EGFR and breast cancer: In our analysis, we found a direct correlation between FAM83A and EGFR protein levels stronger in normal (r = 0.4, p < 0.0001) than in BC (r = 0.2, p < 0.0001) samples suggesting that FAM83A may be involved in the EGFR-driven proliferative pathway in the normal breast and early phase of BC development rather than only in advanced BC as previously described [6].
