Tumour Treatment Associated with Higher Suicidal and Accidental Death Risk
The suicide rate of patients who did not undergo surgery for ovarian cancer (SMR=6.75; 95% CI [4.07-11.20]) was much greater than that among those who underwent surgery (SMR=1.57; 95% CI [1.27-1.94]). Among women who received surgical treatment, those who underwent pelvic exenteration had the least number of cases but the highest risk of suicide (29.67 /100,000 person-years; SMR=3.88; 95% CI [1.25-12.03]). Patients who underwent oophorectomy with hysterectomy had a higher risk of suicide as compared to those who underwent oophorectomy without hysterectomy (11.24 /100,000 person-years; SMR=1.42; 95% CI [1.01-2.00] vs 6.82 /100,000 person-years; SMR=1.09; 95% CI [0.52-2.28]). In addition, patients who did not undergo surgery for ovarian cancer and those who underwent oophorectomy with hysterectomy had a higher risk of accidental death compared with their matched general population (149.88 /100,000 person-years; SMR=2.32; 95% CI [1.77-3.04] and 40.20 /100,000 person-years; SMR=1.37; 95% CI [1.14-1.64]).
