Correlation between human epidermal growth factor receptor family (EGFR, HER2, HER3, HER4), phosphorylated Akt (P-Akt), and clinical outcomes after radiation therapy in carcinoma of the cervix

These data emphasize that significant correlations exist between the differential expression of various HER family receptors. Multivariate analysis revealed only increased HER2 expression associated with improved OS after controlling for pretreatment clinical factors. These data emphasize the importance of continued basic and translational research on the HER family of receptors in cervical carcinoma.
