Detection of fluorescent probe binding by the cells requires the use of flow cytometry preferably employing 6 to 8 different fluorescent probes that bind to different markers on 5 million cells from the patient's blood. The table also includes the percentage of MLB cases with the phenotype and the malignancies to which they progress.
The whole procedure can be performed on cells from the blood, bone marrow or spinal fluid in a matter of a few hours. [citation needed] Immunophenotyping is a very common flow cytometry test in which fluorophore-conjugated antibodies are used as probes for staining target cells with high avidity and affinity.
Lymphocytosis is usually detected when a complete blood count is obtained. If not provided the lymphocyte count can be calculated by multiplying the total white blood cell (WBC) count by the percentage of lymphocytes found in the differential count. [13] The lymphocyte count can also be directly measured by flow cytometry. [citation needed]
Flow cytometry (FC) is a technique used to detect and measure the physical and chemical characteristics of a population of cells or particles. [1] [2] [3] [4]In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument.
Treatment may involve one or more of the following: chemotherapy, radiation therapy, proton therapy, targeted therapy, and surgery. [1] [2] In some non-Hodgkin lymphomas, an increased amount of protein produced by the lymphoma cells causes the blood to become so thick that plasmapheresis is performed to remove the protein. [2]
Further information about the specimen may be gained by immunohistochemical stains and molecular testing, particularly if the sample is prepared using liquid based cytology. Often "reflex" testing is performed, such as HPV testing on an abnormal pap test or flow cytometry on a lymphoma specimen.
Splenic marginal zone lymphoma (SMZL) is a type of marginal zone lymphoma, a cancer made up of B-cells that replace the normal architecture of the white pulp of the spleen. The neoplastic cells are both small lymphocytes and larger, transformed lymphoblasts , and they invade the mantle zone of splenic follicles and erode the marginal zone ...
Micrograph showing Hodgkin's lymphoma, a type of B cell lymphoma that is usually considered separate from other B cell lymphomas. Field stain. CT scan of primary B cell lymphoma in the left ilium, as diffuse cortical and trabecular thickening of the hemipelvis, mimicking Paget's disease. [2] There are numerous kinds of lymphomas involving B cells.
