Is this trial a fit for you?

Likely a good fit

Ideal candidates are men aged 18 and older with a clinical diagnosis of prostate cancer requiring robotic-assisted radical prostatectomy (RARP).

Probably not a fit

Patients with implanted electrical devices, such as pacemakers, or those with impaired decision-making capacity may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This research involves a custom Electrical Impedance Imaging (EII) probe designed to assess whether any prostate cancer tissue remains after prostate removal. Two hundred men diagnosed with prostate cancer will participate, providing data from both in vivo and ex vivo assessments during and after surgery. The study will also monitor any post-surgical complications related to the use of the EII device and evaluate its feasibility for clinical integration. The goal is to improve surgical outcomes by accurately identifying Positive Surgical Margins (PSMs).

Why it matters

Potential benefit: If successful, this device could significantly reduce the likelihood of cancer recurrence by ensuring complete removal of prostate cancer tissue.

How similar studies have gone: While the approach of using electrical impedance for surgical margin assessment is innovative, similar studies have shown promise in related fields, indicating potential for success.
