ABSTRACT
OBJECTIVE@#To explore the role of neutrophil-to-lymphocyte ratio(NLR) in patients with newly diagnosed essential thrombocythemia(ET) and its relationship with thrombotic events.@*METHODS@#The clinical and follow-up data of 150 ET patients were retrospectively analyzed. The risk factors of thrombotic events and role of NLR by statistical methods.@*RESULTS@#Age (P<0.01) and JAK2V617F mutation (P<0.01) were the independent risk factors for thrombotic events at diagnosis; WBC count (P<0.05), NLR (P<0.01), age (P<0.05) and thrombosis history at diagnosis (P<0.05) were independent risk factors for future thrombotic events. The ROC curve showed that NLR for prediction of future thrombotic events was suprior to other risk factors. The Kaplan-Meier analysis showed that the progress-free survival time in thrombotic events patients with higher NLR (median survival 22.3 months, 95% CI17.8-26.8) was significantly shorter than that of patients with lower NLR (median survival 55.5 months, 95% CI53.4-57.5) . After follow-up 60 months, the thrombosis progress-free survival in lower NLR patients reached 97.4%, while that in the patients with higher NLR was rate 46.7%.@*CONCLUSION@#NLR at diagnosis is a better predictive parameter for future thrombotic events than other clinical parameters in ET patients, but without corralations with thrombosis at diagnosis.
