e13105 Background: Although poorer outcomes of lung cancer in Blacks compared to other racial groups has been strongly linked to socio-economic factors, it is important to investigate whether lower prevalence of targetable mutations limit treatment options, thereby also contributing to worse outcomes. This study examines the prevalence of EGFR, ALK, ROS-1 and BRAF lung cancer mutations in Blacks compared to other races. Methods: We conducted a meta- analysis compliant with PRISMA guidelines. Searched databases included PubMed/MEDLINE, Cochrane CENTRAL, EMBASE, Google Scholar and clinicaltrials.gov. Publication bias was mitigated by searching clinicaltrials.gov for unpublished studies. Searches were run to 11/19/2018. Two rounds of screening were performed based on title and then abstract by two independent reviewers. For the purposes of this study we defined racial groups as Black, Asian, Hispanic, and White/Caucasian. We selected studies of lung cancer patients (any stage or type) where the prevalence of at least one mutation was reported in Blacks. We calculated the pooled prevalence of mutations by racial group using fixed effects, exact binomial distributions and Freeman-Turkey double arcsine transformation to stabilize the variances. Results: Prevalence % of mutations by race reported with 95% Confidence Interval in parentheses N = number of tests performed We included 20 studies which totaled 11,867 lung cancer patients. Each mutation tested on a tissue sample was considered an event, for a total of 15,306 events. EGFR was the most prevalent mutation in Blacks (6%). Compared to other races Blacks had the lowest prevalence of all four mutations. Conclusions: In the era of targeted therapy, outcomes for metastatic lung have improved significantly. Of concern, our results show that Blacks are disproportionately ineligible for these therapies due to lower prevalence of targetable mutations. More research is needed to evaluate the unique tumor characteristics and therapeutic strategies in this sub group of patients, in the hope of achieving better disease outcomes.[Table: see text]
