Retrospective cohort study reveals high thrombosis and bleeding rates in patients with JAK2 clonal hematopoiesis, suggesting risk factor focus is essential.

Key Points

The study aims to evaluate clinical outcomes, particularly thrombosis and bleeding, in JAK2 V617F clonal hematopoiesis patients.
Conducted a retrospective cohort study of patients with JAK2 V617F mutations
Identified patients from the MGB Biobank and hematology clinic
Abstracted clinical records, labs, treatments, and outcomes including thrombosis and bleeding
Evaluated change in blood counts and calculated cumulative incidence rates
Used logistic regression models to determine risk factors for thrombosis.
Cumulative incidence of thrombosis was 46%, including 29% arterial and 17% venous
Major bleeding occurred in 24% of patients
Only prior history of arterial thrombosis was significantly associated with future arterial thrombosis
Five-year overall survival rate was 81%
No significant differences in outcomes between biobank and clinic patients.
