Popis: Background : The prognostic factors of cutaneous melanoma reported in Japan were different from those in US and Europe in evaluating the prognostic values of the biopsy types, sex, anatomic location and so on. The aim of this study was to identify the prognostic factors for survival in cutaneous melanoma in Japan by performing univariate and multivariate analyses. / Methods : We studied a total of 103 patients with cutaneous melanoma, treated in Osaka City University Hospital during the period 1991-2003. Eleven factors were evaluated by uni- and multivariate analyses. Kaplan-Meier analyses were performed to estimate and compare five-year survival rates. After checking for independence, prognostic factors were then evaluated applying a Cox proportional hazards model in localized melanoma patients and in all invasive melanoma patients....
