Women with ovarian cancer had a higher risk of suicide and accidental death than the cancer-free group (SMR=1.86; 95% CI [1.54-2.25] and SMR=1.54; 95% CI [1.39-1.71]). Subgroup analysis indicated that only patients with type II epithelial ovarian cancer (SMR=2.31; 95% CI [1.83-2.91]) had an increased risk of suicide, and those with type I and type II epithelial ovarian cancer (SMR=1.65; 95% CI [1.39-1.97] and SMR=1.49; 95% CI [1.30-1.70]) were at a higher risk of accidental death. Patients with ovarian cancer who were younger, white, diagnosed with high-grade, non-metastatic cancer and pelvic exenteration were at a higher risk of suicide. Additionally, pelvic exenteration increased the risk of suicide but not the risk of accidental death among these women.
