BACKGROUND: Immunophenotyping of @entity706 becomes necessary for the correct classification, for the design of therapy and for prognosis projection (WHO). Although the spectrum of classic immunohistochemical (IHC) examinations in paraffin embedded or frozen sections has recently considerably extended, IHC should preferably be combined with flow cytometry. The main advantage of flow cytometry is a synchronous application of two or more antibodies marked with various fluorochromes in one sample. The method is limited by utilizing native material only. METHODS AND RESULTS: The flow cytometry combined with histological and IHC investigations were used in diagnosis of primary @entity1893 of B-cell origin ( @entity1893 ) and for bone marrow staging or restaging. We studied 90 @entity1 with confirmed or suspected @entity1893 and we found a good correlation in 89% of samples of primary @entity706 and in 85% of bone marrow samples when IHC and flow cytometry results were compared. The overall efficacy of the flow cytometry determination in lymphoma infiltration of the samples was 89%. CONCLUSIONS: Immunophenotyping utilizing flow cytometry contributes to diagnosis and classification of @entity1892 in the significant proportion of investigated @entity1 . In some cases it is even unnecessary to employ IHC examination of tissue sections. The method is especially suitable for determination of monoclonal populations of B-cells by detection of cell surface markers because it is more specific and sensitive than IHC. The immunophenotyping by flow cytometry as an auxiliary method and in correlation with morphological findings it can make the diagnosis of @entity1892 faster and more specific.
