Abstract
Immunophenotyping plays a major role and is essential for establishing the diagnosis of chronic lymphocytic leukemia (CLL). Though CLL has a characteristic phenotype, diagnosis may be challenging due to immunophenotypic overlap with other B cell non-Hodgkin's lymphomas (B-NHL). Markers like CD200, CD43, CD20 and CD45 were found valuable in CLL and we investigated their diagnostic efficiency and accuracy in 174 patients with leukemic B-NHL. On the integration of four markers by a scoring system, 96% (49/51) of CLL cases showed a score of 3 or 4 and 90% (36/40) of non-CLL cases had a score of 0 or 1. This scoring system for CLL diagnosis showed a sensitivity of 98.2% and 96% in the analytical cohort and validation cohort respectively, which was significantly higher than the classical Matutes score. Hence we strongly suggest considering the expression of CD200, CD20, CD43 and CD45 in the diagnosis of B-NHL cases.
期刊介绍：
Leukemia & Lymphoma in its fourth decade continues to provide an international forum for publication of high quality clinical, translational, and basic science research, and original observations relating to all aspects of hematological malignancies. The scope ranges from clinical and clinico-pathological investigations to fundamental research in disease biology, mechanisms of action of novel agents, development of combination chemotherapy, pharmacology and pharmacogenomics as well as ethics and epidemiology. Submissions of unique clinical observations or confirmatory studies are considered and published as Letters to the Editor
