RESUMO
Purpose:To analyze the immunophenotype character of malignant lymphoma with bone marrow involvement by means of Flow Cytometry (CD45/SSC gate).Methods:Bone marrow of malignant lymphoma patients was detected by Flow Cytometer(CD45/SSC gate),bone marrow smear was simultaneously performed as control.Results:(1) Bone marrow of 34 malignant lymphoma patients was examined by Flow Cytometry.23 cases were detected to have bone marrow involvement.(2) Among these 23 cases,19 cases were non-Hodgkin's lymphoma(NHL),4 cases were Hodgkin's lymphoma(HL).The highest frequency antigen marker of B cell NHL was CD19 and CD20,T cell NHL was CD7,and HL was CD9.Conclusions:(1)Flow Cytometry(CD45/SSC gate) is a feasible and effective method to detect patients with bone marrow involvement.(2) The antigen marker of B cell NHL is CD19 and CD20,T cell NHL is CD7 and HL is CD9.
