Enhancing tumor-specific T-cell immunity by inhibiting programmed death ligand 1 (PD-L1)–programmed (PD-1) signaling has shown promise in the treatment of extensive-stage small-cell lung cancer. Combining checkpoint inhibition with cytotoxic chemotherapy may have a synergistic effect and improve efficacy.

Abstract Purpose: The molecular epidemiology of most EGFR and KRAS mutations in lung cancer remains unclear. Experimental Design: We genotyped 3,026 adenocarcinomas for the major (exon 19 deletions L858R) (G12, G13) examined correlations with demographic, clinical, smoking history data. Results: were found 43% never smokers 11% smokers. occurred 34% 6% In patients histories up to 10 pack-years, predominated over KRAS. Among former cancer, multivariate analysis showed that, independent...

Purpose Advanced anaplastic lymphoma kinase ( ALK) fusion-positive non-small-cell lung cancers (NSCLCs) are effectively treated with ALK tyrosine inhibitors (TKIs). However, clinical outcomes in these patients vary, and the benefit of TKIs is limited as a result acquired resistance. Emerging data suggest that fusion variant may affect outcome, but molecular basis for this association unknown. Patients Methods We identified 129 ALK-positive NSCLC known variants. resistance mutations on were...

PURPOSE The open-label, phase III POSEIDON study evaluated tremelimumab plus durvalumab and chemotherapy (T + D CT) (D versus alone (CT) in first-line metastatic non–small-cell lung cancer (mNSCLC). METHODS Patients (n = 1,013) with EGFR/ ALK wild-type mNSCLC were randomly assigned (1:1:1) to 75 mg 1,500 platinum-based for up four 21-day cycles, followed by once every 4 weeks until progression one additional dose; progression; or six cycles (with without maintenance pemetrexed; all arms)....
