What this Trial Is About
Researchers are evaluating a new technique called LaserSAFE to detect cancer at the edges of the prostate during surgery for prostate cancer. The study focuses on whether LaserSAFE can help surgeons decide if it is safe to preserve the nerves around the prostate, especially in patients usually not considered for nerve-sparing surgery. The study also examines how quickly and reliably LaserSAFE provides this information during the operation. The LaserSAFE technique uses a special fluorescence confocal microscope to scan the removed prostate tissue in the operating room within about five minutes. The prostate is prepared by cleaning, staining with a special solution, rinsing, and then scanned on both sides. Trained pathologists interpret the images to identify any cancer at the surgical margins and communicate results during surgery. If cancer is detected beyond certain limits, additional tissue including nerves may be removed. Participants will complete quality of life questionnaires before surgery and at 3 and 12 months after. They will undergo standard robot-assisted prostate surgery with nerve-sparing attempted initially, with LaserSAFE guiding any further tissue removal. Routine follow-up visits will be part of standard care. Researchers will measure outcomes including the accuracy of LaserSAFE in detecting positive margins, cancer rates after surgery, urinary incontinence, and erectile function over 12 months.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Patients diagnosed with clinically significant operable cT2-T3a N0 M0 prostate cancer.
- Medically fit to undergo robot-assisted radical prostatectomy.
- Scheduled for robot-assisted prostate surgery with recommendation against nerve sparing on at least one side based on clinical and imaging assessments.
- Able to read English and give informed consent.
You will not qualify if you...
- Patients who received neo-adjuvant androgen deprivation therapy.
- MRI indicates very low likelihood of cancer spread near nerves (EPE Likert 1 score or tumor away from posterolateral prostate areas).
- MRI indicates high likelihood of cancer spread near nerves (Likert 5 score or bulging tumor on MRI T2 images).
- Preoperative imaging shows rectal involvement or seminal vesicle invasion where nerve sparing is unsafe.
- Patients previously treated for prostate cancer with radiotherapy, brachytherapy, focal therapy, or chemotherapy.

1 visit (in-person)
Duration - Day of surgery
Participants undergo confocal microscopy imaging during their radical prostatectomy to assess surgical margins in real-time.
1 visit (in-person, during surgery)
Duration - 12 months
Participants are monitored for up to 12 months after surgery to assess clinical outcomes such as positive margin rates, biochemical failure, and functional scores.
