OBJECTIVE: To analyze the time trend of the standardized suicide rate among cancer patients in the United States from 1975 to 2016, and to provide reference for preventing or intervening the suicidal tendency of cancer patients.
METHODS: Based on the SEER database established by the National Cancer Institute of the United States, the relevant data of cancer patients from 1975 to 2016 were collected, and the standardized suicide rate, annual percentage change rate (APC) and annual average percentage change rate (AAPC) were calculated by JoinPoint software to analyze the temporal trend of cancer patients' suicide.
RESULTS: The standardized suicide rate of cancer patients showed a decreasing trend from 1975 to 2016 (AAPC=-4.6%, P< 0.001). By gender, there was a significant difference in the time trend of standardized suicide rate between male and female cancer patients(χ2=52.78, P< 0.001), the standardized suicide rate of male cancer patients decreased more than that of females (male: AAPC=-4.7%, P< 0.001; female: AAPC=-4.4%, P< 0.001), but the standardized suicide rate of male cancer patients was always higher than that of females; By age, there were significant differences in the time trend of standardized suicide rate among cancer patients in different age groups(χ2=459.68, P< 0.001), the standardized suicide rate of cancer patients aged 75 and above was higher than that of other age groups, and the standardized suicide rate of cancer patients in this group had the smallest decrease trend (AAPC=-1.3%, P< 0.001).
CONCLUSION: From 1975 to 2016, although the standardized suicide rate of cancer patients decreased year by year, cancer patients are still the key population for suicide intervention, especially for male and elderly cancer patients; therefore, prevention and intervention should be strengthened. © 2022, Editorial Board of Chinese Journal of Cancer Prevention and Treatment.
