Faster Histolog confocal scanning for checking prostatectomy margins

Feasibility of Timesaving When Using Histolog Confocal Laser Endomicroscopy for Margin Assessment in Prostatectomy Specimen

Not applicable Interventional Icahn School of Medicine at Mount Sinai · NCT07141121

The Histolog Scanner will be tried during robot-assisted radical prostatectomy to see if it can quickly and safely spot cancer at the prostate edge in patients with intermediate or high-risk prostate cancer.

What this trial studies

This feasibility study uses the Histolog Scanner, an ultra-fast confocal microscope, to image the surface of fresh prostate specimens during robot-assisted radical prostatectomy and compare the time burden to traditional NeuroSafe margin assessment. Surgeons will use the device intraoperatively to guide margin decisions while investigators record time, workflow impact, and margin integrity. The protocol includes an economic analysis using U.S. market prices to estimate potential cost and time savings in the American clinical setting. Results will inform whether a larger clinical trial is warranted to adopt this approach for routine intraoperative margin evaluation.

Who should consider this trial

Good fit: Ideal candidates are adults (≥18) with treatment-naive, localized or locally advanced D'Amico intermediate or high-risk prostate cancer who are scheduled for robot-assisted radical prostatectomy and can give informed consent.

Not a fit: Patients with low-risk disease, prior pelvic radiation, prior androgen-deprivation or other hormonal/focal prostate treatments are excluded and are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this approach could shorten intraoperative margin checks and help surgeons preserve nerves without adding time or cost to surgery.

How similar studies have performed: Confocal imaging for margin assessment is an emerging approach and the Histolog Scanner is recently FDA-cleared with early promising reports, but robust U.S. data on time and cost savings are limited.
