Tumour-related Characteristics Associated with Higher Risk of Suicide and Accidental Death
Patients with high-grade ovarian cancer had a higher risk of suicide than those with low-grade ovarian cancer (17.88 /100,000 person-years; SMR=2.37; 95% CI [1.77-3.17] vs 7.23/100,000 person-years; SMR=0.94; 95% CI [0.59-1.49]), while there was no difference in the risk of accidental death among the two groups (44.10 /100,000 person-years; SMR=1.32; 95% CI [1.10-1.59] and 41.78 /100,000 person-years; SMR=1.48; 95% CI [1.22-1.80]). Patients with regional cancer and those with distant cancer were more likely to die from suicide (15.19 /100,000 person-years; SMR=2.02; 95% CI [1.24-3.30] and 16.02 /100,000 person-years; SMR=2.15; 95% CI [1.63-2.85]), while patients with localized ovarian cancer (9.82 /100,000 person-years; SMR=1.31; 95% CI [0.92-1.85]) had the same risk of suicide as their matched general population. Moreover, patients with distant ovarian cancer had the highest risk of accidental death (54.91 /100,000 person-years; SMR=1.59; 95% CI [1.37-1.85]), and patients with localized ovarian cancer and those with regional ovarian cancer had the same risk of accidental death (41.11 /100,000 person-years; SMR=1.50; 95% CI [1.27-1.78]; 44.61 /100,000 person-years; 95% CI [1.05-1.86]).
