Background: The incidence of cutaneous melanoma has risen faster than almost any other type of cancer in the last 50 years. Ultraviolet (UV) radiation and genetic susceptibility are the most important risk factors.
Objective: We aimed to determine the epidemiologic indicators of melanoma in Hungary, a country with an estimated population of 9.8 million and an area of 93 030 km2.
Methods: Anonymized patient records from the National Health Insurance Fund Management covering the entire population were used to determine the incidence and prevalence of melanoma in the counties of Hungary from 2013 to 2017. Altogether 20 030 melanoma cases were identified for inclusion in this study.
Results: The prevalence of melanoma increased over the investigated period and was significantly higher among women than men. The incidence of melanoma stagnated during this period and the incidence rate was the highest among the elderly. Interestingly, the incidence was higher in males in the elderly population, while the incidence was higher in females in the younger (<60 years) population. Geographical variations in ambient UV radiation did not show statistically significant correlation with the regional variability of epidemiologic indicators, probably due to small differences in the number of bright sunshine hours per year between regions. Although Hungary is a relatively small country, we observed regional heterogeneity in socioeconomic factors. Notably, a significant and strong negative correlation was found between single-person household rates and melanoma prevalence.
Conclusion: In addition to ambient UV radiation, melanoma incidence and prevalence appear to be related to age, gender and socioeconomic factors.
