Thrombosis-Associated Risk Factors in Pediatrics and Adults Treated with Asparaginase-Containing Chemotherapy for ALL: A Systematic Review and Meta-Analysis
Abstract
Background
Thromboembolism is a serious complication in acute lymphoblastic leukemia (ALL). This systematic review and meta-analysis evaluated thrombosis incidence and risk factors across populations receiving asparaginase-based therapy.
Methods
From 214 studies (1994-2026), 58 met inclusion criteria, totaling 23,655 adult, pediatric, and mixed-population patients. Searches included Ovid MEDLINE, Embase, Cochrane CENTRAL, PubMed Central, and Google Scholar. Eligible studies were observational cohorts or clinical trials reporting thrombosis in ALL patients treated with asparaginase. Risk factors assessed included study design, asparaginase formulation, immunophenotype, gender, treatment phase, corticosteroid use, mediastinal mass, ABO blood group, body weight, and age. Random-effects models were used for meta-analysis, and risk of bias was assessed using ROBINS-I and RoB-2.
