Greiber IK, Mikkelsen AP, Karlsen MA, et al. - Via performing a historical prospective cohort study using data from nationwide registries, researchers here examined the risk of venous thromboembolism (VTE) during pregnancy and postpartum in patients with cancer in pregnancy vs those without cancer. Patients with cancer in pregnancy have a markedly higher risk of pregnancy associated VTE compared to patients without cancer. In pregnancy related VTE risk assessment, the presence of cancer alone may be sufficient to indicate thromboprophylaxis. Among 3,581,214 pregnancies included in the study, they identified 1,330 women with cancer in pregnancy. Findings revealed a markedly higher risk of pregnancy associated VTE among patients with cancer in pregnancy vs those without cancer. The presence of cancer alone seems to be sufficient to indicate thromboprophylaxis in pregnancy related VTE risk assessment.
