Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Background: The latest global melanoma disease burden and changes are rarely reported, which is important for developing potential strategies to reduce the melanoma-related burden. The aim of this study was to examine the variations and trends in the burden of melanoma between 1990 and 2019.
Methods: We extracted detailed data about melanoma from the 2019 Global Burden of Disease study in 204 countries and territories. Detailed data includes the number of melanoma incident cases, deaths, DALYs, and age-standardized rates. We calculated the estimated annual percentage change (EAPC) to quantify the temporal trends of the age-standardized rates of melanoma, and analyzed the influential factors of EAPCs by Spearman correlation.
Findings: From 1990 to 2019, the incidence of melanoma cases increased by 170% to 289 950, death increased by 90% to 62 840, and DALYs increased by 67% to 1 707 800 globally. The age-standardized incidence rate (ASIR) of melanoma increased globally by an average of 1 · 13 (95% CI, 0·93-1·32) while the ASRs of mortality and DALYs both declined with the EAPC of -0·27(95% CI, -0·36 to -0·19) and -0·49(95% CI, -0·57 to -0·41), respectively. In 2019, the highest burden of melanoma was observed in high SDI regions , especially Australasia (ASIR=43·36/100 000) and High-income North America regions (ASIR=16·62/100 000). The increasing trend in ASIR was observed in most countries (159/204) , with the highest increase in South Korea, followed by Belarus and Guatemala. However, decreasing or stable trends in ASRs of mortality and DALYs were detected in almost half of countries (102/204; 117/204) except for the low-middle SDI regions such as Guatemala.
Interpretation: The variations and trends of melanoma burde n differed greatly across the world. Albeit the overall ASRs of mortality and DALYs declined, the ASIR of melanoma incrementally rose in most countries, which implies more targeted strategies should be taken for areas and groups with relatively higher burden.
