BACKGROUND: Melanoma of the vulva is the second most common vulvar cancer after epidermoide carcinoma. Patients with the disease usually present with a late stage disease with a poor prognosis. The prognostic factors reported in previous studies are not homogeneous and it is no clear the clinical or pathogenic role of c-KIT expression this neoplasm. Breslow staging currently is the most accurate predictor factor.
METHODS: We performed a clinicopathological study with literature review to identify predictors of prognosis and survival in melanoma of the vulva and investigated the expression of c-KIT (by immunohistochemistry) in 10 patients from the Instituto Nacional de Cancerología (Mexico City, Mexico).
RESULTS: Ten patients were identified, all older women with delayed presentation, high stage disease and limited response to treatment. We identified 5 patients (50%) with c-KIT expression, four of them recurred (p=0.01) and ultimately 3 died (p=0.038). We identified a) Satellitosis and b) c-KIT expression as prognostic predictors for death.
CONCLUSIONS: We conclude that c-KIT expression is a valuable predictor of prognosis and survival, especially in tick (> 4 mm) melanoma.
