摘要: Background Previous studies have demonstrated possible differences in glioblastoma (GBM) survival attributable to ethnicity. The goal of this study was quantify oncogenic and evaluate the overall (OS) progression-free (PFS) GBM patients across race/ethnicity using both population-based surveillance institutional data sets from United States (US) Mexico. Methods Retrospective cohort comprising Texas Cancer Registry (TCR, n = 4134) referral institutions located US (n 254) Mexico 47) were evaluated. Primary outcomes include OS PFS. Oncogenic ethnicity assessed. IDH1/IDH2 status evaluated by sequencing samples. Kaplan-Meier Cox proportional hazards regression for analysis. Results A total 4134 identified TCR set, comparison that Hispanic diagnosed at a significantly younger age compared non-Hispanic white (NHW) (median: 58 vs. 62, P Conclusions IDH2 mutations are more prevalent Mexican individuals may be crucial contributor previously reported benefit large population databases. These findings critical screening targeted interventions GBM.
