RESUMEN
Objective: To study the level of squamous cell antigen (SCC?Ag) and cyclin E in cervical intraepithelial neoplasia ( CIN) and cervical cancer, and to explore the clinical significance. Methods: From Nov 2012 to Nov 2015, 308 patients with CIN or cervical cancer were chosen as research objects, and 170 patients with uterine leiomyoma or uterine gland muscle disease for hyster?ectomy and after pathological examination of the normalcases were chosen as control group. The SCC?Ag level, positive expression rate in blood, and positive expression of Cyclin E in cervical tissue for patients with different cervical lesions were compared. Results: The SCC?Aglevel , positive expression rate in blood, and positive expression of Cyclin E in cervical tissue for patients with cervical canc?er, CIN were higher that those in the control group ( P<0?05) . The SCC?Aglevel, positive expression rate in blood, and positive ex?pression of Cyclin E in different CIN grades and different stages of cervical cancer patient had significant difference ( P<0?05) . Con?clusion: Blood SCC?Ag level and positive expression, Cyclin E positive expression in the cervical tissue have a close relationship with occurrence and development of CIN and cervical cancer .
