    Inter- and Intratumor Heterogeneity of EGFR Compound Mutations in Non-Small Cell Lung Cancers: Analysis of Five Cases. (PubMed, Clin Lung Cancer)
    No intra- or intertumor heterogeneity was observed for EGFR compound mutations. Our results indicate that both EGFR mutations were truncal and selective elimination of cancer cells with uncommon EGFR mutations is unrealistic.

    Clinical Benefit of Tyrosine Kinase Inhibitors in Advanced Lung Cancer with EGFR-G719A and Other Uncommon EGFR Mutations. (PubMed, Oncologist)
    Afatinib treatment at 40 mg daily is associated with high rates of adverse events and dose reductions; alternative strategies including pulse intermittent dosing should be evaluated prospectively. Osimertinib (with favorable safety profile and intracranial penetration) has shown promising results in this population in a phase II trial from South Korea; additional trials are ongoing.

    [VIRTUAL] Prevalence of uncommon epidermal growth factor receptor (EGFR) alterations detected in circulating tumor DNA (ctDNA) of non-small cell lung cancer (NSCLC) patients from East Asia. (ASCO 2020)
    "Uncommon, potentially actionable EGFR mutations were found in 9% of plasma samples from East Asian NSCLC patients. In this clinical practice dataset, uncommon EGFR mutations were more prevalent than actionable biomarkers in other genes. These data support the use of NGS testing methods to identify NSCLC patients for appropriate EGFR-targeted therapy."
