[Application Value of Immunohistochemistry and Bone Marrow Morphology Detection in the Diagnosis and Clinical Staging of Non-Hodgkin's Lymphoma].

OBJECTIVE: To investigate the application value of immunohistochemistry detection and bone marrow morphology analysis in the diagnosis and clinical staging of non-Hodgkin's lymphoma. METHODS: Sixty-four cases of non-Hodgkin's lymphoma were selected in our hospital and the immunohistochemistry detection of pathologic specimens was perforemed by related monoclonal antibody and the bone marrow morphology was also examined. RESULTS: The positive rate of antibody CD79a on B cell lymphoma was 84.62%, and CD20 was 91.43%; the positive rate of antibody CD45RO on T cell lymphoma was 87.50%, and 88.89% of CD3. The bone marrow involvement was found in 10 cases (15.63%), 8 cases(12.50%) progressed to lymphoma - leukemia period; lymphoma cells were lower than 5% in 20 cases (31.25%). CONCLUSION: Immunohistochemistry detection can help to define the type of T or B cell lymphoma in patients with non-Hodgkin's lymphoma, the bone marrow morphology analysis can clear whether the patients with non-Hodgkin's lymphoma suffered from bone marrow involvement and whether developed to lymphoma- leukemia period. These methods possess more high value in clinical application.
