A retrospective study including 55 cutaneous melanoma patients with 9.5 years follow-up was carried out to assess the significance of various prognostic factors. The histological samples were evaluated according to Clark's and Breslow's classifications and six nuclear features were measured by interactive morphometry. Mitotic activity was assessed by two different methods: mitotic activity index (MAI) and volume corrected mitotic index (M/V index). The overall disease-related five-year survival of patients was 76.4%. TNM stage (p = 0.0001), sex (p = 0.0024), M/V index (p = 0.003), standard deviation of nuclear form factor (p = 0.023), MAI (p = 0.02), shortest nuclear axis (p = 0.023) and Breslow's classification (p = 0.044) predicted survival in univariate analysis. A multivariate analysis including clinical, histological and morphometric features pointed the Clark's classification as the most important predictor of survival (p = 0.002), while the other variables included had no independent prognostic value. The prognostic importance of mitotic indices and morphometric features is clearly a subject for further studies in superficial melanomas.
