Regional skin cancer variation in Germany

Background:

Skin cancer is the most common cancer in Germany, characterized by an increasing prevalence. Excessive exposure to UV radiation is the main cause of the increasing frequency. So far, it is not clear which influence socio-demographic factors have on the development of skin cancer, beside UV radiation. The following study intended to analyse the effects of UV radiation and regional sociodemographic conditions on the prevalence of the malignant melanoma (MM) and non-melanocytic skin cancers (NMSC) in Germany. First results of this study will present here.

Methods:

Nationwide ambulatory account data (age standardised prevalences) from statutory health insured persons with MM and NMSC (2009 – 2015) were used. In addition, sociodemographic and satellite based UV- and solar radiation data were used. Descriptive as well as multivariate spatial statistical analysis were conducted on county level.

Results:

First results show an increasing prevalence for the observation period, but this does not affect all counties. Multivariate studies have shown a statistically significant correlation between prevalence and social indicators, particularly education and income. The higher income and education, the higher is the prevalence of MM and NMSC.

Conclusion:

The results show spatio-temporal dynamics in the prevalence of MM and NMSC in Germany. Sociodemographic indicators have been found as significant influencing factors. There is also an interrelation with regional UV radiation and sunshine hours. This is not contradictory to the results, but only proves the fact that individual (exposition-) behaviour is of great importance. Smaller spatial levels and a longer period of observation are necessary to make more detailed statements.
