Abstract:
Objective To investigate the value of bone marrow imprints in the cytomorphology diagnosis.Methods A total of 354 cases of bone marrow smears,imprints,and sections were analyzed from January 2011 to December 2013 to detect morphological diagnosis difference.Results Bone marrow imprints in groups of extremely reduced,significantly reduced,normal,slightly increased,increased significantly,and extreme increase were better than that of smear which nucleated cells quantity assessment(P ＜ 0.01).Smears and imprints were similar (P ＞0.05).Imprints nucleated cell number decreased mostly were the same as smear,but smear reduced imprints mostly normal or increased.The bone marrow sections nucleated cells quantity as the standard,smears and imprints had high coincidence rate in the group of nucleated cells reduced (87.5％ and 96.9％),and imprints were higher than smear in the group of nucleated cells quantity in normal and increased(87.8％ and 95.7％ vs 68.3％ and 55.8％),and the difference was statistically significant.Imprints were better than smear in specificity,Youden index,and sensitivity.Patients with plasma cell myeloma (PCM) imprint plasma cell volume and immature plasma cells were higher than that of smear (42.73 ± 10.47 and 13.60 ± 4.83 vs 24.67 ± 11.18 and 11.07 ± 5.82) with a statistically significant difference (P ＜ 0.05).Conclusions Imprints have characteristics both smear and sections,and imprints are superior to smears in assessment of nucleated cells and tumor cell invasion degree.Smear combined with imprints can improve the diagnosis level of bone marrow cell cytomorphology.
