目的:初步探讨Brn-3a在HPV所致各级别宫颈病变中的表达及不同HPV亚型与Brn-3a表达的关系,探讨其作为CIN诊断和治疗标志物的可行性。方法:按照入组标准选取研究期间在我院就诊的月经正常、有性生活史的妇女97例为研究对象。对同一位患者的宫颈脱落细胞同时进行转录因子Brn-3a的表达及HPV分型的检测。分析每组样本Brn-3a的表达。结果:Brn-3a表达随着病变加重而升高。高级别CIN(CINⅡ、Ⅲ及原位癌)LEEP术后随访组Brn-3a表达高于宫颈良性病变(HPV-)组,差异有统计学意义(P=0.0000,<0.05);该组平均值虽高于HPV感染(HPV+)、宫颈湿疣与CINⅠ组,但二者无统计学差异(P=0.6815,>0.05);与高级别CIN组(治疗前)相比,表达量明显减少,差异有统计学意义(P=0.0002,<0.05)。不同HPV亚型所致的同级别病变中Brn-3a表达差异无统计学意义;高危型和低危型HPV感染所致的CINⅠ以下病变组中,Brn-3a表达无统计学差异(P=0.5815);同种HPV亚型所致的不同病变级别Brn-3a表达有统计学差异。结论:转录因子Brn-3a表达与HPV所致宫颈病变的病理级别相关,并非简单的反映HPV的感染状态。     

Detection and quantitation of human papillomavirus type 16, 18 and 52 DNA in the peripheral blood of cervical cancer patients

OBJECTIVE: To prospectively evaluate the feasibility of detecting human papillomavirus (HPV) type 16, 18 and 52 DNA in the peripheral blood of patients with cervical cancer using real-time polymerase chain reaction (PCR) and to determine its prognostic importance. METHODS: Blood and cervical swab specimens from 135 consecutive patients with 60 invasive cervical cancers, 10 microinvasions, 20 cervical intraepithelial neoplasias (CIN) III, 10 CIN II, 10 CIN I and 25 controls were collected and examined for HPV type 16, 18 and 52 DNA using real-time PCR to investigate the prevalence and viral load of HPV DNA at the time of diagnosis and during follow-up in patients with positive blood samples. RESULTS: Of the 60 patients with invasive cervical cancer, 27% had positive test results for HPV DNA in blood samples in contrast to 0% of patients with microinvasions, CIN III, CIN II, CIN I and normal controls. The DNA detection rates of viral subtypes in blood samples of cervical cancer patients were 5% for HPV-16, 16.7% for HPV-18, 8.3% for HPV-52, 1.7% for both HPV-16 and HPV-18 and 1.7% for both HPV-18 and HPV-52, while the detection rates in cervical swab specimens were 36.2% for HPV-16, 15.5% for HPV-18 and 17.2% for HPV-52. During follow-up, 8 of 10 cervical cancer patients with viral DNA detected in blood within 3 months after treatment had recurrence, and a high percentage (87.5%, 7/8) of this recurrence involved distant metastases. CONCLUSIONS: In this study, real-time PCR detected HPV-16, -18 or -52 DNA in the peripheral blood of more than one-fourth of invasive cervical cancer patients. The association between risk of cancer recurrence and the amount of viral DNA detected in blood among cervical cancer patients after treatment is intriguing and deserves further investigation.     

HPV oligonucleotide microarray-based detection of HPV genotypes in cervical neoplastic lesions

BACKGROUND: In this study we examined the use of a new-human papillomavirus (HPV) detection method, the HPV oligonucleotide microarray system (Biomedlab Co., Korea), which we compared with the well-established HPV DNA detection system (Hybrid Capture II; HC-II, Digene Co.). This new method prompted us to develop a new HPV genotyping technique, using the oligonucleotide microarray, to detect the generic and type-specific sequence of HPV types. In particular, we undertook the evaluation of the clinical efficacy of the HPV oligonucleotide microarray for detecting HPV in cervical neoplastic lesions. METHODS: One hundred forty patients were involved and classified into three groups according to their histopathologic diagnoses: Group I (nonspecific chronic cervicitis; n = 61), Group II (low-grade squamous intraepithelial lesion (SIL); koilocytosis, and mild dysplasia; n = 39), and Group III (high-grade SIL; moderate, severe dysplasia and in situ carcinoma; n = 40). Cytological diagnoses were based on the Bethesda System and cervical samples were analyzed by the two methods. The HPV oligonucleotide microarray detected 15 types of high-risk HPV (HPV-16/-18/-31/-33/-35/-39/-45/-51/-52/-56/-58/-59/-66/-68/-69) and 7 types of low-risk HPV (HPV-6/-11/-34/-40/-42/-43/-44). RESULTS: In 105 of the 140 cervical samples (75%), HPV DNAs were examined using the HC-II method. HPV detection rates using the HPV microarray agreed with those of HC-II. One HC-II-positive, but HPV microarray-negative, case occurred in the low-grade SIL (Group II) and was later confirmed negative for HPV. The other HPV microarray-positive but HC-II-negative case was found to be HPV-18 by PCR. Low-risk types of HPV were detected in 3 of 39 low-grade SIL cases (Group II) using the HPV microarray. HPV-16 was the most frequent type (32.1%) in all specimens tested, and was significantly more frequent in low-grade or high-grade intraepithelial lesions (Groups II or III) than in normal controls (Group I) (P < 0.05). HPV-58 was the second most common type (17.5%) in Group III. The HPV microarray was found to have advantages in terms of identifying the HPV genotypes and cases of multiple HPV infection. Double HPV infections were detected in 12 cases and triple HPV infections in 7 cases. Two cases were positive for four types of HPV (HPV-16/18/33/35, HPV-16/18/58/68). The sensitivity of HPV testing (HC-II; 94.9%, HPV microarray; 93.7%) for identifying patients with squamous intraepithelial lesion was significantly better than the sensitivity of cytology (77.1%, P < 0.05). On using multiple logistic regression analysis to estimate the relative risk of SIL versus HPV type, HPV-16-positive cases were found to have a 7.5-fold risk of SIL (95% CI = 3.28-16.51; P < 0.01). HPV-33 and HPV-58 were found to be significantly related to high-grade SILs (P < 0.01). CONCLUSIONS: Our results suggest that the HPV oligonucleotide microarray is highly comparable to HC-II for detecting HPV in cervical specimens. The HPV oligonucleotide microarray provides useful information on viral genotype and multiple HPV infections in HPV-related cervical lesions. Genetic information on HPV in cervical specimens might be a particular benefit of the new procedure in the management of cervical neoplastic lesions     

Human papillomavirus infection and cervical disease in human immunodeficiency virus-1-infected women

OBJECTIVE: To report on the natural history of high-risk human papillomavirus (HPV) infection and cervical disease in human immunodeficiency virus (HIV)-1-infected women living in Cape Town, South Africa. METHODS: This was a prospective study of 400 untreated, HIV-1-infected women who underwent high-risk HPV DNA testing, cytology, colposcopy, histology, and CD4 count testing every 6 months for 36 months. Human immunodeficiency virus viral loads and HPV type distribution were determined at entry and after 18 months. RESULTS: Sixty-eight percent of the women were high-risk HPV DNA positive at entry, 35% had a cytologic diagnosis of low-grade squamous intraepithelial lesion (LSIL), and 13% had high-grade squamous intraepithelial lesion (HSIL). There were no cancers. Abnormal cytology and high-risk HPV positivity were strongly correlated with low CD4 counts and high HIV viral loads. The most prevalent types of HPV were HPV-16, -52, -53, -35, and -18. Incident high-risk HPV infection occurred in 22%, and of those infected with high-risk HPV, 94% of infections persisted over an 18-month period, and 6% cleared their infections. Cytologic progression to SIL from normal/atypical squamous cells of undetermined significance cytology occurred in 17% of cases, but only 4% of cases of LSIL progressed to HSIL. CONCLUSION: There is a high level of high-risk HPV infection in HIV-1 infected women, but progression to HSIL over 36 months occurred in the minority of cases. We recommend an initial colposcopy for an abnormal test, and if no high-grade lesion is identified, triennial screening would be appropriate. Human papillomavirus type 16 was the commonest, and HPV-18 was the fifth commonest, suggesting that vaccination against these two types would have a significant effect. LEVEL OF EVIDENCE: II.     

Prevalence of HPV infection by cervical cytologic status in Brazil

Objectives

To assess the prevalence of human papillomavirus (HPV) infection according to cervical cytologic status in northeastern Brazil; identify other risk factors for low- and high-grade squamous intraepithelial lesions (LSILs and HSILs); and identify the most prevalent HPV genotypes associated with the lesions.

Method

Two cervical smears were collected from 250 women referred for cancer screening, one for cytologic examination and the other to test for the presence of HPV by PCR with genotyping by dot blot hybridization.

Result

There were 110 healthy cervices, 82 LSILs, and 58 HSILs. The overall HPV prevalence was 48%, with higher rates for HSILs, and HPV-16 was the most prevalent type. Age, multiple sexual partners, type of HPV present, smoking, and early onset of sexual activity were risk factors for cervical lesions.

Conclusion

Age, multiple sexual partners, and infection with HPV-16 increased the risk of having LSILs or HSILs. Early onset of sexual activity and smoking only increased the risk of having HSILs.

Objective

Data concerning HPV infection in cervical cancer are globally lacking in Saudi Arabia. Therefore, the aim of this study was to assess HPV prevalence and genotypes' distribution in invasive cervical cancer in our patients to provide baseline information for screening and prevention.

Methods

The study included 100 paraffin-embedded cervical tumors. HPV genotyping was performed using the Linear Array kit (Roche Diagnostic) that enables the concomitant detection of 37 mucosal HPVs including 13 most common high-risk viruses.

Results

Eighty-nine specimens were HPV-positive. Eleven different HPV genotypes were detected, 8 high risk (16, 18, 31, 39, 45, 51, 59, 73) and 3 low risk (6, 64, 70). Ten patients had double infections involving mainly HPV-16 and 18. The most common genotypes were 16 (65.2%), 31 (7.9%), 45 (6.7%), 18 (3.4%), and 73 (2.3%). However, by considering double infections, HPV-18 became the second most common genotype (10.1%). The patients' median age was significantly lower (P = 0.028) in HPV-16/18 infected group compared to other genotypes (44, range 32-76 vs. 49, range 38-67).

Conclusions

Eighty-nine percent of cervical cancers in Saudi Arabia were associated with HPV infection, and 78.7% (70/89) of HPV-positive tumors were infected with HPV-16/18, which caused the cancer to appear 5 years earlier than the combined HPV-negative and other HPV genotypes (P = 0.013).
