Spatial disparities in melanoma incidence and prognosis with consideration to stage at diagnosis, gender and marital status

Publication date: Available online 22 July 2016 Source:Spatial and Spatio-temporal Epidemiology Author(s): Ulf Strömberg, Anders Holmén, Stefan Peterson Screening strategies need to consider differences in late-stage disease detection linked to socio-demographic and geographic factors. We specifically addressed disparity in melanoma stage at diagnosis linked to residential municipality, gender and marital status within the middle- and old-age population of southern and western Sweden. Population-based registers were used to identify the melanoma cases diagnosed in 2004–2013 (n =7,417). Disease mapping for each population group based on gender and marital status showed marked spatial disparities in melanoma incidences and the overall patterns differed by stage at diagnosis. The incidence of early-stage melanoma was markedly higher in the western region, whereas the incidence of late-stage melanoma was markedly higher in the southern region except for married women. Excess mortality among cases was observed to be higher in the southern than in the western region, with significant regional differences for the married male cases and the unmarried female cases.
