Brigatinib is a next-generation ALK inhibitor initially developed in ALK-positive NSCLC pretreated with crizotinib. ⋯ These real-world results confirm the efficacy of brigatinib in a cohort of patients heavily pretreated for ALK-positive advanced NSCLC.

This study aimed to assess the cost-effectiveness of pembrolizumab monotherapy compared with chemotherapy as first-line treatment in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) with different tumor proportion scores (TPS), from perspectives of payers in China. ⋯ ICERs yield by pembrolizumab monotherapy among different TPS populations were beyond the threshold we set, three times of the Gross Domestic Product per Capita of China in 2018 ($26,508/QALY). It is not a cost effective choice compared with standard chemotherapy for patients with locally advanced or metastatic NSCLC from the perspective of Chinese payer, regardless of TPS. Deeper discount of its current price would make pembrolizumab a preferable choice.

The treatment for stage III non-small cell lung cancer (NSCLC) is quite variable because stage III NSCLC is a heterogenous disease. Programmed death ligand 1 (PD-L1) and CD8+ tumor infiltrating lymphocytes (TILs) are thought to be related to treatment outcome in many tumors. To improve treatment outcome in stage III NSCLC, it is necessary to obtain data on PD-L1 expression and CD8+ TIL counts following CCRT and their relationship to treatment outcome. ⋯ CCRT dynamically alters PD-L1 expression and CD8+ TIL numbers in stage III NSCLC. Our data provide a rationale for combining CCRT and immunotherapy for the treatment of potentially resectable NSCLC.

Lung cancer screening with low dose computed-tomography (LDCT) is currently recommended for high-risk populations based on mortality benefit shown in the National Lung Screening Trial (NLST). This study evaluated performance of a community-based lung cancer screening program in a Histoplasma endemic region. ⋯ Baseline positive screens in our study are similar to NLST data with Lung-RADS criteria implementation (14.6% vs 13.6%, p = 0.15) despite being a Histoplasma endemic region. Our study shows a successful performance of a community-based lung cancer screening program in a Histoplasma endemic region.

The aim of this phase 1/2 study was to evaluate the safety, tolerability, pharmacokinetics and antitumor activity of olmutinib in patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) who had failed ≥ 1 previous line of EGFR-tyrosine kinase inhibitor (TKI) therapy. ⋯ Olmutinib showed effective clinical activity with a manageable safety profile, indicating therapeutic potential for T790M-positive NSCLC patients who have failed ≥ 1 previous line of EGFR-TKI therapy.
