Responses to ICIs in NSCLC patients with EGFR 19del, L858R, T790 M and EGFR ex20ins have also been evaluated, including patients with the common EGFR exon del 19 or L858R mutation who exhibited ORRs to ICI <20% and PFS less than 3.5 months (17). Here, EGFR is linked to non-small cell lung carcinoma.
