Long-term risks of coronary heart disease and cerebrovascular disease in ovarian, uterine and cervical cancer survivors: a nationwide study in Korea

Only few studies have evaluated the incidence of coronary heart disease (CHD) and cerebrovascular disease (CVD) among gynaecologic cancer survivors. We selected 26,880 gynaecologic cancer patients who underwent health check-ups within 2 years after diagnosis using the Korean National Health Insurance Service Database. They were compared with 79,830 non-cancer controls. Cox regression models were used to estimate hazard ratios (HRs). There was no significant relationship between gynaecologic cancer survivors and CHD or CVD events. However, 10 years after diagnosing cancers, the risk of angina increased in cancer survivors (adjusted HR = 1.193, 95% CI: 1.013-1.406). After 1 year of diagnosis, cancer patients with no initial comorbidities showed an increased risk of all CHD and CVD events (adjusted HR = 1.101, 95% CI: 1.020-1.189) and CHD alone (adjusted HR = 1.168, 95% CI: 1.055-1.293) compared with controls. CHD risk was also higher in the cancer group with no comorbidities after 10 years of diagnosis (adjusted HR = 1.284, 95% CI: 1.020-1.615). Overall, the risk of CHD or CVD did not increase in gynaecologic cancer survivors. However, cancer patients without any comorbidities showed a higher risk of CHD compared with control, the risk persisting until 10 years after cancer diagnosis.Impact Statement
