Background: Higher tumor mutation burden (TMB) in advanced non-small cell lung cancer (NSCLC) is associated with superior outcomes with checkpoint inhibitor therapy. Tissue samples subject to TMB analysis may be acquired after DNA-damaging therapies such as chemotherapy or radiation. The impact of these therapies on TMB results is unclear. This retrospective analysis explored differences in TMB among treatment-naïve samples and treatment-experienced samples.
