Neoadjuvant Therapy of Abiraterone Plus ADT for Intraductal Carcinoma of the Prostate

Summary

Neoadjuvant treatment before radical prostatectomy has been proven to provide 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 abiraterone acetate Plus androgen deprivation therapy（ADT）in high-risk localized prostate cancer with intraductal carcinoma of the prostate（IDC-P）.
