TMB is linked with prognosis Nature Reviews Clinical Oncology

WebTumor mutational burden (TMB) is an assessment of the number of somatic mutations in a defined region of a tumor genome and varies according to tumor type as well as among patients. Tumors with high levels of TMB are more likely to produce tumor cell surface epitopes that act as neoantigens and induce an elevated antitumor immune response. WebTMB is a measure of the number of mutations carried by tumor cells. Tumors with many mutations have a high mutational burden (high TMB). Many of the tumors with high TMB are also MSI-H or microsatellite instability high. Approximately 3% of tumors classified as MSS (microsatellite stable) also have high TMB. aeropenta
