Clinical Analysis of CD4+CD8-T-Cell Large Granular Lymphocytic Leukemia
Objective:To investigate the clinical characteristics and treatment of patients with CD4+CD8-T-cell large granular lymphocytic leukemia(T-LGLL).Methods:The clinical manifestations,diagnosis and treatment of 1 case of CD4+CD8-T-LGLL patient were reported,and relevant literatures were reviewed.Results:The patient was a 70-year-old woman with slow clinical progress,mainly manifested by thrombocytopenia and myelodysplasia.The blood smear was mainly composed of large granular lymphocytes.Immunotyping and T-cell receptor gene rearrangement analysis showed that it was in line with T-LGLL.Partial remission(PR)was achieved through the treatment of cyclophosphamide(50 mg/d)combined with prednisone(gradually reduced and stopped later).Conclusion:CD4+CD8-T-LGLL is very rare in clinical practice,and its clinical manifestations are different from those of CD4-CD8+T-LGLL.
