Brief Summary

To evaluate the efficacy and safety of edoxaban in the prevention of tumor catheter-related thrombosis (CVC/PICC) in high-risk patients

Detailed Description

This study was a prospective, interventional, open, randomized controlled clinical study. A total of 366 patients with cancers who will be assessed as high risk by the thrombosis risk prediction model (refer to Appendix 1) are planned to be enrolled. All patients are planned to undergo anti-tumor chemotherapy and receive CVC or PICC catheterization on the first day of chemotherapy. The patients are randomly divided into the experimental group and the control group at a ratio of 1:1. The experimental group is treated with edoxaban to prevent catheter-related thrombosis, and the control group won't be treated with edoxaban. Venous vascular ultrasound will be conducted before the start of each cycle of chemotherapy or whenever patients have any thrombosis-related symptoms to assess whether they have catheter-related thrombosis. The incidence of catheter-related thrombosis during catheter. 1. The safety of edoxaban.2. The death caused by catheter-related thrombosis.3. The time of non thrombotic events.4. The incidence of venous thrombosis.

2. Allergy to the active ingredient of edoxaban tablets or other excipients.

3. There is clinically significant active bleeding.

4. Platelet <50×109/L.

5. Liver disease with coagulopathy or clinically relevant bleeding risk.

6. A lesion or condition with a significant risk of major bleeding, such as current or recent gastrointestinal ulcer, recent brain or spinal injury, recent brain, spinal, or ophthalmic surgery, recent intracranial hemorrhage, esophageal varices, arteriovenous malformations, vascular aneurysms, or major intravertebral or intracerebral vascular malformations.
