By stratified analysis, patients that knew their cancer diagnosis had longer survival time in each subgroup (P  less then  .001, all subgroups). Cox regression analysis showed that knowing their cancer diagnosis was an independent influencing factor for survival in patients with LC (hazard ratio, 0.826; 95% CI, 0.802-0.851; P  less then  .001). CONCLUSIONS Knowing their cancer diagnosis contributed to longer survival time in patients with LC, providing clear evidence that medical staff and patients' families should fully disclose cancer diagnoses to patients. © 2020 John Wiley & Sons, Ltd.BACKGROUND Data relating to the association between inflammatory bowel disease (IBD) and pregnancy outcomes are lacking in Korea. AIMS To determine the incidence rates of pregnancy outcomes in women with IBD. METHODS A nationwide population study was performed using the Korean National Health Insurance claims database. A total of 2058 women with IBD consisting of ulcerative colitis (UC, n = 1469) and Crohn's disease (CD, n = 589) were pregnant between 2007 and 2016. We compared their incidence of pregnancy outcomes with 20 580 age-matched controls without IBD. We also stratified the patients into those with quiescent to mild and moderate to severe IBD and compared the outcomes between them. RESULTS The pregnancy rate of women with IBD was lower than that of women without (25.7% vs 32.3%, P less then 0.001). Caesarean section (46.5% vs 38.8%, odds ratio [OR] 1.43, 95% confidence interval [CI] 1.17-1.75), and intrauterine growth retardation (IUGR) (3.0% vs 1.0%, OR 2.89, 95% CI 1.59-5.26) were increased in CD patients than the controls. In regards to disease severity, there were no significant differences in pregnancy outcomes between patients with quiescent to mild IBD and the controls. However, the live birth rate of patients with moderate to severe IBD was lower than that of the contro
