目的探讨妊娠合并子宫颈上皮内瘤变患者高危型人乳头状瘤病毒(HPV)感染情况。方法将2011年11月至2012年10月间收治的118例妊娠合并子宫颈上皮内瘤变患者(实验组)和118例宫颈健康的妊娠女性(对照组)作为研究对象,比较两组高危型HPV的感染情况。结果妊娠合并宫颈上皮内瘤变(CIN)患者感染的HPV主要类型为HPV16和HPV18,两者在宫颈癌发生发展中可能起重要作用,宫颈病变的级别与HPV的阳性率和载荷量呈显著正相关,两者可以作为妊娠合并CIN患者早期诊断的临床指标之一。结论妊娠合并子宫颈上皮内瘤变患者的高危型HPV感染可以作为诊断宫颈癌的重要要指标,值得临床大力推广。 相似文献

目的:分析宫颈上皮内瘤变( CIN)及宫颈癌( CC)中人乳头状瘤病毒( HPV)亚型,探讨HPV感染与宫颈病变的相关性。方法:慢性宫颈炎或液基细胞学异常的妇女检测21种HPV基因亚型和阴道镜下宫颈定位活检,分析2481例CC和CIN患者的HPV感染情况。结果:在2481例CIN和CC患者中,HPV感染率85.0%,HPV感染与宫颈组织学结果有较强的相关性(P〈0.001,Pearson列联系数=0.648)。 CC及CINⅢ、CINⅡ患者以HPV16、18感染最多见,其次见HPV58、33、31、52、45、59、68等亚型。304例患者宫颈感染HPV16、18、58、52、33等亚型后,发生高度鳞状上皮内病变(HSIL)、不明意义的非典型鳞状细胞(ASCUS)及低度鳞状上皮内病变(LSIL)的频率增加,TCT分型与HPV分型有较弱的相关关系(P=0.002,Pearson列联系数=0.322)。细胞学结果提示HSIL、AS-CUS,宫颈组织学诊断以CC、CINIII和CINII为多,TCT分型与组织学分型也有较弱的相关性( P=0.026,Pearson列联系数=0.172)。结论:HPV16、18、58、33、52、31、45等高危型HPV感染是宫颈癌( CC)及癌前病变( CIN)最常见的风险因素。高危型HPV单独或混合感染宫颈后,细胞学检测HSIL、ASCUS及LSIL的发生率增加,细胞学结果与组织学分型的相关性促进了CC和CIN的及时诊治。 相似文献

BACKGROUND: In cervical lesions, the overexpression of p16 is reported to be closely associated with high-risk human papillomavirus (HPV) infection. The objective of the current study was to confirm the usefulness of liquid-based cervical specimens for p16 staining as well as tissue sections. METHODS: A total of 98 patients with cervical lesions were entered into the current study. After the cytologic examination using liquid-based cervical smears, the same slides were immunostained for p16 and were compared with slides of simultaneously obtained, immunohistologically stained tissue sections. Moreover, the status of the HPV infection was examined by polymerase chain reaction using residual cytologic samples. RESULTS: Using liquid-based Pap smears, 98 cases were diagnosed as atypical squamous cells of undetermined significance (38 cases), low-grade squamous intraepithelial lesion (12 cases), high-grade squamous intraepithelial lesion (HSIL) (33 cases), and invasive carcinoma (15 cases). The concordance rate between the cytologic and histologic diagnoses was found to be higher in high-grade lesions compared with low-grade lesions. Immunohistochemistry revealed that all HSIL and invasive carcinoma cases contained p16-positive cells in the liquid-based Pap smears and diffuse p16 staining was observed in all high-grade lesions with greater than CIN Grade 3 cervical intraepithelial neoplasia except for two adenocarcinoma cases. Of the 98 cases, 60 were found to be positive for high-risk HPV and 55 of these 60 HPV-positive cases were found to be p16 positive on cytologic examination. There were 16 cases that demonstrated marked discrepancies between the cytologic and histologic diagnoses. CONCLUSIONS: The results of the current study confirmed that the immunohistochemical detection of p16 was more sensitive and specific than HPV status in cervical lesions using a liquid-based method as well as tissue samples, suggesting that p16 should be used as a satisfactory biomarker for the primary screening of cervical cytology. 相似文献

目的 人乳头瘤病毒(human papillomavirus,HPV) DNA能提高检测宫颈上皮内瘤变2级+(cervical intraepithelial neoplasia 2+,CIN2+)的灵敏度,但也增加了一过性HPV感染的检出率.本研究应用高危型HPV(high risk human papillomavirus,hrHPV) E6/E7 mRNA对比二代杂交捕获(hybrid CaptureⅡ,HC2)、HPV分型,描述机会性筛查人群中HPV感染及宫颈病变分布特征,探讨其用于宫颈筛查的可行性.方法 选取2013-01-01-2015-12-31在青岛大学附属青岛市立医院(6 138例)和青岛市城阳区人民医院(1 653例)妇科门诊行宫颈液基细胞学筛查的女性共计7 791例,年龄21~65岁.所有筛查女性行液基细胞学检查的同时行HPV检测,根据HPV检测方法的不同分为HC2组、HPV分型组和E6/E7组共3组.计算各组细胞学结果异常率、HPV阳性率和宫颈病变检出率,比较E6/E7所描述的流行病学特征与HPV-DNA方法的不同.结果 E6/E7组各级细胞学结果分别为,未见上皮内瘤变及恶性病变(negative for intraepithelial lesion or malignancy,NILM) 87.51%,意义不明的非典型鳞状细胞(atypical squamous cells of undetermined significance,ASCUS)5.47%,低级别鳞状上皮内瘤变(low-grade squamous intraepithelial lesion,LSIL)3.51%,不除外高级别鳞状上皮内瘤变的非典型细胞(atypical squamous cells cannot exclude HSIL,ASC-H)0.52%,高级别鳞状上皮内瘤变(high-grade squamous intraepithelial lesion,HSIL)2.99%.HPV阳性中异常细胞学结果的比例明显高于HPV阴性,而NILM的比例低于HPV阴性,P<0.001.随着细胞学异常程度的加重,HPV阳性率逐渐增高,差异有统计学意义,x2值分别为611.089、512.036和767.260,P值均<0.001.E6/E7组中NILM的HPV阳性率为8.02%,合计阳性率为14.73%,均较HC2及分型组低,x2=30.174,P=0.000;x2 =22.991,P<0.001. E6/E7组CIN2+/CIN3+检出率分别为5.92%和1.20%,3组间比较差异无统计学意义,x2值分别为1.499和0.711,P值分别为0.473和0.701.E6/E7阳性率在正常至浸润性宫颈癌(invasive cervical cancer,ICC)之间随病变程度加重而升高,P<0.05.在正常病理结果中E6/E7阳性率为61.36%,低于HC2和HPV分型,x2=15.767,P<0.001;其余病理结果中各组间HPV阳性率差异无统计学意义,P>0.05.结论 hrHPV E6/E7 mRNA较之HC2和HPV分型能在不降低宫颈病变检出率的前提下减少一过性HPV感染的检出率,提示其在宫颈筛查中具有潜在应用价值. 相似文献

BACKGROUND: Testing for human papillomavirus (HPV) is an integral part of equivocal cervical cytology triage. Clinical validation of non-FDA (Food and Drug Administration)-approved methods is therefore important because of the high volume of such tests and the implications for missed high-grade lesions if test performance is not optimal. METHODS: A preinitiation study and 17 months of follow-up data using Hybrid Capture II (HC II) HPV detection with SurePath (SP) sample collection were analyzed. Results of HPV tests on abnormal cytology samples were collected and compared with follow-up results. HPV-positive rates were determined in cases of low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL), and follow-up rates of cervical intraepithelial neoplasia (CIN) were determined in HPV-positive and -negative cases of atypical squamous cells of unknown significance (ASC-US). Rates were compared with published data using FDA-validated methods. RESULTS: The preinitiation study showed the test method to be 100% sensitive for the detection of LSIL (20 cases) and HSIL (8). The ASC-US follow-up study (2319 cases with 625 having biopsy results) showed that the rate of CIN III+ in HPV +/- cases was 7.8%/1.4%, and of CIN II+ was 17.5%/4.3%, respectively. The positive predictive values/negative predictive values (PPV/NPVs) (CIN II+) for the test were 17.5%/95.7%, respectively. CONCLUSIONS: Published FDA-validated HPV testing follow-up data show that the expected rates of CIN III+ and CIN II+ in the HPV-negative ASC-US population are 1.4% and 5%, respectively, with PPV/NPVs (CIN II+) of 20%/99%, respectively. By comparison, the present data using HC II with SP show strong similarity, indicating clinical validity for the use of this method. 相似文献

Human papillomavirus (HPV) testing is very sensitive for primary cervical screening but has low specificity. Triage tests that improve specificity but maintain high sensitivity are needed. Women enrolled in the experimental arm of Phase 2 of the New Technologies for Cervical Cancer randomized controlled cervical screening trial were tested for high-risk HPV (hrHPV) and referred to colposcopy if positive. hrHPV-positive women also had HPV genotyping (by polymerase chain reaction with GP5+/GP6+ primers and reverse line blotting), immunostaining for p16 overexpression and cytology. We computed sensitivity, specificity and positive predictive value (PPV) for different combinations of tests and determined potential hierarchical ordering of triage tests. A number of 1,091 HPV-positive women had valid tests for cytology, p16 and genotyping. Ninety-two of them had cervical intraepithelial neoplasia grade 2+ (CIN2+) histology and 40 of them had CIN grade 3+ (CIN3+) histology. The PPV for CIN2+ was >10% in hrHPV-positive women with positive high-grade squamous intraepithelial lesion (61.3%), positive low-grade squamous intraepithelial lesion (LSIL+) (18.3%) and positive atypical squamous cells of undetermined significance (14.8%) cytology, p16 positive (16.7%) and, hierarchically, for infections by HPV33, 16, 35, 59, 31 and 52 (in decreasing order). Referral of women positive for either p16 or LSIL+ cytology had 97.8% sensitivity for CIN2+ and women negative for both of these had a 3-year CIN3+ risk of 0.2%. Similar results were seen for women being either p16 or HPV16/33 positive. hrHPV-positive women who were negative for p16 and cytology (LSIL threshold) had a very low CIN3+ rate in the following 3 years. Recalling them after that interval and referring those positive for either test to immediate colposcopy seem to be an efficient triage strategy. The same applies to p16 and HPV16. 相似文献
