An interview with Dr. Funda Meric-Bernstam and Dr. Amber Johnson from the University of Texas MD Anderson Cancer Center in Houston, Texas, and Dr. Mark Robson and Dr. Debyani Chakravarty from Memorial Sloan Kettering Cancer Center in New York, New York, authors on "Somatic Genomic Testing in Patients with Metastatic or Advanced Cancer: ASCO Provisional Clinical Opinion." They discuss the key statements of the provisional clinical opinion, including the topics: multigene panel-based genomic sequencing with disease-specific approved markers, assessment of mismatch repair deficiency and/or microsatellite instability-high status and tumor mutational burden, testing for gene fusions and exon skipping variants, decision making for panel tests with no approved disease-specific markers, and elements to consider while reviewing genomic testing results.
