The results in GBM patients showed that an increased expression of GZMB (HR = 1.5, logrank p = 0.035), SDC1 (HR = 1.6, logrank p = 0.01) and MGMT (HR = 1.7, logrank p = 0.0033) predicted a poor OS, while the results for CD3D, CD3E, CD3G, CD4, CD8A, CD8B, MS4A1, PD-L1, ALOX5 and TGM2 were not statistically significant. Here, CD8B is linked to glioblastoma.
