Abstract:
Objective To investigate the human papillomavirus 16/18 (HPV16/18) infective status and its relationship with the expression of p16,CK17,Ki-67 in immature squamous metaplasia(IM),cervical intraepithelial neoplasia (CIN) and cervical carcinomas (CC).Methods In situ hybridization (ISH) and immunohistochemistry were applied to detect the expression of HPV16/18,p16,CK17,Ki-67 on tissues from 30 IM,60 CIN and 30 CC.Results The expression rates of HPV16/18 in LSIL,HSIL and CC were 30 ％ (9/30),60 ％ (18/30) and 77 ％ (23/30),higher than that in IM [6.7 ％ (2/30)].HPV16/18 was positively expressed with the progression of cervical squamous epithelial lesions.The expression rates of CK17 in IM was 90 ％ (27/30),higher than that in LSIL,HSIL and CC [17 ％ (5/30),10 ％ (3/30),6.7 ％ (2/30)].The expression rates of p16,Ki-67 were 83 ％ (25/30) and 87 ％ (26/30) in LSIL,90 ％ (27/30) and 93 ％ (29/30) in HSIL,97 ％ (29/30) and 97 ％ (29/30) in CC,higher than that in IM [13 ％ (4/30) and 10 ％ (3/30)].The expression of p16,Ki-67 were particularly seen in HPV16/18-positive HSIL and CC,and the correlation were observed.Conclusion HPV16/18 infection is highly associated with the degree of squamous intraepithelial neoplasia and carcinomas of cervix and upregulated p16 and Ki-67,which suggested that HPV16/18 maybe cause mutation of p16 gene.With the progression of cervical squamous epithelial lesions,positive expression rates of CK17 were decreased compared with increased of HPV16/18,p16,Ki-67.Combined detection of HPV16/18,p16,Ki-67 is helpful for diagnosis and classification of cervical squamous epithelial lesions.
