Cancer Associated Thrombosis : What is the Proportion of Patients Ineligible to a Study as CARAVAGGIO

Cancer Associated Thrombosis: What is the Proportion of Patients Ineligible to a Study as CARAVAGGIO (a Retrospective Multicenter Study)

Venous thromboembolism is a common and fatal disease closely related to cancer. The therapeutic challenge is major due to the high risk of recurrent thromboembolism and bleeding in patients with cancer.

Guidelines recommend the use of low molecular-weight heparin for the treatment of Cancer-Associated venous Thromboembolism (CAT) at least for 3 to 6 months of treatment.

However, recent advances through the results of several therapeutic trials such as CARAVAGGIO (NCT03045406) open the door to the use of Direct Oral AntiCoagulants (DOACs) as first-line therapy.

Nevertheless, extrapolation of its results may be limited owing to a large number of inclusion and exclusion criteria, which may have selected a reduced population.

The proportion of patients admitted with acute CAT who may not eligible to a trial as CARAVAGGIO is unknown.
