We also used two independent GBM patient cohorts to validate our results, and although the OS and PFS analysis did not show statistically significant association with the TSPO SNP, we observed that the rs6971 wild-type A/A genotype carriers have a better survival time only in GBM male patients as compared with the carriers of at least one G allele, showing a similar trend to the CCF cohort. Here, TSPO is linked to glioblastoma.
