Immunophenotype analysis of chronic lymphocytic leukemia in 31 cases / 中华老年医学杂志

Objective To explore the immunophenotype of chronic lymphocytic leukemia (CLL). Methods The immunophenotypes of 31 patients with CLL were determined by immunocytometry. Results Among 31 cases with CLL, the positive expression rates of CD19,HLA-DR, CD5, CD23, CD20, CD22, CD38, FMC7 and CD10 were 100%, 96.8%, 90.3%,90.3%, 83.9%, 54.8%, 32.3%, 6.5% and 0.0%, respectively. Conclusions The imrnunophenotype analysis is very important for diagnosing CLL and it can early detect monoclonal B-cell lymphocytosis of CLL, which is the early phase of CLL, and provide early warning for patients.
