Tumor mutational burden (TMB) is a novel biomarker and a newly established independent predictor of immune checkpoint inhibitors (ICIs) treatment outcome. TMB is measured as the number of somatic mutations per megabase [Mb] of sequenced DNA. Studies show that patients with a higher number of somatic tumor mutations (TMB-High) are likely to harbor more neoantigen burden, and have been found to have more benefit from ICI therapy compared with patients who had fewer mutations.
The gold standard for measuring TMB has been whole exome sequencing (WES). Taken tissue availability as well as time and cost constrains into consideration, targeted NGS panel with a proper composition of cancer genes is nowadays widely used in routine molecular diagnostics, which requires smaller DNA input amounts and provide a simpler, deeper and faster bioinformatics analysis process, allowing rapid measurement of TMB.
