A population-based registry study on relative survival from melanoma in Germany stratified by tumor thickness for each histological subtype

Melanoma relative survival varies by histology. However, differences were strongly alleviated after adjustment for tumor thickness. Increased 5-year relative survival between the periods 2002-2005 and 2010-2013 is explained by a decrease in tumor thickness. Prevention and awareness should be encouraged as prognosis of thick melanoma is still poor.
