New surgical technique aims to reduce cancer margins in vulvar dysplasia
NCT ID NCT05934851
First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 2 times
Summary
This study tests whether a surgery that uses frozen sections to guide removal (Frozen-Section Directed Excision) works better than the usual wide local excision for high-grade vulvar dysplasia. About 112 adults with confirmed high-grade dysplasia will be randomly assigned to one of the two surgeries. The main goal is to see which method leads to fewer positive margins (cancer cells left behind) and lower recurrence at 6 months.

Inclusion Criteria: 1. Written informed consent and HIPAA authorization for release of personal health information. 2. Age ≥ 18 years at the time of consent 3. Histological or cytological confirmation of VIN 2, VIN 3, VIN 2/3 or High-grade Dysplasia NOS with a planned excisional procedure, with high suspicion by the enrolling investigator that gross surgical margins of ≥ 3 mm can be achieved without laser or other destructive procedures 4. Surgery is expected to occur within 90 days from randomization 5. Ability to read and understand the English and/or Spanish language 6. As determined by the enrolling physician, ability and willingness of the subject to comply with study procedures for the entire length of the study 7. No known pregnancy Exclusion Criteria: 1. Excision is not possible due to anatomy (proximity to urethra/clitoris) 2. Known immunodeficiency syndrome 3.
