Abstract
Introduction: Changes in the number and functional capacity of T-lymphocytes have been reported in chronic lymphocytic leukemia (CLL) patients. The aim of this study was to examine the prognostic significance of T-lymphocyte subgroups in CLL patients.
Methods: Eighty-three previously untreated patients were retrospectively enrolled and flow cytometry results at diagnosis were examined. No difference was found in T-lymphocyte parameters according to age, gender, and disease stage.
Results: The CD4 and CD7 percentages, CD4/MBC (Malignant B Cell), CD8/MBC, and CD7/MBC values at diagnosis were significantly lower in patients with a progressive disease. T-lymphocyte percentages were significantly lower in deceased patients. In the univariate regression model, T-lymphocyte percentages, T-lymphocyte/MBC ratios, HLA-DR+ percentage, Rai stage (intermediate + high risk), Binet stage (B+C), and beta-2 microglobulin level had significant effects on both progression-free survival (PFS) and overall survival (OS); treatment status (yes) had a significant effect only on PFS, while age at diagnosis (≥ 65 years) had a significant effect only on OS. In the multivariate regression model, Rai stage, CD7/MBC ratio, and treatment status (yes) had a significant effect on PFS; Rai stage and CD8/MBC ratio had a significant effect on OS.
Conclusion: Lower T-lymphocyte/MBC ratios at diagnosis could be a marker for higher risk of CLL progression.
期刊介绍:
''Acta Haematologica'' is a well-established and internationally recognized clinically-oriented journal featuring balanced, wide-ranging coverage of current hematology research. A wealth of information on such problems as anemia, leukemia, lymphoma, multiple myeloma, hereditary disorders, blood coagulation, growth factors, hematopoiesis and differentiation is contained in first-rate basic and clinical papers some of which are accompanied by editorial comments by eminent experts. These are supplemented by short state-of-the-art communications, reviews and correspondence as well as occasional special issues devoted to ‘hot topics’ in hematology. These will keep the practicing hematologist well informed of the new developments in the field.
