Management of epidermal growth factor receptor inhibitor-associated rash: a systematic review

Cancer patients treated with epidermal growth factor receptor inhibitors (EGFRIs) frequently experience skin toxicities (rash) that can compromise their quality of life and lead to dose reduction or discontinuation of treatment. Reflecting the need for effective management of EGFRI-associated rash, a number of clinical practice guidelines and management recommendations have been developed. The objective of this systematic review is to identify and summarize all available published recommendations of rash management strategies and evaluate their basis of evidence, to describe consensus in the recommendations, and where there is a lack of consensus to describe the opportunities for future clinical research to improve clinical practice in the management of EGFRI rash. Fifty-nine articles published from 2005-2011 were selected for inclusion in the systematic review. Common drug recommendations were oral and topical antibiotics, topical corticosteroids, and antihistamines; low-grade rash was generally recommended to be managed with topical antibiotics or corticosteroids, grade 2 rash with oral antibiotics or antihistamines, and severe grades of rash with oral corticosteroids or delay/dose reduction of EGFRI. The focus of clinical practice guidelines and recommendations was on reactive management. A better understanding of pre-emptive versus reactive treatment with the implementation of appropriately designed randomized controlled studies could support a more effective management of EGFRI-associated rash and improve patient outcomes. Consideration of patients' self-reported outcomes and consistent grading of rash toxicity are also recommended. Funding/sponsor: Eli Lilly & Co, Bristol-Myers Squibb.
