    Circulating tumor DNA profiling and serial analysis in salivary gland carcinomas reveal unique mutational subsets and actionable alterations. (ASCO 2022)
    Blood-based liquid biopsy can be applied in salivary gland tumors to detect genomic alterations in ctDNA which may provide opportunities for therapeutic intervention in a cancer with limited treatment options. Additionally, ctDNA testing may be used to identify resistant alterations to potential therapy. Finally, longitudinal assessment of ctDNA may shed light on tumor evolution and additional therapeutic targets may be found.

    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.

    [VIRTUAL] Molecular characterization and prognostic analysis of non-small cell lung cancer: A single centric real-world study. (ASCO 2020)
    Only one patient of this group received immunotherapy with pembrolizumab and achieved SD at the 2nd month... More than half of NSCLC patients have targetable genetic variants and more than 30% patients have a molecular signature that can be treated with immunotherapy. Compared with immunotherapy, targeted therapy has higher acceptability in real-world. NGS-based genetic testing may have clinical value to predict the effectiveness of targeted therapy and immunotherapy.

    [VIRTUAL] Clinical and patho-genomic characteristics of concomitant mutated status of TP53, EGFR, KRAS genes in Chinese patients with resected lung adenocarcinoma. (ASCO 2020)
    TP53,EGFR and KRAS mutations and their concomitant mutation status displayed diverse correlation with spatial, clinical and genomic characteristics in resectable LUAD patients. This correlation may indicate complex biological heterogeneity of LUAD which may need further exploration. Research Funding: None
