Venous thromboembolism and effect of comorbidity in bladder cancer: A danish nationwide cohort study of 13,809 patients diagnosed between 1995 and 2011

BC is associated with increased risk of VTE, compared with the general Danish population. Risks are particularly high for VTE after cystectomy. Risk did not increase with higher comorbidity burden, as the relative risk of VTE was greatest among patients without comorbidity. Clinical attention to VTE risk, particularly cystectomy-related VTE, in patients with BC is appropriate irrespective of comorbidities.
