The importance of immunohistochemical expression of EGFr in squamous cell carcinoma of the oral cavity treated with surgery and postoperative radiotherapy

Conclusions: In the present study, no association was found between EGFr expression and outcome regarding locoregional control and overall survival. However, the results of the present study suggest that patients with squamous cell carcinoma of the oral cavity with high EGFr expression benefit more from a reduction of the overall treatment time of postoperative radiation than those with low EGFr expression.
