Review Meta Analysis
Smoking cessation interventions within the context of Low-Dose Computed Tomography lung cancer screening: A systematic review.
The integration of smoking cessation interventions (SCIs) within the context of lung cancer screening programs is strongly recommended by screening guidelines, and is a requirement for Medicare coverage of screening in the US. In Europe, there are no lung cancer screening guidelines, however, research trials are ongoing, and prominent professional societies have begun to recommend lung cancer screening. Little is known about the types and efficacy of SCIs among patients receiving low-dose computed tomography (LDCT) screening. ⋯ Findings from this review suggest that participation in a lung screening trial promotes smoking cessation and may represent a teachable moment to quit smoking. Findings also suggest that providers can take advantage of this potentially teachable moment, and that SCIs have been successfully implemented in screening settings. Continued systematic and methodologically sound research in this area will help improve the knowledge base and implementation of interventions for this population of smokers at risk for chronic disease.

Meta Analysis
Pooled safety analysis of EGFR-TKI treatment for EGFR mutation-positive non-small cell lung cancer.
Three epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) - afatinib, erlotinib, and gefitinib - are available for the treatment of patients with EGFR mutation-positive non-small cell lung cancer (NSCLC). Given the long-term exposure of such patients to EGFR-TKIs, the toxicological properties of these agents in these individuals may differ from those observed in unselected patients. We compared the frequencies of severe adverse events (AEs) among EGFR mutation-positive NSCLC patients treated with these three EGFR-TKIs. ⋯ Such information on AEs should facilitate selection of the most appropriate EGFR-TKI for EGFR mutation-positive NSCLC patients with regard to mitigation of the risk for certain types of toxicity.

Review Meta Analysis
Afatinib in the treatment of EGFR mutation-positive NSCLC--a network meta-analysis.
Epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC) is a specific lung cancer subtype characterized by sensitivity to treatment with EGFR tyrosine kinase inhibitors (TKIs). Two reversible EGFR TKIs (gefitinib, erlotinib) and the irreversible ErbB family blocker afatinib are currently approved for treatment of EGFR mutation-positive NSCLC, but no head-to-head trials have been reported to date. We aimed to assess the relative efficacy of the three drugs by conducting a network meta-analysis (NMA). ⋯ In the absence of direct head-to-head trial data comparing efficacy between the three EGFR TKIs, our analysis suggests that afatinib is a viable treatment alternative to erlotinib or gefitinib in terms of PFS. A direct trial-based comparison of the efficacy of these agents is warranted to clarify their relative benefits.

Meta Analysis Comparative Study
Efficacy of epidermal growth factor receptor inhibitors versus chemotherapy as second-line treatment in advanced non-small-cell lung cancer with wild-type EGFR: a meta-analysis of randomized controlled clinical trials.
EGFR mutation status is closely related to the efficacy of EGFR-TKIs in advanced non-small cell lung cancer (NSCLC). EGFR-TKIs have become the standard first-line treatment for advanced EGFR-mutation NSCLC, while for EGFR wild-type tumors, the preferred first-line treatment is chemotherapy. However, the efficacy of EGFR-TKIs as second-line treatment in EGFR wild-type NSCLC remains controversial. We sought to evaluate the effectiveness of EGFR-TKI as second-line treatment in EGFR wild-type NSCLC. ⋯ Chemotherapy improves PFS significantly but not OS, compared with EGFR-TKIs as a second-line treatment in advanced NSCLC with wild-type EGFR. Whether EGFR-TKIs should be used in EGFR wild-type patients should be considered carefully.

Review Meta Analysis
Risk of interstitial lung disease with gefitinib and erlotinib in advanced non-small cell lung cancer: a systematic review and meta-analysis of clinical trials.
Gefitinib and erlotinib are oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) widely used in advanced non-small cell lung cancer (NSCLC). Interstitial lung disease (ILD) events have been described with these agents, although the overall risk remains unclear. We performed a systematic review and meta-analysis to determine the incidence and the relative risk (RR) associated with the use of gefitinib and erlotinib. ⋯ Treatment with EGFR TKIs gefitinib and erlotinib is associated with a significant increase in the risk of developing both all-grade and fatal ILD events in advanced NSCLC.
