Real-life data on health care costs and loss of productivity after implementing new agents for metastatic melanoma are important to supplement model-based economic data. All patients registered in the Danish Metastatic Melanoma Database (DAMMED) and the National Patient Registry in 2007-2011 were compared to 2012-2016 after the implementation of checkpoint inhibitors and targeted therapy. Health care costs, social transfer income (STI), and loss of productivity were calculated with a 2-step one model generalised linear regression (GLM) model. Medicine costs were calculated separately. In 2007-2011, 70 (15%) out of 464 patients were long-term survivors compared to 347 (32%) out of 1089 patients in 2012-2016. Total health care costs per patient year were significantly lower in the first treatment year (€41.457 versus €60.547, relative change (RC) 0.72, 95% confidence interval (CI) 0.56-0.94, p = 0.015) and without significant difference the second year in 2012-2016 compared to 2007-2011. Medicine costs per patient year increased the first (€85.464 versus €26.339, RC 3.39, 95% CI 2.61-4.41, p < 0.001) and the second (€26.464 versus €11.150, RC 2.59, 95% CI 1.98-3.40, p < 0.001) year in 2012-2016 compared to 2007-2011. Productivity increased for long-term survivors in 2012-2016 in contrast to 2007-2011. Implementation of targeted therapy and checkpoint-inhibitors has increased medicine costs more than three-fold for long-term survivors. Total health care costs excluding medicine costs were significantly lower for long-term survivors the first and without change the second treatment year in 2012-2016 compared to 2007-2011. However, the number of treated patients increased which leads to an increase in overall total health care costs. Importantly, productivity increased for long-term survivors in 2012-2016.
