Depression among elderly cancer patients

Introduction Depression is one of the most common mental illnesses in the elderly and its consequences are severe. Aims To measure the prevalence of depression in elderly cancer patients and subsequently determine the sociodemographic and clinical factors correlated with this disorder. Methods We conducted a descriptive and analytical cross-sectional study of patients aged over than 65 years old, suffering from cancer and who had no cognitive impairment, admitted in 2013 in the Oncology and palliative care unit of Gabes regional Hospital (Tunisia). We used a self-rating questionnaire to detect sociodemographics and clinical variables, the Geriatric depression scale (GDS) to assess depressive symptoms, and the Activity of Daily Living to determine the degree of autonomy. Results At the end of our investigation, we included 60 patients. The prevalence of depression was 48%. Depression was significantly correlated with: marital status (widower subjects were more depressed (74% vs. 34%, P  = 0.007)), less degree of autonomy (80% vs. 38%, P  = 0.04), fatigue (62% vs. 26%, P  = 0.007), pain (59% vs. 26%, P  = 0.02), family psychiatric history (80% vs. 20%, P  = 0.02), family history of death by cancer (72% vs. 38%, P  = 0.01), WHO condition (67% vs. 34%, P  = 0.04) and the presence of co morbidity in particularly diabetes (69% vs. 41%, P  = 0.05). Conclusion Depression is prevalent in oncogeriatric environments. This could compromise quality of support and care of these patients. Close collaboration between oncologist and psychiatrist is needed to support and relieve these patients.
