Clinical Features and Prognostic Analysis of Newly Diagnosed Diffuse Large B-cell Lymphoma Combined with Hemophagocytic Syndrome
Objective:To compare the clinical features and prognosis between newly diagnosed diffuse large B-cell lymphoma(DLBCL)patients with and without hemophagocytic syndrome(HPS).Methods:The clinical data of 45 DLBCL patients in Gansu Provincial Hospital from January 2012 to December 2021 were retrospectively analyzed.The patients were divided into HPS group(15 cases)and non-HPS group(30 cases).The clinical features and prognosis of the two groups were compared,and survival analysis was performed using Kaplan-Meier method.Results:Patients with HSP were mostly characterized by fever,cytopenia and splenomegaly.The levels of ferritin and soluble CD25 increased in all patients.The level of fibrinogen decreased in 66.67%patients,while triglyceride increased in 53.33%patients,and bone marrow hemophagocytosis occurred in 80.00%patients.Compared with non-HSP group,the proportions of patients with advanced stage(Ann Arbor stage Ⅲ/Ⅳ)and lactate dehydrogenase(LDH)≥ 240 U/L were higher in HSP group(both P<0.05).The median survival time of HSP group was 8.0 months,which was significantly shorter than 45.5 months of non-HSP group(P<0.001).Conclusion:The DLBCL patients with HPS have later Ann Arbor stage,higher LDH and shorter overall survival time compared with patients without HPS.
