The role of thromboelastography in predicting hemorrhage risk in patients with leukemia

This study aimed to compare the efficacy of thromboelastography (TEG) and conventional coagulation methods in predicting hemorrhage risk in patients with leukemia.A total of 226 patients diagnosed with leukemia were included and divided into bleeding and nonbleeding groups. All patients had their blood samples taken for TEG test to measure the reaction time (R time), alpha ( angle), and maximum amplitude (MA) as well as measure platelet count (PLT), prothrombin time, and activated partial thromboplastin time. Patients were followed up for bleeding episodes.The multivariate analysis showed that PLT [odds ratio (OR)=0.993] and MA (OR=0.921) have better association with bleeding risk. Receiver operating characteristic (ROC) analysis showed that the combination of PLT and MA (AUC=0.824) was better for hemorrhage risk prediction than PLT [area under the curve (AUC)=0.730] and MA (AUC=0.819) alone.The combination of TEG and conventional coagulation methods could help in assessing the risk of hemorrhage in patients with leukemia.
