Darolutamide ± ADT as Neoadjuvant Therapy in High-Risk/Very High-Risk Localized Prostate Cancer

Plain-language summary

This is a two-Parallel cohort, prospective study, aimed to explore Efficacy and safety of neoadjuvant Darolutamide with or without ADT in high-risk/very high-risk localized-stage prostate cancer. Two parallel cohorts will enroll 30 patients with high-risk/very high-risk localized-stage prostate cancer according to the criteria, respectively. Eligible patients in cohort 1 will receive 600 mg of Darolutamide orally daily, and patients in cohort 2 will receive 600 mg of Darolutamide orally daily combined with ADT. The selection of the two parallel cohorts will be determined by the clinician. Considering that ADT treatment will bring typical adverse-reactions such as hot flashes, gynecomastia, fatigue, and sexual dysfunction, the clinician will decide the enrollment cohort based on the patient's specific clinical condition. After both cohorts receive 3-6 months of neoadjuvant treatment, these patients will receive robotic-assisted laparoscopic prostatectomy (RALP) ± standard lymph node dissection (LND), and the specific surgical plan will be formulated by the clinician. Patients will receive postoperative adjuvant therapy as same as the original prescription according to different conditions (the application of postoperative adjuvant radiotherapy is determined by the clinician). Follow-up: (1) PSA and testosterone levels: Monitor monthly for the first 6 months. Monitor every 3 months within 2 years. Monitor every 6 months thereafter. (2) Radiological evaluation: Monitor every 6 minutes within 2 years after surgery, and every 12 minutes thereafter.
