We conducted a systematic review and meta-analysis to assess the efficacy and safety of ALK inhibitors compared to chemotherapy (ALK vs. chemo) and 2nd generation ALK inhibitors compared to 1st generation ALK inhibitors (ALK 2G vs. ALK 1G).The electronic databases PubMed and EMBASE, were searched for relevant randomized trials. Pooled hazard ratios (HR) for overall survival (OS) and progression free survival (PFS), and pooled risk ratios for objective response rates (ORR) and grade 3 or higher toxicity were meta-analyzed using the generic inverse variance and the Mantel-Haenszel methods. To account for between-studies heterogeneity, random-effect models were used. Subgroup analyses compared PFS by gender, smoking status, brain metastases, race and age.This meta-analysis is the first, to our knowledge, to report an OS improvement with the use of ALK vs. chemo. A trend toward a better OS was also seen with ALK 2G vs. ALK 1G and this is likely because of crossover effects and limited OS f..... READ ARTICLE
