Although management of CAT in this population follows standard guidelines, less is known about the appropriateness of thromboprophylaxis in patients with different types of cancer. Patients with cancer undergoing radiotherapy may also be at increased risk of bleeding, which may be further worsened by anticoagulation.

Based on its onset, preclampsia can be categorized into early-onset (E-PE) or late-onset (L-PE) preeclampsia.
