Abstract
Flow cytometry has been indispensable in diagnosing B cell lymphoma and plasma cell neoplasms. The advances in novel multicolor flow cytometry have also made this technology a robust tool for monitoring minimal/measurable residual disease in chronic lymphocytic leukemia and multiple myeloma. However, challenges using conventional gating strategies to isolate neoplastic B or plasma cells are emerging due to the rapidly increasing number of antibody therapeutics targeting single or multiple classic B/plasma cell-lineage markers, such as CD19, CD20, and CD22 in B cells and CD38 in plasma cells. This review is the first of a two-part series that summarizes the most current targeted therapies used in B and plasma cell neoplasms and proposes detailed alternative approaches to overcome post-targeted therapy analysis challenges by flow cytometry. The second review in this series (Chen et al.) focuses on challenges encountered in the use of targeted therapy in precursor B cell neoplasms.
期刊介绍:
Cytometry Part B: Clinical Cytometry features original research reports, in-depth reviews and special issues that directly relate to and palpably impact clinical flow, mass and image-based cytometry. These may include clinical and translational investigations important in the diagnostic, prognostic and therapeutic management of patients. Thus, we welcome research papers from various disciplines related [but not limited to] hematopathologists, hematologists, immunologists and cell biologists with clinically relevant and innovative studies investigating individual-cell analytics and/or separations. In addition to the types of papers indicated above, we also welcome Letters to the Editor, describing case reports or important medical or technical topics relevant to our readership without the length and depth of a full original report.
