Abstract

Objective To study the expression of epidermal growth factor receptor (EGFR) in cervical car-cinoma and cervical intraepithelial neoplasia(CIN),and to elucidate its relation with the genesis, infiltration, metas-tasis and prognosis of cervical carcinoma. Methods EGFR was determined by means of S-P immunohistochemistry in tissue of 100 cases of cervical carcinoma,60 cases of CIN and 40 cases of controls. Results The overexpression rates of EGFR were 0% (0/40), 51.67% (31/60),78.00% (78/100), respectively in normal cervical epithelium, CIN and cervical tumor tissues. The overexpression rate of EGFR was significantly higher in cervical tumor tissue than in control group(P 0.05). Conclusion Overexpression of EGFR is worsened with the severity of cervical lesion, suggesting that overexpression of EGFR is correlated with the genesis of cervical neo-plasms,which may be a valuable biological indicator of cervical carcinoma,but is not correlated with clinical patho-logical features and prognosis of cervical carcinoma. Key words: Cervical carcinoma; Cervical intracpithelial neoplasia; Epidermal growth factor receptor; Immunohistochemistry
