The mainstay of advanced gastric cancer (GC) therapy is DNA-damaging drugs. Using proteogenomic analysis of a panel of eight GC cell lines, we identified genetic alterations and signaling pathways, potentially associated with resistance to DNA-damaging drugs. Notably, 5-fluorouracil (5FU) resistance was associated with PD-L1 expression, but not established GC subtypes. In publicly available cohort data, PD-L1 expression was associated with a reduced risk of GC progression. In addition to PD-L1, ...
