    Overcoming CEP85L-ROS1, MKRN1-BRAF and MET amplification as rare, acquired resistance mutations to Osimertinib. (PubMed, Front Oncol)
    The first patient presented with EGFR L858R/L833V compound mutation with MET amplification alongside CEP85L-ROS1 fusion gene, the second with EGFR exon 19del and MKRN1-BRAF fusion, and the last EGFR L858R/V834L compound mutation with MET amplification. Each regimen utilized a tyrosine kinase inhibitor or monoclonal antibody in addition to osimertinib and allowed for a prompt and relatively durable treatment response.

    Response with pemrbolizumab in a patient with EGFR mutated non-small cell lung cancer harbouring insertion mutations in V834L and L858R. (PubMed, J Oncol Pharm Pract)
    From our observation Pembrolizumab could be promising in patients with rare EGFR mutations who do not respond to EGFR directed therapy. Our report provides supporting data for the use of immunotherapies in patients with EGFR mutated NSCLC.

    Acquired resistance to osimertinib in patients with non-small-cell lung cancer: mechanisms and clinical outcomes. (PubMed, J Cancer Res Clin Oncol)
    The study revealed heterogeneous mechanisms of resistance to osimertinib in advanced NSCLC patients and their association with clinical outcomes. Patients who maintained T790M mutation or with EGFR-dependent resistance mechanism had longer clinical outcome benefits.
