Incidence of Suicide and Accidental Death Among Patients with Ovarian Cancer
A total of 107 suicidal and 373 accidental deaths occurred among 149,204 patients with ovarian cancer, followed by 768,840.17 person-years (Table.1 ). The suicide rate was 13.92/100,000 person-years and the accidental death rate was 48.51/100,000 person-years among ovarian cancer patients. Women with ovarian cancer had an 86% higher risk of suicidal death (SMR=1.86; 95% CI [1.54-2.25]) and 54% higher risk of accidental death (SMR=1.54; 95% CI [1.39-1.71]) than the general US population with the same distribution of age, sex, and race. The number of suicide and accidental deaths among patients with ovarian cancer ranks second in patients with gynaecologic cancers, between uterine cancer and cervical cancer. From 1973 to 2017, the relative number of suicide and accidental deaths decreased gradually in patients with uterine cancer and unchanged among patients with cervical cancer, while the relative number of suicide and accidental deaths remained elevated among patients with ovarian cancer (Supplementary Figure.2 ).
