ProFocal® Therapy for Prostate Cancer: Targeting the Cancer While Preserving the Prostate

For many years, treatment for localised prostate cancer has involved either monitoring the whole prostate or treating the entire gland with surgery or radiotherapy. ProFocal® therapy represents a newer approach: using precisely delivered laser energy to destroy a selected cancerous area while leaving much of the surrounding prostate untreated.

This approach is known as focal laser therapy or focal laser ablation. Its aim is to achieve cancer control while reducing the risk of urinary incontinence, erectile dysfunction and other complications associated with whole-gland treatment.

Early Australian research is encouraging. However, ProFocal remains an investigational treatment, and important questions about its long-term cancer control have not yet been answered.

What is ProFocal therapy?

ProFocal is an Australian-developed focal therapy system designed to treat a carefully selected area of prostate cancer.

A fine laser applicator is inserted through the skin between the scrotum and anus—the perineum—and guided into the prostate using imaging. Laser energy heats the targeted tissue to a temperature that causes cancer-cell death.

The system incorporates cooling and real-time temperature monitoring. This is intended to make the area of ablation more predictable and to limit unintended heat damage to nearby structures such as the:

Urinary sphincter
Urethra
Bladder neck
Rectum
Neurovascular bundles involved in erections

Unlike radical prostatectomy, ProFocal does not remove the prostate. Unlike conventional radiotherapy, it does not expose the whole prostate to radiation.

Is ProFocal approved by the TGA?

This requires careful clarification.

As at September 2026, the manufacturer states that ProFocal is not included in the Australian Register of Therapeutic Goods—ARTG. It therefore does not have general TGA market authorisation for routine supply and use in Australia.

This is different from saying that the treatment has received unrestricted “TGA approval.”

ProFocal may be accessible in Australia through an approved clinical trial or a specific TGA access pathway, such as use by an appropriately authorised prescriber. For example, an Australian clinical trial investigating ProFocal for prostate cancer recurring after radiotherapy specifies that treatment is being provided by surgeons with TGA Authorised Prescriber approval.

Authorised Prescriber access does not mean that the device has been entered on the ARTG or endorsed as routine standard treatment. Regulatory status, trial availability and funding arrangements should always be confirmed directly before treatment.

Who may be considered for ProFocal therapy?

ProFocal is principally being studied in men with localised, non-metastatic and MRI-visible prostate cancer.

In the first prospective phase II ProFocal study, eligible men had:

Prostate cancer confined to the prostate
An MRI-visible cancer target
ISUP Grade Group 2 or 3 disease
A PSA of 15 ng/mL or lower
A clinical stage of T2c or lower
Biopsy findings corresponding with the abnormality seen on MRI

Outside a clinical trial, suitability would need to be assessed individually by a multidisciplinary prostate cancer team.

A potential candidate generally requires a cancer that can be clearly identified, biopsied and safely surrounded by an adequate treatment margin. Detailed assessment usually includes:

Multiparametric prostate MRI
Targeted and systematic transperineal biopsies
PSA and PSA-density assessment
Clinical staging
Consideration of PSMA PET/CT in selected men
Review of the MRI and pathology at a multidisciplinary meeting

When may ProFocal be unsuitable?

ProFocal would generally not be considered appropriate when there is:

Metastatic prostate cancer
High-risk or locally advanced disease requiring comprehensive treatment
Cancer outside the prostate
Extensive cancer involving several areas of the gland
Cancer that cannot be reliably identified on MRI
A tumour position where an adequate and safe treatment margin cannot be achieved
Significant uncertainty about the true extent or grade of the cancer
An inability or unwillingness to undergo ongoing MRI scans and repeat biopsies
A medical condition that makes anaesthesia or the procedure unacceptably risky

Men with low-risk Grade Group 1 prostate cancer may be better managed with active surveillance, avoiding treatment and its potential complications altogether.

Focal therapy should not be regarded as an easier substitute for appropriate surgery or radiotherapy in men with aggressive, high-volume or advanced prostate cancer.

How is ProFocal treatment performed?

ProFocal is usually performed as a day procedure under general anaesthesia.

Treatment planning

The cancer identified on MRI and biopsy is mapped carefully. The treatment plan includes the visible tumour and an additional safety margin intended to treat microscopic cancer immediately around it.

Placement of the laser applicator

With the patient under anaesthesia, a transrectal ultrasound probe is used to visualise the prostate. A fine laser applicator is inserted through the perineum and positioned within the selected treatment area.

The route is similar to that used for a transperineal prostate biopsy.

Laser ablation

Controlled laser energy heats and destroys the targeted prostate tissue. Temperature monitoring helps the surgeon assess treatment delivery and protect surrounding structures. More than one applicator position may be needed to cover the planned treatment zone.

The published phase II study reported a median treatment time of approximately 60 minutes, although the complete anaesthetic and theatre procedure may take longer.

Recovery

A urinary catheter may be required temporarily because prostate swelling can make urination difficult. Many patients can return home on the day of treatment or after a short admission, depending on their recovery and ability to pass urine.

What are the potential advantages?

The proposed advantages of ProFocal include:

Treatment directed at the known cancer rather than the whole prostate
No abdominal incision
A transperineal, minimally invasive approach
Short hospital stay
Faster initial recovery than major surgery
No ionising radiation
Preservation of untreated prostate tissue
A potentially lower risk of persistent urinary incontinence
A potentially lower risk of erectile dysfunction than whole-gland treatment
The possibility of further focal or whole-gland treatment if cancer remains or returns

These are potential benefits and should not be interpreted as guarantees.

What did the early ProFocal study find?

The first published phase II trial included 100 men with localised, MRI-visible Grade Group 2 or 3 prostate cancer.

At the three-month biopsy:

84% had no clinically significant Grade Group 2 or higher cancer within the treated area
Approximately 16% therefore had residual clinically significant cancer within the treatment zone
Erectile dysfunction was reported in 12%
The average sexual-function scores decreased by approximately 15%
Urinary-domain scores decreased by approximately 4.5%
No significant deterioration was reported in the other measured functional outcomes

These results are promising, but they represent very early follow-up. The study had no surgery, radiotherapy or active-surveillance control group. It therefore cannot establish whether ProFocal provides equivalent long-term protection against recurrence, metastasis or death from prostate cancer.

Possible side effects and complications

Short-term effects may include:

Bruising or discomfort in the perineum
Blood in the urine
Blood in the semen
Burning or discomfort when urinating
Urinary frequency or urgency
Temporary difficulty passing urine
Temporary catheterisation
Urinary tract infection
Pelvic or rectal discomfort
Fatigue following anaesthesia

Potential longer-term or less common problems include:

New or worsening erectile dysfunction
Reduced ejaculatory volume
Retrograde ejaculation
Urinary incontinence
Urethral or bladder-neck scarring
Persistent urinary symptoms
Damage to tissue outside the intended treatment zone
Infection or abscess
A fistula involving the urinary tract and rectum—expected to be rare
Incomplete cancer treatment
Cancer developing or becoming apparent elsewhere in the untreated prostate
A requirement for repeat focal therapy, radiotherapy or radical prostatectomy

The risk of sexual or urinary dysfunction depends partly on the size and location of the tumour. A lesion near the neurovascular bundles, urethra, urinary sphincter or bladder neck may be more difficult to treat without affecting function.

The untreated prostate remains important

Prostate cancer is frequently multifocal, meaning that separate areas of cancer may exist within the same prostate. MRI is very useful but cannot detect every small or biologically significant tumour.

ProFocal treats the selected target—not every prostate cell.

This creates two possible patterns of treatment failure:

In-field disease: cancer remains or returns inside the treated area.
Out-of-field disease: cancer is subsequently found elsewhere in the untreated prostate.

A successful early scan does not prove that all clinically significant cancer has been eliminated.

Follow-up after ProFocal therapy

Follow-up is more intensive than simply checking the PSA.

Because the prostate remains in place, PSA will not normally fall to an undetectable level. There is also no universally accepted PSA threshold that defines successful focal treatment or recurrence.

Follow-up may include:

Regular PSA testing
Clinical review and symptom assessment
Multiparametric MRI
Quality-of-life and erectile-function assessment
Repeat targeted biopsy of the treated area
Systematic biopsy of the untreated prostate
Additional imaging when recurrence is suspected

The Prostate Cancer Foundation of Australia cautions that PSA testing alone is not sufficient to exclude recurrent cancer after focal therapy. Patients must be willing to undergo long-term imaging and, when recommended, further prostate biopsies.

Can treatment be repeated?

Repeat focal treatment may be possible when residual or recurrent cancer remains localised and clearly targetable.

Depending on the findings, subsequent options may include:

Repeat focal ablation
Radical prostatectomy
External-beam radiotherapy
Another focal therapy technique
Active surveillance for selected low-volume disease
Systemic treatment if the cancer has spread

Salvage surgery or radiotherapy may still be possible after focal therapy, but treatment can sometimes be technically more complex because of scarring and tissue changes. The likely salvage options should therefore be discussed before proceeding with ProFocal.

Important limitations

Patients considering ProFocal should understand that:

ProFocal is not currently included on the Australian ARTG
It is not established as routine standard-of-care treatment
Published ProFocal evidence currently comes from a small number of men
The pivotal study was single-arm and had very short follow-up
Long-term rates of metastasis-free, cancer-specific and overall survival are unknown
There are no mature randomised comparisons with prostatectomy, radiotherapy or modern active surveillance
Approximately 16% of men in the initial study had clinically significant cancer remaining in the treated area at three months
Cancer may be missed elsewhere in the prostate
Repeat MRI scans and biopsies are required
Further cancer treatment may be needed
Access may be limited to trials or special regulatory pathways
Medicare or private health insurance may not cover treatment or follow-up costs

What do international urological guidelines say?

The European Association of Urology states that focal therapy has favourable functional outcomes, but definitive evidence of long-term oncological benefit remains unavailable. Its 2026 guideline recommends that focal HIFU or cryotherapy be undertaken within a prospective registry and that other ablative methods—including focal laser therapy—be offered only within a well-designed prospective clinical trial.

The American Urological Association and American Society for Radiation Oncology advise clinicians that comparative evidence for focal ablation is lacking and that patients must be informed that further treatment may be required. Focal or whole-gland ablation should not be offered for high-risk prostate cancer outside a clinical trial.

The Prostate Cancer Foundation of Australia similarly describes focal therapies as experimental and emphasises the need for continuing MRI, biopsies and careful long-term monitoring.

The bottom line

ProFocal is an exciting Australian-developed technology that may eventually provide selected men with a middle path between active surveillance and whole-gland treatment.

Its early results suggest that precisely delivered cooled laser therapy can destroy an MRI-visible prostate cancer target with relatively limited short-term urinary morbidity. However, early cancer clearance is not the same as proven long-term cancer control.

At present, ProFocal should be considered an investigational focal therapy, ideally undertaken within a properly governed clinical trial with multidisciplinary assessment, informed consent and mandatory long-term follow-up.

The decision should be made only after comparing ProFocal with all appropriate alternatives, including active surveillance, radical prostatectomy and radiotherapy.
