Abstract

OBJECTIVES:

To evaluate various treatment modalities for vulvar intraepithelial neoplasia (VIN) in relation to possible risk factors for recurrence.

METHODS:

Retrospective review of 93 patients with VIN treated by CO(2) laser vaporization, photodynamic therapy with aminolevulinic acid (PDT), excision or vulvectomy.

RESULTS:

40.4% of the 47 patients with laser vaporization, 48.1% of 27 patients with PDT, 42% of 12 patients with local excision and none of the 7 patients treated by vulvectomy experienced a relapse within a mean follow-up of 53.7 months. The risk for recurrence significantly increased with VIN grade (P = 0.02), multifocal VIN disease (P = 0.01), multicentric intraepithelial neoplasia (P = 0.05) and high-risk HPV infection (P < 0.001). In multivariate analysis, only HPV status remained significant (P = 0.012) and, if HPV testing is not available, multifocality (P = 0.03). The lowest rate of postoperative side effects was noted in patients after PDT. There was one (1%) case of progression to vulvar cancer.

CONCLUSIONS:

Vulva preserving treatment methods for VIN have high recurrence rates, especially in patients with HPV infection and multifocal disease. Therefore, careful long-term surveillance is mandatory.
