Testing Methodologies and Standards in Metastatic NSCLC

Panelists discuss the various tests available for detecting genetic mutations in advanced non–small cell lung cancer (NSCLC), including next-generation sequencing (NGS), reverse transcription polymerase chain reaction (RT-PCR), fluorescence in situ hybridization (FISH), immunohistochemistry (IHC), and Sanger sequencing, and explore whether one method is considered the “gold standard” according to the NCCN guidelines. They also address the appropriate use of circulating tumor DNA (ctDNA) testing, comparing it to tissue testing in this disease state.
