Mantle Cell Lymphoma FISH Panel
Methodology
FISH
Test Description and clinical significance
Probes
11q13.3/14q32.33
Disease:
Mantle cell lymphoma
Detection of CCND1/IGH translocation. The t(11;14)(q13;q32) translocation results in the CCND1 gene being inserted into the heavy chain (IGH) locus resulting in over production cyclin D1 protein4. IGH-CCND1 Fusion, t(11;14) by FISH is described in many hematologic malignancies.
Specimen Requirements
Collection:
The ordering pathologist will decide whether to order a conventional FISH preparation or a B-cell enrichment (BCE) FISH preparation.
Bone Marrow Aspirate: 1~2mL in Green top (Sodium Heparin) tube OR Lavender top (EDTA) tube. B-cell enrichment eligible.
Peripheral Blood: 2~5mL Green top (Sodium Heparin) tube OR Lavender top (EDTA) tube. B-cell enrichment eligible.
Fresh, Unfixed Tissue: Tissue in RPMI. A conventional FISH preparation will be performed as B-cell enrichment can not be performed on fresh tissues.
Fluids: Equal parts RPMI to specimen volume. A conventional FISH preparation will be performed as B-cell enrichment can not be performed on fresh fluid tissues.
Paraffin Block: H&E slide and paraffin block. B-cell enrichment can not be performed on paraffin embedded tissues.
Cut Slides: H&E slide and 1 unstained slide (cut at 4 microns) per probe. B-cell enrichment can not be performed on paraffin embedded tissues.
Stability:
120 Hours
Unacceptable Conditions:
DO NOT FREEZE
Storage & Transport
