Melanoma is an aggressive form of skin cancer, and a worldwide problem with increasing incidence. Little is known about the burden of melanoma in the Chinese population. We evaluated temporal trends and geographic variation in melanoma-associated burden, to narrow an important knowledge gap concerning the consequences of this disorder across time, provinces in China. After the general analytic strategy used in the 2017 Global Burden of Disease study, we analyzed the incidence, mortality, prevalence and disability-adjusted life-years (DALYs) of melanoma, by age, sex and geography from 1990 to 2017. Levels in melanoma burden were assessed for 33 province-level administrative units between 1990 and 2017. We used joinpoint regression analysis to estimate the slope of incidence and mortality trends. The age-standardized incidence rate of melanoma was 0.9 per 100,000 in 2017, with a 110.3% rise compared to 1990. Although the age-standardized DALYs rate (per 100,000) decreased from 9.1 in 1990 to 7.6 in 2017, it showed an upward trend from 2007 to 2017. The DALYs rate increased steadily with age for females while increased and peaked at 55-59 years for males. The incidence of melanoma was higher in the clustered eastern provinces than western provinces, while the DALYs showed a pattern in opposite direction. In China, there has been a substantial increase in the burden of melanoma over the last decade, representing an ongoing challenge in Chinese population. More targeted strategies should be developed for elderly population, especially for females, to reduce the melanoma burden throughout China, particularly the western provinces.
