A recent study in vivo showed that EGFR E746-A750 deletion mutant lung cancer can induce DC anergy and inhibit antitumor immunity, while T-cell infiltration and DC function were restored; meanwhile, the efficacy of ICIs in EGFR-19del tumors was improved because of the use of TKIs in combination with granulocyte-macrophage colony-stimulating factor (78). The gene discussed is EGFR; the disease is lung carcinoma.
