[PMID: 39628831 PMCID: PMC11613703 DOI: 10.2147/idr.s484519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2024] [Accepted: 11/22/2024] [Indexed: 12/06/2024] Open
Abstract
Objective This study aimed to investigate the infection rate, types of human papillomavirus (HPV), and the relationship between HPV types and host factors in Zhejiang and lay a foundation for developing a prophylactic HPV vaccine. Methods A retrospective analysis of the genotyping results of 27 hPV types using exfoliated cells from the cervix, vulva, perianal region, or oral mucosa of 28206 females, and exfoliated cells from the penis, perianal region or oral mucosa of 2923 male patients undergoing treatment between January 2016 and December 2021 at Zhejiang Provincial People's Hospital was performed. Results In females, the overall positive rate was 30.26%. The top five HPV types were HPV52, 58, 16, 6, and 53. In males, the overall positive rate was 31.85%. The top five HPV types were HPV6, 11, 16, 52, and 43. About 90.48% of patients with CINII+ were HR-HPV+. HPV33, 16 were the top two HPV types that increased CINII+ risks. Conclusion Currently, the bivalent (HPV16, 18), quadrivalent (HPV6, 11, 16, 18), and 9-valent (HPV6, 11, 16, 18, 31, 33, 45, 52, 58) HPV vaccines are marketed. Of these, the 9-valent HPV vaccines are more suitable for people in the Zhejiang province; however, it is still insufficient. Therefore, the 11-, 14-, and 15-valent vaccines being developed and marketed include more genotypes, and their outcomes are worth anticipating.

Abstract
Background Cervical cancer is primarily caused by HPV infection. The epidemiology of HPV infection in specific areas is of great meaning of guide cervical cancer screening and formulating HPV vaccination strategies. Here, we evaluated the epidemiological characteristics of HPV infection in Xiamen population. Methods In total, 159,049 cervical exfoliated cell samples collected from female outpatients in Women and Children's Hospital, School of Medicine, Xiamen between January 2013 and July 2023 were analyzed. HPV DNA detection was performed using HPV genotyping kits (Hybribio Limited Corp, China). An analysis was conducted on the prevalence of HPV infection, taking into account factors such as age, year, and multiple patterns of HPV infection. The differences in prevalence among age groups and years were compared using χ2 test. Results The overall prevalence of any 21 HPV genotypes was 18.4%, of which the high-risk HPV (HR-HPV) positive rate was 14.6%. The age-specific prevalence of HPV infection showed a bimodal distribution, with two distinct peaks, one at <25 years (31.2%) and the other at 60-64 years (32.9%). There was a downward trend in the prevalence of HPV infection over time, decreasing from 26.2% in 2013 to 14.5% in 2021, and then increasing to 19.0% in 2023. The five most prevent HR-HPV genotypes were HPV52 (4.0%), 58 (2.6%), 16 (2.5%), 51 (1.8%), and 39 (1.7%). Among the positive cases, 76.7% were detected with only one genotype and 23.3% with multiple genotypes. The most common co-infection was HPV52 + HPV58 (0.24%), followed by HPV16 + HPV52 (0.24%), HPV52 + HPV53 (0.21%), HPV52 + HPV81 (0.21%), HPV51 + HPV52 (0.19%), HPV16 + HPV58 (0.18%), and HPV39 + HPV52 (0.17%). Conclusion The study provided the largest scale information on the recent epidemiological characteristics of HPV infection in Xiamen, and even in Fujian Province, China, which would support making the prevention and control strategies for cervical cancer in the region.

Abstract
OBJECTIVE The persistence of HPV infection is a significant etiological factor in the development of cervical cancer. The present study investigated the prevalence and genotype distribution of human papillomavirus (HPV) in a cohort of 164,137 unvaccinated women from Wenzhou, aiming to provide guidance for clinics in the cervical cancer screening and HPV vaccination strategies. METHODS The present retrospective study included a total of 164,137 women, comprising 118,484 outpatients and 45,653 healthy female subjects recruited from 2015 to 2020. Cervical exfoliated cells were collected from these participants for subsequent DNA extraction. The extracted DNA samples were underwent analysis using a fluorescence in situ hybridization method, encompassing the detection of 27 HPV genotypes. RESULTS The overall prevalence of HPV was 17.35%; this corresponded to a prevalence of 19.10% in the outpatient group and 12.82% in the healthy female group. Among the outpatient group, the five most prevalent HPV genotypes were identified as HPV 52, 58, 16, 53, and 61. In the healthy female group, the five most common HPV genotypes were found to be HPV 52, 53, 58, 61, and 81. Additionally, it was estimated that the highest rate of HPV infection occurred among individuals aged between 10 and 19 years old (44.65%) and those aged between 60 and 69 years old (27.35%). CONCLUSIONS The prevalence of HPV in this region is substantial; therefore, it is imperative to implement scientifically sound and rational clinical interventions such as vaccination. Routine cervical screening should be performed to prevent the development of cervical intraepithelial neoplasia resulting from persistent infection with high-risk HPV, particularly in women with gynecological diseases and those over 60 years old.

Mol Cell Probes 2021; 61:101787. [PMID: 34875349 DOI: 10.1016/j.mcp.2021.101787] [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: 07/01/2021] [Revised: 11/29/2021] [Accepted: 12/02/2021] [Indexed: 12/24/2022]
Abstract
Current human papillomavirus (HPV) detection methods require complex instruments, skilled staff and have a high cost. Therefore, novel testing approaches are needed which are easy to implement, highly sensitive, and low cost. Loop-mediated isothermal amplification (LAMP) is an isothermal amplification technique. In this study, according to the conditions in China, a novel LAMP method for detecting seven high-risk HPV subtypes (16, 18, 33, 39, 45, 52, and 58) was designed and evaluated. The DNA from plasmid and cervical specimens was extracted using Chelex 100 and measured by qPCR and LAMP assay. LAMP products were observed under ultraviolet light. HPV sequences were successfully amplified and a plateau time of 19-75 min was maintained. The concentration of positive reactions ranged between 20 copies/μL and 200000 copies/μL. Additionally, there was no cross-reactivity between HPV16, 18, 33, 39, 45, 52, 58, 31, 35, 45, 51, 56, 59, 66, or 68. For clinical samples, the LAMP assay had high sensitivity and specificity for HPV16, 18, 33, 39, 45, 52, and 58. However, 5% (72/1447) of the samples tested yielded false-positive results. In conclusion, the novel LAMP assay for HPV16, 18, 33, 39, 45, 52, and 58 has high sensitivity and specificity, a low cost, and is simple and rapid to perform. The LAMP assay can improve HPV detection in resource-limited settings, especially in primary care hospitals and rural areas.

Abstract
Cervical cancer is the fourth most common cancer among women worldwide in terms of both incidence and mortality. Persistent infection with high-risk human papillomavirus (HPV) has been identified as a cause of cervical intraepithelial neoplasia and invasive cervical cancer. The distribution of human papillomavirus genotypes varies regionally. To acquire baseline data on the population-based prevalence and genotype distribution of HPV infection, we investigated the molecular epidemiology of HPV infection among women in Xi'an, China. The study was conducted from September 2018 to December 2020. A total of 14,655 women aged 30-65 years were screened. The overall prevalence of HPV infection was 13.5% (95% confidence interval [CI]: 13.0-14.1%), with 10.4% of participants being positive for a single HPV type and 3.1% being positive for multiple HPV types. The prevalence of high-risk HPV (HR-HPV), low-risk HPV (LR-HPV) and mixed HPV infection was 10.1% (95% CI: 9.6-10.5%), 2.2% (95% CI: 2.0-2.4%), and 1.3% (95% CI: 1.1-1.5%), respectively. The five most frequently detected HR-HPV types were types 52 (2.6%), 16 (1.9%), 53 (1.8%), 58 (1.4%), and 51 (0.9%). The most frequently detected LR-HPV type was HPV-42 (1.1%). The prevalence and HPV genotype distribution varied by region and age. Age-specific HPV prevalence peaked in the over 60 years age group (18.8%), and Beilin District had the highest HPV prevalence (18.1%). The results of this first population-based study provide a reference for HPV-based cervical cancer screening and HPV vaccination programs in Xi'an.

Abstract
Human papillomavirus (HPV) infection has a key role in the development of cervical cancer. The present study aimed to determine the HPV type distribution among females of Uyghur ethnicity in Xinjiang province, northwest China. A total of 12,165 individuals aged 30-79 years from 12 villages in Zepu County, Kashgar Prefecture, Xinjiang province were recruited for screening. Cervical and vaginal swabs from each subject were collected by gynecologists and tested for HPV DNA using Luminex xMAP technology. The results indicated that the overall HPV prevalence was 9.34% (1,136/12,165) in the present cohort; 7.41% (901/12,165) of the individuals were positive for high-risk type HPV (HR-HPV) and 1.64% (200/12,165) were positive for multiple types. Among the individuals who tested positive for HR-HPV types, the three most prevalent types were HPV16 (2.83%), HPV31 (0.99%) and HPV68 (0.88%). Subgroup analysis by age indicated that the highest frequency of HPV infections occurred in subjects aged >60 years. The most common genotype combinations in subjects with multiple types were HPV16 + HPV54, HPV16 + HPV31 and HPV16 + HPV68. The present study provided data on the prevalence and type distribution of HPV infections among Uyghur females in Xinjiang province, northwestern China, which will assist in the assessment of the potential cost-effectiveness of HPV screening and vaccination in this population. The data will also facilitate the determination of HPV68 and 54 strains that should be included in the multi-type vaccine and the establishment of a vaccination program that caters for the different age groups of the Uyghur population.

Multi-Infection Patterns and Co-infection Preference of 27 Human Papillomavirus Types Among 137,943 Gynecological Outpatients Across China. Front Oncol 2020; 10:449. [PMID: 32318343 PMCID: PMC7154087 DOI: 10.3389/fonc.2020.00449] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Accepted: 03/13/2020] [Indexed: 12/24/2022] Open
Abstract
Background: The epidemiological feature of human papillomavirus (HPV) infection is distinctive in China. We aimed to investigate the multi-infection patterns and co-infection preference of 27 HPV types among gynecological outpatients across China. Methods: Overall 137,943 gynecological outpatients were recruited from eight tertiary hospitals located in seven regions of China, between July 1st, 2014 and December 31st, 2016. The overall, region-specific, age-specific and type-specific prevalence of HPV infection were calculated, respectively. The pattern of HPV infection was also evaluated. Furthermore, rate ratio was calculated to evaluate the co-infection preference of any two HPV genotypes. Results: The overall prevalence of 27 HPVs' [17 high-risk (hr)/10 low-risk (lr)] infection was 23.5%. The age-specific HPV prevalence showed a “U-shaped” pattern. The most prevalent hrHPV genotypes were 16, 52, and 58. Multiple infections were detected in 25.8% of the HPV-positive women, in which dual infection was more prevalent. HPV 16/18 were likely to co-infected with HPV 31 but unlikely with HPV 52/58, i.e., the co-infection of HPV 16 with HPV 31 was high (3.5-fold), but low for HPV 58 (1.8-fold), and 52 (1.2-fold), while the co-infection of HPV 18 with HPV 31 was high (4.3-fold), but low for HPV 52 (1.9-fold), and 58 (1.7-fold). Conclusions: We found age-specific prevalence of HPV infection showed a “U-shaped” pattern for high and low risk HPV, suggesting the importance of screening among younger women and the necessary of detection among older women. We found a novel co-infection preference of HPV 16/18 with 31, 52, and 58, suggesting a need of developing and marketing prophylactic HPV vaccines that protect against more genotypes in China.

[PMID: 31109361 PMCID: PMC6528239 DOI: 10.1186/s12985-019-1175-z] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Accepted: 05/06/2019] [Indexed: 11/12/2022] Open
Abstract
Background Human papillomavirus (HPV) infection may lead to a series of lesions in the cervix. Distributions of HPV genotypes reveal that an increased prevalence of high-risk HPV (HR-HPV) is positively correlated with the severity of cervical lesions. Furthermore, persistent infection of HR-HPV is associated with a risk of cervical cancer. Considering the newly approval of the HPV vaccine in China and the prevalence of HPV distribution, which is meaningful for directing efforts for HPV vaccination, a more detailed understanding of HPV distribution is critical. This study aimed to investigate the overall prevalence of HPV and the age-specific features related to HPV distribution in the Jiangsu population. Methods We collected a total of 62,317 cervical cytological specimens from Xuzhou, Nanjing and Suzhou, which represent the northern, middle and southern regions of Jiangsu Province, respectively. All these samples were assigned to 6 groups based on participant age. HPV genotypes tests were performed by using a commercial kit which is designed for the detection of 17 high-risk HPV genotypes and 6 low-risk HPV genotypes. Results The overall prevalence of HPV was up to 26.92% in Jiangsu Province. The most common high-risk genotype was HPV52 (5.09%), followed by HPV16, HPV58, HPV53, HPV51 and HPV68. The most prevalent low-risk genotype was HPV81 (2.70%), followed by HPV43, HPV42, HPV6, HPV11 and HPV83. Most infections were caused by HR-HPV, while single-genotype infection occurred more frequently than multiple-genotype infection. Regarding participant age, the overall infection rate of HPV was distributed in a U-shaped manner, with the highest peak in the younger than 20-year-old cohort. Additionally, significant variations were found between different cities, representing different regions of Jiangsu. Conclusions HPV prevalence is high in Jiangsu Province. The prevention of HPV-related diseases is challenging. Given the variation in HPV prevalence between ages groups and regions, a flexible HPV vaccination program, adjusted base on regional infection features, could have a beneficial effect in Jiangsu Province.

Abstract
Immunomics tools and databases play an important role in the designing of prophylactic or therapeutic vaccines against pathogenic bacteria and viruses. Therefore, we aimed to illustrate the different immunological databases and web servers used to design a chimeric vaccine candidate against human cervix papilloma. Initially, cellular immunity inducing major histocompatibility complex class I and II epitopes from L2 protein of papilloma 58 strain were predicted using the IEDB, NetMHC, and Tepi tools. Then, the overlapped segments from the above analysis were used to calculate efficiency on interferon-gamma and humoral immunity production. In addition, the allergenicity, antigenicity, cross-reactivity with human proteomes, and epitope conservancy of elite segments were determined. The chimeric vaccine candidate (SGD58) was constructed with two different overlapped peptide segments (23–36) and (29–42), adjuvants (flagellin and RS09), two Th epitopes, and amino acid linkers. The results of homology modeling demonstrated that SGD58 have 88.6% of favored regions based on Ramachandran plot. Protein–protein docking with Swarm Dock reveals SGD58 with receptor complex have −54.74 kcal/mol of binding energy with more than 20 interacting residues. Docked complex are stable in 100ns of molecular dynamic simulation. Further, coding sequences of SGD58 also show elevated gene expression in E. coli. In conclusion, SGD58 may prompt vaccine against cervix papilloma. This study provides insight of vaccine design against different pathogenic microbes as well.

Abstract
The human papillomavirus (HPV) 58 is considered to be the second most predominant genotype in cervical cancer incidents in China. HPV type-restriction, non-targeted delivery, and the highcost of existing vaccines necessitate continuing research on the HPV vaccine. We aimed to explore the papillomaviral proteome in order to identify potential candidates for a chimeric vaccine against cervix papilloma using computational immunology and structural vaccinology approaches. Two overlapped epitope segments (23⁻36) and (29⁻42) from the N-terminal region of the HPV58 minor capsid protein L2 are selected as capable of inducing both cellular and humoral immunity. In total, 318 amino acid lengths of the vaccine construct SGD58 contain adjuvants (Flagellin and RS09), two Th epitopes, and linkers. SGD58 is a stable protein that is soluble, antigenic, and non-allergenic. Homology modeling and the structural refinement of the best models of SGD58 and TLR5 found 96.8% and 93.9% favored regions in Rampage, respectively. The docking results demonstrated a HADDOCK score of -62.5 ± 7.6, the binding energy (-30 kcal/mol) and 44 interacting amino acid residues between SGD58-TLR5 complex. The docked complex are stable in 100 ns of simulation. The coding sequences of SGD58 also show elevated gene expression in Escherichia coli with 1.0 codon adaptation index and 59.92% glycine-cysteine content. We conclude that SGD58 may prompt the creation a vaccine against cervix papilloma.

Abstract
Human papillomavirus type 16 (HPV16) is considered to be the primary pathogen related to cervical cancer. The HPV16 E2 protein plays an important role in tumourigenicity of cervical carcinoma. In the current study, we enrolled 121 HPV16-positive cervical cancer patients in the case group and 130 HPV16-positive asymptomatic individuals in the control group, and we investigated the association between HPV16 E2 gene variations and cervical cancer. The HPV16 E2 DNA was amplified and sequenced. We identified two HPV variants (EUR and As) in the control group; the As variant was predominant (68.5%), followed by the EUR variant (31.5%). In the case group, three HPV variants (EUR, As and AA) were observed; the As variant was predominant (72.7%), followed by the EUR variant (22.3%) and the AA variant (5.0%). Our results showed a significant difference in the distribution of the HPV16 variants between the case and control groups (P < 0.05). Moreover, in the HPV16 E2 gene variation analysis, the distribution of sixteen variations was significantly different between the case and control groups (P < 0.05), and all of these variations were present in the AA variant. In the subgroup analysis, the frequency of the T3575G (S274A) variation in the EUR variant was significantly different between the case and control groups (P = 0.029); however, there was no significant difference in the frequency of the variations in the As variant between the case and control groups. Our findings in the current study could provide a better understanding of the relationship between HPV16 variants, E2 gene variations and cervical cancer.

Abstract
Objective: Cervical cancer is one of the most common cancers among women all over the world, and main cause is persistent infection with high risk human papillomavirus (HPV) strains. It has been reported that the distribution and prevalence of HPV types varies by geographical region, so that this is important for prevention by type-specific vaccines. The aim of current study was to determine the genotype distribution of HPV using the INNO-LiPA genotyping assay in Zanjan province, North West Iran. Methods: A total of 112 formalin-fixed paraffin embedded (FFPE) tissue samples from cases of low-grade intraepithelial lesion (LSIL), high-grade intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were collected. The polymerase chain reaction (PCR) was used to amplify DNA for genotyping. Results: Among the 112 samples from females (ranging from 20 to 69 years, mean age 43.8 ± 10.1) tested for HPV DNA, 50 samples were positive. Based on results of genotyping, most common HPV genotypes were HPV18 (48%) followed by HPV-6 (24%), HPV73 (16%), HPV-51(8%), HPV-31(8%), HPV-16 (8%), HPV-56 (4%), HPV-44 (4%). Conclusion: While HPV infection is the major etiological factor for cervical cancer, presence was relatively low in our survey. In the positive cases, however, HPV18 was the most common in line with many other populations. The fact that types vary among different populations must clearly be taken into account in design of vaccines for our country.

Abstract
Human papillomavirus infection plays a key role in the development of cervical cancer. To establish a foundation for HPV-based screening and vaccination programs, we investigated the HPV prevalence and genotypic distributions in Chinese women from Zhejiang Province. Between 2011 and 2015, a total of 961,029 samples from 2021 clinical hospitals were tested HPV genotype by a PCR-based hybridization gene chip assay, and 443,890 samples were evaluated cervical cytology by liquid-based cytology analysis. Our results showed that the positive rate for HPV was 20.54%, which ranged from 28.72% to 17.81% and varied by year of recruitment. Age-specific prevalence showed a "two-peak" pattern, with the ≤20-year-old group presenting the highest HPV infection rate, followed by 61-70-year-old group. Overall, the most prevalent genotypes were HPV16, 52 and 58. Additionally, the odds ratios for the prevalence of the HR-HPV, LR-HPV and HPV-negative groups with abnormal cytology were 12.56, 3.21 and 0.06, respectively. Among genotypes, HPV 16 has been found to have the highest OR, followed by HPV58, 18, 52. Here, we present data regarding the prevalence and type distribution of HPV infection, which can serve as valuable reference to guide nationwide cervical cancer screening and HPV vaccination programs.

Abstract
Cervical cancer is the third most common cancer in women worldwide. Human papillomavirus (HPV) has been identified as an etiological factor for cervical cancer. Data on the prevalence and subtype distribution of HPV infection in Jiangxi Province are incomplete. In this study, we investigated HPV subtype distribution and prevalence in Jiangxi Province between August 1, 2010, and December 31, 2015. A total of 71,435 individuals ranging in age from 16 to 77 years were recruited. Cervicovaginal swabs were collected from each participant, and HPV screening was performed. Our results showed that the HPV prevalence was 22.49% in Jiangxi Province. Overall, 14.99% of individuals were positive for a single HPV type, and 7.49% were positive for multiple types. The most frequently detected low-risk genotypes were HPV-6, and high-risk genotypes were HPV-16, -18, -33, -52, and -58. The prevalence and type distribution of HPV infection exhibits regional and age differences; Yingtan had the highest incidence for high-risk HPV infection (32.00%), and peaks in the frequencies of HPV infections were seen for patients under 20 and over 60 years of age. In conclusion, we present data showing that the HPV prevalence varies significantly with age and regions in Jiangxi Province. These results can serve as valuable reference to guide Jiangxi cervical cancer screening and HPV vaccination programs.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the main etiological factor for the development of cervical cancer. Here we assessed the prevalence and distribution of HPV genotypes in Fujian population. METHODS A total of 8678 women aging from 17 to 84 years olds were recruited from the Fujian Medical University Union Hospital in Fujian Province. Every woman had a face-to-face interview. Cervical samples were collected from each participant and HPV screening was conducted using microarray hybridization. RESULTS Our study showed that the HPV prevalence in Fujian province was 38.3%. Among the positive individuals, 70.6% were detected for single HPV infection, 29.4% for multiple HPV infections. Further analysis showed that the prevalence of HPV infection significantly increased from 2009 to 2015. The four most common high risk human papillomavirus (HR-HPV) genotypes were HPV16 (8.5%), HPV52 (7.9%), HPV58 (6.2%), HPV 53 (3.5%), collectively accounting for 60.5% of all detected HPV infection. Age subgroup analysis showed two peaks for the frequencies of overall and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 55 years old. CONCLUSIONS HPV infection is becoming serious in Fujian province, which indicates the imperative to implement a HPV vaccination and screening program for this region.

Abstract
Human papillomavirus (HPV) is the primary infectious agent for the development of cervical cancer, although the presence of the virus alone is insufficient for viral development and proliferation; this can be attributed to the increase in potential oncogenic risk, along with other risk factors. In the present investigation, the prevalence of high-risk HPV was determined from samples of premalignant or malignant cervical cytology in women from the southern region of Ecuador. The kit we used was able to detect genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59. In addition, 64.5% of the analyzed samples were positive for HPV, with genotypes 16 and 18 being the most prevalent (16 was detected in 148 samples and 18 in 108). Genotypes 58 and 51 were the third most frequent simple and multiple infections, respectively. The data are very similar to those obtained worldwide, suggesting that the strategy of sex education, and the use of vaccines as primary prevention agents, could significantly decrease the incidence and mortality rate of cervical cancer in the southern region of Ecuador.

Abstract
Human papillomavirus (HPV) infection plays a key role in the development of cervical cancer. The aim of the current study was to investigate the HPV type distribution in Chinese women from Yunnan Province, southwest China. A total of 28,457 individuals ranging in age from 17-84 years were recruited from 13 clinical hospitals located in 10 different regions of Yunnan Province. Cervicovaginal swabs were collected from each participant, and HPV screening was performed using Luminex xMAP technology. Our results showed that the HPV prevalence was 12.9% in Yunnan Province. Overall, 10.6% of the individuals were positive for a single HPV type, and 2.3% were positive for multiple types. Among the individuals who tested positive for a single HPV type and multiple HPV types, the three most prevalent high-risk types were 52, 16, and 58. Age subgroup analysis showed two peaks for the frequencies of single and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 56 years old. Here, we present data regarding the prevalence and type distribution of HPV infection, which will aid in the estimation of the potential clinical benefit and cost-effectiveness of HPV screening and vaccination in China.

Abstract
PURPOSE The study was designed to: (1) investigate the prevalence of high-risk human papillomavirus (HR- HPV) infection and cervical neoplasia; and (2) evaluate clinical performance of visual inspection with acetic acid/ Lugol's iodine (VIA /VILI), Pap smear, high-risk human papillomavirus (HR-HPV) DNA test for detecting cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and (3) explore appropriate screening approach in rural areas of Shandong Province. MATERIALS AND METHODS A total of 3,763 eligible women from Yiyuan County in Yimeng mountainous areas of rural Shandong, China, were enrolled and underwent Pap smear, HR-HPV DNA testing by Hybrid Capture 2 (HC2), and VIA /VILI tests. Women positive in any test were referred to colposcopy and biopsy as indicated. RESULTS The prevalence of HR-HPV infection among all enrolled women was 11.1% and that in healthy women was 9.9%. In total 33 cases of CIN1, 16 cases of CIN2, 6 cases of CIN3 but none of cervical cancer were detected and the crude prevalence of CIN2+ was 0.58%. For detecting CIN2+, the sensitivity of HR-HPV DNA testing, VIA/VILI, Pap smear was 90.9%, 77.3%, 81.8%, respectively. Pap smear had the best specificity of 98.2%, followed by HR-HPV DNA testing with specificity of 89.4%, VIA/VILI had the lowest specificity of 81.2%. Colposcopy referral rate of HR-HPV DNA testing, VIA/VILI, Pap smear was 11.1%, 18.5%, 2.3%, respectively. CONCLUSIONS Our results suggest that HR-HPV DNA testing alone might be appropriate for primary cervical cancer screening in rural low-resource areas of Shandong Province, China.
