In this chapter we consider the relationships that involve both HER-2 and epidermal growth factor receptor (EGFR), with a particular focus on the potential use of these two transmembrane growth factor receptors as biomarkers for predicting response to targeted therapeutic agents directed at either or both of them. Effective clinical use of these receptors as biomarkers depends both on an understanding of their complex biological interactions, and an awareness of the shortcomings of current methods of measuring these two cellular constituents in the clinical setting. Here we will review selected aspects of these two topics, and attempt to develop working hypotheses and organizing principles that might be useful in translating basic knowledge into clinical practice.
