Spots Global Cancer Trial Database for Study to Evaluate a New Method to Detect Residual Tumours During Surgery for Prostate Cancer Using Confocal Microscopy

Study Description

Brief Summary: Prostate cancer is the most common solid cancer affecting male patients worldwide. When diagnosed early, it can usually be cured with surgery (radical prostatectomy), but this procedure is associated with side effects such as urinary incontinence and erectile dysfunction. If the nerves that surround the prostate are left intact (nerve-sparing), the risk of developing these side effects decreases. However, since these nerves are in intimate contact with the prostate there is a chance of leaving cancer cells behind, with the subsequent need for additional treatments. Sadly, the current methods surgeons use to select patients who can safely be offered nerve-sparing are not very accurate in predicting where the tumour is extending outside the prostate. NeuroSAFE is a technique that can inform the surgeon if there are tumour cells on the surface of the prostate and indicate the need for removing more tissue during the same operation. However, it requires a specialised team to process the sample in a reasonable amount of time that does not excessively prolong the surgery. Therefore, many centres are not able to perform it. A new technology called fluorescence confocal microscopy (LaserSAFE) can be used to examine the surface of the prostate and can identify when cancer is present. Critically, it requires minimal training and resources to produce results in a few minutes and the microscope can be placed in the operating room. The investigators aim to recruit a group of 20 patients who will undergo radical prostatectomy as a treatment for prostate cancer. The prostate specimen will be analysed using both techniques, but decisions on how much tissue to resect during surgery will depend on the results of NeuroSAFE. This feasibility study will allow us to understand the challenges associated with performing both techniques. This will allow us to plan a larger study to evaluate the accuracy of LaserSAFE.

Detailed Description: This trial will be a multi-site, single-blinded, prospective, feasibility study. 20 participants will be recruited from 2 centres that have experience performing the NeuroSAFE technique. Participants will undergo a robotic-assisted radical prostatectomy with nerve-sparing guided by the NeuroSAFE technique. Before the prostate is sent for evaluation the LaserSAFE technique will be used to analyse the corresponding posterolateral surfaces of the prostate. Participating pathologists involved in interpreting the results of NeuroSAFE will be blinded to the LaserSAFE results, to avoid influencing standard patient treatment, management, and progression outcomes after radical prostatectomy.
