Mining the TIMER database for associations between gene alteration and immune cell infiltrate illustrates that EGFR mutation or amplification in GBM patient samples does not correlate with any change in T-cell infiltration (Figure 5C), in contrast to lung adenocarcinoma, where EGFR alteration is associated with reduced T-cell infiltration (Figure 5D). Here, EGFR is linked to lung adenocarcinoma.
