Epidermal growth factor receptor inhibitors (EGFRI) belong to the so called targeted cancer therapy and are used for the treatment of different cancer types like non-small-lung-cancer (NSLC), head-and-neck-cancer (head-and-neck-ca), colon-rectal-cancer (colon-ca) and pancreas-cancer (pancreatic -ca) [1–4]. Here, EGFR is linked to cancer.
