This study evaluated patients treated with platinum-based CRT and excluded patients treated with EGFR inhibitors, which are known to result in skin reactions.6 Platinum-based chemotherapy and chemotherapeutic agents of any kind may be associated with some degree of skin toxicity.26 However, it would be difficult to select patients receiving radiation treatment as a monotherapy that also involves the irradiation of the skin. Here, EGFR is linked to dermatological toxicity.
