EGFR is generally considered to be a negative prognostic factor in breast cancer (Pawlowski et al, 2000; Tsutsui et al, 2002; Witton et al, 2003; Tzaida et al, 2007), but up to now, no definitive association between EGFR expression and survival has been demonstrated. This evidence concerns the gene EGFR and breast carcinoma.
