Randomized Controlled Trial Multicenter Study
Relationship between nodule count and lung cancer probability in baseline CT lung cancer screening: The NELSON study.
To explore the relationship between nodule count and lung cancer probability in baseline low-dose CT lung cancer screening. ⋯ In baseline lung cancer CT screening, half of participants with lung nodules have more than one nodule. Lung cancer probability does not significantly change with the number of nodules. Baseline nodule count will not help to differentiate between benign and malignant nodules. Each nodule found in lung cancer screening should be assessed separately independent of the presence of other nodules.

Review
Patient-reported outcome measures (PROMs) in the management of lung cancer: A systematic review.
Lung cancer is often associated with a poor quality of life, as reflected by patient-reported outcome measures (PROMs). The aim of this paper is to describe and compare the PROMs that are available. In this manuscript, we review the impact of PROMs on the management of lung cancer. ⋯ The EORTC QLQ-C30 and its lung cancer-specific module QLQ-LC13 are the most frequently used instruments in lung cancer patients. PROMs have the potential to improve the quality of care with a proper implementation in the routine practice. PROMS are needed to value and understand the experience of the patient.

In a phase Ib trial, afatinib plus cetuximab demonstrated promising clinical activity (objective response rate [ORR]: 29%; median progression-free survival [PFS]: 4.7 months) in patients with epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC) with acquired resistance to erlotinib or gefitinib. Here, a separate cohort exploring afatinib plus cetuximab after progression on afatinib is reported. ⋯ NCT01090011.

Review Meta Analysis
PD-L1 expression in advanced NSCLC: Insights into risk stratification and treatment selection from a systematic literature review.
Tumors can evade immune detection by exploiting inhibitory immune checkpoints such as the programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) pathway. Antibodies that block this pathway offer a promising new approach to treatment in advanced/metastatic non-small cell lung cancer (NSCLC). A systematic review of the literature was conducted to assess the association of PD-L1 with important patient and disease characteristics, the prognostic significance of PD-L1 expressing NSCLC tumors, and the value of PD-L1 as a predictive biomarker of response to anti-PD-1/PD-L1 treatments in advanced/metastatic NSCLC. ⋯ Variability in the methods used to determine PD-L1 expression in NSCLC tissue suggests a need for standardized use of well-validated PD-L1 diagnostic assays. Although considerable research links PD-L1 expression in tumors to shorter survival in advanced/metastatic NSCLC, its use as a prognostic factor requires more study. As studies of anti-PD-1/PD-L1 agents continue, PD-L1 is likely to play an important role as a predictive biomarker for selecting patients deriving most benefit from anti-PD-1/PD-L1 monotherapy and directing patients with lower levels of tumor PD-L1 expression (with a high unmet medical need), to alternative treatments, such as combination immunotherapies.

Exploratory analysis of clinical trials in various tumor types have demonstrated potential improvements in overall response rate (ORR) to chemotherapy after exposure to vaccine-based immunotherapy. The objective of this retrospective study was to determine if single-agent chemotherapy (3rd-line or beyond) would yield improved ORR when given after exposure to programmed death-(ligand)1 inhibitors (anti-PD1) in metastatic non-small cell lung cancer (NSCLC). ⋯ In NSCLC patients, the confirmed ORR to single-agent chemotherapy after immunotherapy exposure was higher as compared to historical data from the pre-anti-PD1 era, and approached ORR to first-line platinum-based chemotherapy. Further investigation of a possible immunotherapy-induced chemosensitization effect is warranted.
