Abstract
A next-generation sequencing (NGS)-based Ezplex HPV NGS kit (SML Genetree, Seoul, Korea) was used for human papillomavirus (HPV) screening. Of 885 cervical swab samples, HPV was detected in 162 samples. High-risk HPVs were detected in 82 samples, and other types of HPV were detected in 13 samples (HPV86, 71, 102, 91, and 114). At the read depth ≥ 500, NGS results exhibited 100 % agreement among repeated tests. HPV NGS results were compared with those of real-time PCR assays, Anyplex HPV28 (Seegene, Seoul, Korea) (n = 383) and Cobas HPV (Roche, Mannheim, Germany) (n = 64); concordances were 92.4 % and 95.0 %, respectively. Sanger sequencing of discordant results (n = 13) produced compatible results with those of HPV NGS. Pap smear abnormalities were detected in 31 patients (3.5 %), and 19 patients had high-risk HPV. Using HPV NGS for screening, rare HPV subtypes were detected, and quantitative values were obtained as read depth.

Abstract
OBJECTIVE High-risk human papillomavirus (HR-HPV) infection is a leading cause of cervical cancer, of which human papillomavirus (HPV)-16 and HPV-18 account for about 70% of cases. Since HPV infection is common, it is important to focus on the HPV genotypes that pose the highest risk for effective cervical cancer screening. In this study, we evaluated the clinical usefulness of HPV-16/HPV-18 genotyping for cervical cancer screening. METHODS A total of 86,022 women aged 25 years or older was analyzed in this study. Sensitivity, specificity, positive predictive value, and negative predictive value of HPV genotyping and cytology were analyzed. In addition, we subdivided participants into two groups according to cytology results, negative for intraepithelial lesion of malignancy (NILM) and atypical squamous cells of undetermined significance (ASC-US), and analyzed absolute risk (AR) and relative risk (RR) of cervical intraepithelial neoplasia (CIN) 3 or worse according to HPV genotype. RESULTS The AR of CIN 3 or worse was 77.0 times higher in HR-HPV-positive compared to HR-HPV-negative. Compared to 12 other HR-HPV-positive, the AR of CIN 3 or worse was 4.2 times higher in HPV-16 and/or HPV-18 positive. This finding was more evident in women with NILM than in women with ASC-US. The RR of CIN 3 or worse was 7.0 in women with NILM and 4.5 in women with ASC-US. CONCLUSION Regardless of the cytology results, the risk of CIN 3 or worse was higher in HPV-16/HPV-18 than in other HR-HPV. HPV-16/HPV-18 genotyping is recommended to screen women with a high risk of cervical cancer.

Abstract
Background Human papillomavirus (HPV) can cause various gynecological diseases, create a long-term inflammatory immune microenvironment, and induce the occurrence of cervical tumors. However, the prevalence of HPV is species-specific in different eras or in different countries and regions. This paper aimed to investigate the characteristics of HPV infection in the Xuhui District, Shanghai City, China. Methods We collected HPV data from 6,760 female testers, focusing on the younger population for data analysis. We focused more on the HPV subtypes to which young women were susceptible, performed t-Distributed Stochastic Neighbor Embedding (TSNE) analysis to screen for characteristic subtypes, and compared the prevalent subtypes lacking effective vaccine protection. Results HPV infection exhibited a trend of affecting a younger population, and eight subtypes were more likely to occur in young people. HPV43, 51, 53, and 59 showed a higher incidence and lacked vaccine protection. We performed TSNE dimensionality reduction analysis to organize the HPV data. The results indicated that HPV16, 18, and 51 are characteristic subtypes in the younger population. The Thinprep cytologic test (TCT) also revealed that the infection with HPV43, 51, 53, and 59 also triggers significant pathological phenotypes. Conclusions HPV51 is a subtype that occurs more frequently in young women, can induce a variety of significant pathological features, and lacks effective vaccine protection. This study inspires us to take measures to deal with HPV rejuvenation and conduct research on vaccines for specific HPV subtypes.

Chua B, Lim LM, Ng JSY, Ma Y, Wee HL, Caro JJ. Cost-Effectiveness Analysis of HPV Extended versus Partial Genotyping for Cervical Cancer Screening in Singapore. Cancers (Basel) 2023; 15:1812. [PMID: 36980698 PMCID: PMC10046888 DOI: 10.3390/cancers15061812] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 03/13/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023] Open
Abstract
Human papillomavirus (HPV) partial genotyping (PGT) identifies HPV16 and HPV18 individually, alongside 12 other high-risk HPV genotypes (hrHPV) collectively. HPV extended genotyping (XGT) identifies four additional hrHPV individually (HPV31, 45, 51, and 52), and reports the remaining eight in three groups (HPV33|58; 56|59|66; 35|39|68). Quality-adjusted life years (QALY), health care resource use, and costs of XGT were compared to PGT for cervical cancer screening in Singapore using DICE simulation. Women with one of the three hrHPV identified by XGT (HPV35|39|68; 56|59|66; 51), and atypical squamous cells of undetermined significance (ASCUS) on cytology, are recalled for a repeat screening in one year, instead of undergoing an immediate colposcopy with PGT. At the repeat screening, the colposcopy is performed only for persistent same-genotype infections in XGT, while with PGT, all the women with persistent HPV have a colposcopy. Screening 500,122 women, aged 30-69, with XGT, provided an incremental cost-effectiveness ratio (ICER) versus PGT of SGD 16,370/QALY, with 7130 (19.4%) fewer colposcopies, 6027 (7.0%) fewer cytology tests, 9787 (1.6%) fewer clinic consultations, yet 2446 (0.5%) more HPV tests. The XGT ICER remains well below SGD 100,000 in sensitivity analyses, (-SGD 17,736/QALY to SGD 50,474/QALY). XGT is cost-effective compared to PGT, utilizes fewer resources, and provides a risk-based approach as the primary cervical cancer screening method.

Cervical intraepithelial neoplasia in non-16/18 high-risk human papilloma virus positive/cytology negative women: An alternative approach in poor resource areas. Taiwan J Obstet Gynecol 2023; 62:299-303. [PMID: 36965899 DOI: 10.1016/j.tjog.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/14/2022] [Indexed: 03/27/2023] Open
Abstract
OBJECTIVE Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative cases and assessing the distribution of non-16/18 hr-HPV subtypes. MATERIALS AND METHODS This cross-sectional study was conducted on 138 non-16/18 hr-HPV positive/cytology negative women, who were referred to the gynecologic oncology clinic of Yas hospital, affiliated with Tehran University of Medical Sciences, January 2021 to 2022. RESULTS Among the detected types, HPV 31 was the most frequent type. 63 cases underwent biopsy as indicated based on colposcopic examination with acetic acid 3% application among which 34 had normal results. In the remaining 29 cases, 25 had insignificant findings. CIN2 was reported in 2 cases, one with HPV 31, 45, 58, and the other with HPV 58. CIN3 was also detected in 2 cases, one with HPV 31 and the other with HPV 35, 45. The overall incidence of high-grade CIN was 2.8%. A statistically significant (P-value = 0.046) difference was detected between patients with high-grade CIN compared with the others regarding the Hookah usage. CONCLUSION The risk of CIN among non-16/18 hr-HPV positive/cytology negative cases is noticeably low. Based on ASCCP guidelines return testing at 1 year without immediate colposcopy seems sufficient; however, because of many reasons doing immediate colposcopy rather than 1-year follow-up may be a more accessible approach in resource poor, low-income countries such as ours.

[PMID: 36687652 PMCID: PMC9845708 DOI: 10.3389/fmicb.2022.1094560] [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: 11/10/2022] [Accepted: 12/08/2022] [Indexed: 01/06/2023] Open
Abstract
Background Human papillomavirus (HPV) infection is closely correlated with cervical lesions. However, the HPV prevalence varies among different districts. This retrospective study investigated the HPV genotype distribution and its relationship with cervical lesions in southern Hunan Province. Methods The database at our Pathology Department was searched for HPV and morphological results during 2018-2020 were reviewed. A total of 49,955 gynaecological inpatients and outpatients, each of whom underwent HPV testing based on the amplification of L1 sequence and reverse dot blot hybridization, were included in this study. Available cytology and relevant histological examination results were reviewed. Enrolled cases were categorized into seven groups based on their age. Household registry and educational level were evaluated. Results Seven thousand two hundred eighty-six females were positive for HPV and the overall HPV positivity rate was 14.59%. The top five most prevalent HPV genotypes were HPV52, 16, 58, 53 and 51 (22.98%, 17.54%, 14.29%, 7.47%, and 5.70%, respectively). The HPV prevalence curve specific to the seven age groups showed a bimodal distribution. High school education or blow and rural residence served as risk factors for HPV infection. Single infection was the main type of HPV infection, and multiple infections occurred in 21.92% of the infected women. Of 3,148 cases had cytological results, 1,149 (36.50%) had abnormal cytological abnormalities. Among 2,833 participants with histological examination, 2000 (70.60%) had cervical abnormalities. Cytological and pathological abnormalities were mainly associated with infection with HPV16, 52 and 58. Further analysis found that HPV16, 58, 52 and 33 were the main genotypes associated with high-grade squamous lesions (HSIL) and that HPV16, 31, 33 and 58 were independent risk factors for HSIL (odd ratio [OR] = 1.70, 1.99, 2.59, 2.29; 95% CI = 1.41-2.03, 1.17-3.41, 1.88-3.59, 1.85-2.82; all p < 0.05). HPV16, 58, 52, 18 and 33 were the most frequent genotypes detected in squamous cell carcinoma (SCC) patients, and HPV16 and 18 were independent risk factors for cervical carcinomas (OR = 6.72;95% CI = 5.48-8.25; p < 0.001; OR = 1.67, 95% CI = 1.22-2.30; p = 0.001). Conclusion This retrospective study demonstrated the prevalence and the distribution characteristics of HPV infection and its correlation with cervical lesions in southern Hunan Province. The comprehensive results of this survey can guide HPV vaccine research to protect against some common genotypes in China.

Absolute Risk and Attributable Fraction of Type-Specific Human Papillomavirus in Cervical Cancer and Precancerous Lesions-A Population-Based Study of 6286 Women in Rural Areas of China. J Clin Med 2022; 11:jcm11216483. [PMID: 36362711 PMCID: PMC9655002 DOI: 10.3390/jcm11216483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/24/2022] [Accepted: 10/26/2022] [Indexed: 11/06/2022] Open
Abstract
Background: To investigate the human papillomavirus (HPV) genotype distribution among the general population and assess the attribution of HPV genotypes targeted by vaccines to protect against cervical lesions theoretically. Methods: Cervical samples were collected from women aged 21 to 64 years old from Inner Mongolia and Shanxi Province in China who had not been vaccinated against HPV. HPV type-specific absolute risk (AR) to classified cervical lesions was calculated and then the attributable fraction (AF) was estimated, together with the combined contributions of the HPV types, targeted by four available HPV vaccines and five HPV vaccines in clinical trials in China to protect against cervical lesions. Results: A total of 6286 women with an average age of 44.1 years ± 8.41 (range: 21−64) participated in the study. The age distribution of 14 HR-HPV and HPV16/18 all showed a ‘U’ shape, which peaked in the ≤25 year-group and >55 year-group. The five most common genotypes were HPV16 (4.3%), HPV52 (4.1%), HPV58 (2.1%), HPV51 (2.1%), and HPV66 (1.7%). The prevalence of HPV types 6 and 11 infections was 1.1% and observed with n significant differences across age stratifications in China. AF to CIN2+ was predominated by HPV 16 with 56.2%, followed by HPV58 (12.0%), HPV52 (8.5%), HPV18 (4.3%), and HPV51 (2.9%). HPV52 and 58 in the prophylactic HPV vaccine would enhance the protection against CIN2+ by approximately 20%. Conclusions: Regarding multi-valent HPV vaccine development in China, the HPV types 16, 52, 58, and 18 should be given priority for their high prevalence at the population level, high AR, notable AF, and high relative risk to high-grade cervical lesions.

Abstract
Presently, human papillomavirus (HPV)-based cervical cancer screening is commonly used and is replacing conventional cytology screening tests. The HPV genotyping assay is useful for triage in cervical cancer screening and the evaluation of HPV vaccination effects. In this study, we evaluated the clinical performance of two HPV genotyping assays, BD Onclarity HPV (Onclarity) and Seegene Anyplex II HPV28 (Anyplex) in the detection of relevant cervical lesions and for HPV genotyping concordance. Anyplex and Onclarity assays were performed on 920 consecutive liquid-based specimens. Anyplex, sensitivity, specificity, and genotyping concordance with Onclarity were optimal when restricted to ≥2+ (medium) viral loads. HPV genotyping agreement between the two assays ranged between 0.75 and 0.9 (excellent), except for HPV 33/58, which was 0.73 (good). With Onclarity as a reference, the relative sensitivity of Anyplex for the detection of ≥CIN 2 was 1.05 (95% CI: 0.99–1.1) and the relative specificity for detection of negative for intraepithelial lesion and malignancy (NILM) was 0.89 (95% CI: 0.85–0.93). For most ≥CIN 2 lesions, high-risk HPV was detected by Onclarity (66/72) and Anyplex (69/72) assays. For high-risk HPV negative ≥CIN 2 lesions, possible high-risk HPV genotypes were detected by Anyplex. In conclusion, the genotyping agreement between the tests was good to excellent. Full genotyping with Anyplex might confer additional benefits to patients with ≥CIN 2, although the difference is small. We also suggest an optimal cutoff value when reporting HPV infections using the Anyplex assay (≥2+; medium viral loads).

Abstract
BACKGROUND Persistent human papillomavirus (HPV) infection is a key factor for the development and progression of cervical cancer. We sought to identify the type-specific HPV prevalence by cervical cytology and assess disease progression risk based on high-risk persistent HPV infection in South Korea. METHODS To investigate the HPV prevalence by Pap results, we searched seven literature databases without any language or date restrictions until July 17, 2019. To estimate the risk of disease progression by HPV type, we used the Korea HPV Cohort study data. The search included the terms "HPV" and "Genotype" and "Korea." Studies on Korean women, type-specific HPV distribution by cytological findings, and detailed methodological description of the detection assay were included. We assessed the risk of disease progression according to the high-risk HPV type related to the nonavalent vaccine and associated persistent infections in 686 HPV-positive women with atypical squamous cells of uncertain significance or low-grade squamous intraepithelial lesions from the Korea HPV Cohort Study. Type-specific HPV prevalence was the proportion of women positive for a specific HPV genotype among all HPV-positive women tested for that genotype in the systematic review. RESULTS We included 23 studies in our review. HPV-16 was the most prevalent, followed by HPV-58, -53, -70, -18, and -68. In women with high-grade squamous intraepithelial lesions, including cancer, HPV-16, -18, and -58 were the most prevalent. In the longitudinal cohort study, the adjusted hazard ratio of disease progression from atypical squamous cells of uncertain significance to high-grade squamous intraepithelial lesions was significantly higher among those with persistent HPV-58 (increase in risk: 3.54-5.84) and HPV-16 (2.64-5.04) infections. CONCLUSIONS While HPV-16 was the most prevalent, persistent infections of HPV-16/58 increased the risk of disease progression to high-grade squamous intraepithelial lesions. Therefore, persistent infections of HPV-16 and -58 are critical risk factors for cervical disease progression in Korea. Our results suggest that equal attention should be paid to HPV-58 and -16 infections and provide important evidence to assist in planning the National Immunization Program in Korea.

Current Updates on Cancer-Causing Types of Human Papillomaviruses (HPVs) in East, Southeast, and South Asia. Cancers (Basel) 2021; 13:cancers13112691. [PMID: 34070706 PMCID: PMC8198295 DOI: 10.3390/cancers13112691] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/23/2021] [Accepted: 05/25/2021] [Indexed: 12/13/2022] Open
Abstract
Simple Summary Among the over 200 human papillomavirus (HPV) genotypes identified, approximately 15 of them can cause human cancers. In this review, we provided an updated overview of the distribution of cancer-causing HPV genotypes by countries in East, Southeast and South Asia. Besides the standard screening and treatment methods employed in these regions, we unravel HPV detection methods and therapeutics utilised in certain countries that differ from other part of the world. The discrepancies may be partly due to health infrastructure, socio-economy and cultural diversities. Additionally, we highlighted the area lack of study, particularly on the oncogenicity of HPV genotype variants of high prevalence in these regions. Abstract Human papillomavirus (HPV) infection remains one of the most prominent cancer-causing DNA viruses, contributing to approximately 5% of human cancers. While association between HPV and cervical cancers has been well-established, evidence on the attribution of head and neck cancers (HNC) to HPV have been increasing in recent years. Among the cancer-causing HPV genotypes, HPV16 and 18 remain the major contributors to cancers across the globe. Nonetheless, the distribution of HPV genotypes in ethnically, geographically, and socio-economically diverse East, Southeast, and South Asia may differ from other parts of the world. In this review, we garner and provide updated insight into various aspects of HPV reported in recent years (2015–2021) in these regions. We included: (i) the HPV genotypes detected in normal cancers of the uterine cervix and head and neck, as well as the distribution of the HPV genotypes by geography and age groups; (ii) the laboratory diagnostic methods and treatment regimens used within these regions; and (iii) the oncogenic properties of HPV prototypes and their variants contributing to carcinogenesis. More importantly, we also unveil the similarities and discrepancies between these aspects, the areas lacking study, and the challenges faced in HPV studies.

[PMID: 33847377 DOI: 10.1002/jmv.27012] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 02/08/2021] [Accepted: 04/11/2021] [Indexed: 12/16/2022]
Abstract
We aimed to study the infection status and distribution of human papillomavirus (HPV) in Yangzhou City to provide precise guidance for the prevention and treatment of cervical cancer in this area. Reproductive tract secretions were collected from patients admitted at Subei People's Hospital over the past 3 years. Fifteen high-risk HPV (HR-HPV) genotypes were analyzed by fluorescent polymerase chain reaction. The positive rate of HR-HPV in 34 420 subjects was 23.56%. There was no significant difference in the rate of overall infection between males and females (χ 2 = 0.04; p = 0.952 > 0.05). The five genotypes with high infection rates in the population were HPV52, HPV58, HPV16, HPV51, and HPV39. Single infection was found to be dominant, primarily with the HPV52 genotype. The infection rate was higher in patients less than 20 years old and more than 60 years old. Most patients with cervical intraepithelial neoplasms 2/3 and cervical cancer were infected by HPV16, followed by those infected by HPV52 and HPV58. There was a significant difference in the infection rate of HPV16 among patients with different cervical lesions (χ 2 = 31.660; p < 0.01), and the infection rate of HPV16 was higher in patients with cervical cancer than in healthy individuals. Single infection was dominant among the study patients with HPV infection in Yangzhou city. There was no significant difference in infection rate and genotype distribution between males and females. The infection rate in young and old women was higher, and the rate increased with age (>20 years).

Abstract
Objectives: Human papillomavirus (HPV) is a major cause of cervical cancer in women. The characteristics of HPV infection vary; therefore, it is necessary to identify the most common HPV genotypes among a group of subjects when introducing a vaccine program. Currently, in the Yanbian Autonomous Region, no HPV vaccinations are not provided, and no data has been reported regarding HPV rates or genotype prevalence. We aimed to find the most suitable HPV vaccine for this region and reasons why no vaccine has been introduced. Methods: HPV genotyping of 200 Korean-Chinese women living in the Yanbian Autonomous Region who visited the hospital for annual health examination was done. We also checked main factors necessary for HPV vaccine administrative system; (1) vaccine manufacturers in China, (2) vaccine importers, (3) vaccine suppliers, (4) applicable vaccine laws, (5) the HPV vaccine permit system in Jilin Province, and (6) vaccination hospital facilities-were assessed by direct inquiry and search. Results: The results showed that HPV genotypes 52, 58, 16, 53, and 33 were the most common among Korean-Chinese women. These results differed from those previously reported for Korean or Chinese women. All elements necessary for introduction of HPV vaccine were prepared, but there is no HPV vaccination plan based on epidemiological investigation. Conclusions: Gardasil® 9 should be the most suitable vaccine for Korean-Chinese women with HPV infection and cervical cancer in this region considering the prevalence of certain genotypes. Governments and medical institutions should take an active stance on HPV vaccination to lower the incidence of cervical cancer here. Our study may serve as an important reference for introducing a Chinese government program designed to prevent cervical cancer.

Fifteen new nucleotide substitutions in variants of human papillomavirus 18 in Korea : Korean HPV18 variants and clinical manifestation. Virol J 2020; 17:70. [PMID: 32448303 PMCID: PMC7245819 DOI: 10.1186/s12985-020-01337-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 05/07/2020] [Indexed: 12/04/2022] Open
Abstract
High-risk human papillomavirus (HPV) infection is an essential factor for the development of cervical cancer. HPV18 is the second most common carcinogenic HPV type following HPV16, but the lineages of HPV18 have been less well studied than those of HPV 16. The purpose of this study was to analyze the nucleotide variants in the E6, E7, and L1 genes of HPV18, to assess the prevalence of HPV18 variants in Korea and to explore the relationship between HPV18 genetic variants and the risk for cervical cancer. A total of 170 DNA samples from HPV18-positive cervical specimens were collected from women admitted to a secondary referral hospital located in Seoul. Among them, the lineages of the 97 samples could be successfully determined by historical nomenclature. All the studied HPV 18 variants were lineage A. Sublineages A1 and A4 comprised 91.7% (89/97) and 1.0% (1/97), respectively. Sublineages other than A1 or A4 comprised 7.2% (7/97). We identified 15 new nucleotide substitutions among 44 nucleotide substitutions: C158T, T317G, T443G, A560G, A5467G, A5560C, A5678C, A6155G, G6462A, T6650G, G6701A, T6809C, A6823G, T6941C and T6953C. Among them, 6 substitutions at positions 317, 443, 5467, 5560, 6462, and 6823 resulted in amino acid changes (E6: F71L and N113K; L1: H13R, H44P, A345T, and N465S, respectively). The pathologic results were classified as normal in 25.8% (25/97) of the women, atypical squamous cells of undermined significance (ASCUS) in 7.2% (7/97), cervical intraepithelial neoplasia (CIN) 1 in 36.1% (35/97), CIN2/3 in 19.6% (18/97), and carcinoma in 12.4% (12/97). There was no significant association between the HPV18 sublineages and the severity of pathologic lesion or the disease progression. This study is the first to analyze the distribution of HPV18 variants in Korean and to associate the results with pathologic findings. Although the HPV18 variants had no significant effect on the degree and progression of the disease, the newly discovered nonsynonymous mutation in L1 might serve as a database to determine vaccine efficacy in Korean women.

Abstract
Background To investigate high-risk HPV (hr-HPV) genotype distributions and the association between hr-HPV infection with severity of the cervical lesions in women with normal cytology. Methods In this cross-sectional study, the result of the hr-HPV test and biopsy of colposcopy of women with normal cytology from January 2012 to January 2019 were analyzed. The detection rate of high-grade squamous intraepithelial lesion (HSIL) and cervical cancer were calculated among different hr-HPV genotypes, viral load group, and age groups. Results Five thousand eight hundred eighty women were enrolled in this study. Overall, 59.97% had normal histological results, 19.32% had HSIL, and 1.07% had cervical cancer. The detection rate of HSIL or worse (HSIL+) in women with single HPV16(34.00%), HPV31(27.50%), HPV33(25.58%), and HPV52(20.88%) infection were higher significantly than single HPV18 (15.59%) infection, respectively. The HSIL+ detection rate between HPV16 single infection and multiple infections (excluding HPV18) was no significant difference (34% vs 35.47%, P = 0.638), contrary to HPV18(12.59% vs 21.67%, P = 0.022). In women without HPV16/18 infections, HSIL+ detection rates for single, double, and triple or more hr-HPV infections were 12.28, 20.31, and 37.50%, the risk of detection of HSIL+ significantly increasing. With the hr-HPV DNA load increases, the risk of detection of HSIL+ (χ2 = 91.01, P < 0.0001) and invasive cervical cancer (χ2 = 5.757, P = 0.016) increase. In age < 30, 31–40, 41–50, 51–60, > 60 group, HSIL+ detection rate were 24.80%、22.10%、19.59%、14.29, and 12.61%, respectively. Conclusion Women who have normal cytology with HPV 16/18/31/33/52/58 infections, multiple HPV infections and high viral load, have a higher detection rate of HSIL+.

Int J Gynecol Cancer 2019; 30:35-40. [PMID: 31792083 DOI: 10.1136/ijgc-2019-000932] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 10/22/2019] [Accepted: 10/30/2019] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE Triage with HPV genotyping has some caveats and debates for HPV positive cases other than 16 and 18. The Swede score colposcopic scoring system has not previously been evaluated in this group of patients. OBJECTIVE To use the Swede score colposcopic scoring system to compare scores and final histopathological results in women who have undergone colposcopy owing to infection with high risk-HPVs other than HPV16 and 18 and to establish new cut-off values to predict pre-malignant lesions in this group of patients. METHODS This study was conducted in 613 women undergoing colposcopic evaluation because of abnormal cervical cytology together with high-risk HPV infection. All patients referred were evaluated by an expert colposcopist, given a Swede score (using the Swede score colposcopic scoring system) by using five variables (acetowhiteness, margins plus surface, vessel pattern, lesion size, and iodine staining), and had at least one biopsy procedure (either colposcopically directed or by a loop electrical excision procedure). Sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio values, and receiver operating characteristic curves for each clinico-pathological variable to detect low-grade and high-grade squamous intra-epithelial lesions, and any squamous cell abnormality (low-grade + high-grade squamous intra-epithelial lesions) were evaluated individually. RESULTS Final histopathological results of the patients were normal in 53.2% of cases, low-grade lesions in 32.5% of cases, and high-grade lesions in 14.4% of cases. Swede score was ≥8 (median 7.97) for high-grade lesions and ≥5 (median 5.06) for low-grade lesions. The area under the curve values (95% CI) of Swede scores for low-grade and high-grade squamous intra-epithelial lesions, and low-grade + high grade lesions were 0.92, 0.98, and 0.96, respectively. A Swede score cut-off value ≥6 had a sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratios of 92%, 98%, 93%, 98%, and 50 (22.6 to 110.8), respectively, for high-grade lesions at the final pathology (P<0.001). One high-risk HPV type (except 16 and 18) was no better than another for calculating the median Swede score during colposcopy (P=0.43). CONCLUSIONS The Swede score colposcopic scoring system appears to be a useful tool for evaluating atypical cervical cytology in women with high-risk HPV infection other than HPV types 16 and 18.

Burden of Human papillomavirus (HPV)-related disease and potential impact of HPV vaccines in the Republic of Korea. PAPILLOMAVIRUS RESEARCH 2018; 7:26-42. [PMID: 30599280 PMCID: PMC6329707 DOI: 10.1016/j.pvr.2018.12.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 11/08/2018] [Accepted: 12/26/2018] [Indexed: 01/14/2023]
Abstract
Background We aimed to review the burden and the potential impact of human papillomavirus (HPV) vaccines on HPV-related diseases in the Republic of Korea and to discuss cervical cancer prevention practices in this country. Methods Cancer burden statistics were retrieved from GLOBOCAN-2018 and Statistics Korea. HPV disease burden was assessed via systematic review. Vaccine types relative contribution (RC) was estimated using data from an international project using formalin-fixed paraffin-embedded specimens. Results Despite a downtrend in cervical cancer in recent years, Korean rates remain high. In contrast, oropharyngeal cancer incidence has gradually increased and other anogenital cancers remain rare. In Korea, HPV prevalence in general population is around 20%. In cervical cancer, RC of HPVs 16/18 (74.0%) increased to 92.0% when including HPVs 31/33/45/52/58. Limited information was available for other HPV-related cancer sites. Regarding prevention, since the inclusion of the HPV vaccine into the National Immunization Program, almost half (49%) of the target cohort in 2016 had received the first dose of vaccine. Further, percentage of women screened with pap has increased from 41.1%-2009 to 53.0%-2016. Conclusions HPV-related disease burden in Korea is significant. Results suggest that the combination of effective and high coverage HPV vaccination and screening programmes could substantially impact on HPV-related disease in Korea. HPV-related disease burden (cancer and genital warts) in Korea is significant. HPV16 is the most frequent genotype, causing itself more than 60% of HPV-related cancers. HPV vaccine types 16/18/31/33/45/52/58/6/11 cause 92.0% of cervical cancers. HPV vaccines could significantly impact on the HPV-related disease burden.

Abstract
Our study aimed to assess the prevalent, incident, and persistent infection, and clearance of HPV among 19 753 individual women attending the gynecological department at a major comprehensive hospital. HPV 16, 52, and 58 ranked top three types with the highest prevalence and incidence. The prevalence of high-risk (HR) HPV peaked among women aged 15 to 19 years, then sharply decreased with age, stabilized among women aged 25 to 44 years, and then surged again among women aged 45 years and older. HR HPV infection were more likely to be prevalent (15.9% vs 1.3%, P < 0.001), incident (17.3 vs 2.0 per 1000 person-months, P < 0.001), and persistent (33.0% vs 24.2%, P = 0.033), and less likely to clear (88 vs 115 per 1000 person-months, P = 0.040) compared to low-risk HPV types. The majority of women detected with HR HPV types did not retest within 12 months. Clinical guidelines on HPV DNA testing are needed and education and counseling about HPV infection and its implications for women detected with HPV at clinical settings are warranted.

HPV-16, HPV-58, and HPV-33 are the most carcinogenic HPV genotypes in Southwestern China and their viral loads are associated with severity of premalignant lesions in the cervix. Virol J 2018; 15:94. [PMID: 29801461 PMCID: PMC5970451 DOI: 10.1186/s12985-018-1003-x] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 05/15/2018] [Indexed: 12/24/2022] Open
Abstract
Background Currently, the role of human papillomavirus (HPV)-58 in southwestern China has been unexplored. Although there is some controversy, it is proposed that the viral load of HPV correlates with the severity of intraepithelial lesions. Methods We identified 7747 patients from south Sichuan and adjacent regions who were diagnosed with HPV between 2013 and 2017. The HR-HPV subtype distribution was analyzed and the patient’s viral loads were quantified using real-time RT-PCR. Results Among all 7747 patients screened for HPV genotypes, 1728 patients (22.31%) were identified as having HR-HPV subtypes. In patients without intraepithelial lesions (12.41%), HPV-52, HPV-16, and HPV-58 were the three most prevalent HR-HPV subtypes. Moreover, HPV-16, HPV-58, and HPV-33 were the most prevalent subtypes in patients with cervical intraepithelial neoplasia grade II (CINII) (42.86%) and grade III (CINIII) (59.81%), and accounted for the majority of invasive cervical cancer (ICC) (69.34%). Thus, viral loads of HPV-58, HPV-16, and HPV-33 positively correlated with the severity of cervical lesions (P < 0.001, P = 0.016, P = 0.026, respectively). Using receiver operating characteristic (ROC) curve analysis, the optimum thresholds for predicting severe intraepithelial lesions of cases (CINI, CINIII and ICC) with HPV-16, HPV-58, and HPV-33, respectively, were obtained, which were 1, 0.93, and 0.25, respectively. Conclusion In our study, we showed that HPV-16 was the most common carcinogenic HPV subtype in southwestern China followed by HPV-58 and HPV-33. Viral loads of these subtypes are associated with the severity of premalignant lesions in the cervix.

Abstract
Cancer is a major cause of morbidity and the most common cause of death in Korea. There are currently approximately 200,000 incident cancer cases and 78,000 individuals die from cancer every year. The factors directly related to cancer incidence, including aging, smoking, obesity, and Westernized dietary habits, have been increasing during the past several decades. Since 1999, trends toward increased incidence have been observed for thyroid, breast (in women), colorectal, and prostate cancer. Currently, these trends have changed direction, and the incidence of stomach and liver cancer in both sexes, and cervical cancer in women have continually declined. Although the number of cancer deaths increased by a factor of 2.7 from 1983 to 2016, the age-standardized mortality associated with cancer has been decreasing by 3% every year. The 5-year relative survival rate (RSR) has also improved over the past several decades, especially for stomach, prostate, and breast cancer, which had 5-year RSRs greater than 90% in the most recent report.

Abstract
Background In the present study we retrospectively evaluated the results of outpatients who had an HPV analysis, and present objective evidence for the administration of preventive inoculation in our area. Material/Methods We retrospectively reviewed 532 outpatients who visited a single center between 2012 and 2016 and had an HPV infection analysis. The criteria for inclusion of patients with unhealthy cervix in the study were: erosion, chronic cervicitis, healed lacerations, hypertrophied cervix, and abnormal discharges from the cervix. Results We found that 122 out of 532 patients were infected with HPV, and the rate of multiple infections was 59.0% (72/122). HR-HPV (group 1 carcinogens HPV-16 (18.9%, 23/122), HPV-18 (13.1%, 16/122), HPV- 31 (4.9%, 6/122), HPV-33 (3.3%, 4/122), HPV-35 (7.4.9%/122), HPV-39 (5.7%, 7/122), HPV-45 (5.7%, 7/122), HPV-51 (11.5%, 15/122); Group 3 LR-HPV; HPV-6 (31.1%, 38/122), HPV-11 (26.2%, 32/122), HPV-42 (9.0%, 11/122) and HPV-43 (4.9%, 6/122). In terms of linear-by-linear association test, no significant statistical difference was identified between years. The P value for HPV infection rate on year basis was P>0.05. Conclusions In this hospital-based retrospective analysis, HPV types were found to be similar to HPV types reported in developed countries. We firmly suggest that patients should be informed about the risk of HPV infection at early ages.
