Medical Suitability

Before you can have any focal therapy treatment, our expert team will review your existing medical information, including your diagnosis details, medical history, mpMRI scan and biopsy results. This will help them determine if focal therapy is the best treatment for your prostate cancer.


Ideal patients for Focal Therapy

Ideal patients for Focal Therapy

  • Low-Risk and Intermediate-Risk Prostate Cancer
    Patients with a Gleason score of 6 or 7, with grade group 1 to 3 cancers (which indicates less aggressive cancer) are the best candidates.
  • Tumors Confined to the Prostate
    The effectiveness of focal therapy depends on whether the cancer is restricted to one or a few distinct areas within the prostate.
  • PSA Levels Below a Certain Threshold
    Candidates typically have a prostate-specific antigen (PSA) level of 20 ng/mL or lower.
  • No Evidence of Metastasis
    Focal therapy is only suitable for patients whose cancer is localized and has not spread to lymph nodes, bones, or other distant areas.
  • Patients Seeking a Less Invasive Treatment
    Men who prefer to avoid the potential side effects of surgery or whole-gland prostate radiation may find focal therapy a more attractive option.

Patients who may not be eligible

  • High-Risk or Aggressive Tumors
    Patients with Gleason scores of 8-10, with grade group 4 or 5 cancers, typically have more aggressive cancers that are more likely to recur.
  • Widespread Cancer in Multiple Extensive Areas of the Prostate
    If cancer is spread outside the capsule of the prostate, focal therapy may leave untreated areas, leading to recurrence.
  • Very High PSA Levels
    Patients with PSA levels significantly above 20 ng/mL are more likely to have extensive disease that cannot be effectively treated with focal therapy alone.
  • Men Who Want a Single Definitive Treatment
    Some patients prefer a one-time treatment option that eliminates cancer with minimal risk of recurrence, and also accept the potential side effects of traditional treatment.

Which Focal Therapy is suitable for you?

HIFU

High-intensity focused ultrasound (HIFU) is one of two types of focal therapy we offer. It uses ultrasound waves to target cancer in the lower, or posterior, part of your prostate. HIFU is a non-invasive treatment that is guided by advanced 3D MRI imaging to destroy cancer cells while protecting healthy tissues.
  • Soundwave-based treatment
  • Preserves urinary and sexual function
  • Day procedure and rapid recovery

NanoKnife

NanoKnife is the other type of focal therapy we offer and uses electrical pulses to target the upper, or anterior, part of your prostate. Guided by 3D MRI imaging, NanoKnife is a minimally-invasive treatment that destroys cancer cells that may be hard to reach with HIFU.
  • Needle-based treatment
  • Preserves urinary and sexual function
  • Day procedure and rapid recovery

Questions to ask your doctor

Am I a good candidate for HIFU prostate cancer treatment?
HIFU (High-Intensity Focused Ultrasound) is ideal for men with localised, intermediate-risk prostate cancer. This typically includes a Gleason score of 3+4 or 4+3, a PSA level under 15–20 ng/mL, and cancer confined to one area of the prostate.

It’s especially suitable if you want to avoid side effects like incontinence or erection problems, which are more common with surgery or radiotherapy. You should also be healthy enough to live at least 8–10 more years, and your MRI and biopsy should show a clearly targetable cancer spot.

Would you like to explore this further?
Is HIFU available at your clinic, and how experienced is the team?
Yes, HIFU is available at The Focal Therapy Clinic. The clinic specialises in focal therapy treatments, including HIFU, which uses sound waves to precisely target and destroy cancer cells while sparing healthy tissue.

The team at the clinic has over 75 years of combined experience in urology, radiology, and oncology. They have treated over 2,000 patients and achieved excellent results, with 90% of men being free of clinically significant cancer one year after treatment.

The clinic uses advanced 3D MRI imaging for precision and has been a leader in focal therapy for over 20 years.
How does HIFU compare to other treatments like NanoKnife, surgery or radiotherapy?
Here’s a quick comparison:

Treatment Cancer Control Side Effects Recovery Time
HIFU Excellent (localised) ✅ Lower risk ✅ Few days
NanoKnife Excellent (localised) ✅ Lower risk ✅ Few days
Surgery >95% survival ❌ Higher risk ❌ Weeks/months
Radiotherapy Excellent ❌ Moderate risk ❌ Weeks

HIFU vs NanoKnife
- HIFU: Best for cancers in the back or middle of the prostate.
- NanoKnife: Ideal for cancers in the front or near nerves.

HIFU vs Surgery
- HIFU: Minimally invasive, fewer side effects.
- Surgery: Effective but higher risks of incontinence and erectile issues.

HIFU vs Radiotherapy
- HIFU: Focused only on the cancerous area.
- Radiotherapy: Treats the whole prostate, more side effects.
How many times can HIFU be repeated if cancer comes back?
HIFU can be safely repeated if cancer returns in the treated area. About 15–20% of men may need a second HIFU session, and it’s usually very effective.

Because HIFU targets just the cancerous spot, healthy tissue is preserved. This makes repeated treatment safer than surgery or radiotherapy.

PSA tests, MRI scans, and sometimes biopsies help decide if more treatment is needed. If HIFU fails more than once, other options like NanoKnife, surgery, or radiotherapy are still available.
What are the success rates and potential side effects for my specific case?
Success Rates:
- 88% of men avoid further treatment for at least 5 years.
- 98% have no cancer spread.
- 99% are still alive overall.
- Even better results for Gleason 6 or 7 cancers.

Potential Side Effects:
- Urinary control: Only 2% need a pad temporarily.
- Erections: Over 90% maintain erections.
- Other risks: About 8.5% may get mild urinary infections.

HIFU is ideal if you want to avoid long-term side effects from surgery or radiotherapy.

Would you like to explore how HIFU compares to other treatments or discuss follow-up care?
What follow-up schedule should I expect?
Follow-up is essential after HIFU to monitor recovery and detect recurrence.

Follow-Up Schedule:
1. PSA tests every 3 months in the first year.
2. MRI scan at 12 months.
3. Biopsy only if MRI shows something concerning.
4. Regular checks for urinary and sexual health.

This schedule helps detect issues early and manage side effects effectively.

Would you like to know what to expect during each follow-up?

Frequently asked questions

Who is suitable for Focal Therapy?
Focal therapy is suitable for men with localised, low- to intermediate-risk prostate cancer, typically with a Gleason score of 7 or lower (ISUP Grade 1–3). It is most effective when the cancer is confined within the prostate gland. This minimally invasive treatment preserves bladder, erectile, and bowel function, offering an alternative to surgery or radiotherapy while maintaining quality of life. Suitability depends on factors like PSA levels, biopsy results, and mpMRI scans, which are reviewed by expert urologists. Age alone is not a limiting factor; overall health and cancer aggressiveness are more important considerations.
Who isn’t an ideal candidate?
Men with high-risk or advanced prostate cancer, such as those with a Gleason score above 7 (ISUP Grade 4–5), or cancer that has spread beyond the prostate, are not ideal candidates for focal therapy. Additionally, those with large or multi-focal tumours, or cancer not clearly visible on an MRI, may require more extensive treatments like surgery or radiotherapy. Focal therapy is also less suitable for men in Cambridge Prognostic Groups 4 or 5, as these cases often involve more aggressive disease requiring comprehensive treatment.
What tests or diagnostic procedures are required to access eligibility?
To assess eligibility for focal therapy, the following tests and procedures are required:
  • MRI Scan: Provides a detailed image of the prostate to locate cancer spots accurately.
  • Biopsy: A small sample of prostate tissue is taken, often guided by MRI, to confirm the cancer's presence and grade.
  • PSA Test: Measures prostate-specific antigen levels in the blood to evaluate cancer activity.
  • PSMA PET CT Scan: Recommended in cases of higher-risk cancer to check for spread beyond the prostate.
These tests help doctors determine the cancer's size, location, and aggressiveness.
Are there specific disease stages or grades that make me suitable for focal therapy?
Yes, focal therapy is most suitable for men with early or intermediate-stage prostate cancer. Specifically:
  • Gleason Score: 7 or lower (Grade Groups 1–3), indicating low- to intermediate-risk cancer.
  • Disease Stage: Cancer confined within the prostate gland (localised disease).
  • Tumour Characteristics: Visible on MRI and not too large or multi-focal.
Men with these characteristics are more likely to benefit from focal therapy, as it targets specific cancer areas while preserving healthy prostate tissue and minimising side effects.
Am I eligible for focal therapy if I have multiple areas affected by the disease?
Focal therapy is generally less suitable for men with multiple areas of cancer (multi-focal disease). It works best when the cancer is localised to one main "index" lesion that can be targeted precisely. If multiple areas are affected, or if the cancer is extensive, whole-gland treatments like surgery or radiotherapy may be recommended instead. However, eligibility depends on the extent and location of the disease, which can be assessed through MRI scans and biopsies. Consulting with a specialist is essential to determine the best approach for your situation.
What role does my overall health play in determining eligibility?
Your overall health plays a crucial role in determining eligibility for focal therapy. Factors like comorbidities (other health conditions) and your general physical fitness can impact the safety and success of the treatment. For example:
  • Good Health: Increases the likelihood of a smooth recovery and better outcomes.
  • Chronic Conditions: Conditions like heart disease or diabetes may require additional consideration.
  • Mental Health: Anxiety or stress about cancer or treatment can influence decision-making.
A holistic assessment, including your lifestyle and health status, helps ensure the treatment aligns with your needs and goals.
Do I need to have failed previous treatments to qualify for focal therapy?
No, you do not need to have failed previous treatments to qualify for focal therapy. It is often used as a first-line treatment for men with localised, low- to intermediate-risk prostate cancer. However, if you have had prior treatments like radiation, focal therapy may still be an option in some cases, depending on the specifics of your cancer and overall health. Consulting with a specialist is essential to determine your suitability.
Can focal therapy be used alongside other treatments if necessary?
Yes, focal therapy can be used alongside or followed by other treatments if necessary. For example:
  • Retreatment with Focal Therapy: If cancer recurs, another round of focal therapy may be an option.
  • Surgery or Radiotherapy: These remain viable options after focal therapy if more extensive treatment is needed.
  • Hormone Therapy: Can be considered in certain cases, depending on the cancer's progression.
This flexibility allows focal therapy to be part of a broader treatment plan, preserving future options while minimising side effects initially.
How long will the treatment and recovery process be if I’m eligible for focal therapy?
If you're eligible for focal therapy, the treatment and recovery process is typically quick and minimally disruptive:

Treatment Duration

  • The procedure lasts about 60–90 minutes under anaesthesia.
  • It is usually performed as a day case, meaning you can go home the same day.

Recovery Process

  • First Few Days: You may have a urinary catheter for 3–5 days and experience mild discomfort in the perineum (area between the scrotum and back passage).
  • 1–2 Weeks: Most men feel fully back to normal within this time.
  • Temporary Side Effects: Some men may notice light bleeding in urine or semen, increased urinary frequency, or mild fatigue, but these usually resolve quickly.
Compared to surgery or radiotherapy, recovery is much faster, with fewer side effects.
How can I consult with a specialist to determine my eligibility for focal therapy?
To consult with a specialist and determine your eligibility for focal therapy, you can follow these steps:
  1. Initial Contact:
    - Reach out to The Focal Therapy Clinic by phone at 0207 036 8870 or email at info@thefocaltherapyclinic.co.uk.
    - Alternatively, complete the contact form available on their website.
  2. Suitability Assessment:
    - The clinic will assess your suitability for focal therapy by reviewing your biopsy and MRI results. They may also request additional tests if needed.
  3. Consultation Options:
    - You can book a consultation with one of their expert urologists, either in person or virtually, for convenience.
    - During the consultation, the specialist will discuss your cancer, treatment options, and any concerns you have.
  4. Next Steps:
    - If focal therapy is suitable, the clinic will guide you through the treatment process.
    - If not, they will help you explore alternative treatments.
Having a private consultation does not prevent you from accessing NHS treatment later, and it can provide a second opinion to help you make a confident decision.
