Leukemia and Lymphoma Phenotyping AlgorithmClinical Background
B-cell non-Hodgkin lymphomas (NHL) represent a heterogenous group of malignancies of the lymphoid system.
Epidemiology
- Incidence -90% of the 755,000 cases of NHL diagnosed yearly
- Age - 60s
- Sex - slight predominance of males
Classification
- Mature B-Cell Neoplasms (WHO classification)
- Diffuse large B-cell lymphoma - 30-40% of NHL
- Follicular lymphoma - 20-25% of NHL
- B-cell chronic lymphocytic leukemia; small lymphocytic lymphoma
- Plasma cell myeloma - plasmacytoma
- Mantle cell lymphoma - 6-8% of NHL
- Splenic marginal zone B-cell lymphoma - rare
- Lymphoplasmacytic lymphoma - rare
- Hairy cell leukemia - rare
- Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type - 8-10% of NHL
- Nodal marginal zone lymphoma (+/- monocytoid B-cells)
- Primary effusion lymphoma - rare
- Burkitt's lymphoma - rare
Risk Factors
- Presence of autoimmune diseases or iatrogenic or acquired immune deficiency
- Sjögren syndrome
- Celiac disease
- Rheumatoid arthritis
- Post-transplant immunosuppression
- Immunosuppressive drugs
- HIV infection
- Inherited disorders
- Chédiak-Higashi syndrome
- Common variable immune deficiency (CVID)
- Wiskott-Aldrich syndrome
- Chronic infection
- Epstein-Barr virus - primary CNS diffuse large B-cell lymphoma
- Helicobacter pylori - gastric mucosa-associated lymphoid tissue (MALT) lymphoma
- Hepatitis C - lymphoplasmacytic lymphoma
- HHV8 - primary effusion lymphomas
Clinical Presentation
- Nonspecific fever, fatigue, weight loss
- Lymphadenopathy (peripheral)

Leukemia and Lymphoma Phenotyping AlgorithmDiagnosis
Diagnosis
- See the Leukemia Lymphoma Immunophenotyping Testing algorithm for specific test ordering recommendations
- Laboratory testing
- Immunophenotyping to identify the malignancy of the lymphoid proliferation and to categorize the lymphoma - flow cytometry testing and immunoperoxidase staining of tissue for specific B-cell antigens or clonality with kappa and lambda light chain staining
- B-cell clonality studies to locate clonal rearrangements of the immunoglobulin gene in B-cell malignancies and to provide information regarding prognosis and treatment recommendations as well as to identify specific molecular translocations that characterize specific NHL subtypes
- Translocation characterizations
- Follicular lymphomas - bcl-2 gene t(14;18)
- Burkitt's lymphoma - Myc gene t(8;14)
- Mantle cell lymphoma - bcl-1 gene t(11;14)
- Non-Hodgkin lymphoma - fluorescent in-situ hybridization (FISH) testing for t(11;14), t(14;18), and c-Myc t(8;14) translocations
- MALT - molecular testing for t(11;14), t(14;18)
- Epstein-Barr virus genome presence in immune suppression (eg, post transplantation) in-situ hybridization testing
- Kappa and lambda light chain clonality in-situ hybridization
- Cytogenetic and FISH studies in myeloma, CLL, and follicular lymphomas -prognostic testing
- Translocation characterizations
