Could a single dye replace the standard two-step test for vulvar cancer spread?
NCT ID NCT06039111
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares a dye called ICG alone against the standard two-method approach (ICG plus a radioactive tracer) to find cancer in lymph nodes of women with early vulvar cancer. About 58 women will take part. If ICG alone works just as well, it could simplify surgery and reduce radiation exposure.
