Orderable Test Description

This panel is designed to detect specific genetic abnormalities commonly associated with non-Hodgkin lymphoma (NHL) and related B-cell lymphomas including B-cell lymphoma, mantle cell lymphoma (MCL), follicular lymphoma, marginal zone lymphoma (MZL), and MALT lymphoma. It includes the following probes: 

BCL6 (3q27) 
CCND1/IgH t(11;14) 
IgH/BCL2 t(14;18) 
MALT1 (18q21) 

Test Customization: Probes for each translocation may be ordered separately.

Clinical Significance

This targeted panel is appropriate when clinical and morphologic evaluation is most suggestive of a low-grade/small B-cell lymphoma, and high-grade lymphomas (such as large cell anaplastic and Burkitt lymphoma) are not a diagnostic consideration. BCL6 evaluation (included in this panel) can provide further prognostic information in cases of follicular lymphoma since it can indicate a higher risk for transformation to aggressive lymphoma.

Low-grade/small B-cell lymphomas include follicular lymphoma, mantle cell lymphoma (MCL), and marginal zone lymphoma (MZL)/MALT lymphomas. Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is also within this category, but typically has a peripheral blood lymphocytosis and is better evaluated by the CLL FISH Panel or NeoTYPE CLL Profile.

Storage and transportation

Use cold pack for transport, making sure cold pack is not in direct contact with specimen. For fresh samples: refrigerate before shipping and ship same day as drawn whenever possible. Do not freeze. NYS clients please provide date and time of collection.
