391 Positive surgical margin is an independent predictor of overall survival of patients with vulvar squamous carcinoma

Background It is uncertain whether curative surgical treatment or a less radical surgery with adjuvant treatment should be provided to preserve function in patients with vulvar squamous cell carcinoma (SCC) that is adjacent to the urethra, anus, and vagina. The aim of this study was to investigate the surgical margin in patients with vulvar SCC with regard to local recurrence and overall survival. Methods Thirty-four patients were identified as having a diagnosis of vulvar SCC without distant metastasis. They had been treated surgically with curative intent at the Cancer Institute Hospital between May 1992 and January 2019. Clinical data were analyzed retrospectively. Results Rates of 5-year local recurrence-free survival among patients with positive, Conclusion To improve the prognosis, thorough resection with an adequate surgical margin is needed.
