The impact of severe mental illness on lung cancer mortality of patients with lung cancer in Finland in 1990-2013: a register-based cohort study

摘要

Background: Although the link between severe mental illness (SMI) and elevated cancer mortality is well established, few studies have examined lung cancer survival and SMI in detail. Our study compared cancer-specific mortality in patients with lung cancer with and without a history of SMI and analysed whether mortality differences could be explained by cancer stage at presentation, comorbidity or differences in cancer treatment.
