Abstract
Flow cytometry is an invaluable technology in the examination of blood, bone marrow, tissue and body fluids for the presence or absence of hematological disease. It is used in both diagnostic and follow-up testing, with an increasingly important role in the detection of very small residual disease populations (Minimal Residual Disease, MRD) However, flow cytometry immunophenotyping of leukemia and lymphoma is highly dependent on interpretation of results and with the increased complexity of 8-10 color instruments routinely used in clinical laboratories, knowledge of disease-defining populations is increasingly important as is recognizing normal and reactive patterns. This manuscript presents case studies with flow cytometric patterns encountered in routine screening of samples sent for leukemia and lymphoma immunophenotyping, focusing mainly on B-cell disorders which may be missed or incorrectly interpreted by the laboratory (including a hematopathologist) performing the test. Case studies are used to illustrate our laboratory's standardized approach to the interpretation of flow cytometric data. In addition to a standardized approach, these cases emphasize the importance of interpretative skills of technologist and hematopathologists in recognizing abnormal patterns in detecting hematological malignancies.

Abstract
Multiparameter flow cytometric analysis allows for precise evaluation of growth factor stimulated intracellular signaling in distinct immunophenotype defined hematopoetic populations. Our analysis of intracellular phosphoprotein in response to major hematopoietic growth factors or cytokines showed several interesting findings. Although there was no characteristic signaling abnormality that was diagnostic for MDS, MDS cases were often associated with more signaling aberrancies involving more cellular populations. Higher than average response in the CD34(+)CD117(+) progenitor cells to Flt3 ligand and stem cell factor stimulation was frequently associated with high risk features or disease progression in MDS. Although preliminary results hint an adverse prognostic role of dysregulated FLT3 pathway in MDS cases, whether this observation adds independent prognostic value to the existing prognostic system needs to be further explored in future prospective studies.

Abstract
Within the last 25 years, flow cytometry and fluorescence-activated cell sorting have emerged as both routine diagnostic tools in clinical medicine and as advanced analytic tools critical in performing scientific research. This chapter aims at summarizing the use of flow cytometry in benign and malignant hematology and the monitoring of inherited and acquired immunodeficiency states. Numerous figures are provided from our laboratories at Massachusetts General Hospital that illustrate examples of these conditions. The chapter also describes novel flow cytometry-based imaging techniques, the combination of flow cytometry and mass spectrography, new software tools, and some future directions and applications of advanced instrumentation for flow cytometry.

Abstract
Lenalidomide (LEN) treatment in multiple myeloma (MM) results in a superior outcome. However, there is concern for increased myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) associated with LEN. Thus, bone marrow morphology and cytogenetics studies from 40 patients were evaluated for early signs of MDS prior to therapy, during therapy and at follow-up. Newly diagnosed patients with MM treated with LEN and dexamethasone (LD) alone or followed by autologous stem cell transplant (LD/ASCT), or patients with relapsed/refractory MM treated with LEN, bendamustine and dexamethasone (BLD) were included. One patient developed MDS. Baseline prevalence of mild morphologic myelodysplasia was highest in pretreated patients with MM (BLD, 71%), but was also seen in newly diagnosed patients (LD and LD/ASCT, 17%). The prevalence of myelodysplasia did not increase over time. Thus, this study did not reveal rapidly emerging MDS in 39 of 40 patients with MM treated with LEN. The development of MDS in one patient suggests that longer follow-up is needed for all.
