Pilot Study of Post-thrombotic Syndrome & Predictors of Recurrence in Cancer Patients With Catheter-related Thrombosis

The goal of the pilot study is to determine if a multicenter prospective cohort study of cancer patients with blood clots associated with catheters is feasible. Cancer patients with catheter-related thrombosis treated with one month of anticoagulation will be evaluated for for post-thrombotic syndrome. Laboratory biomarkers will be evaluated as predictors of recurrent thrombosis.

NCT01999179 Venous Thrombosis Neoplasms
MeSH: Thrombosis Venous Thrombosis Postthrombotic Syndrome Postphlebitic Syndrome Recurrence
HPO: Deep venous thrombosis Venous thrombosis

1 Interventions

Name: Heparin, Low-Molecular-Weight, or direct oral anticoagulants

Description: Cancer patients will be treated with enoxaparin 1 mg/kg subcutaneously every 12 hours for one month following catheter removal or alternate enoxaparin dose or interval based on anti-factor Xa testing obtained by the clinical team or either apixaban, rivaroxaban, dabigatran, edoxaban following a catheter related blood clot

Type: Drug

low-molecular-weight heparin or direct oral anticoagulant


Primary Outcomes

Description: Recruitment of 56 patients in 1 year and 80% completion of post-thrombotic syndrome assessments by enrolled patients

Measure: Number of cancer patients enrolled with catheter-related thrombosis treated with 1 month of anticoagulation

Time: 1 year

Secondary Outcomes

Description: Obtaining 80% of samples from enrolled patients

Measure: Number of plasma samples obtained for biomarker analysis to predict recurrent venous thrombosis

Time: 1 year

Other Outcomes

Description: <20% will have incidence of post-thrombotic syndrome 6 months after catheter removal

Measure: Incidence of post-thrombotic syndrome in cancer patients with catheter-related thrombosis treated with 1 month of anticoagulation

Time: 6 months after catheter removal

Description: <20% will have incidence of post-thrombotic syndrome 6 months after catheter removal

Measure: Incidence of recurrent thrombosis in cancer patients with catheter-related thrombosis treated with 1 month of anticoagulation

Time: 6 months after catheter removal

Description: <20% will have incidence of post-thrombotic syndrome 6 months after catheter removal

Measure: Incidence of major and clinically relevant non-major bleeding in cancer patients with catheter-related thrombosis treated with 1 month of anticoagulation

Time: 6 months after catheter removal
