RESUMEN
PURPOSE: Individuals with Common Mental Disorders (CMDs) may have a higher cancer mortality. The purpose of this study was to examine cancer-related mortality among patients with CMDs and verify which cancer types are predominantly involved. METHODS: We used the Regional Mental Health Registry of the Emilia-Romagna region, in Northern Italy to identify patients aged ≥ 18 years who received an ICD 9-CM diagnosis of CMDs (i.e., depressive and neurotic disorders) over a 10 year period (2008-2017). Information on cause of death was retrieved from the Regional Cause of Death Registry. Comparisons were made with data from the regional population without CMDs. RESULTS: Among 101,487 patients suffering from CMDs (55.7% depression; 44.3% neurotic disorders), 3,087 (37.8%) died from neoplasms. The total standardized mortality ratio (SMR) was 1.82 (95% CI 1.78-1.86) while the SMR for all neoplasms was 2.08 (95% CI 2.01-2.16). Individuals of both genders, with both depressive and neurotic disorders had a higher risk of death from almost all cancers compared with the regional population. CONCLUSION: Patients with CMDs have considerably higher cancer mortality risk than the general population. Higher mortality was observed for a broad range of cancers associated with different aetiologies. It is imperative to promote cancer awareness, prevention and treatment for people with CMDs.
