Summary The prognostic value of epidermal growth factor receptor (EGF-R) was prospectively assessed in a series of 229 clinical T1-T2, N0-N1 breast carcinomas diagnosed between May 1987 and October 1989. EGF-R expression was determined by measuring the specific Bmax of125I EGF to tumor plasma membrane preparations. Tumor with a B max ≥ 3 fmol/mg of protein were considered positive with regard to EGF-R expression. With a median follow-up of 34 months, the 3-year overall and disease-free survivals are respectively 92% and 88% for EGF-R ≤ 3, and 91% and 86% EGF-R 〉 3 fmol, showing no significant difference, even when comparing axillary lymph node status. We did not succeed in finding an EGF-R cut-off value which might be significant in univariate analysis. Multivariate analysis of our data indicates that pT (p = 0.001), pN (p = 0.04), and Scarff-Bloom grade (p = 0.04) are the only significant predictors of disease-free survival among the parameters investigated in this study.
