[Significance of Simultaneous Analysis of Bone Marrow Smear and Bone Marrow Biopsy in the Diagnosis of Multiple Myloma].

OBJECTIVE

To explore the value of bone marrow smear and biopsy simultaneously applied to diagnosis of multiple myloma (MM).

METHODS

Clinical data of 30 cases of multiple myloma were collected from our hospital in the year 2014 and analyzed retrospectively, and the results of the bone marrow smear and the simultaneous bone marrow biopsy were compared.

RESULTS

Hyperplasia levels in bone marrow biopsy was significantly higher than that in bone marrow smears, and the active and highly active hyperplasia of nucleated cells were observed in all the bone marrow biopsies; the myeloma cells showed a focal or diffuse distribution, the binuclear or polynuclear myeloma cells were observed in 22 patients (73%), but the detection rate of abnormal myeloma cells was 40% in bone marrow smear (P < 0.05). There was mild to moderate hyperplasia of fibrous tissue in bone marrow biopsy, and the hyperplasia degeree of fibrous tissue strongly positively correlated with the myeloma cell ratio (r = 0.412).

CONCLUSION

The bone marrow smear and aspiration biopsy can complement each other so as to reduce the misdiagnosis rate, therefore contributes to the early diaglosis and treatment.
