Meta Analysis Comparative Study
Is There a Survival Benefit of First-Line Epidermal Growth Factor Receptor Tyrosine-Kinase Inhibitor Monotherapy Versus Chemotherapy in Patients with Advanced Non-Small-Cell Lung Cancer?: A Meta-Analysis.
Tyrosine-kinase inhibitors (TKIs) markedly improve progression-free survival (PFS) of patients with advanced non-small-cell lung cancer (NSCLC) mutated for epidermal growth factor receptor (EGFR). Results on overall survival (OS) are less clear-cut. We performed a publication-based meta-analysis to address further this issue. ⋯ The major discrepancy between a similar OS and a markedly improved PFS after first-line TKI compared with chemotherapy could be related to the high level of crossing-over between both groups.

The Efficacy of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors for Molecularly Selected Patients with Non-Small Cell Lung Cancer: A Meta-Analysis of 30 Randomized Controlled Trials.
To determine the efficacy of first-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in molecularly selected patients with advanced non-small cell lung cancer (NSCLC), we performed this pooled analysis. ⋯ For EGFR mutant patients, EGFR-TKIs therapy produced a prominent PFS benefit in all settings. Among EGFR wild-type patients, EGFR-TKIs were inferior to chemotherapy both for first-line treatment and for second/third-line treatment. However, EGFR-TKIs maintenance and addition of EGFR-TKIs to chemotherapy could provide additive benefit over chemotherapy alone in such EGFR wild-type patients.
