[Clinical characteristics of melanoma metastasis]

Approximately one third of clinical Stage I melanoma patients will experience disease recurrence. The author reviews the main prognostic factors predicting the outcome of melanoma patients, the incidence, pattern and time of first metastases. Of all recurrences, two third will occur earlier by the lymphatic, and one third later by the hematogenous pathway. 75-80% of recurrences develop in the first 3 years, 3-4% of metastases occur after 10 years of disease-free interval. The data emphasize the value of lifelong follow-up.
