title: The prognostic value of epidermal growth factor receptor (EGFR) in breast cancer patients. Results of a follow-up study on 149 patients.
abstract: The expression of epidermal growth factor receptor (EGFR) in breast cancer patients was correlated to the disease-free survival. The study included 149 breast cancer patients. The mean follow-up time was 4.2 years. There was an inverse correlation between EGFR and estrogen receptor (p < 0.003) and progesterone receptor (p < 0.013). Subdivision of EGFR showed that patients with EGFR > or = 0.60%, regarded as EGFR positive, had a worse prognosis than patients with EGFR binding < 0.60%, regarded as EGFR negative (p = 0.004). In the ER negative group, EGFR positive patients had a shorter relapse-free time than patients with EGFR negative cancer (p < 0.009). The same subdivision among ER positive patients showed no statistically significant difference.
