Cutaneous melanoma in childhood and adolescence.

Using population-based data from the Surveillance Epidemiology and End Results Program of the National Cancer Institute, melanoma occurring during childhood was evaluated. Compared to adult cases of melanoma, childhood cases had a higher proportion of females (61%) and non-Caucasians (6.5%). The incidence of melanoma increased 85% among 15- to 19-year-olds from 1973 to 1996. Incidence for 15- to 19-year-olds was higher in southern (23.9/million) than northern registries (14.5/million). Non-Caucasians had 3-30% of the cases expected compared to Caucasians. Overall survival of children/adolescents with melanoma was 89% and 79% at 5 and 20 years postdiagnosis, respectively. The majority of deaths were directly attributed to melanoma (72%).
