Clinical and Biological Characterisation of Localised High-risk Prostate Cancer: Results of a Randomised Preoperative Study of a Luteinising Hormone-releasing Hormone Agonist with or Without Abiraterone Acetate plus Prednisone.

ABSTRACT: Optimal therapeutic strategy remains an unmet need in localised high-risk prostate cancer (LHRPC). Androgen biosynthesis inhibition in the preoperative setting may improve outcomes. In this single-centre randomised trial, we looked at therapy outcomes of preoperative treatment with abiraterone acetate+prednisone (AAP)+luteinising hormone-releasing hormone agonist (LHRHa) or LHRHa alone followed by radical prostatectomy in 65 men. We did not see a significant difference of organ-confined carcinoma (p=0.27). However, tumour volume measures were significantly lower for AAP+LHRHa treatment (p≤0.001). Of note, lower tumour epithelium volume correlated with improved biochemical recurrence-free survival at ≥4-yr follow-up (p=0.0014). Tumours pretreated with AAP+LHRHa had lower proliferation and a
