The modified Matutes score has been the basis for the diagnosis of chronic lymphocytic leukaemia (CLL) by flow cytometry for the past 15 years. To increase the specificity of the current score we systematically evaluated the diagnostic value of established as well as novel markers, such as CD200, in a large cohort of patients with untreated B-cell malignancies (n = 370). Double positivity for CD5 and CD23 was of very high value to differentiate between CLL and non-CLL cases. In addition, lack of FMC7 expression as well as CD79b expression intensity showed high sensitivity (90·4% and 92·3%) with acceptable specificity (74·4% and 76·9%). For surface IgM, low or absent expression displayed poor specificity in distinguishing CLL from non-CLL cases (51,3%; sensitivity 83,7%). Finally, CD200 positivity showed high sensitivity and specificity. Therefore, CD5/CD23, FMC7, CD79b and CD200 were included in our new CLLflow score, which retained high sensitivity (97·1% vs. 98·6% for the Matutes score, P = 0·38), but showed markedly increased specificity (87·2% vs. 53·8%, P < 0·001). These results were confirmed in our validation cohort (sensitivity 97·0% vs. 100%, P = not applicable; specificity 86·4% vs. 59·1%, P = 0·03). Our data support the use of our new CLLflow score for the diagnosis of CLL with significantly higher specificity.

D015451 Leukemia, Lymphocytic, Chronic, B-Cell A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma.
