MayoComplete Lung Cancer-Targeted Gene Panel with Rearrangement, Tumor
Use
This test is primarily used for the diagnosis and management of lung cancer, assisting in identifying somatic mutations and gene fusions within specific genes such as ALK, BRAF, EGFR, and others. It evaluates microsatellite instability and can guide the use of targeted therapies by identifying mutations or fusions that respond to specific inhibitors. The test aids in prognostic assessment and potentially determines eligibility for clinical trials, especially for mutations not currently targeted by FDA-approved therapies.
Special Instructions
Not provided.
Limitations
The test does not assess for germline alterations and may not detect multi-exon deletions, duplications, or larger genomic copy number variants. Analytical sensitivity is limited; some variants may be missed if present below detection thresholds. The assay's effectiveness can be compromised by low tumor content or improper tissue treatment, such as decalcification. DNA variants of uncertain significance may be identified, requiring further interpretive context.
