The epidermal growth factor receptor (EGFR) is now recognized as an important target for therapeutic interventions in many types of cancer. Because of the prognostic significance of EGFR expression in cancer and the laboratory data that provide direct evidence for aberrant EGFR signaling in cancer cells, this growth factor receptor is being targeted clinically with the use of both antibody- and small molecule-based approaches (1). In this issue of the Journal, Lammering et al. (2) extend their previous observations on the usefulness of targeting the EGFR to improve the therapeutic efficacy of ionizing radiation. Previously, these investigators demonstrated that exposure of EGFR-positive human breast cancer cells to therapeutically relevant
