EGFR and cancer: Similarly, we found that, as compared to the other type of 7702 tumor tissues, the overall EGFR expression in 513 thyroid cancers is significantly overexpressed with 1.35-folds (thyroid cancers versus other cancers = 9.535 ± 0.049 versus 9.1838 ± 0.037 fluorescence intensity-log2, P = 0.001).
