Robots and dye could spare testicular cancer patients unnecessary treatment
NCT ID NCT06133543
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests a new, less invasive way to check if testicular cancer has spread. Doctors inject a dye into the testicle, then use a robot to find and remove the first lymph node that drains the tumor. The goal is to see if this method is accurate enough to replace more extensive treatments. The trial will enroll 44 adults with early-stage testicular cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Indocyanine green (ICG) dye
- What this could lead to
- If successful, this technique could become a new standard for staging testicular cancer, helping doctors avoid unnecessary treatments and their side effects.
- What could go wrong
- This is a small, early feasibility study with only 44 participants. The technique may not achieve the desired 90% sensitivity, and results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Clinically confirmed unequivocal testicular tumor by palpation and sonography with or without elevation of specific tumor markers AFP and/or ß-HCG. * Clinical exclusion of metastases in preoperative staging using contrast-enhanced CT of the thorax and abdomen. * The patient is of legal age. * The patient can communicate with the investigator without issues or limitations and can understand and sign the patient information and consent form without problems or limitations. Exclusion Criteria: * Testicular tumor with uncertain dignity * Patients with small testicular masses (\< 1 cm) * Patients with prior scrotal or retroperitoneal surgery for reasons other than a germ cell tumor. * The patient has received different chemotherapy. * The patient has undergone retroperitoneal radiotherapy. * Exclusion criteria for the use of ICG include a history of anaphylactic reactions to ICG and iodine intolerance (ICG solution contains sodium iodide). * The patient is in a reduced general condition or has a life-threatening illness. * The patient has a psychiatric illness.
