More on treatment de-escalation, biomarkers of response in human epidermal growth factor receptor 2 (HER2)-positive breast cancer: long-term outcomes and translational research findings the PREDIX HER2 trial

Epidermal growth factor, a potent mitogen, stimulates phosphorylation of its 170,000-dalton plasma membrane receptor. Dimethyl sulfoxide selectively increased phosphorylation of the epidermal growth factor receptor in rat liver microsomal fraction. Maximal stimulation occurred at 15 to 25 percent dimethyl sulfoxide and resembled the effect of epidermal growth factor in magnitude and rapidity. L...

BACKGROUND AND PURPOSE Epidermal growth factor receptor amplification is a common molecular event in glioblastomas. The purpose of this study was to examine the potential usefulness of morphologic and diffusion MR imaging signs in the prediction of epidermal growth factor receptor gene amplification status in patients with glioblastoma. MATERIALS AND METHODS We analyzed pretreatment MR imagin...

PURPOSE Prostate cancer cell motility and invasion have been linked to the up-regulated signaling of epidermal growth factor receptor and urokinase-type plasminogen activator receptor. We analyzed the expression of serum urokinase-type plasminogen activator receptor and epidermal growth factor receptor in the serum of patients with clinical suspicion of prostate cancer to evaluate the possible ...

Epidermal growth factor receptors are present in some breast cancers in man, and there is an inverse relation to oestrogen receptor state. We assessed the presence of epidermal growth factor receptors as a single prognostic indicator in a series of breast tumours by comparing this with the Bloom and Richardson scores for these tumours. One hundred and eight ductal tumours were examined for epid...
