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]).
