Secondary Prevention of VTE in Patients With Cancer and Catheter-Related Upper Extremity Deep Vein Thrombosis

Apixaban is Health Canada approved for routine treatment and secondary prevention of VTE. Upon enrollment and during follow-up, patients will be managed with a prophylactic dose of apixaban (2.5 mg orally twice daily) as long as either a CVC or active cancer is present. Apixaban will be stopped at the time of CVC removal and when cancer is in remission. Patients will be instructed to contact the study team when their CVC is removed (to determine if apixaban should be continued, based on cancer status at the time), or any thrombotic or bleeding concerns were to occur in between visits. The investigators will record loss to follow-up, drop out, or death during the study.
