Four-Week Prevalence of Mental Disorders in Patients With Cancer Across Major Tumor Entities
Menée en Allemagne auprès de 2 141 patients atteints de cancer, cette étude analyse, sur une durée de quatre semaines, la prévalence de troubles psychiques en fonction du type de cancer (sein, tête et cou, pancréas, estomac et œsophage)
Purpose : To provide the 4-week prevalence estimates of mental disorders in cancer populations. Patients and Methods: We enrolled adult patients with cancer from in- and outpatient care facilities, using a proportional stratified random sample based on the nationwide cancer incidence in Germany. Patients who scored 9 or above on the Patient Health Questionnaire (PHQ-9) were administered to the standardized computer-assisted Composite International Diagnostic Interview for mental disorders adapted for cancer patients (CIDI-O). A random sample of those with a PHQ-9 score that was less than 9 were selected for a CIDI-O. Results : A total of 5,889 patients were identified, which led to 4,020 participants (a 68.3% response rate); of those, 2,141 patients were interviewed. The 4-week total prevalence for any mental disorder was 31.8% (95% CI, 29.8% to 33.8%); this included any anxiety disorder (11.5%; 95% CI, 10.2% to 12.9%), any adjustment disorder (11.1%; 95% CI, 9.7% to 12.4%), any mood disorder (6.5%; 95% CI, 5.5% to 7.5%), any somatoform/conversion disorder (5.3%; 95% CI, 4.3% to 6.2%), nicotine dependence (4.5%; 95% CI, 3.6% to 5.4%), alcohol abuse/dependence (0.3%; 95% CI, 0.1% to 0.6%), any mental disorder resulting from general medical condition (2.3%; 95% CI, 1.7% to 2.9%), and any eating disorder (0%). The highest prevalence for any mental disorder was found in patients with breast cancer (41.6%; 95% CI, 36.8% to 46.4%), followed by patients with head and neck cancer (40.8%; 95% CI, 28.5% to 53.0%). The lowest prevalence was found in patients with pancreatic cancer (20.3%; 95% CI, 8.9% to 31.6%) and stomach/esophagus cancers (21.2%; 95% CI, 12.8% to 29.6%). Conclusion : Our findings provide evidence for the strong need for psycho-oncological interventions.
