Abstract:
Background and purpose:Bone marrow cytomorphology is the main approach for determination of bone marrow involvement in patients with malignant lymphomas. In recent years, with the development of detection of cellular surface markers and molecular biology, flow cytometry (FCM) and polymerase chain reaction (PCR) were gradually applied in the detection of bone marrow in malignant lymphomas. Because such systematic research has not been done domestically , we performed a study to compare diagnostic value and clinipathological signifi cance of cytomorphology of bone marrow aspirates, immunophenotype detected by flow cytometry and immunoglobulin heavy chain gene rearrangement detected by polymerase chain reaction in bone marrow of B cell lymphomas. Methods: Bone marrow cytomorphology, FCM and PCR were simultaneously carried out in 75 bone marrows of B cell lymphoma and compared with each other. Results:(1)16 were demonstrated by cytomorphology, 36 by FCM, 33 by PCR. The positive rates were 21.3%, 48% and 44% respectively. The differences among these three methods have statistical signifi cance (P
