Robot-assisted biopsy for testicular cancer

Official title: RAISN - Robot-assisted ICG-guided Sentinel Node Biopsy in Testicular Cancer

Run by Heinrich-Heine University, Duesseldorf · NCT06133543 · Data updated 2026-11-12

This study is testing a new robot-assisted method for taking biopsies in men with testicular cancer to see if it can more accurately find hidden cancer and reduce unnecessary treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with clinically confirmed testicular tumors and no evidence of metastases.

Probably not a fit

Patients with uncertain tumor dignity or those who have undergone prior surgeries for reasons other than germ cell tumors may not benefit from this study.

What this trial studies

This clinical trial investigates a novel technique called robot-assisted image-guided sentinel lymph node biopsy (RAISN) for patients with testicular cancer. The approach aims to improve the accuracy of diagnosing occult metastatic disease in clinical stage I testicular cancer, potentially reducing unnecessary treatments and associated toxicities. By utilizing indocyanine green (ICG) for imaging, this minimally invasive procedure could change the management of newly diagnosed patients. The study will assess the feasibility and effectiveness of this technique compared to traditional methods.

Why it matters

Potential benefit: If successful, this technique could lead to more accurate diagnoses and reduced overtreatment for testicular cancer patients.

How similar studies have gone: While few studies have explored sentinel lymph node diagnostics in testicular cancer, the use of similar robotic and imaging techniques has shown promise in other cancers.
