Real-world analysis of strategies to prevent thrombosis and bleeding in adults with ALL treated with asparaginase.

ABSTRACT: The prognosis of adult patients with acute lymphoblastic leukemia (ALL) has improved with the incorporation of pediatric-inspired regimens that contain PEGylated asparaginase (PEG-Asp). However, PEG-Asp administration is associated with an increased rate of thrombosis. Data regarding the benefits of antithrombin (AT) repletion and prophylactic anticoagulation in adults receiving PEG-Asp-based regimens are limited. We performed a retrospective study to evaluate the rates of induction thrombosis and bleeding among adults receiving ALL therapy containing Asp at 6 academic centers in the United States. Of 233 patients who met the inclusion criteria, 98.3% received PEG-Asp. Ninety-six patients (41.2%) had their AT levels monitored, 58 patients (24.9%) received AT repletion, and 41 patients (17.
