結(jié)論:高TMB不能保證受益于免疫檢查點抑制(ICI)
Current status of immune checkpoint inhibitors for gastric cancer | SpringerLink
In addition, high tumor mutational burden (TMB) [73], T-cell inflamed gene profiling and interferon-γ gene signature [74], and circulating tumor DNA (ctDNA) [75] have been also reported as possible biomarkers predicting clinical outcomes of immunotherapy by ICI

腫瘤突變負擔作為胃癌PD-1抗體治療的新生物標志物 (nih.gov)
腫瘤突變負擔(TMB)最近已被描述為PD-1抗體治療的一種新的生物標志物。但是变抽,其在AGC中的預(yù)測作用尚未得到證實。在最近發(fā)表于《腫瘤學年鑒》上的一項研究中雏节,Wang等人嘶摊。[ 9 ]已將TMB鑒定為用托利帕單抗治療的難治性胃癌OS獲益的生物標志物曼追。作者通過使用全外顯子組測序(WES)測試了TMB栅受,發(fā)現(xiàn)TMB而非PD-L1與AGC的顯著生存獲益相關(guān)族铆。TMB-High組的OS明顯優(yōu)于TMB-Low組(14.6 vs 4.0個月岩四,HR = 0.48,P ?= 0.038)哥攘。這項研究是第一個將TMB識別為ICI在胃腸道(GI)癌癥中使用的預(yù)測性生物標志物剖煌。
