NGS comprehensive tumor profiling performed by Diagnostic Laboratory Services is a next-generation sequencing assay able to identify known single nucleotide polymorphisms, copy number alterations, transcript fusion mutations, and microsatellite instability to determine matched FDA approved; NCCN guided therapy. Over the past 10 to 15 years, targeted agents have been a fundamental part of therapeutic decision-making. There has been a remarkable improvement in the overall survival of patients where there is a molecular target identified. In 2019, the impact trial was published in the Journal of hematology and oncology. Their look at 3487 patients who underwent tumor profiling showed statistically significant differences in response rate, progression-free survival, and overall survival in months at 3- years and 10- years. Approximately 300,000 patients underwent tumor profiling. At least one treatable molecular variant was found in 1307 patients, who eventually received an associated matched therapy. Objective response rates when there was a match were 16.4% versus 5.4% (p-value <0.0001). Median progression-free survival for matched and unmatched patients was 4.0 and 2.8 months (p-value <0.0001). Overall survival showed differences in matched and unmatched patients, 9.3 versus 7.3 months, with a 3- year survival rate of 15% in matched patients and 7% in unmatched patients. At 10 years, this survival rate was 6% versus 1% ( p-value <0.0001). In multivariate analysis, there was a shorter overall survival in patients with non-matched therapies (p-value <0.001).
