Description of intervention(s) / exposure
In this study, we propose to evaluate the feasibility of a novel, thermal therapy and feedback system (ProFocal­Rx Laser Thermal Therapy System) for the treatment of biopsy confirmed and MR­ visible prostate cancers. The system’s real­time measurement system provides information on the thermal dose delivered to the target, resulting in a more precise and controlled delivery which has not been possible to date with other ablative therapies.
MR / ­US guided focal laser ablation will be performed using the ProFocal­-Rx Thermal Therapy System. The treatment require a general anaesthetic and approximate treatment time of under 1 hour. The Urologist will be performing the treatment. This system comprises a surgical diode laser, a fiberoptic laser applicator with diffusing tip and temperature feedback monitoring system.Focal targeted laser therapy for treating localised prostate cancer in men. The actual lasering of the tumour will take 10-20 minutes. Men 50 years and older who have been diagnosed with a positive MRI and intermediate risk prostate cancer will be eligible. They will undergo a general anaesthetic and MRI - US fusion targeted treatment of their prostate cancer in an outpatient setting. Immediate post treatment MRI will determine the extent of the laser ablation and a follow up targeted biopsy of the prostate in 6 weeks will confirm the success of the outcome of focal laser therapy.

Outcomes
Primary outcome [1] 307070 0
Absence of any residual cancer in the targeted area from laser ablation.
Timepoint [1] 307070 0
MRI following treatment to assess the treatment effect. The MRI allows for immediate treatment effect to be measured after focal laser ablation.
On going assessment of the prostate gland will also be performed with annual MRI scans to assess the whole and treated prostate site.
Secondary outcome [1] 350544 0
Following the focal ablation of the prostate tumour a MRI scan of the prostate will be performed to assess the ablation effect on the tumour site. Also the tumour will be assess by performing a biopsy of the prostate six weeks after the focal therapy was performed. This will be used to assess the absence or presence of tumour.
Timepoint [1] 350544 0
6 weeks post treatment a targeted and template biopsy of the prostate is performed to assess this.
Secondary outcome [2] 352582 0
No de novo cancer in the remainder ( non treated areas ) of the prostate to be evaluated
Timepoint [2] 352582 0
MRI scan immediately post treatment
6 weeks post treatment - prostate biopsy
PSA blood tests and questionnaires at 6 monthly intervals
Prostate MRI scan yearly
This will be done for a total of 5 years

Statistical methods / analysis
The profile and the number of projected participants (100) are appropriate to answer the research question of this pilot study. A similar study was recently performed to assess the safety and efficacy of focal laser therapy at Macquarie University Hospital to answer this question.
The recruitment strategy is fair with clear outline of inclusion and exclusion criteria. Patients are fully informed of the procedure before written consent is obtained.

Summary
Brief summary
The purpose of this study is to evaluate the feasibility of a new laser therapy system (called ProFocal­-Rx Laser Therapy System) for the treatment of certain prostate cancers.

Who is it for?
You may be eligible for this study if you are aged 50 or older and have a diagnosis of prostate cancer.

Study details
All participants in this study will undergo a general anaesthetic and targeted treatment (called ‘ablation’) of their prostate cancer in an outpatient setting. Immediate following the procedure, an MRI scan will be performed to determine the extent of the laser ablation. Six weeks after the procedure participants will have a targeted biopsy of the prostate to assess the outcome of the laser therapy.

It is hoped this research will demonstrate the feasibility of this technology to treat prostate tumours, reduce discomfort and improve patients quality of life.
