Overexpression of EGFR in esophageal squamous cell carcinomas – A new biological target in cancer therapy

Esophageal squamous cell carcinoma (ESCC) is the predominant type of esophageal cancer in the Asian belt. These cancers show poor prognosis with an overall 5-year survival rate less than 19%. Exploring new molecular therapeutic targets such as epidermal growth factor receptor (EGFR) could be the corner stone of new curative treatment. The present study was done to analyze the overexpression of EGFR in different grades of ESCC and explore its role as a diagnostic and theranostic marker in ESCC.
