Significantly, we posit that
use of EGFR-TKIs as a priming approach to stimulate innate immunity is relevant to patients with
wild-type disease. However, its potential efficacy may not be apparent in the setting of daily continuous
therapy due to suppression of innate and adaptive immunity by prolonged use of EGFR-TKIs. As a
therapy, EGFR-TKIs could augment responses to PDT and XRT through multiple mechanisms that
