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

OBJECTIVE: To explore the value of bone marrow smear combined with biopsy in the diagnosis of lymphoma.

METHODS: Clinical data of 50 cases of lymphoma from our hospital were analyzed retrospectively, and the results of the bone marrow smear and the bone marrow biopsy were compared simultaneously.

RESULTS: The decision for the degree of bone marrow hyperplasia in bone marrow biopsy slice was superior to that in smear, and the active or highly active hyperplasia of nucleated cells were observed in all the bone marrow biopsies; the lymphomatic cells were observed in bone marrow smear of the 12 patients(24%), but the bone marrow biopsies showed a higher detection rate of lymphomatic cells 44% in 22 patients(P<0.05); The hyperplasia of bone marrow fibrous tissue, mainly mild to moderate, were the common in cases with bone marrow involvement and the severity of bone marrow fibrosis positively correlated with the number of lymphomatic cells.

CONCLUSION: Biopsy combined with aspiration can improve the accuracy of diagnosis in lymphoma with bone marrow involvement.
