RESUMO
Chile has a medium-to-high skin cancer mortality rate. Previous studies have shown an increasing rate of skin cancer mortality. We evaluated skin cancer mortality characteristics and their temporal evolution in Chile from 1990 to 2005 in a mixed ecological study using death certificate databases. Age, sex, year and region of residence were obtained for melanoma and non-melanoma deaths. Crude and age-sex-adjusted rates were calculated using the national projections and WHO 2000 standard population data. Descriptive and temporal analyses, using a Prais-Winsten regression, were computed. A total of 3588 deaths were registered, of which 55% were melanoma and 54% occurred in men (median age 71 years; women were older). The adjusted rate was 1.75 deaths per 100,000 inhabitants (2.22 in men vs. 1.39 in women). Melanoma skin cancer and non-melanoma skin cancer mortality had a tendency to increase. In conclusion, skin cancer mortality is rising beyond the rate predicted by ageing. An increased incidence due to changes in modifiable factors, such as exposure to ultraviolet radiation and arsenic, might explain the increase in skin cancer mortality.
