Improved Detection of Diffuse Large B-Cell Lymphoma by Flow Cytometric Immunophenotyping-Effect of Tissue Disaggregation Method

摘要

Background: Flow cytometric immunophenotyping (FCI) is recognized as a rapid, sensitive, and accurate method for diagnosis of B-cell lymphomas. We observed that FCI failed to identify the clonal B-cell population in several cases of large B-cell lymphoma (DLBCL) when tissue samples were prepared by a commercially available mechanical tissue disaggregation method. We tested a manual tissue disaggregation method and compared it with the mechanical method.
