Abstract:
The study of the expression level by lymphoma cells (MFI: mean fluorescence intensity) completed by ROC curve for diagnostic markers is a valuable aid for the daily interpretation of lymphocyte immunophenotyping as well as the differential diagnosis with other chronic lymphoproliferative B syndromes. The aim is to provide diagnostic guidance, increase the power of the diagnostic test based on the discriminating capacity of each marker and validate the value of the Matutes score adapted to our study population. Materials and Methods: This is a technical validation study with retrospective recruitment of 91 patients diagnosed with B-CLL according to clinical, cytological and biological results. Statistical analysis is performed by the SPSS software. Results: The ROC curve shows the discriminative power of each diagnostic marker. The combination of discriminatory markers (CD23, CD5, CD43) either in double or triple marking did not increase the power of the test; The diagnosis of B-CLL according to our threshold values is changed to a score value greater than or equal to 3. Conclusion: The analysis of each marker, using the ROC curve allows us to identify the most discriminating markers useful to orient the diagnosis by elaborating a diagnostic score
