多发性骨髓瘤骨髓活检切片与涂片的比较

本研究探讨骨髓活检在多发性骨髓瘤诊断中的意义。观察279例多发性骨髓瘤患者的骨髓涂片及骨髓活检切片，就骨髓增生程度，骨髓中浆细胞浸润度及增殖模式，骨髓间质病理变化及骨髓纤维化程度进行比较。结果表明：骨髓活检切片显示的增生程度明显高于骨髓涂片；骨髓切片的浆细胞增殖模式与骨髓涂片的浆细胞比例不完全一致；骨髓纤维化程度对骨髓涂片和活检的细胞增生度一致性有影响。结论：骨髓活检切片比骨髓涂片能更准确地反映骨髓增生程度、浆细胞浸润情况及增殖模式，对多发性骨髓瘤的诊断具有重要价值。

Comparison of Bone Marrow Biopsy and Smear Efficacy in Patients with Multiple Myeloma

This study was aimed to explore the significance of the bone marrow biopsy for the diagnosis of multiple myeloma. Bone marrow smears and bone marrow biopsy originated from 279 cases of multiple myeloma were detected and compared in term of bone marrow hyperplasia, bone marrow plasma cell infiltration, proliferation mode, pathological changes in the bone marrow stroma and myelofibrosis. The results indicated that the levels of proliferation in bone marrow biopsy was significantly higher than that in bone marrow smears. Plasma cell proliferation mode in bone marrow biopsy was not completely consistent with the proportion of plasma cells in bone marrow smears. The myelofibrosis level displayed influence on the consistency of the proliferation between bone marrow smears and biopsies. It is concluded that as compared with bone marrow smears the bone marrow biopsy can more accurately reflect the levels of bone marrow hyperplasia and bone marrow plasma cell infiltration, proliferation mode and so on. Bone marrow biopsy is valuable for multiple myeloma diagnosis.
