Cancer costs and outcomes for common cancer sites in the Finnish population between 2009-2014.

The changes in the cost components indicate that the length of stay has shortened in special care and treatment methods have developed towards outpatient care. This partially explains the decrease of costs. Also, at the same time outcomes improved, which indicates that decrease in costs did not come at the expense of treatment quality. As the survival rates increase, the relevance of mortality measures decreases and the relevance of other, patient-relevant outcome measures increases. In the future, the outcomes and costs of health care systems should be assessed routinely for the most common patient groups.
