Abstract:
Objective To explore the relationship between HPV infection ,the expression of PCNA ,Ki-67,p53 in cervical carcinoma and clinicopathologic data .Methods Seventy-six cases of cervical cancer tissues with complete clinical data were collected from the third affiliated hospital of harbin medical university from march 2012 to September 2012 .Tissue microarray technology ,immunohistochemical technique and statistic method were adopted to make comparative analysis among HPV ,PCNA,Ki-67,and p53 expression in patrents with cervical cancer.Results The expression rate of HPV in cervical carcinoma was 68.4%,which was related to the lym-phatic metastasis(P<0.05).Expression of PCNA in cervical cancer tissue was 90.1%and 100%in female pa-tionts women under the age of 35.The expression rate of Ki -67 and p53 were 48.9%and 38.2%respectively, both were correlated to lymphatic metastasis(P<0.05)and preoperative chemotherapy(P<0.01).Conclusion HPV infection with Ki -67,and p53 expression in cervicalcancer tissues are associated with the presence of lymph node metastasis .HPV promotes cervical epithelial cell proliferation ,inactivates tumor suppressor gene p 53 function ,and promotes the invasion and metastasis of cervical cancer .Preoperative chemotherapy of cervical canc-er can reduce the expression of p53,PCNA and Ki-67.
