Device for detecting leftover prostate cancer tissue during surgery

Microendoscopic Electrical Impedance Sensing for Real-time Intraoperative Surgical Margin Assessment

Observational Dartmouth-Hitchcock Medical Center · NCT06039085

This study is testing a special device to see if it can help doctors find leftover prostate cancer tissue during surgery to improve outcomes for men with prostate cancer.

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).

Who should consider this trial

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

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

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 performed: 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.
