Abstract:
244 Background: Risk of suicide is increased after cancer diagnosis. Our study aims to investigate the racial differences on risk of suicide after cancer diagnosis in a nationwide cohort of U.S. patients. Methods: Patients ≥ 18 years and diagnosed with breast (n = 616,099; 26.4%), lung (n = 585,978; 25.0%), colorectal (n = 429,060; 18.4%), or prostate cancer (n = 705,812; 30.2%) from 1988-2010 in Surveillance, Epidemiology and End Results Program (SEER) were identified. A Cox-proportional hazard model was used to compare the suicide mortality of the races (Hispanic white, African American, Asian/Pacific Islander, American Indian/Alaska Native) to non-Hispanic white patients adjusting for age, sex, marital status, household income, education level and cancer sites. Results: A total of 2,336,949 patients were identified, and there were 3,406 suicide death events. Fifty percent of suicide deaths were within 32 months after cancer diagnosis (interquartile range: 66 months). After a median follow-up of 49 months, the suicide mortality was lower in African American (HR: 0.29, 95% CI: 0.25-0.35, p value 〈 .0001), Hispanic white (HR: 0.49, 95% CI: 0.41-0.58, p value 〈 .0001), Asian/Pacific Islander (HR: 0.67, 95% CI: 0.57-0.79, p value 〈 .0001). The suicide mortality was the same comparing American Indian/Alaska Native to non-Hispanic white patients (HR: 1.01, 95% CI: 0.62-1.65, p value: 0.97). Conclusions: After adjusting for sociodemographic factors, non-Hispanic white cancer patients still had higher risk of suicide death after cancer diagnosis. Future studies should address the racial differences of psychological stress after cancer diagnosis. [Table: see text]
