Abstract
To observe the evaluation value of characteristics of bone marrow cell morphology and immunophenotype in patients with non-Hodgkin lymphoma (NHL) leukemia on the bone marrow invasion of NHL. The clinical data of 104 patients with NHL treated in the hospital from March 2016 to March 2021 were retrospectively analyzed, the characteristics of bone marrow smear morphology were recorded, and the analysis of bone marrow immunophenotype was performed, the evaluation value of bone marrow cell morphology and immunophenotype on NHL bone marrow invasion was analyzed. One hundred and four patients with NHL leukemia were found to have increased lymphoma cells by examination of bone marrow cell morphology, including 57 cases of B-cell type, 39 cases of T-cell type and 8 cases of NK/T cell type. The characteristics of bone marrow cell morphology were as follows: the cell body was large, irregular or round like in shape, the cytoplasm was much and mostly stained blue, a few cells could see a few granules, the nucleus was round or round like, some were twisted, the chromatin was thick and nucleolus was different, of which the T-cell type lymphoma cells had strong heteromorphism and more obvious nucleolus. B-cell type mainly expressed CD19, HLA-DR and CD20, and the positive rate was ≥70%. T-cell type mainly expressed CD7, HLA-DR and CD38, and the positive rate was ≥40%. NK/T cell types mainly expressed CD56 and CD161, and the positive rates was ≥50%. Compared the proportion of lymphoma cells between bone marrow smear and immunophenotype examination, there was no statistical significant difference (P>0.05). The characteristics of bone marrow cell morphology and immunophenotype have certain application value in the evaluation of bone marrow invasion in patients with NHL leukemia, both can complement each other and provide a feasible mean for the effective evaluation of bone marrow invasion in patients with NHL leukemia.
