Comparison of Skin Toxic Effects Associated With Gefitinib, Erlotinib, or Afatinib Treatment for Non–Small Cell Lung Cancer

With Gefitinib, Erlotinib, or Afatinib Treatment for Non-Small Cell Lung Cancer Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have been widely used to treat non-small cell lung cancer. Four major skin toxic effects with different incidences have been reported from clinical studies, including acneiform eruption (60%-94%), pruritus (16%-60%), xerosis (4%-38%), and paronychia (6%-12%). 1,2 However, a direct comparison of the incidences and severities of the 4 types of skin toxic effects for 3 different EGFR-TKIs in the same patient cohort has been lacking to date.
