Vulvar cancer breakthrough: one test could spare women unnecessary surgery
NCT ID NCT06358469
First seen Jun 27, 2026 · Last updated Aug 12, 2026 · Updated 4 times
Summary
This study is testing whether looking at two biological markers (HPV and p53) in early-stage vulvar cancer can help doctors decide the right amount of surgery. Some women may need less surgery, while others may need more. The study will follow 249 participants for 3 years to see how often the cancer comes back.
