    Molecular Characteristics and Response to TKIs in NSCLC Patients with EGFR Exon 19 Insertions (IASLC-WCLC 2023)
    Results from in vitro experiments suggested that the EGFR I740_K745dup mutation might be more sensitive to afatinib. Our comprehensive analysis of EGFR 19ins in lung cancer patients revealed genomic characteristics and clinical response that are distinct from 19del/delins. Our findings help better inform clinical action and might facilitate the development of more precise therapeutic options for patients with these uncommon driver mutations.

    EGFR exon 19 insertion EGFR-K745_E746insIPVAIK and others with rare XPVAIK amino-acid insertions: Preclinical and clinical characterization of the favorable therapeutic window to all classes of approved EGFR kinase inhibitors. (PubMed, Lung Cancer)
    This is the largest preclinical/clinical report to highlight that EGFR-K745_E746insIPVAIK and other mutations with exon 19 XPVAIK amino-acid insertions are rare but sensitive to clinically available 1st, 2nd, and 3rd generation as well as EGFR exon 20 active TKIs; in a pattern that mostly resembles the outcomes of models with EGFR-L861Q and EGFR-A763_Y764insFQEA mutations. These data may help with the off-label selection of EGFR TKIs and clinical expectations of outcomes when targeted therapy is deployed for these EGFR mutated lung cancers.

    Uncommon single and compound EGFR mutations: clinical outcomes of a heterogeneous subgroup of NSCLC. (PubMed, Curr Probl Cancer)
    For mutations in exon 18 (not in codon 719) and exon 20 insertions, chemotherapy seems the most effective available option. The addition of immunotherapy to chemotherapy could change this approach in the next future.
