摘要: 目的:探讨宫颈脱落细胞中hTERC的基因表达在宫颈上皮内瘤样病变(CIN)诊断与治疗中的应用。方法:抽取行子宫颈癌筛查的724例妇女为研究对象,对其同步进行宫颈脱落细胞的液基细胞学检查、第二代杂交捕获技术(HC-Ⅱ)检测高危型HPV(HR-HPV)和荧光原位杂交(FISH)技术检测hTERC基因。对于细胞学为未明确诊断意义的不典型鳞状上皮细胞(ASCUS)及以上病变,和(或)HR-HPV阳性者均行阴道镜下宫颈四象限多点活检进行病理诊断。结果:724例中经病理确定为CINⅠ,Ⅱ,Ⅲ及子宫颈癌者分别为251例(34.67%)、17例(2.35%)、48例(6.63%)和10例(1.38%),宫颈脱落细胞hTERC的扩增率为11.05%。①724例HPV阳性率为39.64%;hTERC扩增在HPV阳性与阴性组分别为19.86%与5.26%(χ2=37.556,P <0.01)。②hTERC扩增在细胞学无宫颈上皮内瘤变(NILM)组为5.19%、ASCUS为10.23%、低度鳞状上皮内瘤样病变为(LSIL)11.84%、非典型鳞状上皮细胞-不除外高度鳞状上皮内瘤变(ASC-H)为21.43%、高度鳞状上皮内瘤样病变(HSIL)为73.17%、鳞状细胞癌(SCCA)为100.00%、非典型腺上皮细胞(AGC)为50.00%;hTERC在HSIL及以上病变中的扩增率明显高于LSIL及以下病变(χ2=186.755,P <0.01)。③在不同组织学结果中hTERC的扩增率分别为,NILM 3.70%、CINⅠ4.38%、CINⅡ47.06%、CINⅢ58.33%、浸润癌90.00%,hTERC在CINⅡ及以上级别病变中的扩增率明显高于CINⅠ和NILM者 (χ2=144.597,P <0.01)。结论:hTERC的扩增与宫颈细胞学和组织学异常密切相关,hTERC扩增与否有可能作为判断有无高度病变及估计预后的指标之一。

Abstract: Objective:To investigate the amplification of hTERC gene in the cervical exfoliated cells,explore its value in diagnosis and treatment of cervical intraepithelial neoplasia(CIN). Methods:724 women were examined with liquid-based cytology, high-risk human papillomavirus(HR-HPV) testing using hybrid capture Ⅱ(HC-Ⅱ) and hTERC gene detection using fluorescence in situ hybridization(FISH) in Peking University Shenzhen Hospital. The patients with ASCUS and above lesion and/or positive HR-HPV results were examined by colposcopy,multiple biopsies of cervical quadrant and pathology. Results:The frequency of CIN Ⅰ,Ⅱ,Ⅲ,cervical cancer were 251(34.67%),17(2.35%),48(6.63%)and 10(1.38%) respectively in 724 patients, the rates of hTERC gene amplification was 11.05%. There was significant difference of hTERC amplification among the samples with different cytological and histological lesions and the HPV infection(P <0.01). ①The positive rate of HPV infection in 724 patients was 39.64%;The positive rates of hTERC gene amplification were 19.86% in HPV positive and 5.26% in HPV negative (χ2=37.556,P <0.01). ②In cytology,the rates of hTERC gene amplification were NILM(5.19%),ASCUS (10.23%),LSIL(11.84%),ASC-H(21.43%),HSIL (73.17%), SCCA (100.00%),AGC(50.00%);There was a marked increase of hTERC amplification in patients with HSIL and above lesion (χ2=186.755,P <0.01). ③In histology,the rates of hTERC gene amplification were respectively normal(3.70%),CINⅠ(4.38%),CINⅡ(47.06%),CINⅢ(58.33%),invasive carcinoma(90.00%). There was a marked increase of hTERC amplification in patients with CINⅡand above lesion(χ2=144.597,P <0.01). Conclusion:There was a tight correlation between amplification of hTERC and the histological and cytological lesion. hTERC amplified or not may be as a prognostic indicator to judge whether high grade lesion or not.
