Neoadjuvant High Dose Rate Brachytherapy Prior to Radical Prostatectomy in Patients With Prostate Cancer

Description

Approximately, 29 cancer patients will be enrolled. Patients will receive a single fraction of HDR-B (15Gy) 4-8 weeks prior to RALP.

Patients with HR-PCa who are in the upper tercile of Decipher genomic risk (≥0.85) or have pathologically node-positive disease after lymph node dissection will receive 3 months of adjuvant AAB beginning two months post-RALP, as this is SOC for this type of patient. Node positive patients will also receive adjuvant pelvic radiation as this is SOC for this type of patient.

The primary objectives of the study will be to assess the feasibility and safety of adding HDR-B prior to RALP for patients with newly diagnosed HR-PCa and to measure per-protocol treatment compliance.

Patients will be on the study for a total of up to 27 months, including 2-3 months on active study intervention (HDR-B with RALP 4-8 weeks post HDR-B) and potentially an additional 3 months (AAB).

Study follow-ups will be performed per-protocol for up to 2 years after surgery.
