To evaluate the utility of CD43 and CD200 in differentiating chronic lymphocytic leukemia (CLL) from other mature B-cell neoplasms. This was a cross-sectional study on patients diagnosed with B-cell neoplasms on flowcytometry. The median fluorescence intensity (MFI) of CD43, CD200 expressing neoplastic B-cells were compared between the CLL and non-CLL B-cell neoplasms followed by receiver operating characreristic curve (ROC) analysis. In addition, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of CD43 and CD200 in diagnosing CLL were analysed. A total of 137 patients were included. The CLL group consisted 87 patients and non-CLL group consisted 50 patients. The Mann–Whitney U test showed significant CD43 expression (U = 997.5, Z= − 5.265, p < 0.001) and CD200 expression (U = 932.0, Z = − 5.5, p < 0.01) in CLL patients compared to non-CLL patients. The area under the curve were 0.771 and 0.786 for MFI of CD43 and CD200 in differentiating CLL from non-CLL group respectively. The optimal cut-off of MFI for CD43 and CD200 were 1323 and 1775 respectively. The sensitivity, specificity, PPV and NPV of CD43 in diagnosing CLL cases were 97.7%, 66%, 83.3% and 94.2% respectively. The sensitivity, specificity, PPV and NPV of CD200 in diagnosing CLL cases were 100%, 32%, 71.9% and 100% respectively. CD43 and CD200 are useful markers in differentiating CLL from other mature B-cell neoplasms with higher MFI expression of both markers found in CLL. [ABSTRACT FROM AUTHOR] |
