Could a simple injection replace major surgery for ovarian cancer staging?
NCT ID NCT06963268
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a sentinel lymph node technique, where a small amount of radioactive tracer and dye is injected to find the first lymph nodes that might contain cancer. In 200 women with early-stage ovarian cancer, doctors will compare this method to the standard approach of removing many lymph nodes. The goal is to see if the less invasive technique is accurate enough to replace the more extensive surgery, which could mean fewer side effects and faster recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sentinel lymph node technique (radioactive tracer and dye injection)
- What this could lead to
- If successful, this technique could replace extensive lymph node removal, reducing surgical complications and recovery time for early-stage ovarian cancer patients.
- What could go wrong
- This is a Phase 3 trial, but the technique may not be accurate enough to replace standard surgery, and there is a risk of missing cancer spread.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Signed informed consent prior to the performance of any procedure related to the clinical trial. * Female, 18 years of age or older at the time of inclusion. * Patients with a histopathological diagnosis of malignant ovarian tumor in a deferred study (any epithelial histology), in apparent early stage FIGO I-II, proposed for staging surgery, or patients with suspected malignant ovarian tumor in apparent early stage FIGO I-II, who will undergo exploratory laparotomy and operative biopsy, and if positive, will undergo staging surgery. Exclusion Criteria: * Failure to obtain informed consent or revocation of informed consent. * Under 18 years of age at the time of inclusion. * Previous history of vascular surgery on the aorta, vena cava, or pelvic vessels. * Previous pelvic or paraaortic lymphatic surgery. * Previous lymphoma. * Previous abdomino-pelvic tumor. * Previous allergy to Tc99 or ICG. * Pregnancy/Breastfeeding. Patients who have signed informed consent but do not meet all inclusion criteria and none of the exclusion criteria will be considered as selection failures.
