    Neoadjuvant nivolumab plus ipilimumab in resectable non-small cell lung cancer. (PubMed, J Immunother Cancer)
    Though treatment was feasible, due to toxicity the study arm was terminated early by investigator consensus. In light of this, and while the long-term disease-free status of patients who achieved pCR is encouraging, further investigation of neoadjuvant nivolumab plus ipilimumab in patients with resectable NSCLC requires the identification of predictive biomarkers that enrich for response.

    The Genomic Landscape of SMARCA4 Alterations and Associations with Outcomes in Patients with Lung Cancer. (PubMed, Clin Cancer Res)
    SMARCA4 alterations can be divided into two clinically relevant genomic classes associated with differential protein expression as well as distinct prognostic and treatment implications. Both classes co-occur with KEAP1, STK11, and KRAS mutations, but individually represent independent predictors of poor prognosis. Despite association with poor outcomes, SMARCA4-mutant lung cancers may be more sensitive to immunotherapy.

    [VIRTUAL] Association of KEAP1/NFE2L2 mutations with survival and prediction of immunotherapy in patients with non-small cell lung cancer: Results from multicohort study (AACR-II 2020)
    Intervention of immunotherapy reverses poor prognosis of patients with KEAP1/NFE2L2 mutations due to the higher TMB and neoantigen burden. KEAP1/NFE2L2 mutations maybe potential biomarkers for Immunotherapy in NSCLC.

    [VIRTUAL] Mutational landscape of STK11, PD-L1 expression, and TMB in patients with non-small cell lung cancer (AACR-II 2020)
    The results showed that in our cohort, Chinese NSCLC patients with STK11 GAs were enriched in PD-L1-neg/TMB-H subgroup and associated with a poor response to ICIs in Chinese NSCLC patients. We also found that co-mutations of STK11 and KEAP1 may have implications as a negative biomarker for guiding ICI treatment.
