Changes of Neutrophil Morphological Parameters in Peripheral Blood of Patients with Solid Tumor Treated with Granulocyte Colony Stimulating Factor / 现代检验医学杂志

ABSTRACT

Objective To study neutral particle particle(NEUT-X)change in the solid tumor patients with chemotherapy by granulocyte colony-stimulating factor(G-CSF).Methods Chose that 52 cases of cancer chemotherapy with G-CSF(study group),32 cases of cancer chemotherapy patients without G-CSF(study control group)and 50 cases of healthy(healthy control group).The automatic hematology analyzer Sysmex XE-2100 were been examined the peripheral blood routine and collected the data which wes the morphological parameters of peripheral white blood cell.The changes of neutrophil N-X pa-rameters during chemotherapy were analyzed,and the clinical infection fever rates of three groups were collected to reveal the relationship between leukocyte morphological parameters and body resistance.Results In the study group,study control group and healthy control group,the NEUT-X was 1 324(890.2,1 358.0),1 440(1 397.3,1 466.3)and 1 329(1 295.1, 1 359.4),and the difference was statistically significant between the three groups(F=10.778,P=0.002).In study group, the count of WBC before and after G-CSF was 0.99(0.22,1.75)×109/L and 7.53(1.00,14.05)×109/L respitively and there was the significant difference(Z=-2.395,P=0.005).In study group patients the NEUT-X was 1 382(1 323.6,1 440.4)and 1 324(890.2,1 358.0)respectively and there was a significant difference(Z=-2.832,P=0.004).Between the study group and the study control group,there were 23/52 cases and 4/32 cases infection in patients with fever case(Z=9.14,P=0.002).Conclusion By G-CSF the leukocyte counts increased in patients with chemotherapy,and reduced neu-trophil NEUT-X parameters,and the infection rate was higher than the non G-CSF patients.The neutrophil granularity will be useful for evaluating of patients with chemotherapy for solid tumor immunity.
