Abstract:
Objective To study the expression of HPV、p16 and Her-2 in the squamous cell cervical carcinoma and its chnical significance. Methods Expression of HPV16/18、p16, and C-erbB-2 and the amplification of Her-2 gene were examined using situ hybridization technique,SP immunohistochemistry,and FISH imaging analysis system in 60 cases of cervical cancer, 61 cases of CIN, and 21 cases of normal cervical tissue,respectively.Results The positive rates of HPV16/18 and p16 in the normal tissue,CIN Ⅰ -Ⅱ,CINⅢ and the squamous cell cervical carcinoma were gradually increased, they wereo (0/21),9.68 ％ (3/31),46.67 ％ (14/30),71.67 ％ (43/60);0 (0/21),19.35 ％ (6/31),93.33 ％ (28/30),96.67 ％ (58/60),respectively,and there were significant differences among the groups (P＜0.05),but no significant difference was found between the normal tissue and the CIN Ⅰ - Ⅱ. The positive rates of Her-2 and Her-2 in the CIN Ⅲ and the carcinoma were 13.33 ％ (4/30),31.67 ％ (19/60),3.33 ％ (1/30),21.67 ％ (13/60),respectively,but in the normal group and the CIN Ⅰ - Ⅱ wereo,and the differences between the carcinoma group and the CIN group,the carcinoma group and the normal group were significant(P＜0.05).The expression of Her-2 and the amplification of Her-2 were closely related to the stage, degree of differentiation and metastasis of lymph node in the squamous cell cervical carcinoma (P＜0.05). Conclusion The infection of HPV is one of thetriggers for the squamous cell cervical carcinoma.The expression of p16 and the amplification of Her-2 may be closely correlated with tumor development and high expression of p16 and Her-2 indicates poor prognosis.
