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.
