What this trial studies

This clinical trial investigates the use of high-intensity focused ultrasound (HIFU) for treating localized prostate cancer, aiming to assess its feasibility, safety, and functional outcomes compared to standard care. The study will involve a larger cohort of men to better represent the patient population, addressing the challenges faced by previous randomized controlled trials in this area. Participants will undergo various assessments, including quality-of-life evaluations and monitoring for therapy-related complications. The goal is to determine if HIFU can achieve similar or better outcomes than traditional treatments while minimizing side effects.

Who should consider this trial

Good fit: Ideal candidates are men with histologically proven localized prostate cancer who meet specific eligibility criteria regarding disease stage and biopsy results.

Not a fit: Patients with advanced prostate cancer or those with a life expectancy of less than 10 years may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a less invasive option for prostate cancer patients, potentially reducing side effects like erectile dysfunction and urinary incontinence.

How similar studies have performed: Previous trials using HIFU have shown promising results, but this study aims to expand on those findings with a larger and more diverse patient population.

Eligibility criteria

Show full inclusion / exclusion criteria
1. Histologically proven prostate cancer on trans-rectal or transperineal template prostate biopsies.
2. Prostate biopsy (either TRUS or MRI Targeted or Template):

   * TRUS biopsy: up to burden bilateral disease with maximum 3mm one biopsy on non-dominant side is allowable.
   * MRI targeted and/or Template biopsy within 12 months of entry showing:
   * unilateral disease minimum 3mm of Gleason 3+3 or any Gleason 3+4 or 4+3 but not exceeding Gleason 4+3 overall OR
   * bilateral disease presence of clinically significant cancer on only one side (as determined by histological rules described above) Gleason ≤7 which is concordant with the MRI findings.
3. Stage T1-T2cN0M0 disease, as determined by local guidelines (radiological T3a permitted).
4. Serum PSA \</=20ng/ml
5. Life expectancy of \>/=10 years.
6. Signed informed consent by patient.
7. An understanding of the English language sufficient to understand
