Abstract
We investigated the performance of research use only/cell population data (RUO/CPD) items obtained from the Beckman Coulter DxH800 automated hematologic analyzer in discriminating MDS patients from cytopenic patients without MDS.Total of 14 routine CBC, 18 research use only (RUO) items, and 70 CPD items were obtained retrospectively at diagnosis. The results were then compared between 94 MDS patients and 100 cytopenic patients without MDS. In items with statistically significant differences, receiver operating characteristic (ROC) analysis was performed and the results were compared.Four CBC/RUO items [red cell distribution width-standard deviation (RDW-SD), immature reticulocyte fraction (IRF), mean sphered cell volume (MSCV), high light scatter reticulocytes (HLR)], and two CPD items [mean volume of neutrophils (NE-V-Mean) and mean volume of early granulated cells (EGC-V-Mean)] showed area-under the curve (AUC) scores > 0.750. Notably, four RUO/CPD items (MSCV > 81.4/HLR > 0.15%/NE-V-Mean > 145/EGC-V-Mean > 156) showed high sensitivity (91.9%/93.6%/88.1%/90.2%, respectively) in discriminating MDS patients from cytopenic patients without MDS. With these six items, scores ≥ 4 (defined as ≥ 4 items exceeding cutoff values out of six items) showed AUC scores/sensitivity/specificity/accuracy (0.891/87.3%/79.0%/83.0%, respectively).Six CBC/RUO/CPD items showed satisfactory AUC scores of > 0.750, and four RUO/CPD items showed high sensitivity in discriminating MDS patients from cytopenic patients without MDS. Scoring system with six items showed high sensitivity, specificity, and accuracy with decision criteria of ≥ 4 scores. Therefore, DxH800 RUO/CPD items would be useful in discriminating MDS patients from cytopenic patients without MDS.
期刊介绍:
The Journal of Hematopathology aims at providing pathologists with a special interest in hematopathology with all the information needed to perform modern pathology in evaluating lymphoid tissues and bone marrow. To this end the journal publishes reviews, editorials, comments, original papers, guidelines and protocols, papers on ancillary techniques, and occasional case reports in the fields of the pathology, molecular biology, and clinical features of diseases of the hematopoietic system.
The journal is the unique reference point for all pathologists with an interest in hematopathology. Molecular biologists involved in the expanding field of molecular diagnostics and research on lymphomas and leukemia benefit from the journal, too. Furthermore, the journal is of major interest for hematologists dealing with patients suffering from lymphomas, leukemias, and other diseases.
The journal is unique in its true international character. Especially in the field of hematopathology it is clear that there are huge geographical variations in incidence of diseases. This is not only locally relevant, but due to globalization, relevant for all those involved in the management of patients.
