[Management of cutaneous toxicities induced by epidermal growth factor receptor inhibitors: a review]

Abstract

The epidermal growth factor receptor (EGFR) is overexpressed in many solid tumors. Its inactivation has an inhibitory effect on the growth and spread of the tumoral cells. It therefore represents an attractive target to treat different cancers. Several molecules have already been registered while others are still under evaluation. One of the common side effects of these therapies is the development of cutaneous toxicities, more precisely a cutaneous rash, sometimes major and distressing. The physiopathology of these cutaneous side effects is poorly understood. Moreover a correlation between the severity of the rash and the tumoral response has been demonstrated in some studies. If this link is confirmed, the rash could be used as a marker for the anti-tumoral activity. This review will summarize the clinical presentations and the current recommendations for the management of cutaneous toxicities induced by EGFR inhibitors.
