- Abstract
Summary: Venous thromboembolism (VTE) is a well‐known complication in adults receiving asparaginase (ASNase)‐based intensification chemotherapy for acute lymphoblastic leukaemia (ALL). The optimal preventative strategy is unclear. Our objective is to determine the effects of low‐molecular‐weight heparin (LMWH) as primary VTE prophylaxis. A single‐centred retrospective cohort study of adult patients with Philadelphia chromosome negative (Ph−) ALL who received ASNase‐based intensification from 2001 to 2017, with prophylaxis given from 2011 to 2017. In all, 214 patients were included in this study with 99 in the historical control group and 125 in the prophylaxis group. The mean (range) enoxaparin dose was 0·79 (0·39–1·2) mg/kg. Of the 125 patients in the prophylaxis group 17 (13·6%) developed VTE during the intensification phase, while 27/99 patients (27·3%) in the control cohort experienced at least one thrombotic event (odds ratio [OR] 0·42, 95% confidence interval [CI] 0·21–0·83). Overall, the main sites of VTE incidences included deep vein thrombosis in the lower extremity (54·6%), pulmonary embolism (13·6%) and catheter‐related thrombosis (22·7%). In addition, we found that after adjusting for age, T‐phenotype ALL was associated with VTE development (OR 3·07, 95% CI 1·04–9·08). There was no documented major bleeding in the prophylaxis group. LMWH prophylaxis reduced the incidence of symptomatic VTE in adult patients with ALL receiving intensification chemotherapy with ASNase.
