Feng T, Cheng B, Sun W, Yang Y. Outcome and associated factors of high-risk human papillomavirus infection without cervical lesions. BMC Womens Health 2023; 23:599. [PMID: 37957634 PMCID: PMC10644444 DOI: 10.1186/s12905-023-02764-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 11/04/2023] [Indexed: 11/15/2023] Open
Abstract
OBJECTIVE To study the outcome of human papillomavirus (HPV) infection in women with cervical pathology results of non-cervical intraepithelial neoplasia (CIN) or cervical cancer and positive high-risk HPV test, as well as analyze the associated risk factors affecting the outcome of infection. METHODS To investigate the outcome of high-risk (HR)-HPV infection in the female genital tract and analyze the associated risk factors affecting their outcome, a total of 196 women with positive HR-HPV test results and non-CIN or cervical cancer cervical pathology results were selected for follow-up at the Cervical Disease Clinic of the Obstetrics and Gynecology Hospital, Zhejiang University School of Medicine from January 2017 to March 2020. The follow-up interval was every 6 months, and both cervical cytology (TCT) and HR-HPV testing were performed at each follow-up visit. If the cervical cytology results were normal upon recheck and the HR-HPV test was negative, the woman was considered to be cleared of the HPV infection and was entered into the routine cervical screening population. When the repeat HR-HPV test remained positive after 6 months, the woman was defined as having a persistent HR-HPV infection. If HR-HPV persisted but the TCT results were normal, follow-up was continued. If HR-HPV persisted and the TCT results were abnormal, a colposcopy-guided biopsy was performed immediately. In this situation, if the histological results were still non-CIN or cervical cancer, the follow-up was continued. If the histological results confirmed the development of CIN or invasive cancer, then enter another study follow-up to further track its development and outcome, and the woman commenced the treatment process. The HPV infection clearance time was analyzed by the Kaplan-Meier method, and the comparison of the HPV clearance rate and infection clearance time between each of the different groups was performed using aχ2 test or Fisher's exact test, as appropriate. After the univariate analysis, several significant factors were included in the Cox model and independent risk factors were analyzed. RESULTS A total of 163 women were enrolled in this study. The median age was 40.0 years (22-67 years) and the median follow-up time was 11.5 months (6-31 months). The spontaneous clearance rate of HR-HPV infection was 51.5%, and the median time to viral clearance was 14.5 months. Age and the initial viral load were high risk factors affecting the spontaneous clearance of HR-HPV infection. The factors significantly associated with HPV clearance rate and time to HPV clearance consisted of menopause and full-term delivery (P < 0.05). CONCLUSIONS In women with normal or low-grade lesions on the cell smear, the spontaneous clearance rate of HR-HPV infection was 51.5% and the time to clearance was 14.5 months. Age and the initial viral load were independent associated factors affecting the spontaneous clearance of HR-HPV infection in the female genital tract. These findings suggest that non-young women or those with high viral loads have a higher rate of persistent HR-HPV infection. Thus, intensive screening should be recommended.

[PMID: 37889928 PMCID: PMC10637721 DOI: 10.1371/journal.pmed.1004304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 11/10/2023] [Accepted: 10/02/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Cervical screening programs use testing for human papillomavirus (HPV) genotypes. Different HPV types differ greatly in prevalence and oncogenicity. We estimated the impact of cervical screening and follow-up for each HPV type. METHODS AND FINDINGS For each type of HPV, we calculated the number of women needed to screen (NNS) and number of women needing follow-up (NNF) to detect or prevent one cervical cancer case, using the following individual level input data (i) screening and cancer data for all women aged 25 to 80 years, resident in Sweden during 2004 to 2011 (N = 3,568,938); (ii) HPV type-specific prevalences and screening histories among women with cervical cancer in Sweden in 2002 to 2011(N = 4,254); (iii) HPV 16/18/other HPV prevalences in the population-based HPV screening program (N = 656,607); and (iv) exact HPV genotyping in a population-based cohort (n = 12,527). Historical screening attendance was associated with a 72% reduction of cervical cancer incidence caused by HPV16 (71.6%, 95% confidence interval (CI) [69.1%, 73.9%]) and a 54% reduction of cancer caused by HPV18 (53.8%, 95% CI [40.6%, 63.1%]). One case of HPV16-caused cervical cancer could be prevented for every 5,527 women attending screening (number needed to screen, NNS). Prevention of one case of HPV16-caused cervical cancer required follow-up of 147 HPV16-positive women (number needed to follow-up, NNF). The NNS and NNF were up to 40 to 500 times higher for HPV types commonly screened for with lower oncogenic potential (HPV35,39,51,56,59,66,68). For women below 30 years of age, NNS and NNF for HPV16 were 4,747 and 289, respectively, but >220,000 and >16,000 for HPV35,39,51,56,59,66,68. All estimates were either age-standarized or age-stratified. The primary limitation of our study is that NNS is dependent on the HPV prevalence that can differ between populations and over time. However, it can readily be recalculated in other settings and monitored when HPV type-specific prevalence changes. Other limitations include that in some age groups, there was little data and extrapolations had to be made. Finally, there were very few cervical cancer cases associated with certain HPV types in young age group. CONCLUSIONS In this study, we observed that the impact of cervical cancer screening varies depending on the HPV type screened for. Estimating and monitoring the impact of screening by HPV type can facilitate the design of effective and efficient HPV-based cervical screening programs.

Assessment of the relationships between invasive endocervical adenocarcinoma and human papillomavirus infection and distribution characteristics in China: According to the new WHO classification criteria in 2020. Cancer Epidemiol 2023; 86:102442. [PMID: 37598648 DOI: 10.1016/j.canep.2023.102442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 07/18/2023] [Accepted: 08/07/2023] [Indexed: 08/22/2023]
Abstract
OBJECTIVE To assess the association between endocervical adenocarcinoma (ECA) and HPV (Human papillomavirus) infection, as well as the characteristics of ECA distribution in China. METHODS A total of 756 specimens were collected from seven geographic regions across China. All cases were histologically categorized according to the 2020 WHO classification of female genital tract cancers, and 496 cases were included. We performed the SPF10-DEIA-LiPA25 assay on all specimens' whole tissue sections using PCR (WTS-PCR) to detect HPV DNA and 141 WTS-PCR HPV-positive specimens were selected for the laser capture microdissection (LCM). RESULTS Four predominant prevalent histological categories of ECA in China were usual type (51.8%, 257), invasive stratified mucin-producing carcinoma (iSMILE) (11.5%, 57), mucinous NOS (not otherwise specid) (10.3%, 51), and gastric type (7.9%, 39). HPV positivity was 91.4% (235/257), 100.0% (57/57), and 90.2% (46/51) in usual type, iSMILE, and mucinous NOS by WTS-PCR detection, respectively (P < 0.001). LCM-PCR results showed a decreasing trend in HPV DNA positivity, and 21 (95.5%) patients with HPV-I were negative for HPV-DNA in glandular epithelial tissue. The most prevalent HPV genotypes in ECA were HPV16 (47.5%), 18 (40.8%), and 52 (6.5%). The average age of patients with HPVA was 44.9 years, while that of patients with HPV-I was 49.1 years, HPVA is more prevalent in younger females in China (P < 0.001). CONCLUSIONS In China, the predominant prevalent histological category of ECA is the usual type of adenocarcinoma, followed by iSMILE. Additionally, patients with HPVA tended to be younger than those with HPV-I.

Diagnostics (Basel) 2022; 12:diagnostics12081855. [PMID: 36010208 PMCID: PMC9406681 DOI: 10.3390/diagnostics12081855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 07/25/2022] [Accepted: 07/29/2022] [Indexed: 11/16/2022] Open
Abstract
Infection with high-risk (HR) Human Papillomavirus (HPV) is associated with the development of precancerous lesions or invasive carcinoma of the uterine cervix. Thus, the high viral load (VL) of HR-HPV DNA currently serves as a representative quantitative marker for cervical cancer. However, the clinical significance of low HPV DNA VL remains undetermined. This study aimed to evaluate the clinical association between the low HPV DNA VL and cytology/histologic diagnosis of cervical samples. We searched the electronic medical databases for the resultant analyses of HPV genotyping among patients who underwent treatment for any cervical lesion or who had undergone gynecological examinations with any positive HPV results according to the national cancer screening service between 2015 and 2016. HPV testing with genotyping and semi-quantitative VL measurement was conducted using an AnyplexTM II H28 Detection assay (H28 assay, Seegene, Seoul, Republic of Korea). The H28 assay is a multiplex semi-quantitative real-time PCR test using the tagging of oligonucleotide cleavage and extension (TOCE) technology. The VL was semi-quantified as high (3+; positive signal before 31 PCR cycles), intermediate (2+; positive between 31 and 39 PCR cycles), or low (1+; positive after 40 PCR cycles). Out of 5940 HPV VL analyses, 356 assays (5.99%) were reported as low VL (1+) of HPV DNA. Matched cytology diagnoses were mostly negative findings (n = 347, 97.5%), except for seven cases of atypical squamous cells of undetermined significance (1.9%) and two cases of atypical glandular cells (0.6%). During the follow-up periods, abnormal cytologic diagnoses were identified, including one case of high-grade squamous intraepithelial lesion (HSIL) and two low-grade squamous intraepithelial lesions (LSILs). The matched, confirmative histologic diagnosis of HSIL cytology was compatible with chronic inflammation, wherein the two LSILs had regular check-ups. None revealed clinically concerned outcomes associated with HPV-related squamous lesions. The cytology was most likely negative for malignancy when the VL of HPV DNA was low (1+). Additional strategic monitoring and management may thus be unnecessary.

Distribution of human papillomavirus genotypes by severity of cervical lesions in HPV screened positive women from the ESTAMPA study in Latin America. PLoS One 2022; 17:e0272205.

Abstract
The proportion of HPV16 and 18-associated cervical cancer (CC) appears rather constant worldwide (≥70%), but the relative importance of the other HR-HPV differs slightly by geographical region. Here, we studied the HPV genotype distribution of HPV positive Latin American (LA) women by histological grade, in a sub-cohort from the ESTAMPA study; we also explored the association of age-specific HPV genotypes in severe lesions. Cervical samples from 1,252 participants (854 ≤CIN1, 121 CIN2, 194 CIN3 and 83 CC) were genotyped by two PCRs-Reverse Blotting Hybridization strategies: i) Broad-Spectrum General Primers 5+/6+ and ii) PGMY9/11 PCRs. HPV16 was the most frequently found genotype in all histological grades, and increased with the severity of lesions from 14.5% in ≤ CIN1, 19.8% in CIN2, 51.5% in CIN3 to 65.1% in CC (p < 0.001). For the remaining HR-HPVs their frequency in CC did not increase when compared to less severe categories. The nonavalent vaccine HR-types ranked at the top in CC, the dominant ones being HPV16 and HPV45. HR-HPV single infection occurs, respectively, in 57.1% and 57.0% of ≤CIN1 and CIN2, increasing to 72.2% and 91.6% in CIN3 and CC (p<0.001). No association between age and HPV type was observed in CC, although the risk of HPV16 infection in CIN3 cases increased with age. Results confirm the relevance of HPV16 in the whole clinical spectrum, with a strong rise of its proportion in CIN3 and cancer. This information will be relevant in evaluating the impact of HPV vaccination, as a baseline against which to compare genotype changes in HPV type-specific distribution as vaccinated women participate in screening in LA region. Likewise, these data may help select the best HPV testing system for HPV-based efficient, affordable, and sustainable screening programmes.

Abstract
Cervical cancer (CC) is the third leading cause of death in women in Montenegro. Human papillomavirus (HPV) is the causative agent of CC however, HPV genotype distribution varies across regions. This study examined the distribution and impact of vaccine-related high-risk (HR)-HPVs on the development of cervical dysplasia in Montenegrin women. A total of 187 women who had a clinical indication for cervical biopsy were enrolled. Based on histopathological findings, women were classified into 2 groups, with and without dysplasia. HR-HPV was detected by real-time PCR. Twelve HR-HPV genotypes were detected in 40.6% of cervical samples. The 7 most prevalent HR-HPVs in order of decreasing frequency were HPV 16 (39.5%), 45 (23.7%), 31 (21.0%), 33 (17.1%), 18 (6.6%), 52 (6.6%), and 58 (6.6%), all of them are targeted by nonavalent vaccine. Vaccine-related HR-HPVs had a higher prevalence (92.1%) than the other HR-HPVs detected in HR-HPV-positive samples. Among HR-HPV-positive women, HPV 16 and 33 were more common in women with dysplasia than in those without dysplasia (HPV 16: 28.9 vs 7.2%; HPV 33: 11.8 vs 3.6%). HPV 16 was the most common HR-HPV genotype in cervical samples, followed by HPV 45, 31, 33, 18, 52, and 58. HPV 16 and 33 were shown to be associated with the development of cervical dysplasia. These results indicate that prophylactic nonavalent vaccine can potentially prevent approximately 90% of HR-HPV infections and 60% of cervical dysplasia cases in Montenegrin women.

Abstract
BACKGROUND Cervical cancer screening (CCS) by means of Pap smears has led to a decrease in cervical cancer incidence and mortality. In the absence of organized programmes, CCS is opportunistic in Belgium and Switzerland. This might result in a high level of CCS overuse, as screening practices do not conform to the recommended 3-yearly screening interval and the target age-ranges (Belgium: 25-64, Switzerland: 20-70). This study aimed to assess trends in CCS uptake and overuse in Belgium and Switzerland and their social determinants, in the light of reimbursement initiatives, which were implemented in both countries. METHODS Data from five waves of the Belgian Health Interview Survey (1997-2013) (N=11 141) and Swiss Health Interview Survey (1992-2012) (N=32 696) were used. We performed Poisson regressions to estimate adjusted prevalence ratios (APR), controlled for socio-economic and socio-demographic characteristics and health status. CCS overuse was operationalized as screening more than once every 3 years and screening above recommended age-range. RESULTS CCS uptake remained relatively stable over time, with a mean coverage of 70.9% in Belgium and 73.1% in Switzerland. Educational and income gradients were found in both countries. Concerning CCS overuse, women above screening-eligible age showed consistently high screening rates, but screening within the past year declined significantly in both countries, matching the temporal implementation of the reimbursement initiatives. CONCLUSIONS Although no increase in CCS coverage could be established, CCS has become more efficient in both countries as Pap smear overuse at the population level has declined after the implementation of reimbursement measures tackling CCS overuse.

Abstract
Aim In 9‐17‐year‐old Chinese girls, the AS04‐adjuvanted HPV‐16/18 vaccine (AS04‐HPV‐16/18) given as three‐dose schedule induced high antibody levels, which were noninferior 1 month after the third dose to those observed in 18‐25‐year‐old Chinese women in a large efficacy study. We assessed the persistence of antibodies 8‐9 years after vaccination in the same subjects. Methods This follow‐up phase III, open‐label study (NCT03355820) included subjects who had received three doses of AS04‐HPV‐16/18 in the initial trial (NCT00996125). Serum antibody concentrations were assessed by ELISA and compared to antibody persistence observed in 18‐25‐year‐old Chinese women 6 years after first vaccination in the efficacy study (NCT00779766). Results Out of the 227 enrolled subjects, 223 were included in the per‐protocol immunogenicity analysis. Mean interval from first AS04‐HPV‐16/18 dose to blood sampling was 101.4 months (8.5 years). For antibodies against HPV‐16 and ‐18, 8.5 years after first vaccine dose all subjects remained seropositive and antibody. Geometric mean concentrations (GMCs) were 1236.3 (95% confidence interval [CI]: 1121.8; 1362.4) and 535.6 (95% CI: 478.6; 599.4) ELISA Units/mL, respectively. These seropositivity rates and antibody GMCs were higher than those observed 6 years after first vaccination of 18‐25‐year‐old women. Conclusion Sustained anti‐HPV‐16 and ‐18 immune responses were observed 8‐9 years after AS04‐HPV‐16/18 vaccination of 9‐17 year‐old Chinese girls that were higher than the ones observed 6 years after first vaccination in Chinese adult women in whom AS04‐HPV‐16/18 efficacy against cervical intraepithelial neoplasia of grade ≥2 was demonstrated.

Abstract
OBJECTIVE National Spanish studies show that prevalence of cervical human papillomavirus (HPV) infection in the female population is increasingly frequent, with an overall estimate of 14% in women aged 18-65 years. The objective of this study is to know the prevalence and distribution of HPV types in the female population of the Canary Islands prior to the introduction of HPV vaccines and to investigate the associated clinical and sociodemographic factors. METHODS Based on the Primary Health Care database, a sample of adult women (aged 18-65 years) of Gran Canaria (GC) and Tenerife (TF) stratified into nine age groups was carried out between 2002 and 2007. Women were contacted by postal letter and telephone call and were visited in their primary care centre. A clinical-epidemiological survey was completed and cervical samples were taken for cytological study and HPV detection. HPV prevalence and its 95% CI were estimated, and multivariate analyses were performed using logistic regression to identify factors associated with the infection. RESULTS 6010 women participated in the study, 3847 from GC and 2163 from TF. The overall prevalence of HPV infection was 13.6% (CI 12.8%-14.5%) and 11.1% (CI 10.3%-11.9%) for high-risk types. The most frequent HPV type was 16 followed by types 51, 53, 31, 42 and 59. HPV types included in the nonavalent vaccine were detected in 54.1% of infected women. Factors associated with an increased risk of infection were: young ages (18-29 years), the number of sexual partners throughout life, not being married, being a smoker, and having had previous cervical lesions or genital warts. CONCLUSIONS It is confirmed that prevalence of HPV infection in the female population of the Canary Islands is high, but similar to that of Spain, HPV 16 being the most frequent genotype. The determinants of infection are consistent with those of other populations.

Is large loop excision of the transformation zone depth a risk factor for affected endocervical margins? J Obstet Gynaecol Res 2020; 46:2100-2107. [PMID: 32686274 DOI: 10.1111/jog.14392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 03/22/2020] [Accepted: 06/19/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The aim of the study was to determine if the depth of large loop excision of the transformation zone (LLETZ) is a risk factor for presenting affected endocervical margins. METHODS A cross-sectional retrospective study was performed on 353 patients that underwent LLETZ after presenting cervical biopsies with CIN grade 2 and grade 3 or persistent CIN grade 1 at Hospital Universitario Santa Lucía, Cartagena, Spain, from November 2011 to December 2016. Automatized measurement of the LLETZ depth was performed in microns and added to cervical canal extensions when these were performed. Other variables studied in positive endocervical margins were age (under or over 35 years), premenopause/postmenopause, number of affected quadrants, CIN grading, the presence of HPV 16 before LLETZ, parity (nulliparous vs multiparous) and the location where the LLETZ was performed (operating room vs consultation room). RESULTS Our multivariant analysis showed that LLETZ depth ≤ 10 mm did not increase the risk in affected endocervical margins (P = 0.366) and no statistically significant difference between the two groups (affected and nonaffected margins) was found. CIN grading and parity did prove a statistically significant association (P = 0.039 and P = 0.011, respectively). Age, menopause, number of affected quadrants, HPV 16 and the location did not show statistical association with positive endocervix margins. CONCLUSIONS LLETZ depth equal to or lower than 10 mm was not proven to be a risk factor to have affected endocervical margins after the treatment. Therefore, higher LLETZ depth would not be justified to ensure oncological results.

Low-grade squamous intraepithelial lesion on Papanicolaou test: follow-up rates and stratification of risk for high-grade squamous intraepithelial lesion. J Am Soc Cytopathol 2020; 9:258-265. [PMID: 32402830 DOI: 10.1016/j.jasc.2020.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 02/06/2020] [Accepted: 02/27/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Low-grade squamous intraepithelial lesion (LSIL) Papanicolaou test is associated with moderate risk of high-grade squamous intraepithelial lesion (HSIL) at colposcopic biopsy. High-risk human papillomavirus (hrHPV) cotesting risk stratifies patients with LSIL Papanicolaou test, with higher rates of HSIL for those hrHPV+. hrHPV genotyping is not considered in current LSIL management algorithms. MATERIALS AND METHODS We performed a 2-year retrospective review of LSIL Papanicolaou tests in patients 25 to 65 years old to assess rates of follow-up and HSIL at biopsy. Patient age, hrHPV cotest and genotype results, prior screening results, and follow-up testing for 3 years were recorded. RESULTS A total of 71.5% (376 of 526) of patients had at least 1 follow-up colposcopic biopsy; 18% had HSIL on follow-up, including 20% of hrHPV+ and 12% of hrHPV-. HSIL at biopsy was most common when HPV16/18 was present (32%) and when multiple subtypes were detected (46%) versus when non-16, non-18 hrHPV alone was present (16%) or hrHPV was negative (12%). Of those hrHPV-, 5 of 22 (23%) with a prior screening abnormality had HSIL versus 1 of 27 (4%) for those without prior abnormalities. Follow-up occurred more commonly for hrHPV+ cotests (82%) than hrHPV- cotests (54%). No differences in follow-up rate based on hrHPV genotyping was seen. CONCLUSIONS The highest HSIL rates were seen when HPV16/18 was present (32%). HSIL rates were similar for those hrHPV- (12%) and non-16, non-18 hrHPV+ (16%). Follow-up was more common for those hrHPV+, but genotype results did not impact follow-up rates. Past screening results may impact risk of HSIL for hrHPV- cases.

Abstract
Although high-risk (HR) human papilloma virus (HPV) infection is the primary causative factor for cervical squamous intraepithelial lesions and invasive cervical cancer, the epidemiology of potentially HR (pHR) and low-risk HPV still remains to be elucidated in HIV-infected women. In addition, the synergistic potential of the multiplicity of HPV infections harboured renders it difficult to model the impact of vaccines. This cross-sectional analysis of HIV-infected women explores the epidemiology of abnormal cytology, thereby profiling and pairing pHR/HR HPV genotypes. This cross-sectional analysis reports the findings of 593 HIV-infected women, who underwent a cytological examination and HPV genotyping. A logistic regression model was fitted to adjust for age and coinfection with pHR/HR HPV genotypes. In the 143 women with abnormal cytology, a multiple pHR/HR HPV genotype prevalence of 64.1% [95% confidence interval (CI): 44.6-57.6%] was observed. A combined prevalence of HPV 16 and HPV 18 of 29.6% (95% CI: 22.2-37.8%) was found. HPV 6 and HPV 66 were found in two cases of low-grade squamous intraepithelial lesions as stand-alone genotypes and HPV 53 in a high-grade squamous intraepithelial lesion case. Pairing involving HPV 31 with HPV 16 and HPV 58 was found in high-grade squamous intraepithelial lesion cases. Significant associations were observed between abnormal cytology, multiple HPV, HPV 39 and HPV 53 [adjusted odds ratio (aOR): 2.02; P=0.01; 95% CI: 1.2-3.5; aOR: 3.8; P=0.01; 95% CI: 1.4-10.7; and aOR: 0.5; P=0.03; 95% CI: 0.2-0.9, respectively]. Coinfection with pHR/HR HPV genotypes HPV 39 and 53 was significantly associated with abnormal cytology. Research into the imputed role of HPV 31 in pairings, low-risk and pHR HPV genotypes in HIV-infected women is warranted.

Concordance of HPV load and HPV mRNA for 16 carcinogenic/possibly carcinogenic HPV types in paired smear/tissue cervical cancer specimens. Arch Virol 2017; 162:3313-3327.

Abstract
HPV types with high viral load are associated with cervical abnormalities. However, viral load measurements and concordance of HPV loads and viral mRNA have not been demonstrated for all high-risk/possibly high-risk (HR-/pHR-)HPV types in cervical cancer (CxCa). Especially, the biological role of co-infecting HR-/pHR-HPV types with low viral load has not been thoroughly investigated. Using BSGP5+/6+-PCR/MPG genotyping, we analyzed viral loads for all currently defined 51 mucosal HPV types in 74 cervical smears from patients with CxCa and compared this data with HPV DNA and mRNA status in these patients' corresponding CxCa tissues. All cervical smear/tissue pairs were HPV DNA+. Overall HPV type agreement within pairs was 99% (complete agreement in 50%, partial agreement in 49%, and complete disagreement in 1% of cases). The proportion of multiple HPV types was significantly higher in smears compared to tissues (p<0.0001). High load HPV infections (>1 copy/cell) were found in 88% of HPV DNA+ smears, and were significantly associated with the presence of respective HPV DNA (kappa=0.685, CI: 0.567-0.803), and HPV mRNA (kappa=0.693, CI: 0.566-0.820) in CxCa tissues. In total, 93% (67/72) of high load HR-/pHR-HPV infections identified in smears were also present in corresponding CxCa tissues, and 93% (62/67) of these were HPV mRNA+. On the other hand, 78% (42/54) of low load HR-/pHR-HPV infections identified in smears were not detectable in tissues, including 11 out of 15 low load HPV16 infections. This data demonstrates that the presence of high HPV loads in CxCa smears predicts biologically active HR-/pHR-HPV types in tumor tissues.

Abstract
The main etiological factor of precancerous lesion and invasive cervical cancer are oncogenic human papillomaviruses types (HPVs). The objective of this study was to establish the distribution of the most common HPVs in different cervical lesions and cancer prior to the implementation of organized population-based cervical screening and HPV vaccination in Croatia. In this study, 4,432 cervical specimens, collected through a 16-year period, were tested for the presence of HPV-DNA by polymerase chain reaction (PCR) with three sets of broad-spectrum primers and type-specific primers for most common low-risk (LR) types (HPV-6, 11) and the most common high-risk (HR) types (HPV-16, 18, 31, 33, 45, 52, 58). Additional 35 archival formalin-fixed, paraffin embedded tissue of cervical cancer specimens were analyzed using LiPA25 assay. The highest age-specific HPV-prevalence was in the group 18-24 years, which decreased continuously with age (P<0.0001) regardless of the cytological diagnosis. The prevalence of HR-HPV types significantly increased (P<0.0001) with the severity of cervical lesions. HPV-16 was the most common type found with a prevalence (with or without another HPV-type) of 6.9% in normal cytology, 15.5% in atypical squamous cells of undetermined significance, 14.4% in low-grade squamous intraepithelial lesions, 33.3% in high-grade squamous intraepithelial lesions, and 60.9% in cervical cancer specimens (P<0.0001). This study provides comprehensive and extensive data on the distribution of the most common HPV types among Croatian women, which will enable to predict and to monitor the impact of HPV-vaccination and to design effective screening strategies in Croatia.

Abstract
INTRODUCTION Ano-Genital Warts (AGW) like other Sexually Transmitted Diseases (STD) is associated with Human Immunodeficiency Virus (HIV) infection. This study of AGW was done in HIV positive and HIV negative patients. AIM To study the risk factors and clinical presentations of ano-genital warts in HIV positive and negative patients. MATERIALS AND METHODS A comparative, cross-sectional, descriptive study of 25 HIV positive and 25 HIV negative (n=50) AGW patients between 15-60 years of both sex was conducted in Dr. D. Y. Patil Hospital and Research Centre from July 2014 to July 2016. RESULTS Significant association of HIV positivity (p<0.05) was observed between age group of 15-30 years and HIV negative status (p<0.05) in age group of 31-45 years. HIV positive status significantly higher in patients with self-admitted multiple sexual partners (p<0.01), homosexuality (p<0.05) and presentation with anal warts (p<0.01). HIV negative status correlated significantly with single sexual partner admission (p<0.01) and hetero-sexuality (p<0.05). Gender did not show significant association with number of sexual partners or HIV positivity. Extra-genital or only genital warts had no association with HIV status. Co-STDs though more in number in ser-positive group, did not show any significant association with HIV positivity (p>0.05). No patient presented with changes of malignancy. Four were adolescents below 19 years. Two patients had atypical presentations of giant condylomata i.e., Buschke-Lowenstein Tumour (BLT). CONCLUSION HIV positivity was significantly associated with the risk factors of age below 30 years, homo sexuality and multiple sexual partners. Anal warts were significantly common in HIV positive patients. Four adolescents with AGW underline the need for high risk behaviour counselling. No patient had malignant ano-genital warts. Follow up of these patients with Human Papilloma Virus (HPV) sub-typing is necessary.

Depuydt CE, Thys S, Beert J, Jonckheere J, Salembier G, Bogers JJ. Linear viral load increase of a single HPV-type in women with multiple HPV infections predicts progression to cervical cancer. Int J Cancer 2016; 139:2021-32. [PMID: 27339821 DOI: 10.1002/ijc.30238] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 05/01/2016] [Accepted: 06/06/2016] [Indexed: 01/21/2023]
Abstract
Persistent high-risk human papillomavirus (HPV) infection is strongly associated with development of high-grade cervical intraepithelial neoplasia or cancer (CIN3+). In single type infections, serial type-specific viral-load measurements predict the natural history of the infection. In infections with multiple HPV-types, the individual type-specific viral-load profile could distinguish progressing HPV-infections from regressing infections. A case-cohort natural history study was established using samples from untreated women with multiple HPV-infections who developed CIN3+ (n = 57) or cleared infections (n = 88). Enriched cell pellet from liquid based cytology samples were subjected to a clinically validated real-time qPCR-assay (18 HPV-types). Using serial type-specific viral-load measurements (≥3) we calculated HPV-specific slopes and coefficient of determination (R(2) ) by linear regression. For each woman slopes and R(2) were used to calculate which HPV-induced processes were ongoing (progression, regression, serial transient, transient). In transient infections with multiple HPV-types, each single HPV-type generated similar increasing (0.27copies/cell/day) and decreasing (-0.27copies/cell/day) viral-load slopes. In CIN3+, at least one of the HPV-types had a clonal progressive course (R(2) ≥ 0.85; 0.0025copies/cell/day). In selected CIN3+ cases (n = 6), immunostaining detecting type-specific HPV 16, 31, 33, 58 and 67 RNA showed an even staining in clonal populations (CIN3+), whereas in transient virion-producing infections the RNA-staining was less in the basal layer compared to the upper layer where cells were ready to desquamate and release newly-formed virions. RNA-hybridization patterns matched the calculated ongoing processes measured by R(2) and slope in serial type-specific viral-load measurements preceding the biopsy. In women with multiple HPV-types, serial type-specific viral-load measurements predict the natural history of the different HPV-types and elucidates HPV-genotype attribution.

Prevalence of high-risk human papillomavirus and abnormal pap smears in female sex workers compared to the general population in Antwerp, Belgium. BMC Public Health 2016; 16:477. [PMID: 27266509 PMCID: PMC4897854 DOI: 10.1186/s12889-016-3099-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2015] [Accepted: 05/13/2016] [Indexed: 11/30/2022] Open
Abstract
Background Although female sex workers (FSWs) are a well-known high-risk group for Human Papillomavirus (HPV) infections, few tailored intervention programmes for HPV have been established worldwide. The lack of reliable data on the prevalence of HPV and related cervical lesions hampers the establishment of evidence-based intervention programmes. The objectives of this study were to describe the prevalence of high-risk Human Papillomavirus (hrHPV) infections and abnormal pap smears in FSWs compared to a control group in Antwerp, Belgium. Methods HPV genotyping and cytology data were analysed from routine Pap smear tests that were collected from both FSWs and the general population (1334 samples for each group) between June 2006 and June 2010. Within the laboratory database, all FSWs were matched 1:1 for age and testing date to determine the ORs of hrHPV genotypes, DNA and cytology outcome. Results The prevalence of hrHPV DNA in FSWs was 41.7 % compared to 19.8 % in the age-matched controls with an overall OR of 2.8 (95 % CI: 2.3–3.4). Significant differences were observed in all age groups, and the most significant differences were observed in the cohort under 21 years of age (prevalence of 64.4 % in FSWs versus 14.8 % in controls; OR 10.3 (95 % CI: 5.0–21.2). Significantly more cervical lesions were observed in FSWs, particularly in the 17- to 21-year old age group (OR for LSIL or HSIL: 10.3 (95 % CI: 3.2–33.8). In both groups, HPV 16 was the most prevalent at 12.1 and 6.6 % in the FSW and control groups, respectively. HPV 18 was the 8th and 7th most frequent genotype at 5.0 and 2.5 % in the FSW and control groups, respectively. Conclusions FSWs have a significantly higher prevalence of hrHPV and more abnormal Pap smears than does the general population in Antwerp, Belgium. The hrHPV prevalence in FSWs is similar to that reported in the literature. The need for tailored intervention programmes should be investigated further.

High-risk human papillomavirus genotypes distribution in a cohort of HIV-positive women living in Europe: epidemiological implication for vaccination against human papillomavirus. AIDS 2016; 30:425-33.

Abstract
BACKGROUND Worldwide, human papillomavirus (HPV) 16 and 18 represents 70% of high-risk (HR) HPV found in cervical cancer. However HIV-positive women are more frequently infected by HRHPV other than HPV 16 or 18 (OHR). We aimed to analyse the HRHPV genotype distribution in a cohort of HIV-positive women and to estimate the potential protection offered by the different HPV vaccines. METHODS HRHPV genotypes by PCR and cytology were assessed in cervical samples from 508 HIV-positive women prospectively followed in Brussels. RESULTS Women characteristics were as follows: African origin (84%), median age 42 years, median CD4 T 555/μl, 89% under combined antiretroviral therapy and 73% with HIVRNA less than 20 copies/ml. HRHPV prevalence was 23% (116/508): 38% had abnormal cytology, 76% carried OHR without HPV 16 or 18 and 11% had concomitant infection by OHR and HPV 16 or 18. The most frequent HRHPV were HPV52 (19.8%), HPV18 (14.6%), HPV31/35/51/58 (12.1% each), HPV56 (9.9%) and HPV16 (9.5%). Less than 30% of women had their HRHPV genotypes included in the bivalent or quadrivalent vaccines against HRHPV 16 and 18; however, 79% had their HRHPV covered by the ninevalent vaccine against HRHPV 16/18/31/33/45/52/58. CONCLUSION The HRHPV genotypes distribution found in these women living in Europe with a successfully treated HIV is similar to the one found in Central Africa with HRHPV other than HPV16 or 18 retrieved in 87%. In this population, the bivalent or quadrivalent vaccines could offer protection in only 30% of women; however this protection could be extended up to 80% with the ninevalent vaccine.

Abstract
BACKGROUND Northern Thailand is a region with a high cervical cancer incidence. Combined high-risk HPV (hrHPV) DNA testing and cytology (co-testing) has increasingly gained acceptance for cervical cancer screening. However, to our knowledge, data from a population-based screening using co-testing have not been available in this region. This study therefore aimed to evaluate the performance of cytology and hrHPV test in women in northern Thailand. MATERIALS AND METHODS Cervical samples were collected for hybrid capture 2 (HC2) testing and liquid-based cytology from women aged 30 to 60 years who were residents in 3 prefectures of Chiang Mai in northern Thailand between May and September 2011. Women with positive cytology were referred to colposcopy, while women with positive for HC2 only were followed for 2 years. RESULTS Of 2,752 women included in this study, 3.0% were positive in both tests, 4.1% for HC2 only, and 1.3% had positive cytology only. At baseline screening, positive HC2 was observed in 70.6% among cytology-positive women compared with 4.3% among cytology-negative women. The prevalence of positive HC2 or cytology peaked in the age group 35-39 years and was lowest in the age group 55-60 years. High-grade squamous intraepithelial lesion or worse lesions (HSIL+) were histologically detected in 23.5% of women with positive baseline cytology and in 9.8% of women with positive baseline HC2 only on follow-up. All women with histologic HSIL+ had positive baseline HC2. CONCLUSIONS The hrHPV test is superior to cytology in the early detection of high-grade cervical epithelial lesions. In this study, the prevalence of histologic HSIL+ on follow-up of women with positive hrHPV test was rather high, and these women should be kept under careful surveillance. In northern Thailand, hrHPV testing has a potential to be used as a primary screening test for cervical cancer with cytology applied as a triage test.

Abstract
OBJECTIVE Human papillomavirus virus (HPV) is the major causative factor for cervical cancer, and sex workers are at high risk for HPV infection. In this study, we aimed to estimate the prevalence and risk factors of HPV infection among female sex workers (FSWs). MATERIALS AND METHODS The study included 239 brothel-based FSWs who work in Izmir, Turkey. A self-administered questionnaire for risk factors was completed, and cervical brush samples were taken for HPV detection and typing. HPV detection and typing were performed by multiplex polymerase chain reaction (PCR) and reverse hybridization methods. The risk factors related to HPV infection were determined by multivariate analysis. RESULTS The prevalence of HPV among FSWs was 20.1%. HPV18 was the most common type (40%), followed by HPV16 (17%) and HPV50 (15%). Logistic regression analysis revealed that being less than 30 years of age, having a high frequency of sexual contacts, smoking, and lack of condom use were significantly associated with HPV infection. CONCLUSION FSWs have a high prevalence of HPV infection and are at increased risk for cervical cancer. As they are a priority group for active follow-up, national strategies for reducing HPV among FSWs and regular cervical cancer screening programs should be implemented for this population.

Abstract
In 2012, the International Agency for Research on Cancer concluded that there was consistent and sufficient epidemiological, experimental and mechanistic evidence of carcinogenicity to humans for 12 HPV types (HPV16, HPV18, HPV31, HPV33, HPV35, HPV39, HPV45, HPV51, HPV52, HPV56, HPV58 and HPV59) for cervical cancer. Therefore, these types were considered as 1A carcinogens. They all belong to the family of the α-Papillomaviridae, in particular to the species α5 (HPV51), α6 (HPV56), α7 (HPV18, HPV39, HPV45, HPV59) and α9 (HPV16, HPV31, HPV33, HPV35, HPV52, HPV58). Less evidence is available for a thirteenth type (HPV68, α7), which is classified as a 2A carcinogen (probably carcinogenic). Moreover, seven other phylogenetically related types (HPV26, HPV53, HPV66, HPV67, HPV68, HPV70 and HPV73) were identified as single HPV infections in certain rare cases of cervical cancer and were considered possibly carcinogenic (2B carcinogens). Recently, Halec et al [7] demonstrated that the molecular signature of HPV-induced carcinogenesis (presence of type-specific spliced E6*| mRNA; increased expression of p16; and decreased expression of cyclin D1, p53 and Rb) was similar in cervical cancers containing single infections with one of the eight afore-mentioned 2A or 2B carcinogens to those in cancers with single infections with group 1 carcinogens. Ninety six percent of cervical cancers are attributable to one of the 13 most common HPV types (groups 1 and 2A). Including the additional seven HPV types (group 2B) added 2.6%, to reach a total of 98.7% of all HPV-positive cervical cancers. From recently updated meta-analyses, it was shown that HPV68, HPV26, HPV66, HPV67, HPV73 and HPV82 were significantly more common in cancer cases than in women with normal cervical cytology, suggesting that for these HPV types, an upgrading of the carcinogen classification could be considered. However, there is no need to include them in HPV screening tests or vaccines, given their rarity in cervical cancers.

Abstract
Human papillomavirus (HPV) infections are causally related to cervical cancer and a range of other diseases, both in adults and in minors. Information on the frequency of genital HPV infections in adolescents is sparse. The aim of this study was to gain insight into the genotype-specific distribution of HPV genotypes in patients younger than 18 years of age. This observational retrospective study included 4807 samples of patients presenting for opportunistic screening in Belgium between June 2006 and January 2012. For statistical analysis, only the first visits of patients were withheld, reducing the sample to 4180. Samples were collected in liquid-based cytology medium and analyzed using a series of genotype-specific real-time PCR reactions. Cytology was read with previous knowledge of HPV infection and scored using the Bethesda classification. The mean age was 16.9 years. Most youngsters had no complaints (88.4%), were using hormonal contraception (79.5%), and clinical examination did not show any abnormalities (96.0%). The overall HPV frequency was 15.7%, with the most frequently found types being HPV16 (16.7%), HPV51 (14.6%), HPV66 (10.4%), HPV31 (9.9%), and HPV39 (9.1%). More than one-third (39.0%) of the infected girls harbored an infection with at least two HPV genotypes. Cytological abnormalities were found in 8.2% of samples. L-SIL (4.2%) was most frequently observed, followed by ASC-US (3.6%), HSIL (0.3%), and ASC-H (0.1%). The severity of lesions worsened with increasing age. Our findings indicate that an aberrant HPV genotype profile can be found in adolescent girls; moreover, this group shows a high rate of cervical abnormalities.

Abstract
BACKGROUND Large-scale data on type-specific HPV prevalences and disease burden are needed to monitor the impact of HPV vaccination and to plan for HPV-based cervical screening. METHODS 33 043 women (aged 25-65) were screened for HPV by a Hybrid Capture 2 (HC2) in a population-based programme. HPV-positive women (n=2574) were triaged by cytology and HPV genotyped using PCR-Luminex. Type-specific prevalence of HPV infection and its correlation to findings in cytology triage and histology as well as Population Attributable Fractions for a referral to colposcopy and findings in histology were calculated. RESULTS Among HC2-positive women, 61.5% had normal, 23.1% had ASC-US and 15.5% had LSIL or more severe (LSIL+) results in cytology. Out of HC2-positive samples, 57% contained the 13 Group 1/2A HPV types, which were targeted by the HC2, 15% contained Group 2B types, 8.5% Group 3 types and 30% were found to be negative in HPV genotyping. The proportion of samples positive for HPV by the HC2, but negative in HPV genotyping increased with age and decreased with increasing cytological abnormality. The most frequent types were HPV 16 (0.9% of screened women and 12.1% of the HC2-positive women), HPV 31 (0.7% and 8.9%, respectively) and HPV 52 (0.5% and 6.3%, respectively). The prevalence of Group 1/2A HPV types increased with increasing CIN grade and attributed 78.3% (95% CI 53.4-89.9) of the CIN 3+ lesions, while HPV 16 attributed 55.8% (40.0-67.5) of them. CONCLUSION The type-specific prevalence of HPV were slightly lower than the average in international meta-analyses. Genotyping for HPV 16 better identified women with CIN 3+ than cytology triage at the threshold of LSIL+. The high proportion of women that were HC2-positive but HPV-negative in genotyping suggests that HPV genotyping may be useful also for validation of results in HPV screening. The large-scale HPV genotyping data were found to be directly useful for planning further preventive efforts for cervical cancer.

Abstract
Background Knowledge of prevalence rates and distribution of human papillomavirus (HPV) genotypes prior high HPV vaccine coverage is necessary to assess its expected impact on HPV ecology and on cervical lesions and cancers. Methods Residual specimens of cervical cytology (N = 6,538) were obtained from 16 sites participating in organised cervical cancer screening pilot programs throughout France, anonymised and tested for HPV DNA using the PapilloCheck® genotyping test. Samples were stratified according to age of women and cytological grades. Results The age-standardised prevalence rates of HPV 16 and/or 18 (with or without other high-risk types) was 47.2% (95% Confidence Interval, CI: 42.4–52.1) in high-grade squamous intraepithelial lesions (HSILs), 20.2% in low-grade SIL (95% CI: 16.7–23.7) and 3.9% (95% CI: 2.8–5.1) in normal cytology. Overall HR HPV were detected in 13.7% (95%I CI: 11.7–15.6) of normal cytology. In women below 30 years of age, 64% of HSILs were associated with HPV16 and/or 18. In our study population, HPV16 was the most commonly detected type in all cervical grades with prevalence rates ranking from 3.0% in normal cytology to 50.9% in HSILs. HPV16 was also detected in 54% (27/50) of invasive cervical cancers including 5 adenocarcinomas. Conclusion HPV16 was strongly associated with cervical precancer and cancer. The high prevalence rates of HPV16/18 infection among women below 30 years of age with HSILs suggests that the impact of vaccination would be primarily observed among young women.

Abstract
BACKGROUND High-risk human papilloma virus (HR-HPV) infection is associated with the development of cervical cancer. HPV vaccination reduces the risk of developing malignant lesions and is expected to change the dynamics of HPV transmission. Data from non-vaccinated women may provide an important benchmark to allow the impact of HPV vaccination programs to be assessed.This study was designed to prospectively determine the changing dynamics of HR-HPV infection and associated genital diseases in young women, most of whom were non-vaccinated. METHODS Data from a population-based cohort study, comprising women of two predefined birth cohorts (women born in 1983/84 or 1988/89), were analyzed between 19 October 2009 and 31 December 2010 to determine risk factors for high-risk HPV infection and the association between specific HR-HPV types and atypical Pap smear test results. HPV status was determined by Hybrid Capture 2 (HC2) assay and genotyping. RESULTS The prevalence of HR-HPV was 22.8% in the 1983/84 cohort (150/659) and 23.7% in the 1988/99 cohort (142/599). Only the number of sexual partners was a significant risk factor for HPV infection (odds ratios 22.687 and 6.124 for more than five versus one partner 84 cohort,/84 and 1988/89 cohorts, respectively) in multivariate analysis. HPV16 positive-women were significantly more likely to have abnormal Pap smears of any degree than HPV16-negative women (22.0% versus 3.61%, p < 0.0001 for the 1983/84 cohort and 9.09% versus 2.52%, p = 0.0482 for the 1988/89 cohort). CIN3 was diagnosed in six women 84 cohort,/84 cohort and two in the 1988/89 cohort. All women with CIN3 tested positive for HC2-HR and all six CIN3 cases 84 cohort,/84 cohort tested positive for HPV16. In the 1988/89 cohort, the rate of HPV16 infection was significantly lower in vaccinated than non-vaccinated women (1.59% versus 8.88%; p = 0.003). CONCLUSIONS HR-HPV infection was highly prevalent in both cohorts and associated with an increased risk of abnormal Pap smears and biopsy proven CIN2+. HPV16 infection was associated with a high risk of clinically relevant lesions. HPV vaccination significantly decreased the risk of HPV16 infection.

Abstract
Introduction Cervical infection with high-risk human papillomavirus (HRHPV) induces cervical cancer and is present in 14% of women in Europe. We assessed the prevalence and incidence of cervical HRHPV in a cohort of HIV-positive women living in Belgium. Methods Prospective observational program of screening and follow up of HRHPV cervical infection performed by Hybrid Capture in 825 HIV-positive women between 2002 and 2011. Women without normal cervix at baseline were excluded. Results The final analysis included 652 women: median age 38 years, African origin (81%), median HIV follow-up (66 months), median CD4 count (426 cells/μL) and 79% on antiretroviral therapy (cART). At baseline, HRHPV prevalence was 43% and decreased significantly as both age and CD4 cell count increased: highest prevalence (100%) in women <30 years and <200 CD4/μL and lowest (19%) in women >40 years and >500 CD4/μL (p<0.0001, multivariate analysis). The relative risk (RR) to carry HRHPV at baseline decreases proportionally by 11% for each 5 years-age increase and by 11% for each 100 CD4 cells/μL rise (RR=0.89, 95% CI: 0.85-0.93; p<0.0001, Poisson regression for both). During follow-up, incidence rate of HRHPV was 13.4 per 100 women-years. Conclusions We found a high HRHPV prevalence of 43% and an incidence rate of 13 per 100 women-years in this cohort of HIV-positive women living in Europe and on cART. Women under 40 years-age had the highest prevalence even with CD4 count >350 cells/μL. The magnitude of HRHPV epidemiology should prompt to evaluate the clinical efficacy of vaccines against HPV in HIV-infected women.

Abstract
BACKGROUND Infections with high-risk human papillomaviruses (Hr-HPV) can cause malignant transformation of the human cervical epithelium. HPV DNA tests generally are very sensitive to detect cervical neoplastic lesions but also identify transient HPV infections. As a consequence, the specificity and positive predictive value are low. METHODS We analyzed viral load of Hr- and possibly Hr-HPV types more than seven orders of magnitude (on a log10 scale) in 999 consecutive BD-SurePath liquid-based cervical cytology samples from routine cervical screening enriched with atypical squamous cells of undetermined significance (n = 100), low-grade squamous intraepithelial lesions (LSIL; n = 100), and high-grade squamous intraepithelial lesions (HSIL; n = 97) using type-specific multiplex quantitative real-time PCR and the BSGP5+/6+-PCR/MPG assay. In the 36-month follow-up, 79 histologically verified CIN2+ and 797 double-negative cytology cases were identified. RESULTS Viral loads in LSIL and HSIL were significantly increased compared with no intraepithelial lesion or malignancy in both the quantitative PCR (qPCR) and BSGP5+/6+-PCR/MPG assay (P < 0.0001). The mean viral loads in LSIL and HSIL were not significantly different. Using a newly determined high viral load cut off for 14 Hr-HPV types, the sensitivity for prevalent CIN3+ remained at 100% for both assays compared with the minimal detection threshold. The specificity (corresponding to double-negative cytology at subsequent screening episodes) increased substantially (qPCR, from 91.1% to 95.7%; BSGP5+/6+-PCR/MPG, from 79.8% to 96.2%). CONCLUSIONS Compared with DNA positivity alone, high Hr-HPV viral loads could reduce the amount of false positive results detected by the BSGP5+/6+-PCR/MPG and qPCR by 81.4% and 52.1%, respectively. IMPACT Quantitative type-specific HPV DNA assays show high flexibility in defining thresholds that allow optimizing clinical accuracy for cervical cancer precursors.

Abstract
Of the 120 known human papillomaviruses (HPV), 51 HPV types infect the genital mucosa. Very little is known about the prevalence and viral load of the majority of these low-risk (Lr-) HPV types in screening populations. We determined the prevalence of 51 HPV types and three subtypes in 999 consecutive BD-SurePath™ liquid-based cervical cytology samples collected during routine gynecological health checks from Belgian women. This series of screening samples was enriched with ASC-US (n = 100), low-grade squamous intraepithelial lesion LSIL (n = 100) and high-grade squamous intraepithelial lesion (HSIL) (n = 97) and analyzed by BSGP5+/6+-PCR/MPG assay for 51 HPV types and three subtypes. In consecutive screening samples, any of the 54 genital HPV (sub)types was found in 37.1%; Hr-HPV types were detected more frequently (26.8%) than the 31 Lr-HPV types (16.4%) and the six possibly high-risk types (6.6%). High viral load infections were present in 17.0% of the screening population. Among the women with cytological abnormalities, the prevalence of high viral loads of Hr-HPV types increased from negative for intraepithelial lesion or malignancy (NIL/M) over ASC-US, LSIL to HSIL (5.3, 47.1, 84.2 and 91.8%, respectively). The prevalence of possibly Hr and Lr-HPV types increased from NIL/M to LSIL but declined to HSIL. From NIL/M to HSIL, Hr-HPV infections showed an increasing frequency of high viral loads compared to total DNA positivity, but the increase between LSIL and HSIL was small. Type-specific analyses revealed substantial differences between individual HPV types in these groups. Our study provides quantitative data for the whole spectrum of genital HPV in a Belgian screening population and in a representative set of women with cervical abnormalities.

Abstract
To be acceptable for use in cervical cancer screening, a new assay that detects DNA of high-risk human papillomavirus (hrHPV) types must demonstrate high reproducibility and performance not inferior to that of a clinically validated HPV test. In the present study, a real-time quantitative PCR (qPCR) assay targeting the E6 and E7 genes of hrHPV was compared with Hybrid Capture 2 (hc2) in a Belgian cervical cancer screening setting. In women >30 years old, the sensitivity and specificity for intraepithelial neoplasias of grade 2 or worse (93 cases of cervical intraepithelial neoplasias of grade 2 or worse (CIN2+) and 1,207 cases of no CIN or CIN1) were 93.6% and 95.6%, respectively, and those of hc2 were 83.9% and 94.5%, respectively {relative sensitivity of qPCR/hc2 = 1.12 [95% confidence interval (CI), 1.01 to 1.23]; relative specificity = 1.01 [95% CI, 0.99 to 1.03]}. A score test showed that the sensitivity (P < 0.0001) and specificity (P < 0.0001) of the qPCR assay were not inferior to those of hc2 at the required thresholds of 90% and 98%, respectively. The overall agreement of hrHPV positivity between the two runs of the qPCR tests was 98.7% (95% CI, 97.5 to 99.4%), with a kappa value of 0.96 (95% CI, 0.83 to 1.00). The qPCR assay used in this study can be considered a reliable HPV assay that fulfills the clinical validation criteria defined for use in cervical cancer screening.

Abstract
OBJECTIVES/HYPOTHESIS The prevalence of human papillomavirus (HPV) in a clinical series of 162 patients with oral squamous cell carcinoma (OSCC) was studied. Furthermore, we analyzed the correlation between the immunohistochemical expression of p16, p53, epidermal growth factor receptor (EGFR), and HPV status to predict survival in OSCC patients. STUDY DESIGN Retrospective study. METHODS Paraffin-embedded samples from OSCC patients (n = 162) were evaluated for the presence of HPV DNA using both GP5+/GP6+ consensus polymerase chain reaction (PCR) and type-specific E6/E7 PCR to detect HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 67, and 68. Immunohistochemical staining for p16, p53, and EGFR was also performed. RESULTS The type-specific E6/E7 PCR demonstrated that 65 of the 147 OSCC patients (44%) presented with high-risk (hr) HPV types and that 38 of the 147 OSCC patients (26%) presented with low-risk (lr) HPV types. Comparable p53 and EGFR expression levels were observed in the hr HPV+ group (41.5% p53+, 92% EGFR+) and the lr HPV+ group (57% p53+, 92% EGFR+). Conversely, a slight increase in the proportion of p16+ tumors was observed in the hr HPV+ group (65%) compared with the lr HPV+ group (44%). In regard to patient outcome, the presence of HPV was correlated with a worse prognosis (P = .007). CONCLUSIONS A high prevalence of hr and lr HPV infections was detected in the OSCC patients included in the study. Moreover, hr HPV positivity was correlated with a decreased 5-year disease-free survival rate compared with HPV- and lr HPV+.

Abstract
OBJECTIVE The objective of the study was to investigate whether knowledge of human papillomavirus (HPV) deoxyribonucleic acid test results increases sensitivity of guided cytology screening for the detection of cervical intraepithelial neoplasia (CIN)-2 or higher-grade cervical lesions. STUDY DESIGN This was a prospective colposcopy-controlled study of 2905 BD SurePath samples to identify cases with CIN2+ within a 24 month follow-up period. Sensitivity and specificity to detect CIN2+ was evaluated, comparing guided cytology screening with and without prior knowledge of HPV status. RESULTS Prior knowledge of HPV status resulted in significantly higher detection rate of CIN2+ compared with screening blinded to HPV status (P = .005) with limited loss of specificity (P = .026). Gain in sensitivity is higher in older women (43.8%, P = .008) vs in younger women (10.2%, P = .317), whereas loss of specificity is more pronounced in younger women (P < .001) vs older women (P = .729). CONCLUSION Guided cytological screening performed with prior knowledge of HPV status results in an improved detection of CIN2 or higher-grade lesions.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of human papillomavirus (HPV) in 80 tumor-free tonsils from healthy children and adults using a sensitive E6/E7 type-specific polymerase chain reaction (PCR). STUDY DESIGN Cross-sectional study. SETTING Ear, nose, and throat department, university hospital. SUBJECTS AND METHODS Paraffin-embedded tissues from tumor-free tonsils (TFTs) were evaluated for HPV DNA using GP5+/6+ consensus PCR and subsequent genotyping using E6/E7 type-specific PCR for HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, and 68. The immunohistochemical expression of p16 and p53 was also assessed. RESULTS In 80 TFTs, the authors identified 10 (12.5%) that tested positive for the following high-risk HPV types: HPV 16 (8 cases), 18 (1 case), and 31 (1 case). Twelve patients (15%) tested positive for HPV infection using the GP5+/GP6+ consensus primers but were negative using quantitative PCR. These patients were considered infected with low-risk HPV types. Fifty-eight TFTs (72.5%) tested negative for both GP5+/GP6+ and type-specific HPV PCR analysis (HPV negative). Among patients infected with HPV, the authors observed a slight increase in frequency with age. CONCLUSION In TFTs, oncogenic and nononcogenic HPVs were present at a relatively high frequency in children and adults. The presence of high-risk HPV DNA in young children supports the horizontal transmission hypothesis and argues in favor of HPV vaccination at birth.

Abstract
The present study estimates the prevalence and risk factors of human papillomavirus (HPV) infection among female sex workers (FSWs) in Bulgaria. HPV DNA was detected by polymerase chain reaction (PCR) in 43.4% of FSWs. HPV16 was the most common type, found in 17.0% of samples, followed by HPV31 (9.4%). Age and smoking were associated with a significantly greater risk of being infected. The results of this study indicate that FSWs in Bulgaria are at increased risk for cervical cancer and represent an important source of HPV infection for the general population in the country. They should be considered as a priority group in cervical cancer control programmes.

Abstract
Persistent infection with oncogenic human papillomavirus (HPV) is a necessary causal factor in the development of cervical cancer. Moreover, HPV, predominately type 16 and to a lesser degree type 18, is linked causally to varying proportions of other anogenital cancers (vulva, vagina, penis, anus) as well as cancers elsewhere in the body (oropharynx, larynx, conjunctiva). HPV types 6 and 11 cause most of genital warts and recurrent respiratory papillomatosis. Effective prophylactic vaccines have been developed. In this review, we address briefly the immunological aspects of HPV infection and the results of HPV vaccination trials. Internationally standardized monitoring and evaluation of prophylactic HPV vaccination programmes will be essential for arriving at the most cost-effective strategies for cancer control.

Abstract
PURPOSE We examined p16, p21 and p53 expression in combination with the presence of human papillomavirus (HPV) DNA as molecular markers to predict survival in patients with stage IV hypopharyngeal squamous cell carcinoma (HSCC). METHODS Paraffin-embedded tumours from HSCC patients (n = 75) were evaluated for p16, p21 and p53 expression by immunohistochemistry. HPV DNA was detected by GP5+/6+ consensus PCR and subsequent genotyping by E6/E7 type-specific PCR for HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68. RESULTS Among the 61 specimens that tested positive for the β-globin, HPV typing identified 50 patients with high-risk (hr) HPV types. HPV 16E7 DNA was detected in 74% (37 cases) of these specimens. Twelve patients were found to be infected with multiple HPV types. However, the presence of hrHPV DNA was not found to correlate with the proportion of disease-free patients. The 5-year disease-free survival rate was 73% in p53- tumours versus 48% in p53+ tumours (P = 0.008). CONCLUSION In our series of patients with stage IV HSCC, the hrHPV+ subgroup had a similar prognosis (in terms of recurrence risk) as the HPV- subgroup. p53 overexpression was associated with a worse prognosis.
