Abstract

Transforming growth factor alpha (TGFa) and Transforming growth factor beta-I (TGF-P,) are growth regulatory for breast cancer cell lines in vitro and several studies have suggested that levels of the receptor for TGFa, the epidermal growth factor (EGFR) in tumour biopsies predict relapse and survival. We have examined the prognostic significance of TGFax, TGF-P, and EGFR mRNA expression in a series of patients with primary breast cancer with a median follow up period of 60 months. In 167 patients the expression of TGF-P, was inversely correlated with node status (P = 0.065) but not ER status, tumour size or menopausal status. Patients with high levels of TGF-P, had a longer disease free interval with a significantly longer probability of survival at 80 months although the overall relapse free survival was not increased. EGFR mRNA expression was measured in 106 patients and was inversely correlated with ER status (P = 0.018). EGFR levels did not predict for early relapse or survival. TGFa mRNA levels were measured in 104 patients, no correlation was seen tumour size, node status, Er status, or clinical outcome.
