Vulvar cancer breakthrough: surgery tailored by virus and gene status
NCT ID NCT05576831
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if matching the extent of surgery to the specific type of vulvar cancer (based on HPV infection and p53 gene changes) can reduce the chance of the cancer coming back. About 249 women with early-stage vulvar squamous cell carcinoma will take part. The goal is to move away from a one-size-fits-all approach and offer more personalized treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically confirmed primary diagnosis of vulvar squamous cell carcinoma * Surgically staged FIGO (International Federation of Gynaecology and Obstetrics) I-II disease * Margin status after primary surgery: * HPV-I VSCC: margins are negative for cancer but \<8mm, and/or positive for dVIN, and/or positive for p53 abnormality on IHC * HPV-A VSCC: margins are negative for cancer but \<8mm (regardless of in-situ (HSIL) margin status) * Age ≥18 years old * Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate. A similar process must be followed for sites outside of Canada as per their respective cooperative group's procedures. Exclusion Criteria: * Recurrent vulvar squamous cell carcinoma * Non-squamous cell carcinoma histotypes * FIGO stage III- IV disease * Patients referred for adjuvant radiation for close margins * Margins positive for cancer
