SUMMARYWe conducted a systematic review summarizing data on incidence of high- and low-grade lesions in women with normal baseline cervical cytology, stratified by age (<30 and ⩾30 years), and baseline human papillomavirus (HPV) infection. Incidence of high- and low-grade lesions in women aged ⩾30 years with a baseline HPV infection increased over follow-up time (5–127 months), although incidence generally remained <10%. Without baseline HPV infection, incidence of high-grade lesions remained low over follow-up time (<5% over 5–122 months). Incidence of high-grade lesions in women aged ⩾30 years with baseline HPV infection appeared similar to that in women aged <30 years. In some women aged <30 years, high-grade lesions can develop relatively shortly after initial HPV infection. We observed an increase in low-grade lesions over time in women aged ⩾30 years with baseline HPV infection, potentially indicative of an HPV infection that is potentially progressing to higher grade lesions.

212 females attending a genitourinary medicine (GUM) clinic with first episode anogenital warts were screened by cervical cytology and colposcopy/histology for the presence of cervical epithelial abnormalities in keeping with infection by the human papillomavirus (HPV infection) and/or cervical intraepithelial neoplasia (CIN). The prevalence of cervical epithelial abnormalities detected by cervical cytology alone was 32%, rising to 56% after colposcopic examination. However, the majority of cervical lesions detected by colposcopy alone were of low grade (HPV infection and/or CIN I). Histologically confirmed high grade cervical lesions (CIN II or CIN III) were detected more frequently in those females in whom cervical cytological examination indicated dyskaryosis in keeping with any grade of CIN, compared to females without dyskaryotic changes on cervical smear ( P<0.05, chi-squared test with Yates' correction). Early colposcopy is indicated for females with anogenital warts in the presence of a cervical smear showing dyskaryosis in keeping with any grade of CIN, because of the statistically significant increased risk of detecting a potentially progressive high grade cervical lesion. In females without dyskaryotic changes on cervical smear, the value of early colposcopy is uncertain and warrants larger more long-term trials.

ObjectiveHIV infection increases the risk of high-grade cervical neoplasia and invasive cervical carcinoma. The study addresses the limited data describing human papillomavirus (HPV) infection and cervical neoplasia among HIV-infected women in HIV-discordant relationships in sub-Saharan Africa, which is needed to inform screening strategies.MethodsA cross-sectional study of HIV-infected women with HIV-uninfected partners was conducted to determine the distribution of type-specific HPV infection and cervical cytology. This study was nested in a prospective cohort recruited between September 2007 and December 2009 in Nairobi, Kenya. Cervical cells for HPV DNA testing and conventional cervical cytology were collected. HPV types were detected and genotyped by Roche Linear Array PCR assay.ResultsAmong 283 women, the overall HPV prevalence was 62%, and 132 (47%) had ≥1 high-risk (HR)-HPV genotype. Of 268 women with cervical cytology results, 18 (7%) had high-grade cervical lesions or more severe by cytology, of whom 16 (89%) were HR-HPV-positive compared with 82 (41%) of 199 women with normal cytology (p<0.001). The most common HR-HPV types in women with a high-grade lesion or more severe by cytology were HPV-52 (44%), HPV-31 (22%), HPV-35 (22%), HPV-51 (22%) and HPV-58 (22%). HR-HPV genotypes HPV-16 or HPV-18 were found in 17% of women with high-grade lesions or more severe. HR-HPV screening applied in this population would detect 89% of those with a high-grade lesion or more severe, while 44% of women with normal or low-grade cytology would screen positive.ConclusionHR-HPV prevalence was high in this population of HIV-infected women with an uninfected partner. Choice of screening for all HR genotypes versus a subset of HR genotypes in these HIV-infected women will strongly affect the performance of an HPV screening strategy relative to cytological screening. Regional and subpopulation differences in HR-HPV genotype distributions could affect screening test performance.

AbstractTelomerase Reverse Transcriptase (TERT) is the main catalytic sub-unit of telomerase, a reverse transcriptase enzyme. Telomerase expression is regulated at many levels, with numerous studies suggesting that up-regulation of human TERT gene (hTERT) at transcriptional level results in immortal cell phenotype associated with cancer. The aim of this study is to determine the correlation between hTERT expression and different cervical precursor lesions, as well as with cervical cancer in patients with confirmed Human papillomavirus (HPV) infection.The study included molecular analyzes on cervical samples from 214 women and matched Papanicolaou (Pap) test results. HPV detection and genotyping was performed by polymerase chain reaction (PCR) and genotyping. Quantitative real-time PCR (qRT-PCR) was performed using TaqMan probes and were calculated relative to the reference gene.Results showed significantly increased hTERT mRNA expression levels in high-grade and low-grade lesions compared to normal control samples (p<0.01) associated with 6.31 fold higher risk for developing ASC-US and 9.20 for LSIL. Strong correlation between HPV infection and hTERT expression in the high-grade lesions and cervical cancer was also observed. hTERT relative expression values showed 98% specificity and 100 % sensitivity as indicator of cervical lesions particularly for the ACS-H, HSIL and cervical cancer. In conclusion, hTERT expression correlate with the cytological grade of the cervical lesions and HPV infection and has a potential to be used as a diagnostic and prognostic marker.

Abstract Background: High-risk human papillomavirus (HR-HPV) infection is widely known as the major cause of cervical intraepithelial neoplasia (CIN) and cervical cancer and it’s characteristics vary greatly in different population. Women with abnormal cervical cytology could increase the risk of cervical cancer, however, HR-HPV infection characteristics in women with abnormal cervical cytology remains unclear. Methods: This study was based on baseline survey of the CIN Cohort established in Shanxi Province, China. A total number of 2300 women with cervical abnormalities were enrolled in this study. All participants gave informed consent and agreed to HPV and thinprepcytologic test (TCT). Each individual completed a questionnaire about characteristics related to HPV infection. Results: The overall prevalence of HR-HPV in 2300 women was 32.0%, and the proportion of single and multiple HR-HPV infections were 70.2% and 29.8% in HR-HPV infection women, respectively. The top five HR-HPV genotypes were ranked as HPV16, HPV58, HPV52, HPV53 and HPV51. The prevalence of HR-HPV in atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion and above(HSIL+) were 30.8%, 36.5% and 54.9%, respectively, showing an increasing trend with the severity of cervical cytology ( χ 2 trend =13.952; p <0.001). The women aged 35~45 years, with lower education level, less frequency of bathing, multiple gravidity, multiple parity, history of gynecological diseases and premenopausal women were prone to HR-HPV infection. Conclusions: We defined the characteristics related to HR-HPV infection in abnormal cervical cytology women, and provided an insight for the development and deeply research of HPV vaccine.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

Reporting Rates

Abstract Context.—The 2001 Bethesda System for the reporting of cervical cytology specimens and the use of new liquid-based and human papillomavirus testing technologies have led to changes in cervical cytology reporting practices. Objectives.—To analyze current laboratory reporting practices using Bethesda 2001 terminology and to compare results with previous survey data from 1996. Design.—Questionnaire survey mailed to 1751 laboratories in mid-2003. Participants.—Laboratories enrolled in the College of American Pathologists Interlaboratory Comparison Program in Cervicovaginal Cytology. Results.—Of the 759 responding laboratories, most (85.5%) had implemented Bethesda 2001 terminology, and the majority had adopted major changes, such as elimination of the benign cellular changes category and the satisfactory but limited category. The median reporting rate for low-grade squamous intraepithelial lesion was 2.1%, compared to a 1996 median rate of 1.6%, but the increase was confined to liquid-based preparations. Reporting rates for high-grade squamous intraepithelial lesion (median, 0.5%) and atypical squamous cells (ASC) had changed little. Most ASC cases were subclassified as “undetermined significance” (median, 3.9%) with ASC, cannot exclude high-grade SIL accounting for a minority (median, 0.2%). The median ratio of ASC to squamous intraepithelial lesions and carcinomas (SIL+) was 1.4 and was lower than the 1996 median ratio of 2.0. Median reporting rates for squamous abnormalities for 2002 were noted to be significantly higher for liquid-based preparations than for conventional smears, while median ASC/SIL+ ratios were lower. Most laboratories offer human papillomavirus testing, but almost half (47%) of laboratories do not know the percentage of positive testing results in patients with ASC. Conclusions.—Most laboratories have implemented Bethesda 2001 terminology. New criteria and liquid-based methods have led to an increase in low-grade squamous intraepithelial lesion reporting rates and a decrease in ASC/ SIL+ ratios when compared with 1996 data. Liquid-based preparations have higher median squamous intraepithelial lesion rates and lower ASC/SIL+ ratios than conventional smears.

Abstract Context.—Although human papillomavirus (HPV) testing may aid in managing low-grade abnormality on screening cervical cytology, patient compliance with repeat testing programs requires consideration. Objectives.—To determine effectiveness and costs of repeated Papanicolaou (Pap) test and oncogenic HPV testing for detecting cervical intraepithelial neoplasia 2 or 3. Design.—We conducted a randomized controlled trial of combined Pap test and cervical HPV testing by Hybrid Capture 1 test compared with Pap test alone; tests were performed every 6 months for up to 2 years. The study end point was colposcopic examination performed on all women at 2 years, or earlier if an HPV test was positive or if a Pap test showed high-grade squamous intraepithelial lesion. Setting.—Sixty-six community family practices. Participants.—Two hundred fifty-seven women with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion on screening cervical cytology. Main Outcome Measures.—Detection of histologically confirmed cervical intraepithelial neoplasia 2 or 3, fully allocated costs, and loss to follow-up. Results.—Combined Pap test and HPV testing detected 11 (100%) of 11 cases of cervical intraepithelial neoplasia 2/3, whereas Pap test alone detected 7 (63.6%) of these 11 cases (P = .14); corresponding specificities were 39 (46.4%) of 84 and 45 (71.4%) of 63 (P = .005). The cost-effectiveness ratio was Can $4456 per additional case of high-grade cervical intraepithelial neoplasia. Sixty-nine (26.8%) of the 257 women (24.6% combined group vs 29.1% Pap test only group, P = .41) defaulted from testing or from colposcopy when referred with an abnormal result. Conclusions.—Combined testing was more costly but may detect more cases of cervical intraepithelial neoplasia 2/3 than Pap test alone. However, poor adherence limits usefulness of a management strategy that requires repeated follow-up.
