Rash management and treatment persistence of cancer patients treated with epidermal growth factor receptor inhibitors in the Truven MarketScan ® research database

Purpose Rash toxicity is a common, expected class effect of epidermal growth factor receptor (EGFR) inhibitors. Although rash management is practiced, it is not well characterized in the real-world setting. We describe the management of rash that developed while receiving EGFR-inhibitor therapy and how rash affects treatment duration, using Truven MarketScan® Research Database, a US medical claims database.
