Neoadjuvant Therapy of Abiraterone Plus ADT for High Risk Prostate Cancer

December 14, 2022 updated by: Hongqian Guo, The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

Medical Ethics Committee of Nanjing Drum Tower Hospital Affiliated to Medical School of Nanjing University

High risk prostate cancer (PCa) had worse outcomes on radical treatment results, short-time oncological results, even cancer-specific survival, than those low or mediate risk PCa. Neoadjuvant treatment before radical prostatectomy had been proven to get some benefits on peri-operation results, especially on reduction of tumor volume and minimization of biochemical recurrence. This study will evaluate the efficacy and safety of androgen deprivation therapy (ADT) with abiraterone in neoadjuvant therapy for surgically resectable high-risk or very high-risk PCa.
