人乳头瘤病毒基因亚型分布及与宫颈病变关系分析

目的:探讨女性HPV感染率和基因亚型分布,分析其与宫颈病变的关系.方法:收集四川大学华西第二医院2011年9月至2012年8月妇科就诊29832例女性患者的宫颈脱落细胞进行HPV基因分型检测.对2398例同时具有宫颈活检组织病理诊断结果的患者进行分组,包括慢性宫颈炎症组599例;CIN Ⅰ组437例;CINⅡ/Ⅲ组906例(CINⅡ338例,CINⅢ568例);宫颈癌组456例.结果:HPV感染率为25.20％(7518/29832),其中高危型HPV、低危型HPV、HPV多重感染率分别为21.03％(6275/29832)、4.17％(1243/29832)、5.94％(1772/29832).常见的高危型HPV为HPV16、58、33、52、18.随着年龄增加,HPV感染率呈现增高趋势.随着宫颈病变的严重程度增加,HPV感染率增高.所有宫颈病变中,常见的高危型HPV由高至低依次为HPV16、58、33、18、52;在宫颈癌组中为HPV16、18、58、33、52;在CINⅡ/Ⅲ组为16、58、33、52、18.在HPV阳性的不同程度宫颈病变中均以单一感染为主,除慢性宫颈炎组外,单一感染的比例随宫颈病变程度增加而增加.结论:本研究最常见的高危型HPV为16、58、33、52、18,与其他地区相比存在一定的地区差异.HPV感染率随年龄增加呈现增高趋势.在不同宫颈病变中,HPV的型别分布有所不同,单一感染可能更易导致宫颈癌的发生.     

高危型人乳头瘤病毒HPV16、18检测在宫颈病变诊断中的应用

宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)是一组与浸润性宫颈癌密切相关的病变。人乳头瘤病毒(human papillomavirus,HPV)是宫颈癌的首要致病原因,高危型HPV阳性增加了CINⅡ、Ⅲ级和宫颈浸润癌的危险性,持续高危型HPV感染是CIN进展的必要条件。因此,HPV检测及分型,对预测病变转归、治疗方案的选择等有重要意义。本文对高危型HPV检测在宫颈病变诊断中的应用进行了探讨。1资料与方法1.1标本来源及诊断标准病例来源于北京大学第三医院妇科门诊就诊患者。从2003年1月至2004年3月,选择了超薄液基细胞学(thin-prep cyto…     

多重人乳头瘤病毒感染检测在宫颈病变诊断中的价值

目的探讨人乳头瘤病毒（human papillomavirus,HPV）检测在宫颈病变筛查中的意义,以及多型别HPV感染与宫颈病变的关系。方法2005年8月至2006年10月应用HPV基因分型技术对北京市垂杨柳医院967例门诊患者进行检测,阳性者进行细胞学检测,两者均阳性者行阴道镜检测;并与同期门诊行细胞学检测的512例患者对比。结果967例中筛查出360例HPV感染患者,感染率为37.23%,单一型别感染率为61.11%,多型别感染率为38.89%。在多型别感染中2种型别感染比例最多（57.86%）。从正常组织到宫颈上皮内瘤样病变（CIN）Ⅱ的不同病变中,多重感染的比例随病变级别上升逐渐增加,与正常者相比差异有显著性意义（P〈0.05）。在CINⅢ和宫颈癌中,多重感染的比例有所下降,但明显高于正常者。HPV联合宫颈薄层液基细胞学（TCT）检测与单纯TCT检测比较,两者中低度鳞状上皮内病变（LSIL）分别为13.33%和5.27%,高度鳞状上皮内病变（HSIL）为4.17%和0.78%,癌为0.56%和0.20%,两者比较差异有显著性意义,P〈0.01。结论结合HPV检测可提高TCT检测的敏感性,多重HPV感染及型别与宫颈病变级别相关。     

人乳头瘤病毒基因亚型与宫颈病变的关系

宫颈癌是女性生殖系统常见的恶性肿瘤,位居女性恶性肿瘤第二位。我国宫颈癌发病率和死亡率占全世界的1/3。宫颈癌病因学研究结果已证实,人乳头瘤病毒（HPV）感染是其发生的主要致病因素,迄今已发现120多种HPV亚型,依据其致病力大小,将HPV亚型分为低危型和高危型两类。基因芯片是近年发展起来的对病原体核酸进行高通量快速的检测方法,主要可用于HPV分型检测[1],本文旨在进一步了解HPV亚型与宫颈病变的关系。     

人乳头瘤病毒与宫颈上皮内瘤样病变术后复发的关系

宫颈上皮内瘤样病变（CIN）是一种癌前病变,可分为CINⅠ、CINⅡ和CINⅢ。国内对CINⅡ及以上者主要采取手术治疗,但术后仍有一定的复发率。影响复发的因素较多,包括切缘阳性、宫颈管诊刮阳性、机体免疫力降低、高龄等。人乳头瘤病毒（HPV）与CIN复发的关系尚不十分明确,但基本能够确定HPV持续感染可增加CIN复发率,且HPV亚型和HPV负荷量在其中起重要作用。综述HPV对CIN复发的影响。

Immunocompetent cells in uterine cervical lesions of human papillomavirus origin

To elucidate the local immunological reactions operative in the human papillomavirus (HPV)-induced lesions of the uterine cervix, a total of 150 cervical biopsies containing a dysplastic or a neoplastic change with (CO, 97 cases) or without (NCO, 53 cases) a coexistent HPV lesion (a flat, an inverted or a papillomatous condyloma) were subjected to ANAE (acid alpha-naphthyl acetate esterase) staining of the immunocompetent cells; B and T lymphocytes, mononuclear phagocytes (MPS cells). In addition, HPV antigens were demonstrated by an indirect immunoperoxidase-PAP method. Age of the patients did not influence the proportions of B, T and MPS cells. Degree of epithelial atypia was inversely related to proportion of B cells in NCO but not in CO series, and directly related to proportions of T cells in CO series, the latter T cell increase being most probably ascribable to the appearance of suppressor T cells. Unlike in the different types of skin warts (caused by divergent HPV types), the type of the cervical condyloma did not affect the proportions of B, T and MPS cells, suggesting a common HPV type as a causative agent of the latter. MPS and T cells were more numerous in HPV-positive condylomas than in HPV-negative ones, supporting the concept that cell-mediated immune mechanisms recognize the surface antigens of the virus-transformed cells coded by the viral genome in the host cell nuclei (HPV+). The findings are discussed in terms of the immune mechanisms involved in rejection of HPV lesions in general, and those of the uterine cervix especially. The full significance of these mechanisms can only be understood when adequate follow-up data of the lesions are at hand.     

Human papillomavirus and cervical lesions

Human papillomavirus (HPV) infection has been implicated in the intraepithelial cervical changes that cause most abnormal Papanicolaou smears. To date, 14 types of HPVs have been identified. All are small, nondeveloped, icosahedral DNA viruses that share a common internal antigen. In cases of cervical HPV infection, the koilocytes and dyskeratocytes are the most frequently seen cell types. Most infections are flat aceto-white lesions. Florid condyloma acuminatum, usually detectable with the naked eye, is characterized by an irregular surface secondary to finger-like projections, in the middle of which a capillary loop comes to the surface. Spiked condyloma, not seen with the naked eye, has an irregular surface that shows asperity. 3 techniques have been used to differentiate atypical condyloma from intraepithelial neoplasia: microspectrophotometric studies, the peroxidase- antiperoxidase technique, and electronmicroscopy. There is growing evidence that papillomaviruses play an etiologic role in human genital cancer. 20-25% of dysplastic and neoplastic lesions show a coexistence of condylomas of the cervix or vulva with dysplasia or neoplasia. Epidemiologic research suggests that cervical condylomas occur at a mean age of 27.5 years, precede cervical dysplasia by 3.3 years, carcinoma in situ by 9.3 years, and invasive carcinoma by 27.4 years. The conversion of most cases of papillomas into squamous cell carcinomas requires the presence of carcinogenic initiators, 1 of which is believed to be herpes simplex virus.     

High-risk human papillomavirus DNA testing and high-grade cervical intraepithelial lesions

OBJECTIVE: To explore the role of high-risk human papillomavirus (HPV) DNA testing in the improvement of the recognition of cervical cancer and precancerous lesions in women with abnormal cervical cytology. METHODS: A total of 2152 women with abnormal cervical cytology were submitted to both HPV DNA testing and biopsy guided by colposcopy and the results were correlated. RESULTS: Positive rate of high-risk HPV DNA in groups of atypical squamous cells of undetermined significance (ASC-US), atypical squamous cells, cannot exclude high-grade (ASC-H), low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions was 53.7, 53.2, 84.6 and 93.0%, respectively. In each group, the detection rate of grade 2,3 cervical intraepithelial neoplasia (CIN 2,3) or cervical cancer in patients with positive HPV DNA was significantly higher than that with negative HPV DNA (P<0.05). In ASC-US group, the negative predictive value of high-risk HPV DNA testing for detection of CIN 2,3 and cervical cancer was 99.8% and the sensitivity 98%. CONCLUSION: HPV DNA testing is a useful indicator in the management of patients with ASC-US and plays an important role in the evaluation of risk for CIN 2,3 and cervical cancer.     

Viral load of high-risk human papillomavirus in cervical squamous intraepithelial lesions.

OBJECTIVES: This case-control study was conducted to investigate the role of viral load of high-risk human papillomaviruses (HPVs) in the development of cervical squamous intraepithelial lesions (SILs) and invasive cancers. METHODS: A total of 30 female cases who had histological evidence of low-grade SIL (n=10) or high-grade SIL and above (n=20) were identified as the case group at the Tri-Service General Hospital, Taipei between September 1998 and March 1999. In addition, 80 female controls who had normal cervical cytology were enrolled and individually matched on age (+/-5 years) and date of recruitment to each case. Cervical swabs collected from study subjects were tested for the positivity and viral load of high-risk HPVs by Hybrid Capture II assay. Additionally, subjects completed a risk factor questionnaire. RESULTS: Among sex behavioral factors studied, younger age at first intercourse was associated with a significantly elevated risk of cervical SIL and invasive cancers. With respect to HPV infection, high-risk HPV DNA was present in 70% (21/30) of case and 21% (17/80) of control subjects, resulting in an odds ratio (OR) of 6.6 [95% confidence interval (C.I.)=2.6-17.0]. Moreover, women who had a high viral load were at significantly greater risk for cervical SIL and invasive cancers than those who were infected with a low viral load (OR=18.0, 95% C.I.=3.0-108.5). CONCLUSIONS: Among the variables tested, infection with a high viral load of high-risk HPVs is the strongest determinant for cervical SIL and cervical cancers in Taiwan.     

Prevalence of human papillomavirus infection and correlation with cervical lesions in Japanese women

PURPOSE: To investigate the prevalence of human papillomavirus (HPV) infection in patients attending a gynecologic outpatient department, and to correlate the infection status with the presence or absence of uterine cervical lesions and the grades assessed by cytological or histological examinations. METHODS: Five hundred and seventy-two subjects were studied. In all subjects, HPV detection by the hybrid capture method and a cervical cytological examination were performed RESULTS: The HPV-positive rate in subjects with normal cytology was 12.3%. The detection rate was high (21.7%) in subjects aged in the twenties and low in the forties, and HPV was not detected in subjects aged in the sixties and seventies. When HPV-positive rates were examined according to cytological or histological grades, the rates were higher in subjects with abnormal cytology (P < 0.01) or cervical intraepithelial neoplasia (CIN) or squamous cell carcinoma compared with those with normal cytology. CONCLUSION: Diagnosis of HPV infection is also important for the prediction of progression to CIN and cervical cancer.     

Detection of human papillomavirus DNA in human cervical lesions by tissue in situ nucleic acid hybridization

Cervical cancer is one of the most common female cancers in Taiwan. Certain types of human papillomavirus (HPV) are frequently detected in the epithelial precancerous and cancerous lesions of the cervix. By the use of tissue in situ hybridization, we investigated the relationship of various types of HPV (group I, HPV-6 & 11, group II, HPV-16 & 18, group III, HPV-31, 33 & 35) with cervical condyloma, carcinoma as well as precancerous lesions. Group I HPV DNAs were mainly found in cervical condylomatous lesions (2/2) of the cervix and cervical intraepithelial neoplasia I (CIN I) (2/4), but were only occasionally found in CIN II (1/4), CIN III (1/9) or non-keratinized squamous cell carcinoma (1/15). HPV DNAs of groups II and III were mainly detected in lesions of CIN III (5/9) and invasive squamous cell carcinoma (large cell, keratinized type: 4/7; large cell, non-keratinized type: 11/15). HPV DNA sequences were invariably detectable only in the cell nuclei of condyloma or dysplastic epithelium or invasive carcinoma. However, they could not only be detected in the upper layer dysplastic cells and koilocytes but also in the well and poorly differentiated cervical cancer cells. The distribution of HPV DNA positive cells in the carcinomas fell into four different patterns: (1) upper zone and non-invasive regions of the carcinoma (11/22, 50%), (2) basal zone and invasive regions (2/22, 9%), (3) randomly scattered (7/22, 32%), and (4) extensively distributed over the whole tumor lesions (2/22, 9%). Thus, our results are consistent with a strong correlation between the presence of HPV-16, 18, 31, 33 and 35 and malignant conversion of cervical epithelial cells.     

Factors predicting human papillomavirus clearance in cervical intraepithelial neoplasia lesions treated by conization

OBJECTIVE: The objective was to identify the factors, if any, that may predict long-term results of CIN treatment and HPV clearance/persistence after locally excisional therapy. METHODS: A series of 252 women with CIN lesions treated by conization were subjected to sequential HPV detection by repeated PCR during the prospective posttreatment follow-up. Factors predicting viral clearance during the follow-up (10.26 months) were elaborated using univariate and multivariate statistical techniques applied on epidemiological, clinical and biological data of the lesions. RESULTS: Sensitivity of the PAP test in detecting high-grade lesions was 93.9%, and specificity 27.3%. Odds ratio for having CIN 3/Stage IA1 squamous cervical cancer in the cone with HSIL PAP test was 5.69; 77.8 and 22.2% residual disease were found among PCR-positive and -negative cases, respectively. HPV DNA was negative in 74/252 (29.8%) samples at the first PCR. Multivariate logistic regression analysis showed that HPV 16 was an independent explanatory factor for high-grade CIN (P = 0.0001). HPV clearance increased to 63.5% at completion of the follow-up, corresponding to the monthly clearance rate of 5.27%. In Kaplan-Meier analysis, the highly significant (P = 0.0001) predictors of HPV clearance/persistence were age, lesion grade in the biopsy, lesion grade in the cone, volume of the cone, length of active sexual life, and involvement of endocervical margin (P = 0.0013). In chi-square tests, high-risk HPV type (P = 0.001) was such a predictor. In multivariate (Cox) model, the significant independent predictors of HPV clearance were involved endocervical margin (P = 0.001), lesion grade in the cone (P = 0.004), high-grade lesion in the colposcopic biopsy (P = 0.023), age (P = 0.029), and HSIL in PAP smear (P = 0.029). CONCLUSIONS: These data suggest that posttreatment follow-up should include both the PAP test and HPV detection techniques for early detection of any patients at increased risk for disease recurrence and progression, because of persistent oncogenic HPV types.
