Comparative Analysis of Bone Marrow Smears and Biopsies Synchronous Check for Myeloma Patients / 现代检验医学杂志

ABSTRACT

Objective The purpose of this paper is to understand the advantages and disadvantages of the bone marrow smears and bone marrow biopsy in multiple myeloma diagnosis and efficacy judgment,explicit the value of bone marrow smears and bone marrow biopsy synchronous check in the diagnosis and treatment observation of multiple myeloma.Methods With two step-suction two biopsy specimens assay,obtained specimens of bone marrow smears and bone marrow biopsy,retrospective-ly analysed results of 283 multiple myeloma patients bone marrow smear and biopsy,and made a comparative study on the degree of bone marrow hyperplasia,myeloma cell morphology,the degree of tumor cell infiltration,proliferation pattern,bone marrow stromal pathological changes,and fibrosis cases.Results The degree of proliferation of bone marrow biopsy sections and infiltration of plasma cells was significantly higher than that of bone marrow smears,statistically there was a significant difference (P <0.01).Multiple myeloma diagnostic sensitivity by bone marrow biopsy sections was significantly higher than by the bone marrow smears,the difference was statistically significant (P < 0.05).Plasma cells in bone marrow biopsy tumor proliferation modesclusterpiece nodular type 33 cases (11.66%),interstitial-type 86 cases (30.39%),among nodular interstitial type 112 cases (39.58%),diffuse cypriot real 52 cases (18.37%).Plasma cells in bone marrow smears tumor morphologysmall mature plasma cell type 77 cases (27.21%),immature plasma cell type 148 cases (52.30%),protoplas-mic cell type 36 cases (12.72%),reticular plasma cell type 22 cases (7.77%).Conclusion Marrow biopsy can accurately reflect the degree of bone marrow hyperplasia,plasma cell tumor proliferation mode and infiltration degree,myelofibrosis sit-uation;bone marrow smears Wright-Giemsa staining,plasma cell tumor morphology was clear,typicalfeatured,and easily i-dentifiable.Bone marrow smear and biopsy synchronous check can improve the sensitivity and accuracy for multiple myeloma diagnosis,which has very important significance for multiple myeloma diagnosis and treatment observation.
