Lymphoma FISH testing (FFPE)

Diagnostic Use

High-grade B-cell Lymphomas were redefined into two distinct categories in the 2017 WHO classification of Tumours and Haematopoietic and Lymphoid Tissues.

The first category, High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, encompasses all B-cell lymphomas that have MYC rearrangement in combination with a BCL2 and/or BCL6 rearrangement.
The second category, High-grade B cell lymphoma, NOS, lack the double or triple hit.

Specimen Requirements

Tube/Container Type:

Preferred

• Slide(s)

Pre-testing Requirements

Only tissue preserved in neutral buffered formalin and paraffin embedded is suitable for use.
NB: Samples de-calcified in formic acid are not suitable for FISH as this process affects the integrity of the DNA
Tissue specimens should be cut into sections of 2-4µm, on poly-L-lysine slides.
The H&E slide must be assessed by a pathologist prior to receipt and appropriate areas for FISH analysis clearly marked.

Ensure one H&E slide and 5~8 unprocessed slides are supplied.
Slide must be clearly labelled with two patient identifiers, matching those on the request form.

Aliquot Instructions

Transport to Lab

Ambient (8 - 24 degrees Celsius)

Additional Referral/Aliquot Information

Transport in slide-holders or boxes, at ambient temperature

Interpretation

Clinically significant rearrangements and copy number changes outside of established normal ranges will be reported with relevant interpretive comment.

Test Method

Fluorescent in situ hybridisation (FISH) on formalin fixed paraffin embedded (FFPE) tissue.

Tests available:

MYC Rearrangement
IGH/MYC gene fusion
BCL2 Rearrangement
BCL6 Rearrangement
IGH/BCL2 gene fusion

The same probes may be applied to a standard blood or bone marrow preparation if required. See 'Haematological and Oncological FISH'
