with PSA-decline and predict best clinical benefit earlier than PSA-changes under therapy with abiraterone acetate in bone metastatic castration resistant prostate cancer
