About this trial

This study is a phase III, open label, multicentre, three-group, randomised clinical trial. The primary aim of this study is to determine whether intensive groin ultrasound monitoring (1) is effective and safe to replace invasive groin lymph node dissection (LND) to manage vulvar cancer, (2) decreases the morbidity associated with vulvar cancer surgery, and (3) is cost effective.

Eligibility criteria

Willing and able to comply with all study requirements, timing and/or nature of required assessments.

Disqualifiers

Clinical or medical imaging evidence of regional and/or distant metastatic disease

Serious concomitant systemic disorders incompatible with the study (at the discretion of the investigator)
