Electromagnetic Navigation Bronchoscopy for Peripheral Pulmonary Lesions: One-Year Results of the Prospective, Multicenter NAVIGATE Study.
Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology that guides endoscopic tools to pulmonary lesions. ENB has been evaluated primarily in small, single-center studies; thus, the diagnostic yield in a generalizable setting is unknown. ⋯ NAVIGATE shows that an ENB-aided diagnosis can be obtained in approximately three-quarters of evaluable patients across a generalizable cohort based on prospective 12-month follow-up in a pragmatic setting with a low procedural complication rate.

The present review is an update of the research and development efforts regarding the use of molecular biomarkers in the lung cancer screening setting. The two main unmet clinical needs, namely, the refinement of risk to improve the selection of individuals undergoing screening and the characterization of undetermined nodules found during the computed tomography-based screening process are the object of the biomarkers described in the present review. We first propose some principles to optimize lung cancer biomarker discovery projects. ⋯ We also underline the importance of integrating different molecular technologies together with imaging, radiomics, and artificial intelligence. We list a number of completed, ongoing, or planned trials to show the clinical utility of molecular biomarkers. Finally, we comment on future research challenges in the field of biomarkers in the context of lung cancer screening and propose a design of a trial to test the clinical utility of one or several candidate biomarkers.

With increasing use of immune checkpoint inhibitors (ICIs) for advanced NSCLC, there is increasing recognition of immune-related adverse events associated with ICI use. We recently reported increased incidence of checkpoint inhibitor pneumonitis (CIP) in ICI-treated NSCLC patients. Since development of immune-related adverse events in other organ systems has been associated with either no change or even improvement in tumor response/cancer outcomes, we sought to better understand the impact of CIP development on overall survival in ICI-treated NSCLC patients. ⋯ We found that developing CIP independently increased the risk of transitioning to death in both adjusted and unadjusted models. In the multivariate model, we found that the increase in mortality associated with CIP was only seen in patients with adenocarcinoma tumor histology. Collectively, these findings suggest that in NSCLC, development of CIP worsens survival in patients receiving immunotherapy.
