The Prevalence of Cervical HPV Infection and Genotype Distribution in 856,535 Chinese Women with Normal and Abnormal Cervical Lesions: A Systemic Review. J Cytol 2022; 39:137-147. [PMID: 36605868 PMCID: PMC9809425 DOI: 10.4103/joc.joc_42_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 04/27/2022] [Accepted: 10/11/2022] [Indexed: 11/12/2022] Open
Abstract
Cervical cancer is the commonest cancer affecting women worldwide. During the last decades, the incidence and mortality rates of cervical cancer have increased in China. This research aims to assess the overall and genotype-specific prevalence of the human papillomavirus (HPV) infection among Chinese women with normal cervix, considering age, and geographic location. We selected studies about HPV prevalence in women from Chinese in Mainland China with normal cervix and abnormal cervical lesions, published between January 1995 and December 2020. The HPV prevalence was analyzed using meta-analysis based on the following: cytological and histological diagnoses, regions, and ages. The overall HPV prevalence in 856,535 women was 14.3%, 95% confidence interval (CI) and it increased from 8.2% to 16.5% in studies published from 2006 to 2020. The prevalence of high-risk (HR) and low-risk (LR) HPV types was 11.3% and 2.7%, respectively. The commonest types of HPV in women from Mainland China were HPV 16 (2.6%), 52 (2.4%), 58 (1.7%), 18 (0.9%), and 33 (0.8%). According to the geographical analysis, the prevalence of different HPV genotypes varied by region, Central China had the highest overall HPV prevalence. HPV16 was the commonest type in all the regions except in South China and East China, where HPV52 was found to be common. Regarding diagnosis, the HPV infection led to cervical cancer diagnosis by cytology and histology with 90.1% and 91.5% rates, respectively. HPV16 and HPV18 were common types associated with cervical cancer diagnosed by cytology and histology. HPV 16, 58, 52, 18, and 33 were the commonest types found in women with normal cervixes from Mainland China. The prevalence of different HPV genotypes varied by age group and region.

[PMID: 35692793 PMCID: PMC9175636 DOI: 10.3389/fonc.2022.812076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 04/11/2022] [Indexed: 11/13/2022] Open
Abstract
Objective This study aimed to compare the variability of HPV16/18/52/58 subtype infections in patients with different cervical lesions, to explore the guiding significance of persistent positive HPV subtypes 52 and 58 in the stratified management of cervical lesions, and to determine the appropriate management model. Method This study was conducted through a retrospective analysis of 244,218 patients who underwent HPV testing at the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University from September 2014 to December 2020 to examine the distribution of different types of HPV infection. From March 2015 to September 2017, 3,014 patients with known HPV underwent colposcopy to analyze high-risk HPV infection for different cervical lesions. Meanwhile, from September 2014 to December 2020, 1,616 patients positive for HPV16/18/52/58 alone with normal TCT who underwent colposcopy in our hospital were retrospectively analyzed for the occurrence of cervical and vulvovaginal lesions, with colposcopic biopsy pathology results serving as the gold standard for statistical analysis. Result Analysis of 244,218 patients who had HPV tested revealed that the top 3 high-risk HPV types were HPV52, HPV58, and HPV16. Further analysis of 3,014 patients showed that 78.04% of patients referred for colposcopy had HPV16/18/52/58 alone. Among high-grade squamous intraepithelial lesions (HSIL) and cervical cancer, the most common is HPV16, followed by HPV58 and then HPV52 (p < 0.05). A total of 1,616 patients with normal TCT who were referred for colposcopy due to HPV16/18/52/58 infection were further analyzed. Based on pathological findings in lesions of HSIL and CC, HPV16 is the most common, followed by HPV58 and then HPV18 (p < 0.05). In the 1,616 patients analyzed, high-grade vulvovaginal lesions were detected, with HPV58 being the most common, followed by HPV16 and then HPV52 (p < 0.05). Conclusion 1. In patients with positive HPV58 alone and normal TCT, the indications for colposcopy may be relaxed, with particular attention paid to the possibility of vulvar and vaginal lesions.2. Patients with a positive HPV type 52 alone and normal TCT may be considered for a follow-up review and, if necessary, a colposcopy.3. The development of a more suitable HPV vaccine for the Asian population, such as HPV16/18/52/58, may better protect women's health.

Trans R Soc Trop Med Hyg 2021; 115:30-37. [PMID: 32838408 DOI: 10.1093/trstmh/traa077] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 06/10/2020] [Accepted: 08/05/2020] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. METHODS In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. RESULTS The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p<0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16-24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p<0.05). CONCLUSIONS HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

Abstract
Determining the spatial distribution of human papillomavirus (HPV) and performing accurate public health analyses helps to distinguish areas of healthcare that require further research, and enables therapeutic techniques and approaches in healthcare to be focused more accurately. A total of 4,560 women were enrolled in the present study. Flow-through hybridization and gene chip assays were used to detect the genotypes of HPV infection. Heat maps were then generated to present the spatial distribution of HPV infections in Zhejiang Province according to genotype. Of the exfoliated cervical cell samples from the 4,560 women, HPV was detected in 1,886 samples. HPV-16, -58, -52 and -18 were the most prevalently identified genotypes in the population included in the present study. HPV-16 and -58 infections were mainly distributed in the northern and central regions of Zhejiang Province, such as in Hangzhou and Shaoxing, where the prevalence was higher than that in the southern regions (P<0.05). HPV-18 infection was widespread throughout Zhejiang Province, but had a much lower infection rate in Ningbo and Huzhou (P<0.05). High infection rates of HPV-52 were mainly detected in Hangzhou and the eastern coastal areas of Wenzhou, with a relatively low rate of infection in the center of the province (P<0.05). In conclusion, HPV-16, -58, -52 and -18 were the four most prevalent HPV genotypes observed in Zhejiang Province. Heat maps were created to display the spatial distribution of HPV infection according to genotype, which varied by geographical regions. The results indicate that for individuals in Ningbo or Wenzhou, bivalent or quadrivalent vaccines may be suitable, but for those in Hangzhou and Shaoxing, nonavalent vaccines are strongly recommended.

Abstract
Objective Rapid, high-volume screening programs are needed as part of cervical cancer prevention in China. Methods In a 5-day screening project in Inner Mongolia, 3345 women volunteered following a community awareness campaign, and self-swabbed to permit rapid HPV testing. Two AmpFire™ HPV detection systems (Atila Biosystems) were sufficient to provide pooled 15-HPV type data within an hour. HPV+ patients had same-day digital colposcopy (DC) performed by 1 of 6 physicians, using the EVA™ system (MobileODT). Digital images were obtained and, after biopsy of suspected lesions for later confirmatory diagnosis, women were treated immediately based on colposcopic impression. Suspected low- grade lesions were offered treatment with thermal ablation (Wisap), and suspected high-grade lesions were treated with LLETZ. Results Of 3345 women screened, 624 (18.7%) were HPV+. Of these, 88.5% HPV+ women underwent same-day colposcopy and 78 were treated. Later consensus histology results obtained on 197 women indicated 20 CIN2+, of whom 15 were detected and treated/referred at screening (10 by thermal ablation, 4 by LLETZ, 1 by referral). Conclusions Global control of cervical cancer will require both vaccination and screening of a huge number of women. This study illustrates a cervical screening strategy that can be used to screen-and-treat large numbers of women. HPV self-sampling facilitates high-volume screening. Specimens can be tested rapidly, promoting minimal loss-to-follow-up. Specifically, the AmpFire™ system used in this study is highly portable, simple, rapid (92 specimens per 65 min per unit), and economical. Visual triage can be performed on HPV+ women with a portable digital colposcope that provides magnification, lighting, and a recorded image. Diagnosis and appropriate treatment remain the most subjective elements. The digital image is under study for deep-learning based automated evaluation that could assist the management decision, either by itself or combined with HPV typing.

Abstract
Human papillomavirus (HPV) type 58 is the third most commonly detected HPV type in cervical cancer among Eastern Asians. Our previous international epidemiological studies revealed that HPV58 carrying an E7 natural variant, T20I/G63S (designated V1), was associated with a higher risk of cervical cancer. We recently showed that V1 possesses a greater ability to immortalize and transform primary cells, as well as degrading pRB more effectively, than the prototype and other common variants. In this study, we performed a series of phenotypic and molecular assays using physiologically relevant in vitro and in vivo models to compare the oncogenicity of V1 with that of the prototype and other common natural variants. Through activation of the AKT and K-Ras/extracellular signal-regulated kinase (ERK) signaling pathways, V1 consistently showed greater oncogenicity than the prototype and other variants, as demonstrated by increased cell proliferation, migration, and invasion, as well as induction of larger tumors in athymic nude mice. This study complements our previous epidemiological and molecular observations pinpointing the higher oncogenicity of V1 than that of the prototype and all other common variants. Since V1 is more commonly found in eastern Asia, our report provides insight into the design of HPV screening assays and selection of components for HPV vaccines in this region.IMPORTANCE Epidemiological studies have revealed that a wild-type variant of HPV58 carrying an E7 variation, T20I/G63S (V1), is associated with a higher risk of cervical cancer. We previously reported that this increased oncogenicity could be the result of the virus's greater ability to degrade pRB, thereby leading to an increased ability to grow in an anchorage-independent manner. In addition to this, this report further showed that this HPV variant induced activation of the AKT and K-Ras/ERK signaling pathways, thereby explaining its genuine oncogenicity in promoting cell proliferation, migration, invasion, and formation of tumors, all to a greater extent than the prototype HPV58 and other common variants.

Abstract
OBJECTIVE Implementation of a novel, rapid, high-volume, see-and-treat cervical cancer screening programme using self-swab human papillomavirus (HPV) testing and digital colposcopy in underserved regions of Yunnan China. DESIGN 480-980 women per day self-swabbed for high-risk HPV (hrHPV+). Four careHPV machines (Qiagen) were run simultaneously to test the specimens. All hrHPV+ patients were contacted the same day and digital colposcopy was performed with the enhanced visual assessment system (MobileODT). Digital images were obtained, and all suspected lesions were biopsied and then treated. SETTING Rural and underserved areas of the Yunnan province, Kunming municipality. PARTICIPANTS 3600 women, mean age 50.2 years, who had never been screened for cervical cancer. The women were of the Yi, Hui, Dai and Han ethnicities. INTERVENTIONS Cryotherapy was performed on all lesions suspicious for cervical intraepithelial neoplasia (CIN) 1 and loop electrosurgical excision procedure was performed on all lesions suspicious for ≥CIN2. Endocervical curettage was performed if the transformation zone was not fully visualised. RESULTS 216 women (6%) were hrHPV+. 168 underwent same-day colposcopy (23 CIN1, 17≥CIN2). Digital colposcopy was able to identify 15 of 16 (93.8%)≥CIN2 lesions. CONCLUSIONS This study illustrates a high-volume, rapid and practical strategy that can be used to screen and treat an ethnically diverse group of Chinese women. First, HPV self-sampling allows large numbers of women to be screened rapidly and relatively inexpensively. Only hrHPV+ women will then require further evaluation. Digital colposcopy is then performed on hrHPV+ women with a portable digital colposcope. The high-resolution images obtained can facilitate appropriate same-day treatment as they are able to accurately distinguish between CIN1 and ≥CIN2 lesions.

Abstract
Background and Objective Human papillomavirus (HPV) testing has become a preferred cervical cancer screening. However, most HPV infections are harmless and additional tests are required to screen HPV positive women. The objective of this study is to determine the optimal triage strategies for HPV positive women in China’s rural population. Methods A population-based screening was performed at seven rural counties of Jiangxi province, between October 2014 to January 2016. A total of 18,000 women aged 35–64 years were enrolled in this study. The primary screening was performed using CareHPV, HC-2, Cobas ®4,800 or HybriMax. Positive women were further screened with five triage tests: (1) Liquid-based cytology test (LBC); (2) conventional Pap cytology test (Pap smear); (3) HPV16, 18 detection; (4) viral load; and (5) visual inspection with acetic acid and Lugol’s iodine (VIA/VILI). Women who were tested positive were referred for colposcopy. The five triage tests were compared with respect to sensitivity, specificity, referral rate, cost and diagnostic time. Results Complete data were available for 17,782 women. The HPV prevalence was 13.6%. Referral rates for colposcopy were 4.5%, 2.8%, 2.8%, 6.6%, and 3.7% with LBC, Pap smear, HPV16/18, viral load, and VIA/VILI, respectively. The sensitivity of the above triage tests was 65.8%, 51.9%, 86.8%, 73.3%, and 41.7%, respectively. The specificity was 69.8%, 81.0%, 85.8%, 52.2% and 65.3%, respectively. The average time to diagnosis was significantly lower with HPV16/18, viral load and VIA/VILI than LBC and Pap smear. In addition, screening cost that leads to identify one HSIL+ woman was the lowest with viral load. Conclusion Our data indicate that HPV16/18 and viral load are the optimal triage strategies for HPV screening in China’s rural population.

Abstract
BACKGROUND The objective of this study was to examine the prevalence of human papillomavirus 16/18 (HPV-16/18) genotypes and immediate histopathologic correlations in a Chinese population with negative cytology and positive high-risk human papillomavirus (hrHPV) testing. METHODS Patients who had documented negative cytology with immediate follow-up (within the 6 months after negative for intraepithelial lesion or malignancy Papanicolaou [Pap] testing), including a histopathologic examination and/or hrHPV testing, between 2011 and 2018 were included, and the data were analyzed. RESULTS Among 1,424,182 Pap tests, 1,333,453 (93.6%) were interpreted as negative cytology. Although conventional Pap smears had the highest reporting rate, cervical intraepithelial neoplasia 2 and higher (CIN-2+) lesions were detected significantly more with liquid-based cytology preparations (2.1%) than the conventional method (1.4%; P < .01). The overall hrHPV-positive rate was 14.9% (25,507 of 171,273) in the women with negative cytology. Among the 18,423 cytology-negative, HPV-positive cases tested with the Cobas assay, the overall HPV-16/18 prevalence was 24.7%, with 17.9% being HPV-16-positive, 6.2% being HPV-18-positive, and 0.6% being positive for both HPV-16 and HPV-18. The immediate histopathologic examination was documented for 21,796 women with cotesting results, including 8915 HPV-positive cases and 12,881 HPV-negative cases. CIN-2+ lesions were diagnosed in 15.2% of the HPV-16-positive cases; this rate was significantly higher than the rates seen in the HPV-18-positive cases (4.8%) and the cases positive for 1 of the other 12 types of HPV (3.0%). CONCLUSIONS This is by far the largest routine clinical practice report of HPV-16/18 genotyping and histopathologic examination in negative-cytology women and the first report of such an investigation in the Chinese population. This study indicates enhanced risk stratification with HPV-16/18 genotype testing in HPV-positive, cytology-negative women in the Chinese population.

Telomere length in cervical exfoliated cells, interaction with HPV genotype, and cervical cancer occurrence among high-risk HPV-positive women. Cancer Med 2019; 8:4845-4851. [PMID: 31243901 PMCID: PMC6712472 DOI: 10.1002/cam4.2246] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2019] [Revised: 05/01/2019] [Accepted: 05/02/2019] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Although high-risk human papillomavirus (HR-HPV) infection is recognized as the main cause of cervical cancer, only a minority of HPV-infected women develop this malignancy. Increasing evidence suggests that alterations of telomere length might be implicated in carcinogenesis. However, the association between cervical cancer and telomere length remains unknown. METHODS This case-control study included 591 cervical cancer patients and 373 cancer-free controls, all of whom were infected with HR-HPV. Relative telomere length (RTL) in cervical cancer exfoliated cells was measured by quantitative PCR. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression analysis. RESULTS HPV16, 18, 52, and 58 were common in both case and control groups. The proportion of HPV16 infection tended to increase across the quartiles of RTL (Ptrend < 0.001). There was no statistically significant association of RTL with tumor differentiation, histological type, and FIGO stage. After adjustment for age and HPV types, the lowest quartile of RTL presented a 49% lower risk (OR = 0.51, 95% CI: 0.35, 0.76; P < 0.001) than those with the highest quartile of RTL. There was also a dose-response relationship of shorter RTL on lower risk of cervical cancer (Ptrend < 0.001). CONCLUSION Shortened telomere length in cervical exfoliated cells was related to the lower risk of cervical cancer among HR-HPV-positive women, which might help to improve cervical cancer screening and surveillance. Further prospective studies with large sample should be designed to validate our preliminary findings, and evaluate the potential efficacy of telomere length for cervical cancer screening.

Abstract
Accumulating evidence indicates that persistent infection with high-risk oncogenic human papillomavirus (HPV) genotypes is the most important risk factor for cervical cancer, and that the distribution of HPV genotypes varies regionally. This study explored the prevalence and genotype distribution of HPV infection among Han, Yi, and Bai women in various regions of Dali Bai Autonomous Prefecture, Yunnan Province, China. This cross-sectional study included 2779 women (20-76 years old) who were referred for 21-HPV genotype array diagnostic from five regions of Dali Bai Autonomous Prefecture between February 2013 and May 2016. Statistical methods used included a the χ2 test, Fisher's exact test, t test, and logistic regression. Overall HPV prevalence in the study population was 7.6%. HPV-52, HPV-58, HPV-18, HPV-81, and HPV-16 were the most prevalent genotypes in the study area, and notably, the prevalence of HPV-58 was significantly higher among women in Heqing County than that in other regions. Univariate analysis showed that husband's age, region, fertility status, and parity were potential factors associated with HPV infection. Multivariate logistic regression analysis revealed that Heqing County was an independent risk factor for HPV infection among women in the Dali area, moreover, Yi women showed the highest risk for HPV infections. Overall, our finding emphasizing the urgent need for an HPV screening and prevention program in Heqing County and Yi women. We also suggest that HPV-related health education should be provided not only to women, but also to men, to reduce the risk of infection in women.

Role of genomic DNA methylation in detection of cytologic and histologic abnormalities in high risk HPV-infected women. PLoS One 2019; 14:e0210289. [PMID: 30608989 PMCID: PMC6319776 DOI: 10.1371/journal.pone.0210289] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Accepted: 12/19/2018] [Indexed: 12/21/2022] Open
Abstract
Cervical cancer is the fourth most common malignancy affecting women worldwide. The development of disease is related to high-risk human papillomavirus (hrHPV) infection. Cytology has been the most recommended triage for primary cervical (pre)cancer screening despite relatively low sensitivity. Recently, genomic DNA methylation has been proposed as an additional marker to increase sensitivity for detecting cervical precancerous lesion. This study aimed to evaluate the performance of methylation status of three tumor suppressor genes (CADM1, FAM19A4, and MAL) and HPV genotyping in detection of cytologic and histologic abnormalities in cervical cancer screening. Two hundred and sixty samples with available frozen cell pellets including 70 randomly selected cases of negative for intraepithelial lesion or malignancy (NILM)&HPV-negative, 70 randomly selected cases of NILM&HPV-positive, and 120 cytologic abnormalities & HPV-positive from a population-based cervical cancer screening program (n = 7,604) were investigated for the DNA methylation pattern of CADM1, FAM19A4, and MAL. Of 120 cytologic abnormalities & HPV-positive cases, there were 115 available histologic results. HPV52 and HPV58 were most commonly found in histologic HSIL+. The methylation levels of CADM1, FAM19A4, and MAL were elevated with the severity of cytologic abnormality which significantly increased by 3.37, 6.65 and 2 folds, respectively, in cytologic HSIL comparing with NILM. A significant increase in methylation levels of these three genes was also observed in histologic HSIL+ compared with negative histology but only CADM1 showed a significant higher methylation level than histologic LSIL. Using the ROC curve analysis, DNA methylation levels of FAM19A4 performed best in differentiating high-grade cytology (ASC-H+ from NILM/ASC-US/LSIL), followed by CADM1 and MAL. Whilst the CADM1 methylation performed best in distinguishing histologic HSIL+ from negative/LSIL with an area under the ROC curve of 0.684, followed by MAL (0.663) and FAM19A4 (0.642). Interestingly, after combining high DNA methylation levels to HPV16/18 genotypes, rates of histologic HSIL+ detection were substantially increased from 25% to 79.55% for CADM1, 77.27% for FAM19A4, and 72.73% for MAL, respectively. The rate further increased up to 95.45% when at least one of three genes had a high methylation level. This suggests a possible role of genomic DNA methylation, especially CADM1, in detecting histologic HSIL+ lesions in combination with hrHPV testing.

Abstract
Human papillomavirus 58 (HPV58) ranks the second or third in East Asian cervical cancers. Current studies on HPV58 are scarce and focus on the prototype. Previously, we identified the three most common circulating HPV58 E7 strains contained amino acid alterations: G41R/G63D (51%), T20I/G63S (22%) and T74A/D76E (14%) respectively. Among them, the T20I/G63S variant (V1) had a stronger epidemiological association with cervical cancer. We therefore suggested that V1 possessed stronger oncogenicity than the other two variants. Here, we performed phenotypic assays to characterize and compare their oncogenicities with HPV58 E7 prototype. Our results showed that overexpression of V1 conferred a higher colony-forming ability to primary murine epithelial cells than prototype (P < 0.05) and other variants, implicating its higher immortalising potential. Further experiments showed that both V1 and prototype enhanced the anchorage-independent growth of NIH/3T3 cells (P < 0.001), implicating their stronger transforming power than the two other variants. Moreover, they possessed an increased ability to degrade pRb (P < 0.001), which is a major effector pathway of E7-driven oncogenesis. Our work represents the first study to compare the oncogenicities of HPV58 E7 prototype and variants. These findings deepened our understanding of HPV58 and might inform clinical screening and follow-up strategy.

Abstract
Background Human papillomavirus (HPV) is recognized as an important risk factor for laryngeal carcinogenesis. Although HPV-16 and 18 have been strongly implicated, the presence of other high-risk HPV (HR-HPV) genotypes or the coinfection with Epstein-Barr virus (EBV) or Merkel cell polyomavirus (MCPV) may increase the risk, but their etiological association has not been definitively established. Methods We characterized the genotype-specific HPV and the frequency of EBV and MCPV infections through the detection of their DNA in 195 laryngeal specimens of squamous cell carcinoma (SCC) histologically confirmed. Results HPV DNA was detected in 93 (47.7%) specimens. HPV-11 was the most frequent with 68 cases (73.1%), and HPV-52 was the most frequently HR-HPV found with 51 cases, which corresponds to 54.8% of all HPV-positive specimens. EBV DNA was detected in 54 (27.7%) tumor tissue specimens of which 25 (46.3%) were in coinfection with HPV. MCPV DNA was detected only in 11 (5.6%) cases of which 5 (45.4%) were in coinfection with an HR-HPV. No association between the presence of DNA of the three examined viruses and the patient smoking habits, alcohol consumption, age, the keratinization status, differentiation grade, or localization of the tumor in the larynx were found. Discussion HPV-52 was the most prevalent HR-HPV, which may suggest that this and other genotypes in addition to HPV-16 and 18 could be considered for prophylaxis. However, further studies including non-cancer larynx cases and the evaluation of other molecular markers and viral co-infection mechanisms are needed to determine the role of the different HR-HPV genotypes, EBV, and MCPV in the etiology of SCC of the larynx.

Abstract
Sero-epidemiological studies of human papillomavirus (HPV) have been undertaken over the last two decades. In this study, the prevalences of nine serum antibodies (anti-E6, E7 and L1 antibodies of HPV types 16, 18, and 58) were evaluated in normal (control) Korean women and women with cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III, and cervical cancer. The frequencies of all types of anti-HPV antibodies were higher in the CIN stages and cervical cancer than in normal women, and those of anti-HPV16 E6 and E7, anti-HPV18 E6 and E7, and anti-HPV58 E7 antibodies were higher in the cervical cancer group than in the CIN stages. The frequencies of antibodies against HPV16, 18, and 58 E7 tended to increase with increasing severity of cervical lesions. However, there were few differences in the frequencies of antibodies against the L1 antigens of HPV16, 18 and 58 in cervical cancer versus CIN stages. The anti-HPV antibodies were detected in 26.5% of normal, 46.3% of CIN I, 62.5% of CIN II, 51.6% of CIN III, and 75% of cancers when any of the nine antigens was used as a criterion. Correlations between HPV DNA positivity and seropositivity for anti-HPV E6, E7, or L1 antibodies were found only in HPV16 DNA-positive cervical cancers for anti-HPV16 E6 and L1 antibodies. In addition, strong positive correlations in seropositivity were found between anti-HPV16 E7 and anti-HPV58 E7 antibodies, and between anti-HPV18 E6 and anti-HPV58 E6 antibodies. These findings should advance global profiling of the seroprevalences of antibodies against HPV antigens.

Abstract
Cervical cancer is one of the leading causes of cancer-related deaths among women and it is caused by the human papillomavirus (HPV). High variation has been reported in the attribution of specific HPV genotypes to cervical neoplasia among various geographic regions. For effective control of cervical cancer through HPV vaccination, it is essential to estimate the cost-effectiveness of vaccination, to monitor the potential transition into other HPV genotypes, and to understand the distribution of specific HPV genotypes across a specific geographic region. In this study, the distribution of HPV genotypes was investigated in southeast China, from 2011 to 2016. The 12,816 cervical swabs collected from women (age 18–78 years, median 43.6 years) outpatients were analyzed. HPV prevalence among 12,816 cervical swabs analyzed was 22.3% (2,856/12,816). Among these positive cases, 2,216 had only one HPV genotype while 640 had multiple HPV genotypes. The cases with multiple types revealed 23 different HPV genotypes with the five most prevalent being HPV18 (18.2%), HPV52 (14.1%), HPV16 (11.9%), HPV58 (10.6%), and HPV33 (5.5%). The rates of HPV infection in patients with cervical inflammation, CIN-1, CIN-2, CIN-3, squamous carcinoma, and adenocarcinoma were 38.4%, 80.5%, 82.6%, 92.3%, 97.5%, and 93.4%, respectively. Four HPV genotypes, HPV18, HPV16, HPV52, and HPV58, were more prevalent in patients with CIN-2-CIN-3 and invasive cervical cancer. A comparison of HPV genotypes attribution to cervical cancer between southeast China and global incidences revealed distinct differences. Due to this unique prevalence, it is essential to streamline the vaccination development protocol prior to administering vaccines based on global data.

Abstract
To examine validity of the hybrid capture-2 and cobas 4800 HPV tests, 396 women including 188 women visiting for cancer screening, and 208 referral cases were examined with both HPV tests and the liquid-based cervical Pap test. Concordant results between the HPV assays were observed in 333 cases (coincident rates; 84.1%, kappa value; 0.682). The sensitivity for CIN2+ was 98.6% (69/70) and 82.9% (58/70) for HC2 and cobas 4800 (McNemar's test; P = 0.0026). The sensitivity for CIN3+ was 97.2% (35/36) and 83.3% (30/36) (Not significant, P = 0.0736). The specificities for CIN2+ or CIN3+ did not differ between the tests. The HPV16, 52, 18, 31, and 58 were the most common types in CIN2+ cases. Reasonable sensitivity for HPV52, and cross-hybridization with some probable high-risk HPV type such as HPV82 explain the higher sensitivity of HC2 than cobas 4800 in detection of CIN2+ in a referral population in Japan.

Prevalence of human papillomavirus genotypes and relative risk of cervical cancer in China: a systematic review and meta-analysis. Oncotarget 2018; 9:15386-15397. [PMID: 29632652 PMCID: PMC5880612 DOI: 10.18632/oncotarget.24169] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2017] [Accepted: 12/06/2017] [Indexed: 11/25/2022] Open
Abstract
High-risk HPV (hrHPV) is related to cervical carcinogenesis, although clinical data comparing the natural history and carcinogenic potential of type-specific HPV remain limited. Furthermore, the nationwide prevalence rates of overall and type-specific HPV among women with cervical precancerous lesions and cancer have not been reported. Here, a meta-analysis was performed for type-specific HPV distribution among 30,165 HPV-positive women, including 12,094 invasive cervical cancers (ICCs), 10,026 cervical intraepithelial neoplasia grade 2/3 (CIN2/3), 3246 CIN1, and 4799 normal cervices from 45 PCR-based studies. We found that HPV16 was the most common hrHPV type involved in cervical disease. The HPV16 positivity rate varied little across normal (22.7%) and CIN1 individuals (23.6%) but increased through the CIN2 (37.6%) and CIN3 patients (51.9%) to 65.6% in ICC cases. HPV16, 18, 35, 39, 45, and 59 were more frequent in ICC than CIN3, with ICC:CIN3 ratios ranging from 2.3 for HPV18 to 1.1 for HPV35/45. HPV31, 33, 52, and 58 were more frequent in CIN3 compared with normal cervices but less common in ICC compared with CIN3 (ICC:CIN3 ratios ranging from 0.6 for HPV58 and 0.4 for HPV52). The ICC:normal ratios were particularly high for HPV18, 52 and 58 in West China (4.1, 3.9 and 2.9, respectively) and for HPV45 and 59 in North China (1.6 and 1.1, respectively). In summary, this study is the most comprehensive analysis of type-specific HPV distribution in cervical carcinogenesis and could be valuable for HPV-based cervical cancer screening strategies and vaccination policies in China.

Abstract
The clinical performance of the newly developed MeltPro® HPV Test, based on multicolor melting curve analysis, was evaluated and compared with the commercially available Cobas® HPV Test for detection of HPV and genotyping of HPV-16 and HPV-18. A total of 1647 cervical samples were analyzed with both tests. The agreement values were 96.2% for HPV detection, 99.6% for HPV-16 identification, and 99.7% for HPV-18 identification. All genotyping results from MeltPro® HPV Test showed that HPV-52, HPV-58, and HPV-16 were the most common types in this study. Intra-laboratory reproducibility studies showed 97.8% agreement while inter-laboratory reproducibility studies showed 96.9% agreement for the MeltPro® HPV Test. The MeltPro® HPV Test and Cobas® HPV Test are highly correlative and are useful for monitoring HPV infection.

Cervical Cancers Manifest a High Rate of Infection by a High-Risk Human Papilloma Virus Subtype but a Very Low Rate of Infection by a Low-Risk Subtype in the Guiyang District of China. J Cancer 2017; 8:1263-1270. [PMID: 28607602 PMCID: PMC5463442 DOI: 10.7150/jca.17120] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2016] [Accepted: 03/31/2017] [Indexed: 11/05/2022] Open
Abstract
The prevalence of infection by different genotypes of human papillomavirus (HPV) varies among different geographic areas. We studied the prevalence of infection by 21 HPV genotypes in cervical tissue specimens from 4213 women in the Guiyang district, that is located in the southwest of China and is dominated by minor ethnicities of Chinese, and 2074 cases in our cohort had pathological diagnosis available. The overall infection rate was 36.98%. Most (72.08%) infectors were positive for only one HPV subtype, with the remaining being cases infected by two or more subtypes. Infections by the HPV subtypes 16, 52 and 58 were the most prevalent, having rates of 34.66%, 16.03%% and 15.53%, respectively. The most common cervical lesions in HPV infections were genital warts, cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). Age and age at first sexual activity were independent risk factors for HPV infections that in turn cause certain cervical lesions. Intriguingly, while 94.90% of the CC patients were infected by oncogenically high-risk (HR) HPV subtypes, only 2.75% and 2.29% of these patients were infected by oncogenically low-risk (LR) subtypes or other-subtypes with their oncogenicity unclear. The rates of infection by LR-HPVs and other-HPVs were also low, being 4.63% and 6.76%, respectively, in the patients with CIN that is a precursor lesion of CC, lower than the 8.54% and 18.20%, respectively, in the women without a cervical lesion. Our data provides an important foundation for prevention, diagnosis and treatment of HPV infection in Guiyang district and suggests that development of vaccines for prevention and treatment of CC in this area should first target the HPV subtypes 16, 52 and 58, but not subtype 18 as for many other places. It deserves study whether infections by certain LR-HPVs and other-HPVs may serve as attenuated live vaccines for prevention of CC.

Abstract
Human papillomavirus (HPV) is a DNA virus that belongs to the papillomavirus family and is capable of infecting humans. Currently, few vaccines are available to prevent infection by HPV. However, they are not so much effective and provide little benefit to women who have already been infected with HPV. The aim of this study was to design epitope-based vaccines of HPV58 by targeting E6 and E7 proteins of HPV58. Proteomic sequences were retrieved from different isolates at different time periods and later analyzed by performing alignment of these sequences. To ensure the capacity of humoral and cell-mediated immunity, both B cell and T cell immunity were checked for the peptides. For E6 protein, the peptide sequence from 48 to 54 amino acids and one 9-m epitope ETSVHEIEL were the most potential B cell and T cell epitopes, respectively. This peptide could interact with as many as eight MHC-1 alleles and showed high population coverage up to 90.31 %. On the other hand, the peptide region for the E7 protein ranged from 27 to 33 amino acids and two 9-m epitopes QAQPATANY, SSDEDEIGL were found as the most potential B cell and T cell epitopes, respectively. The peptide sequences could interact with as many as seven MHC-1 alleles and showed population coverage up to 90.31 %. Furthermore, conservancy analysis was also performed using in silico tools and showed a conservancy of 100 % for all the selected epitopes. In addition to this, the allergenicity of the epitopes was also evaluated. Although the study requires further in vitro and in vivo screening, this epitope-focused peptide vaccine designing opens up a new skyline that holds a prospective future in HPV research.

Abstract
Background This study was designed to determine the Human papillomavirus (HPV) prevalence and its distribution of genotypes in various regions of Yunnan Province, China. Method In this study, participants were recruited during routine gynecologic examination between Oct 2013 and Feb 2015. A total of 17,898 women were recruited. Polymerase chain reaction was used for detecting the HPV positive samples and HPV geno-array test was used for genotyping. Results The overall HPV infection rate (19.9 %) among the south-western women was significantly higher (P = 0.001) than that among the north-western (18.0 %), south-eastern (13.3 %), north-eastern (11.1 %) and central women (12.9 %). The high-risk (HR) (18.1 %, P = 0.001) and single genotype (16.7 %, P = 0.001) infection rates among the South-western women were also significantly higher than those of among the north-western (13.9 %, 11.3 %), south-eastern (11.6 %, 10.5 %), north-eastern (9.6 %, 9.1 %) and central women (10.5 %, 10.0 %), respectively. While, the infections with multiple HPV (4.2 %) genotypes were significantly more common (P = 0.001) among women in north-western Yunnan than women in the south-western (1.3 %, 3.1 %), south-eastern (1.7 %, 2.7 %), north-eastern (1.5 %, 2.0 %) and central Yunnan (2.4 %, 2.9 %). A total of 30 HPV genotypes were detected; among them 13 were HR-HPV, 3 were PHR-HPV (Potential High risk), 8 were LR-HPV (Low risk) and six were unclassified. The most common HPV genotypes were HPV-52, 16, 58, 53 in control group, HPV-16, 52, 58, 39 and 53 in CINI (Cervical intraepithelial Neoplasia), HPV-52, 16, 58, 33, 53 and 81 in CINII, HPV16, 58, 18, 52, 81 in CINIII and HPV-16 18, 58, 52 in cervical cancer (CC), respectively. Such variation has also been observed about distribution of HPV genotypes distribution among single and multiple infections. Conclusion This study gives an epidemiological estimate of HPV prevalence and different genotype distribution in various region of Yunnan province and further explains its prevalence in different neoplastic lesions. Overall HPV-16, 52, 58, and 18 are the leading HR-HPV genotypes.

Abstract
The prevalence and genotype distribution of human papillomavirus (HPV) vary throughout the world. To assess the prevalence and genotype distribution of HPV among three ethnic groups in two geographic locations in north-western Yunnan, we recruited 522 women in Shangri-le (n = 255) and Lijiang (n = 267). PCR amplification of HPV DNA was performed on cervical cells from these women using two consensus primer systems (MY09/11 and GP5/6). Amplified-HPV DNA was genotyped using the HPV GenoArray test. Geographically, the HPV prevalence was significantly higher (P = 0.002) among Shangri-le women than among Lijiang women. Infections with high-risk (HR)-HPV and with multiple HPV genotypes were also significantly more common (P = 0.001) among women in Shangri-le than women in Lijiang. Additionally, the prevalence of overall, HR-HPV, and single genotype HPV infections was significantly higher (P = 0.001) among Tibetan women than among Naxi and Han women. HPV-16 and HPV-33 were significantly more frequent in Shangri-le women compared with Lijiang (P = 0.006) women. In addition, HPV-16 (9.81%) and HPV-33 (5.88%) were significantly more prevalent in Tibetan women than in Naxi and Han women. Here, for the first time, we highlight the significant variation in the prevalence and genotype distribution of HPV in various populations in the north-western region of Yunnan Province.

Abstract
Human Papillomavirus (HPV) is the most common sexually transmitted infection worldwide and it is responsible for most cases of uterine cancer. In Ecuador there is limited information about HPV types (and variants) in cancerous lesions; however, identifying the type-specific HPV prevalence in cervical lesions of women living in Ecuador is important to better predict the impact of HPV prophylactic vaccination in this country. We studied the prevalence of HPV types in cervical cancerous or precancerous lesions from 164 Ecuadorian women and found that 86.0% were HPV positive. The most common types were HPV16 (41.8%) and HPV58 (30.5%). Interestingly, HPV18 was detected only in 2.8% of the HPV-positive samples. Fifteen DNA sequences (genes E6 and L1) from 16 samples positive for HPV16 belonged to the European lineage, considered one of the least carcinogenic lineages, and 1 (6.25%) to the Asian-American lineage. Similar analysis in 12 HPV58 positive samples showed that 10 (83.3%) sequences grouped in sublineage A2, which belongs to the oldest HPV58 lineage, 1 belonged to A3 and 1 to lineage C. This study suggests that the currently used HPV vaccines (bivalent and tetravalent) may have lower effectiveness in Ecuador than in other geographic locations where HPV18 is more prevalent.

Abstract
We compared multiplex E6 messenger ribonucleic acid (mRNA) tests using real-time quantitative reverse transcriptase polymerase chain reactions (PCR) with human papillomavirus (HPV) DNA subtypes using a MY11/GP6+ PCR-based reverse-blot assay to identify cervical intraepithelial neoplasias of grade 2 or worse (CIN2+). In total, 684 women were studied, of whom 377 (55%) were diagnosed with CIN2+ histologically. The specificity of HPV mRNA to predict histological CIN2+ was higher than that of HPV DNA (81.3% vs. 44.2%). The odds ratios (ORs) to predict histological CIN2+ in women with positive for type 16, 18, 31, and 45 E6 mRNA or by HPV DNA detection were 7.1 (95% confidence interval [CI] 3.9-13.1) and 2.5 (95%CI 1.9-3.5), respectively, compared to those with negative for E6 mRNA or HPV DNA. The OR to predict histological CIN2+ in women with a cytological grade <CIN2+ and positive for type 16, 18, 31, and 45 E6 mRNA was 9.7 (95%CI 3.2-29.2), compared to those with a cytological grade <CIN2+, and negative for E6 mRNA (OR = 1), those with a cytological grade CIN2+, and negative for mRNA (OR = 6.9, 95%CI 4.4-10.8), and those with a cytological grade CIN2+ and positive for mRNA (OR = 28.0, 95%CI 9.8-79.6). As a HPV DNA positive triage, the OR to predict histological CIN2+ in women with a cytological grade <CIN2+ and positive for mRNA was higher than those with negative for mRNA (OR:12.8 [95%CI 3.6-5.4] vs. OR:1.6 [95%CI 0.9-2.9]). In conclusion, multiplex HPV E6 mRNA detection can be used as a triage for women with cytological grade <CIN2+.

Abstract
A number of reports have identified HPV DNA in breast cancer specimens and HPV type 16, 18, 31, 33, 45, and 51 were more prevalent. HPV 58 was frequently detected in cervical cancer in Shaanxi China. The aim of the present study was to investigate whether HPV 58 present in breast cancer. 169 cases of breast cancer samples and 83 benign breast lesions were analyzed. Type specific primers and oligonucliotide probe were used for the detection of HPV 58 by conventional PCR and in situ hybridization techniques. The HPV 58 viral load were measured by qPCR. p16 protein expression were evaluated by immunohistochemistry. HPV 58 E7 DNA was detected in 25 out of 169 formalin fixed paraffin embedded breast cancer tissues (14.79%) by PCR, only 1 out of 83 non-malignant breast lesions showed positive (1.20%). The results of ISH showed that 17 out of 169 (10.06%) malignant samples were positive for HPV 58 E7, and only 1 out of 83 non-malignant lesions was positive. Positive p16 immunostaining was observed in all the HPV 58 E7 ISH positive cases, but 16 out of 98 cases with HPV negative were p16 positive. The presence of HPV 58 in both normal duct epithelial cells and carcinoma in situ along with its presence in the cancer cells of the same specimen indicated the possible causal role of HPV 58 in breast cancer. The findings provide a solid morphological evidence of the involvement of HPV 58 in breast cancer development.

Abstract
To investigate the distribution of high-risk human papillomavirus (HPV) genotypes in infected women from Beijing, China, samples were obtained during routine gynecologic examinations and DNA was extracted from the samples, and PCR was performed to distinguish the 13 high-risk HPV subtypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68). Samples were obtained from 1160 women (20-75 years old), and 470 cases of high-risk HPV infection were diagnosed. HPV 52, HPV 16, HPV 58, HPV 51, and HPV 39 were the most common genotypes accounting for 22.8%, 22.3%, 20.0%, 14.3%, and 13.6% of cases, respectively. The highest infection rates were found in 20-30 year-old patients (35.1%). HPV 16 infection was the highest in the 31-40 year-old group, and HPV 52, HPV 58, and HPV 39 infections were highest in the 20-30 year-old group. Some patients were infected with multiple high-risk HPV subtypes. Of the 470 patients with positive HPV tests, 65.7% of women were infected with a single high-risk HPV subtype, 23.2%, of women were infected with two high-risk HPV subtypes, 7.7% were infected with three subtypes, and 3.4% of women were infected with more than three high-risk HPV subtypes. In this study, HPV 16 and HPV 52 were the most common subtypes found in patients with cervical lesions.

Abstract
The newly gained knowledge of the viral etiology in cervical carcinogenesis has prompted industrial interests in developing virology-based tools for cervical cancer prevention. Due to the long incubation period from viral infection to developing an invasive cancer, a process whose outcome is influenced by numerous life-style and genetic factors, the true efficacy of the genotype-specific human papillomavirus (HPV) vaccines in cervical cancer prevention cannot be determined for another 30 years. Most HPV DNA test kits designed to replace the traditional Papanicolaou (Pap) smears for precancer detection lack the analytical sensitivity and specificity to comprehensively detect all potentially carcinogenic HPVs and to perform reliable genotyping. The authors implemented the classic nested PCR and Sanger DNA-sequencing technology for routine HPV testing. The results showed a true negative HPV PCR invariably indicates the absence of precancerous cells in the cytology samples. However, 80.5% of single positive HPV-16 tests and 97.3% of single positive HPV-18 tests were associated with a negative or a largely self-reversible Pap cytology. Routine sensitive and reliable HPV type-specific or perhaps even variant-specific methods are needed to address the issues of persistence of HPV infection if a virology-based primary cervical screen is used to replace the Pap cytology screening paradigm.

Abstract
Objective To estimate the prevalence and attribution of two non-vaccine-covered HPV types (HPV52 and HPV58) across the world. Methods Meta-analysis on studies reported in English and Chinese between 1994 and 2012. Results The pooled prevalence and attribution rates of HPV52 and HPV58 in invasive cervical cancers were significantly higher in Eastern Asia compared to other regions (HPV52 prevalence: 5.7% vs. 1.8–3.6%, P<0.001; HPV52 attribution: 3.7% vs. 0.2–2.0%; HPV58 prevalence: 9.8% vs. 1.1–2.5%, P<0.001; HPV58 attribution: 6.4% vs. 0.7–2.2%, P<0.001). Oceania has an insufficient number of studies to ascertain the prevalence of HPV52. Within Eastern Asia, the attribution of HPV58 to invasive cervical cancer was 1.8-fold higher than that of HPV52. Similarly, HPV52 and HPV58 shared a higher prevalence and attribution among cervical intraepithelial neoplasia in Eastern Asia. In contrast to the classical high-risk type, HPV16, the prevalence and attribution of HPV52 and HPV58 decreased with increasing lesion severity. Thus, HPV52 and HPV58 behave as an “intermediate-risk” type. Conclusion The attribution of HPV52 and HPV58 to cervical intraepithelial neoplasia and invasive cancer in Eastern Asia were respectively 2.5–2.8 and 3.7–4.9 folds higher than elsewhere. Changes in the attributed disease fraction can serve as a surrogate marker for cross-protection or type replacement following widespread use of HPV16/18-based vaccines. This unique epidemiology should be considered when designing HPV screening assays and vaccines for Eastern Asia.

Abstract
Human papillomavirus (HPV) is a major cause of cervical cancer. More than 100 HPV genotypes have been identified; however the distribution varies geographically and according to ethnicity. The purpose of this study was to investigate the prevalence and distribution of HPV subtypes among Northeast Thai women. Subjects included 198 cases of SCCA and 198 age-matched, healthy controls. HPV-DNA was amplified by PCR using the consensus primers GP5+/6+ system followed by reverse line blot hybridization genotyping. The prevalence of high-risk HPV infection was 21 (10.1%) and 152 (76.8%) in the controls and in the cases, respectively. High-risk HPV significantly increased the risk for cervical cancer with an OR of 42.4 (95%CI: 22.4-81.4, p<0.001) and an adjusted OR of 40.7-fold (95%CI: 21.5-76.8, p <0.001). HPV-16 was the most prevalent HPV type in the SCCA (56.2%) followed by HPV-58 (17.8%) and HPV-18 (13.6%); whereas HPV-58 (46.4%) was a prominent genotype in the controls followed by HPV-16 (39.3%) and unidentified HPV types (25.0%). These findings indicate that HPV infection remains a critical risk factor for SCCA; particularly, HPV-16, HPV-58 and HPV-18. In order to eradicate cervical cancer, sustained health education, promoted use of prophylactics and a HPV-58 vaccine should be introduced in this region.

Abstract
Human papillomavirus (HPV) genotype 52 is commonly found in Asian cases of cervical cancer but is rare elsewhere. Analysis of 611 isolates collected worldwide revealed a remarkable geographical distribution, with lineage B predominating in Asia (89.0% vs 0%-5.5%; P(corrected) < .001), whereas lineage A predominated in Africa, the Americas, and Europe. We propose that the name "Asian lineage" be used to denote lineage B, to signify this feature. Preliminary analysis suggested a higher disease risk for lineage B, although ethnogeographical confounders could not be excluded. Further studies are warranted to verify whether the reported high attribution of disease to HPV52 in Asia is due to the high prevalence of lineage B.

Abstract
Background This study investigates the prevalence of human papillomavirus (HPV) 52 and 58 genotypes among women residing in Busan, and the expression of p16 and p53 proteins in cervical neoplasia with HPV 52 and 58 infections. Methods A total of three hundred fifteen cases were analyzed using the HPV DNA chip test for HPV genotypes, and of these, we retrospectively examined p16 and p53 expression in 62 cases of cervical tissues infected with HPV 52 and 58 using immunohistochemistry. Results HPV 52 and 58 genotypes were identified in 62 (54.9%) out of 113 high-risk, HPV-infected cases. Of the cases examined, there were 19 single HPV 52 infections (16.8%), 23 single HPV 58 infections (20.4%), 4 multiple HPV 52 infections (3.5%), and 16 multiple HPV-58 infections (14.2%). Immunoreactivity of p16 and p53 was observed in 41 (66.1%) and 23 (37.1%) of the 62 cases of cervical neoplasia infected with HPV 52 and 58 genotypes, respectively. Conclusions This study demonstrates a high prevalence of HPV 52 and 58 genotypes, in addition to HPV 16, among high-risk strains of cervical neoplasia in Korea. These findings suggest that development of more vaccines would be beneficial for the prevention of the various HPV genotypes.

Abstract
Purpose Cervical cytology and human papillomavirus (HPV) DNA co-testing is recommended as a screening method for detecting cervical lesions. However, for women who are HPV-positive but cytology-negative, the appropriate management and significance of HPV-58 infection remain unknown. Methods This study of prevalent HPV detected at baseline with a median follow-up of 3.2 years evaluated the risk factors associated with cervical abnormalities and assessed the significance of HPV-58 infection. A total of 265 women were enrolled. All high-grade squamous intraepithelial lesions (HSIL) that were detected by cytology were confirmed by histology. Histological diagnoses of cervical intraepithelial neoplasia 2/3 were classified as HSIL. Women were classified into four groups according to the HPV genotype that was detected at their first visit: HPV-58 (n = 27), HPV-16 (n = 52; 3 women had HPV-58 co-infection), ten other high risk (HR) types (n = 79), or low/undetermined risk types (n = 107). Results Of 265 women, 20 (7.5%) had HSIL on their follow-up examinations. There were significant differences in the cumulative incidence of HSIL between the four groups (p<0.001). The 5-year cumulative incidence rates of HSIL were 34.0% (95% CI: 17.3–59.8%) in HPV-58 positive cases, 28.0% (95% CI: 13.8–51.6) in HPV-16 positive cases, 5.5% (95% CI: 2.1–14.0%) in one of the ten other types of HR-HPV positive cases, and 0% in women with low/undetermined risk HPV. When seen in women with HR-HPV (n = 158), persistent HPV infection was a significant factor associated with the development of HSIL (hazard ratio = 15.459, 95% CI: 2.042–117.045). Women with HPV-58 had a higher risk (hazard ratio = 5.260, 95% CI: 1.538–17.987) for the development of HSIL than women with HPV-16 (hazard ratio = 3.822, 95% CI: 1.176–12.424) in comparison with women with other types of HR-HPV. Conclusion HPV-58 has a high association with the development of HSIL in women who are HPV-positive and cytology-negative.

Abstract
HPV 58 is detected commonly in cervical cancer in East Asian countries. To evaluate the HPV 58 physical state, the amplification of papillomavirus oncogene transcripts (APOT) and hybridisation assays were established. Episome- and integrate-derived transcripts were confirmed by direct sequencing. Twenty-nine HPV 58 positive samples from various cervical lesions were used. The results showed that the episome-derived transcripts were recognised as two major specific amplified products (1040 and 714 bp). Two splice donor sites were mapped to the 5' splice site of the E1 gene on SD898 and SD899 and spliced to the 3' acceptor site of the E4 gene on SA3353, SA3356 and SA3365. The episome-derived transcripts were found 100% in normal cervical epithelia and low-grade lesions (9/9 cases) while the integrate-derived transcripts were detected in 13.3% of high-grade lesions (2/15 cases) and in 20% of carcinomas (1/5 cases). HPV 58 integration sites were found on chromosomes 4q21, 12q24 and 18q12. Using the established APOT assay, the results revealed not only novel information on the HPV 58 transcription patterns of episomal transcripts, but also integration site. The APOT assay is a reliable and useful tool for the detection of the HPV 58 physical state and its oncogene expression.

Abstract
HPV account for most of the incidence of cervical cancer. Approximately 90% of anal cancers and a smaller subset (<50%) of other cancers (oropharyngeal, penile, vaginal, vulvar) are also attributed to HPV. The L1 protein comprising HPV vaccine formulations elicits high-titre neutralizing antibodies and confers type restricted protection. The L2 protein is a promising candidate for a broadly protective HPV vaccine. In our previous study, we found the most prevalent high-risk HPV infectious serotypes were HPV-16 and HPV-58 among women of Southwest China. To explore gene polymorphisms and intratypic variations of HPV-16 and HPV-58 L1/L2 genes originating in Southwest China, HPV-16 (L1: n = 31, L2: n = 28) and HPV-58 (L1: n = 21, L2: n = 21) L1/L2 genes were sequenced and compared to others described and submitted to GenBank. Phylogenetic trees were then constructed by Neighbor-Joining and the Kimura 2-parameters methods (MEGA software), followed by an analysis of the diversity of secondary structure. Then selection pressures acting on the L1/L2 genes were estimated by PAML software. Twenty-nine single nucleotide changes were observed in HPV-16 L1 sequences with 16/29 non-synonymous mutations and 13/29 synonymous mutations (six in alpha helix and two in beta turns). Seventeen single nucleotide changes were observed in HPV-16 L2 sequences with 8/17 non-synonymous mutations (one in beta turn) and 9/17 synonymous mutations. Twenty-four single nucleotide changes were observed in HPV-58 L1 sequences with 10/24 non-synonymous mutations and 14/24 synonymous mutations (eight in alpha helix and four in beta turn). Seven single nucleotide changes were observed in HPV-58 L2 sequences with 4/7 non-synonymous mutations and 3/7 synonymous mutations. The result of selective pressure analysis showed that most of these mutations were of positive selection. This study may help understand the intrinsic geographical relatedness and biological differences of HPV-16/HPV-58 and contributes further to research on their infectivity, pathogenicity, and vaccine strategy.

Abstract
Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were examined. Phylogenetic relationship, geographical distribution and risk association of nucleotide sequence variations were analyzed. We found that the E6 genes of HPV58 variants were more conserved than E7. Thus, E6 is a more appropriate target for type-specific detection, whereas E7 is more appropriate for strain differentiation. The frequency of sequence variation varied geographically. Africa had significantly more isolates with E6-367A (D86E) but significantly less isolates with E6-203G, -245G, -367C (prototype-like) than other regions (p ≤ 0.003). E7-632T, -760A (T20I, G63S) was more frequently found in Asia, and E7-793G (T74A) was more frequent in Africa (p < 0.001). Variants with T20I and G63S substitutions at E7 conferred a significantly higher risk for cervical intraepithelial neoplasia grade III and invasive cervical cancer compared to other HPV58 variants (odds ratio = 4.44, p = 0.007). In conclusion, T20I and/or G63S substitution(s) at E7 of HPV58 is/are associated with a higher risk for cervical neoplasia. These substitutions are more commonly found in Asia and the Americas, which may account for the higher disease attribution of HPV58 in these areas.

Abstract
The E6 and E7 proteins encoded by human papillomaviruses (HPV) are prime targets for therapeutic vaccine development. Ninety-five women with HPV 52 infection (33 transient infections, 17 cervical intraepithelial neoplasia grade II, 15 cervical intraepithelial neoplasia grade III, and 30 invasive cervical cancers) were examined for T-cell responses using interferon-γ enzyme-linked immunospot (IFN-γ ELISPOT) assay. Of the 29 peptides (13 L1, 10 E6, and 6 E7) screened positive by an in vitro peptide-binding assay, 14 were positive by the IFN-γ ELISPOT assay. Positive epitopes for HLA A11 were located at amino acid positions 103-111, 332-340, 342-350, and 373-381 of the L1 protein; and at 27-35 and 86-94 of the E6 protein; and at 1-9 and 27-35 of the E7 protein. A24-specific epitopes included 60-68 and 98-106 of the L1 protein, 42-50 and 59-67 of the E6 protein, and 24-32 of the E7 protein. Only one epitope (99-107) of the E6 protein showed positive responses for HLA A2 subjects. Overall, T-cell responses against L1 were observed mainly in subjects who had cleared infection; whereas responses against E6 and E7 were confined mainly to subjects who had developed cervical neoplasia. The proportion of subjects showing detectable T-cell responses was low across all grades of cervical neoplasia suggesting that immune evasion mechanisms had set on early in the course of disease progression. This study provides the first set of T-cell epitopes mapped for HPV 52, which can be considered for further evaluation as targets for immunotherapy.

Abstract
The development of a prophylactic vaccine that targets human papillomaviruses (HPV) 6, 11, 16, and 18 to prevent cervical cancer has increased interest in the ethnic and geographical distributions of HPV genotypes. We investigated HPV prevalence and type distribution by restriction fragment mass polymorphism (RFMP) testing a total of 60,775 specimens (aged 18-79 yr, median 44) taken from liquid-based cytology. Overall HPV positive rate of total patients was 34.2%. Among the positive patients, 87.7% was single type infections, and 12.3% was multiple HPV types. HPV-16 was the most prevalent genotype observed in 2,307 (26.0%), followed by type 52 in 2,269 (25.5%), type 58 in 1,090 (12.3%), type 18 in 633 (7.1%), type 56 in 436 (4.9%). The pattern of high risk-HPV positive rate according to age showed U-shape with a peak in HPV prevalence among women less than 30 yr of age, and a second peak among the older females aged 70 to 79 yr. The leading four high-risk HPV genotypes were HPV-16, HPV-52, HPV-58, and HPV-18 in descending order. In conclusion, this study provides the most representative prevalence and type-specific distribution of HPV among Korean women, and demonstrates that the epidemiology of HPV infection is different from that of other regions of the world.

Abstract
Human papillomavirus (HPV) infection is associated with a wide spectrum of disease that ranges from self-limited skin warts to life-threatening cancers. Since HPV plays a necessary etiological role in cervical cancer, it is logical to use HPV as a marker for early detection of cervical cancer and precancer. Recent advances in technology enable the development of high-throughput HPV assays of different formats, including DNA-based, mRNA-based, high-risk group-specific and type-specific methods. The ultimate goal of these assays is to improve the accuracy and cost-effectiveness of cervical screening programs. HPV testing has several potential advantages compared to cytology-based screening. However, since the cancer to transient infection ratio is always low in the general population, HPV test results are bound to have a low positive predictive value that may subject women to unnecessary follow-up investigations. The wide-spread administration of prophylactic HPV vaccine will substantially decrease the incidence of cancer and precancer. This poses a number of challenges to cytology-based screening, and the role of HPV testing is expected to increase. Finally, apart from technical and cost-effectiveness considerations, one should also keep in mind the psycho-social impact of using sexually-transmitted agents as a marker for cancer screening.

Abstract
Background About 15 types of human papillomavirus (HPV) are classified as high-risk based on their epidemiological link with cervical cancer. These HPV types have deferent degrees of oncogenicity and their distribution among cervical precancers and cancers varies ethnogeographically. HPV58 is rare worldwide but being found more commonly in East Asia. Findings A high prevalence of HPV58 among squamous cell carcinoma has been reported from China (28% in Shanghai, 10% in Hong Kong and 10% in Taiwan) and other countries in East Asia including Korea (16%) and Japan (8%). HPV58 ranks the third in Asia overall, but contributes to only 3.3% of cervical cancers globally. The reasons for a difference in disease attribution may lie on the host as well as the virus itself. HLA-DQB1*06 was found to associate with a higher risk of developing HPV58-positive cervical neoplasia in Hong Kong women, but not neoplasia caused by other HPV types. An HPV58 variant (E7 T20I, G63S) commonly detected in Hong Kong was found to confer a 6.9-fold higher risk of developing cervical cancer compared to other variants. A study involving 15 countries/cities has shown a predilection in the distribution of HPV58 variant lineages. Sublineage A1, the prototype derived from a cancer patient in Japan, was rare worldwide except in Asia. Conclusions HPV58 accounts for a larger share of disease burden in East Asia, which may be a result of differences in host genetics as well as the oncogenicity of circulating variants. These unique characteristics of HPV58 should be considered in the development of next generation vaccines and diagnostic assays.

Oral administration of HPV-16 L2 displayed on Lactobacillus casei induces systematic and mucosal cross-neutralizing effects in Balb/c mice. Vaccine 2012; 30:3286-94.

Abstract
The human papillomavirus (HPV) minor capsid protein, L2, is a good candidate for prophylactic vaccine development because L2-specific antibodies have cross-neutralizing activity against diverse HPV types. Here, we developed a HPV mucosal vaccine candidate using the poly-γ-glutamic acid synthetase A (pgsA) protein to display a partial HPV-16 L2 protein (N-terminal 1-224 amino acid) on the surface of Lactobacillus casei (L. casei). The oral immunization with L. casei-L2 induced productions of L2-specific serum IgG and vaginal IgG and IgA in Balb/c mice. To examine cross-neutralizing activity, we used a sensitive high-throughput neutralization assay based on HPV-16, -18, -45, -58, and bovine papillomavirus 1 (BPV1) pseudovirions. Our results revealed that mice vaccinated with L. casei-L2 not only generated neutralizing antibodies against HPV-16, but they also produced antibodies capable of cross-neutralizing the HPV-18, -45, and -58 pseudovirions. Consistent with previous reports, vaccination with HPV-16 L1 virus-like particles (VLPs) failed to show cross-neutralizing activity. Finally, we found that oral administration of L. casei-L2 induced significant neutralizing activities against genital infection by HPV-16, -18, -45, and -58 pseudovirions encoding a fluorescence reporter gene. These results collectively indicate that oral administration of L2 displayed on L. casei induces systemic and mucosal cross-neutralizing effects in mice.

Abstract
BACKGROUND Human papillomavirus type 58 (HPV-58) accounts for a much higher proportion of cervical cancers in East Asia than other types. A classification system of HPV-58, which is essential for molecular epidemiological study, is lacking. METHODS AND RESULTS This study analyzed the sequences of 401 isolates collected from 15 countries and cities. The 268 unique concatenated E6-E7-E2-E5-L1-LCR sequences that comprised 57% of the whole HPV-58 genome showed 4 distinct clusters. L1 and LCR produced tree topologies that best resembled the concatenated sequences and thus are the most appropriate surrogate regions for lineage classification. Moreover, short fragments from L1 (nucleotides 6014-6539) and LCR (nucleotides 7257-7429 and 7540-52) were found to contain sequence signatures informative for lineage identification. Lineage A was the most prevalent lineage across all regions. Lineage C was more frequent in Africa than elsewhere, whereas lineage D was more prevalent in Africa than in Asia. Among lineage A variants, sublineage A2 dominated in Africa, the Americas, and Europe, but not in Asia. Sublineage A1, which represents the prototype that originated from a patient with cancer, was rare worldwide except in Asia. CONCLUSIONS HPV-58 can be classified into 4 lineages that show some degree of ethnogeographic predilection in distribution. The evolutionary, epidemiological, and pathological characteristics of these lineages warrant further study.

Abstract
A prospective, cross-sectional study was conducted to investigate the correlation between the integration of high-risk human papillomavirus and disease severity of cervical lesions. 720 liquid-based cytology specimens including 422 normal cytology, 78 low-grade squamous intraepithelial lesions, 172 high-grade squamous intraepithelial lesions, and 48 women with cervical cancers were examined using HPV blot and type-specific E6 PCR. Positive HPV DNA types 16, 18, 52 and 58 were examined for viral DNA using real-time PCR. Expression of E6 transcripts was 89.5% (pure integration), 71.7% (mixed type), and 47.1% (pure episomal) (p<0.0001). Geometric mean levels ranged from 110.6 (episomal form) to 508.4 (mixed form), and 5966.2 (integration form) by real-time PCR (p<0.0001). Geometric mean levels of E6 transcript in HPV 16, 18, 52, and 58 correlated with the severity of cervical lesions and the physical integration state of the viral genome (p<0.0001). We conclude that this is the first paper to point out that integration of high-risk HPVs not only 16 and 18 but also 52 and 58 is correlated with high levels of oncogene transcripts from normal cervix, CIN to cervical cancer.

Abstract
OBJECTIVES Human papillomavirus (HPV) type 58 is the second most prevalent virus infection among Chinese women. To develop an HPV58 vaccine that combines both prophylactic and therapeutic functions, we generate a chimeric virus-like particle (cVLP). METHODS The cVLPs contain both whole length L1 and parts of E7 peptides either from E7 amino acids (aa) 50 to aa72 or from E7 aa4 to aa12. The HPV58 L1-E7aa50-72 and L1-E7aa4-12 fusion proteins were revealed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and confirmed by Western blot (Supplementary Digital Content 1, http://links.lww.com/IGC/A40, which shows alignment of the protein sequence between HPV58 L1-E7aa50-72/4-12 and standard sequence). Protein folding and location of cVLPs were identified by transmission electron microscope. The immunogenicity of the fusion protein was tested by enzyme-linked immunospot assay. RESULTS Transmission electron microscope showed that the fusion protein formed cVLPs by self-assembly and the majority of particles located in the nucleus of the sf-9 insect cells. The cVLPs displayed a strong ability to agglutinate erythrocytes, which is distinguished from the parental VLPs. In addition, the purified HPV58 L1-E7aa50-72 or L1-E7aa4-12 fusion protein induced significant numbers of interferon γ-expressing E7aa50-72- or E7aa4-12-specific CD8 T cells. DISCUSSION Our results indicate that the insertion of the E7aa50-72 or E7aa4-12 peptides behind L1 did not disrupt the assembly of cVLPs and provided potent immunogenicity and bioactivity, which created a powerful basis for further preparations of HPV58 vaccines with prophylactic and therapeutic effects for the treatment of HPV58-related diseases including cervical cancer.

Abstract
In order to determine the prevalence and genotype distribution of human papillomavirus (HPV) infection in patients with nasal polyps, a total of 204 patients with nasal polyps and 36 healthy controls were recruited for this study. Genomic DNA was extracted from paraffin-embedded tissue sections. HPV DNA genotyping was achieved by a flow-through hybridization and gene-chip method. HPV-positive infection was identified in 82 of 204 (40.2 %) patients, while HPV DNA was not found in healthy controls (P<0.05). Genotyping analysis showed that low-risk HPV genotype 11 was the most prevalent type of HPV in nasal polyps (45.28 %). Both single and multiple HPV genotype infections were found in these HPV-positive cases, although most (74.39 %) were infected with a single genotype. In addition, there was no correlation between HPV infection or HPV subtypes and the clinicopathological characteristics of patients, such as age, gender, number of surgery and disease course. The data from our study clearly demonstrated that HPV infection was associated with nasal polyps. Both high-risk HPV and low-risk HPV (LR-HPV) genotypes were identified in nasal polyp tissues, and LR-HPV-11 was the most prevalent type. Future research will explore the association of HPV infection with the development and progression of nasal polyps.

We aimed to assess the distribution of human papillomavirus (HPV) genotypes in high-grade cervical lesions in Taiwan. The study included 1,086 paraffin-embedded, formaldehyde-fixed cervical intraepithelial neoplasia (CIN) 2/3 specimens. HPV genotyping was performed using polymerase chain reaction (PCR)-based methods. Multiple HPV types were validated by E6 type-specific PCR, direct sequencing and/or real-time PCR. HPV DNA was detected in 995 (91.6%) specimens, and multiple HPV types were identified in 192 (19.3%) samples. The leading HPV types were HPV16 (24%), HPV52 (20%), HPV58 (20%), HPV33 (13%), HPV31 (8%) and HPV18 (4.6%). Although the leading six types consisted of 87.6%, HPV16 or 18 comprised only 30.9%. The prevalence of different HPV types showed a significant association with age. In women older than 50 yr, HPV16 and 18 comprised 21.3% (83/389), while HPV52, 58 and 33 represented 55.5% (216/389). In women aged less than 50 yr, HPV16 and 18 comprised 32.1% (224/697, p < 0.0001), while HPV 52, 58 and 33 represented 47.9% (334/697, p = 0.02). The distribution of HPV genotypes was compared with previously reported findings for Taiwanese women with cervical cancer (CC). The overall HPV16 positivity rate was significantly higher in CC than in CIN 2/3 (odds ratio: 2.14, 95% CI: 1.91-2.40). In addition, HPV18, 39 and 45 were significantly overrepresented in CC, whereas HPV52, 58, 33, 31, 35, 51 and 53 were underrepresented. We concluded that an effective vaccine against the most common HPV types could prevent a significant proportion of cervical cancer cases that occur in Taiwan.
