Overview
This trial aims to evaluate the efficacy and safety of neoadjuvant therapy with Darolutamide combined with Androgen-Deprivation Therapy in High-risk/Very high-risk localized prostate cancer. This trial is A prospective, single-arm, multicenter clinical trial. Treatment cycle is 24 weeks,
Description
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 Darolutamide in neoadjuvant therapy for surgically resectable high-risk or very high-risk PCa.
