Abstract:
Objective To investigate the application of lymphocyte parameters in screening the lymphocyte proliferation and re-active hyperplasia disease.Methods 128 cases as the healthy control,100 cases of lymphoma,35 cases of multiple myeloma(MM), 34 cases of lymphocytes reactive hyperplasia(RL)and 5 cases of chronic lymphocytic leukemia(CLL)were selected and performed the peripheral blood cells analysis by the Sysmex XE-2100 hematology analyzer.The relevant lymphocyte parameter values were re-corded and the comparative analysis in the difference between the disease groups and the control group was performed.The role of each lymphocyte parameter in screening the lymphocyte proliferation and reactive hyperplasia diseases was evaluated by the receiver operating characteristic curve(ROC curve).Results The high fluorescence lymphocytes(HFL),in the control group was 0.008 ± 0.008,in the lymphoma group was 0.016±0.058,in the MM group was 0.019 ±0.063,in the RL group was 0.040 ±0.070,and CLL group was 0.388±0.158.Compared with control group,the difference of RL and CLL group was statistically significant(P <0.05).The percentage of lymphocytes(LY%,:the control group:34.4%±5.9%,the lymphoma group:26.6%±13.1%,the MM group:31.0%±13.1%,the RL group:29.2%±15.4% and the CLL group:44.5%±38.5%.The difference between the lympho-ma group and the control group was statistically significant(P <0.001).The lymphocytes structural parameters X(LY-X),the con-trol group:833.5 ± 22.7,the lymphoma group:867.9 ± 28.5,the MM group:867.9 ± 26.6,the RL group:859.2 ± 27.8 and the CLL group:894.0 ± 65.4.Except for the CLL group,the differences between other groups and control group were statistically significant(P <0.001).The lymphocytes structural parameters Y(LY-Y),the control group:659.6 ± 23.0,the lymphoma group:669.4 ± 43.5,the MM group:665.9 ± 37.1,the RL group:665.9 ± 40.0 and the CLL group:778.4 ± 152.1.Compared with the control group,the difference of the lymphoma group was statistically significant(P <0.05).AUC of the ROC curve in the pa-tients with lymphocyte proliferation and reactive hyperplasia disease by LY-X screening was 0.819,with the sensitivity of 80.5%and the specificity of 60.1% when cutoff value was 842.5.Conclusion The lymphocyte parameters,especially LY-X can reveal the
morphological changes of lymphocytes sensitively and contribute to screening the patients with lymphocyte proliferation and reactive hyperplasia disease.
