Prognostic impact of reduced tumor-free margin distance on long-term survival in FIGO stage IB/II vulvar squamous cell carcinoma.

FIGO stage IB/II VSCC patients' prognosis is affected by margin distance. Long-term survival is significantly reduced in patients with tumor-free margins <5 mm, even in the absence of lymph node metastasis. Thus, these patients should be offered further surgical or adjuvant treatment.
