EGFR and neoplasm: Furthermore, lymphocytic infiltrates across all 20 epithelial cancers expressed CD27 mRNA, demonstrating a clear correlation between lymphocyte infiltration score and CD27 (R2 = 0.6895) within the whole epithelial cancer set, confirming that the strategy of EGFR-mediated crosslinking of CD27 could be employed within epithelial cancers (Figure 1B, see Supplementary Figure 2 for individual tumor types).
