MANAGEMENT OF SKIN RASH DURING EGFR-TARGETED MONOCLONAL ANTIBODY TREATMENT FOR GASTRO INTESTINAL MALIGNANCIES: CANADIAN RECOMMENDATIONS
AbstractThe epidermal growth factor receptor (EGFR) is often overexpressed or dysregulated in a variety of solid tumours, including gastrointestinal (GI) malignancies. Agents targeting the EGFR-mediated signaling pathway are increasingly part of the therapeutic armamentarium for the treatment of advanced lung, head and neck, and colorectal carcinoma. EGFR inhibitors (EGFRIs) approved in Canada include the tyrosine kinase inhibitors (TKIs) erlotinib and gefitinib (in selected cases), as well as the monoclonal antibodies (mAbs) panitumumab and cetuximab. While EGFRIs have been proven effective in the treatment of a variety of malignancies, the entire class of agents is associated with a high prevalence of dermatological side effects, most commonly skin rash. This reversible condition requires intervention in approximately one-third of patients. A proactive, multidisciplinary approach to management can help to improve skin rash and optimize clinical outcomes by preventing EGFRI dose reduction or discontinuation. In addition, effective management and patient education may help to alleviate the significant social and emotional anxiety related to this manageable side effect, thus resulting in improved quality of life. This article will focus on EGFR-targeted mAbs for the treatment of GI malignancy, addressing the pathophysiology, clinical presentation and incidence of skin rash caused by this class of agents. Recommendations aimed at establishing a framework for consistent, proactive management of skin rash in the Canadian setting will be presented.
