摘 要:目的探讨HPV16/18感染及p16、CK17、Ki-67在子宫颈不成熟鳞状化生(IM)、子宫颈上皮内瘤变(CIN)及子宫颈鳞状细胞癌(CC)中的表达及关系。方法应用原位杂交及免疫组织化学法检测HPV16/18、p16、CK17、Ki-67在子宫颈IM 30例、CIN 60例[低级别上皮内病变(LSIL)30例,高级别上皮内病变(HSIL)30例]、CC 30例标本中的表达情况,并对结果进行对比分析。结果HPV16/18感染在LSIL、HSIL及CC中的阳性率[30 %(9/30)、60 %(18/30)、77 %(23/30)]高于IM组[6.7 %(2/30)],差异均有统计学意义(均P〈0.05),并且随着子宫颈病变加重,HPV16/18的表达率也呈递增趋势。CK17在IM中的阳性表达率[90 %(27/30)]高于LSIL、HSIL及CC组[分别为17 %(5/30)、10 %(3/30)、7 %(2/30),P〈0.05]。p16、Ki-67在LSIL中的表达率分别为83 %(25/30)、87 %(26/30),HSIL中为90 %(27/30)、93 %(28/30),CC中为97 %(29/30)、97 %(29/30),均高于IM组[13 %(4/30)、10 %(3/30)]。HPV16/18阳性的HSIL及CC中均发现p16、Ki-67的高表达,三个指标之间均具有相关性。结论高危型HPV16/18感染与CIN及子宫颈癌的发生密切相关,且常伴随p16、Ki-67的高表达,提示HPV16/18可能引起抑癌基因p16突变,导致细胞癌变。随着子宫颈鳞状上皮病变加重,CK17阳性率明显降低,HPV16/18、p16、Ki-67的阳性率明显增高,联合检测对子宫颈鳞状上皮病变的诊断及分级具有辅助意义。ObjectiveTo 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). MethodsIn 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. ResultsThe 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. ConclusionHPV16/18 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.
