    Second-line immunosuppressant administration for steroid-refractory immune-related adverse events in patients with lung cancer

    Evidence for use of second-line immunosuppressants for immune-related adverse events (irAEs) is inadequate. Therefore, a multicenter analysis should assess the efficacy of second-line immunosuppressants for se...

    Subsequent treatment for locally advanced non-small-cell lung cancer that progressed after definitive chemoradiotherapy and consolidation therapy with durvalumab: a multicenter retrospective analysis (TOPGAN 2021-02)

    For patients with locally advanced non-small-cell lung cancer (LA-NSCLC) that progressed after definitive chemoradiotherapy (CRT) and durvalumab consolidation therapy, no subsequent standard treatment exists. ...

    Soluble interleukin-2 receptor as a predictive biomarker for poor efficacy of combination treatment with anti-PD-1/PD-L1 antibodies and chemotherapy in non-small cell lung cancer patients

    Soluble interleukin-2 receptor (sIL-2R) suppresses effector T-cells. Few studies have assessed serum sIL-2R in patients receiving immunotherapy. We evaluated the association between serum sIL-2R levels and the...

    Myocarditis associated with immune-checkpoint inhibitors diagnosed by cardiac magnetic resonance imaging

    Myocarditis associated with immune-checkpoint inhibitors (ICIs) is a rare, but critical adverse event. Although endomyocardial biopsy (EMB) is the standard for diagnosis of myocarditis, there is a possibility ...

    EGFR-TKI re-administration after osimertinib failure in T790M mutation loss cases with re-biopsy

    Data on the re-administration of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) after osimertinib failure in patients with T790M-positive non–small cell lung cancer (NSCLC) is limite...

    Microsecond-timescale MD simulation of EGFR minor mutation predicts the structural flexibility of EGFR kinase core that reflects EGFR inhibitor sensitivity

    Approximately 15–30% of patients with lung cancer harbor mutations in the EGFR gene. Major EGFR mutations (>90% of EGFR-mutated lung cancer) are highly sensitive to EGFR tyrosine kinase inhibitors (TKIs). Many un...

    Phase II study of the combination of S-1 with bevacizumab for patients with previously treated advanced non-squamous non-small-cell lung cancer

    We assessed the efficacy and safety of bevacizumab and S-1 chemotherapy for patients with previously treated advanced non-squamous non-small-cell lung cancer (NSCLC).

    Efficacy of EGFR tyrosine kinase inhibitors in patients having EGFR-activating mutations with or without BIM polymorphisms

    Patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer with BIM deletion polymorphism may have a limited response to EGFR tyrosine kinase inhibitors (EGFR-TKIs). However, some re...

    Susceptibilities of medaka (Oryzias latipes) cell lines to a betanodavirus

    Betanodaviruses, members of the family Nodaviridae, have bipartite, positive-sense RNA genomes and are the causal agents of viral nervous necrosis in many marine fish species. Recently, the viruses were shown to ...
