Targeted Microwave Ablation for Prostate Cancer Under Magnetic Resonance Imaging-Ultrasound Fusion and Organ-based Tracking: Final Results from the First Phase 2 Trial (TMA-HK).

Targeted microwave ablation (TMA) is a novel focal therapy modality for prostate cancer (PC). TMA-HK is the first phase 2 trial investigating the efficacy and functional outcomes of transperineal TMA (NCT04113811) in 30 men with low- or intermediate-risk PC. TMA was performed transperineally with magnetic resonance imaging (MRI)-ultrasound fusion guidance and organ-based tracking.

A prospective evaluation of the effect of finasteride on prostate health index (phi).

Purpose: 5-alpha reductase inhibitor (5ARI) reduces prostate-specific antigen (PSA) by half but its effect on prostate health index (phi) is unknown. This study aims to investigate this effect and to enable accurate interpretation of phi in men with elevated PSA and on 5ARI.

Methods: This is a prospective study evaluating the effect of finasteride on PSA, free PSA (fPSA), [ - 2]proPSA (p2PSA) and phi at 6 and 12 moths in men with PSA 4-20 ng/mL, no prior 5ARI use, and one negative prostate biopsy within 6 months before recruitment.

Transperineal Targeted Microwave Ablation (TMA) of localized prostate cancer guided by MRI-Ultrasound fusion and organ-based tracking: a pilot study.

Background: To investigate the efficacy of transperineal targeted microwave ablation (TMA) in treating localized prostate cancer (PCa).

Methods: This is a single-centre prospective phase 2 trial recruiting men with low to intermediate-risk localized PCa to undergo transperineal TMA. TMA was performed with MRI-Ultrasound fusion guidance and organ-based tracking.

Initial Prostate Health Index (phi) and phi density predicts future risk of clinically significant prostate cancer in men with initial negative prostate biopsy: a 6-year follow-up study.

Background: Men with elevated prostate-specific antigen (PSA) and initial negative prostate biopsy may have risk of prostate cancer (PCa) in the future. The role of Prostate Health Index (phi) in determining future PCa risk has not been studied before. This study aims to investigate the role of initial phi and phi density in predicting future PCa risk in men with initial negative biopsy.
