HLA-G and B-cell chronic lymphocytic leukemia: Among CLL patients, there was a weak positive correlation between the percentage of M-MDSC and the white blood cells (WBC) count (r = 0.262, p < 0.05) and peripheral blood (PB) lymphocyte count (r = 0.270, p < 0.05); no correlations were identified for the platelet counts, haemoglobin concentration, serum lactate dehydrogenase (LDH), and β2-microglobulin levels or the ages of the patients.
