We investigated the safety and effectiveness of DOACs in patients with active cancer. Patients and Methods: To investigate the safety and efficacy of DOACs, we retrospectively extracted 312 consecutive patients with active cancer who were prescribed edoxaban, rivaroxaban or apixaban for VTE. Results: The most common primary cancer sites were the lung, stomach, colon/rectum, hematology, ovary, and pancreas. Fifty patients (16\%) discontinued DOACs due to clinically relevant bleeding; major bleeding events occurred in 18 patients (5.4\%). Thrombosis reduced or resolved in 144 of 167 evaluable patients (86\%). In particular, pulmonary embolism was reduced or resolved in 46 of 50 patients (92\%). Conclusion: Our findings revealed that DOACs for cancer-associated VTE are as safe and effective as conventional anticoagulation therapy.}, issn = {0258-851X}, URL = {https://iv.iiarjournals.org/content/35/5/2747}, eprint = {https://iv.iiarjournals.org/content/35/5/2747.full.pdf}, journal = {In Vivo} }
