Objectives: The incidence of depression after a late-stage cancer diagnosis is poorly understood and has not been the subject of intense investigation. We used population-based data to examine trends in postdiagnosis depression incidence among racial/ethnic and sexual groups.

Methods: We identified 123,066 patients diagnosed with late-stage breast, prostate, lung, or colorectal cancer from 2001 to 2013 in the Surveillance Epidemiology and End Results Medicare-linked database. The primary outcome was the incidence of postdiagnosis depression after a late-stage cancer diagnosis. Trend analysis was performed using the Cochran-Armitage test. Stratified incidence rates were calculated for the racial/ethnic and sexual groups.

Results: The incidence of depression after cancer diagnosis increased from 15.3% in 2001 to 24.1% in 2013, Ptrend<0.0001. About 50% of depression was reported in the first 3 months of stage IV cancer diagnosis. A total of 19,775 (20.0%) non-Hispanic whites, 1937 (15.9%) non-Hispanic blacks, and 657 (12.7%) Hispanics were diagnosed with depression during a mean follow-up of 2.7 months (interquartile range: 0.9 to 10.2 mo). The incidence of depression is significantly higher among females than males, 22.7% versus 16.3%, P<0.0001. In the multivariable logistic regression, non-Hispanic whites and females were still independent predictors of higher risk of postdiagnosis depression.

Conclusions: There are significant differences in the incidence of postdiagnosis depression among racial/ethnic and sexual groups in the United States. The consideration of racial/ethnic in depression prevention and diagnosis among cancer patients should be discussed as a matter of importance to ensure that there is no diagnosis bias among non-Hispanic blacks and Hispanics.
