International audience. Targeting EGFR and HER3 with a specific dual antibody (MEHD7945A) enhanced irradiation efficacy in vitro (cervical cancer cell lines) and in vivo (xenografted mice) in an additive way. Moreover, our study suggests that co-expression of EGFR and HER3 could be a candidate prognostic biomarker of poor overall survival in patients with cervical cancer. These preliminary results should be confirmed in a study with a larger sample.
