Overview

Cetuximab + radiotherapy refers to the concurrent use of the monoclonal antibody **cetuximab** in combination with **radiotherapy**. Cetuximab is an epidermal growth factor receptor (EGFR) inhibitor that blocks ligand-induced phosphorylation of EGFR, thereby inhibiting downstream signaling pathways critical for cell proliferation and survival. When combined with radiotherapy, cetuximab acts as a radiosensitizer—enhancing the cytotoxic effect of radiation on tumor cells. This combination has demonstrated benefit in the treatment of locally or regionally advanced squamous cell carcinoma of the head and neck and has also been investigated in non-small cell lung cancer (NSCLC), particularly in patients who are not candidates for chemoradiation[1][2][3][4].
