Principle of Treatment Escalation

At the time of the creation of this website (2009), there were no evidence-based guidelines for the management of dermatological toxicities associated with EGFRI treatment. Treatment algorithms described on this website are, therefore, compiled from a review of the literature or based on reported expert guidance and anecdotal or small-series case reports.

[Update: In 2011, the MASCC published a Clinical practice guidelines for the prevention and treatment of EGFR inhibitor-associated dermatologic toxicities.]

Treatment decision-making requires careful diagnosis of the particular clinical situation. The information provided on this website may serve as one tool among others to help you in treatment decision-making.
