Oncology FISH Analysis - MYC Translocation

Clinical Use

Use

Oncology FISH Analysis - MYC Translocation is a Fluorescence In Situ Hybridization (FISH) test designed to detect a common chromosomal translocation associated with Burkitt's lymphoma (BL). This malignancy is a form of non-Hodgkin's lymphoma that primarily arises from lymph cells and is prevalent in children and young adults. The test identifies the LSI MYC: t (8; ?) translocation, which occurs in approximately 75-90% of Burkitt's lymphoma cases. The test results should be interpreted considering relevant clinical and pathological data and are not meant to serve as a stand-alone diagnostic tool.

Special Instructions

Specimens for this test must be collected properly, ensuring the type of tube and conditions are met. Shipping must occur within specific temperature ranges to maintain specimen integrity. Results should be interpreted in conjunction with other clinical data, adding contextual relevance to the findings. Specifically, adequate amounts of tissue or bone marrow are vital to ensure reliable test results, influencing therapeutic direction and clinical outcomes.

Limitations

The FISH assay specifically tests for rearrangements at the MYC locus but does not identify partner chromosomes involved in the abnormality. This limitation can affect the comprehensive understanding of the chromosomal landscape in Burkitt's lymphoma, as knowing all partners can be critical for accurate diagnosis and treatment planning. Results should always be validated with clinical findings and other diagnostic modalities as necessary.
