We performed a flow cytometric assay to identify CD26+ CML leukemic stem cells (LSCs) for its value as a standalone diagnostic investigation for CML and its utility for detection of residual disease in CML patients on therapy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients with clinical suspicion of CML\/CML on follow\u2010up were included, and peripheral (PB) and\/or bone marrow (BM) samples were utilized for flow cytometric analysis. PB and\/or BM of patients with diseases other than CML were used as controls. A pre\u2010titrated antibody cocktail containing CD45, CD34, CD38, and CD26\u00a0MoABs was used.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 104\u00a0samples (63\u00a0PB and 41 BM) from 64 patients [suspected CML (<jats:italic>n<\/jats:italic>\u00a0=\u00a030), CML on follow\u2010up (<jats:italic>n<\/jats:italic>\u00a0=\u00a015), and non\u2010CML (<jats:italic>n<\/jats:italic>\u00a0=\u00a019)] were tested. CD26+ LSCs were identified in all patients with a confirmed diagnosis of CML (median\u00a0=\u00a00.07 (range 0.002%\u201326.79%)). None of the patients in the control group (non\u2010CML) and follow\u2010up patients with negative reverse transcriptase\u2010polymerase chain reaction (RT\u2010PCR) results showed the presence of CD26+ LSCs. Also, there was a strong correlation between CD26+ CML LSCs in the PB and BM (<jats:italic>r<\/jats:italic>\u00a0=\u00a0.917).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Flow cytometric identification of CD26+ LSCs in the peripheral blood can be a cheap, rapid, robust, and potential diagnostic tool for the diagnosis of CML compared to available testing methods.
