Utility of Maximum Standard Uptake Value as a Predictor for Differentiating the Invasiveness of T1 Stage Pulmonary Adenocarcinoma.
The present study was performed to investigate the maximum standardized uptake value (SUVmax) in 2-[fluorine-18]-fluoro-2-deoxy-d-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) to preoperatively distinguish invasive from less-invasive pulmonary adenocarcinoma. ⋯ The present study has demonstrated that the SUVmax is a good preoperative predictor for the invasiveness of pulmonary adenocarcinoma (≤ 3 cm). It will help surgeons plan low invasive treatment of preinvasive tumors.

Multicenter StudyRandomized, Double-Blind Phase Ib/III Study of Erlotinib With Ramucirumab or Placebo in Previously Untreated EGFR-Mutant Metastatic Non-Small-Cell Lung Cancer (RELAY): Phase Ib Results.
Despite the likelihood of an initial response to an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), EGFR-mutant non-small-cell lung cancer (NSCLC) patients develop disease progression. Antiangiogenic agents in combination with an EGFR TKI might provide additional benefit in patients with EGFR-mutant NSCLC. In this article we report safety, exposure, and progression-free survival (PFS) results for part A (phase Ib) of RELAY, a randomized, double-blind, phase Ib/III study investigating safety and efficacy of erlotinib (EGFR TKI) with ramucirumab (anti-vascular endothelial growth factor receptor-2 antibody) or placebo in first-line EGFR-mutant stage IV NSCLC. ⋯ Ramucirumab with erlotinib showed no unexpected toxicities and encouraging clinical activity in part A. Phase III enrollment has been initiated, maintaining ramucirumab 10 mg/kg every 2 weeks with erlotinib 150 mg/d.

Meta AnalysisSafety and Efficacy of PD-1/PD-L1 Inhibitors in Treatment-Naive and Chemotherapy-Refractory Patients With Non-Small-Cell Lung Cancer: A Systematic Review and Meta-Analysis.
Programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors show significant clinical activity in non-small-cell lung carcinoma (NSCLC). However, there is a relative lack of data on comparative efficacy of these drugs in the first-line setting versus chemotherapy-treated patients. We compared the efficacy and toxicity of these drugs in these 2 distinct groups of patients. ⋯ PD-1/PD-L1 inhibitor therapy for advanced NSCLC has a significantly higher ORR and a higher rate of immune-mediated pneumonitis when used in the first-line setting compared with chemotherapy treated patients.
