Abstract
OBJECTIVE To investigate the prevalence of high-risk (HR) human papillomavirus (HPV) detection and HPV vaccination among women undergoing cervical cancer screening during the HPV vaccination era at Siriraj Hospital - Thailand's largest national tertiary referral center. METHODS This prospective cross-sectional study was conducted at our center's outpatient gynecology clinic during September-December 2021. Women aged ≥18 years with no previous hysterectomy, no history of preinvasive or invasive cervical cancer, and no current pregnancy who visited for cervical cancer screening were eligible for enrollment. Women with abnormal vaginal discharge/bleeding, and specimens with inadequate cellularity were excluded. We collected sociodemographic data, history of HPV vaccination, cervical cytology results, and high-risk HPV testing results. Reverse transcription polymerase chain reaction was used to determine HPV genotype. RESULTS A total of 216 women (mean age: 41.7 years (range: 25-65), 75.9% premenopausal) were enrolled. Twenty of 216 (9.3%) women tested positive for HR-HPV, and 15 of 216 (6.9%) women had been previously vaccinated for HPV. The most common HPV genotypes detected were Group B infection (HPV 35/39/51/56/59/66/68) (38.9%), followed by HPV16 (27.78%), Group A infection (HPV 31/33/52/58) (27.8%), and HPV18 (5.56%). No HPV45 infection was detected. The detection rate of cytologic abnormalities was 4.16%. Three-quarters (77.8%) of patients with cytologic abnormalities were HR-HPV positive. CONCLUSION Among the 216 women who underwent cervical cancer screening in this study, there was a 9.3% prevalence of HR-HPV infection, and a 6.9% prevalence of HPV vaccination. Among the 15 vaccinated women, 2 tested positive for HPV16 (1 normal cytology, 1 abnormal cytology).

Abstract
OBJECTIVES The addition of p16/Ki-67 dual immunostaining to human papilloma virus (HPV) screening tests has been shown to increase the detection rate of high-grade cervical intraepithelial neoplasia. Thus, the aim of this study was to evaluate the accuracy of p16/Ki67 dual staining in the detection of cervical intraepithelial neoplasia 2 (CIN2+) in women with high-risk HPV infection. MATERIALS AND METHODS A cross-sectional study was conducted between August 2017 and August 2019 at the Chulabhorn Hospital in Bangkok, Thailand. Women aged 20-70 years who underwent co-testing and tested positive for high-risk (HR) HPV (N = 215) were invited to participate in the study. P16/Ki67 testing was performed on residual cytological materials. Colposcopic biopsies were performed on all patients, and the results were correlated with positive or negative p16/Ki-67 test results. RESULTS The sensitivity and specificity of p16/Ki-67 dual staining in the detection of CIN2+ in the women with HR HPV infection were 74.4 % and 63.4 %, respectively. Compared with liquid-based cytology (LBC), p16/Ki67 cytology had similar sensitivity (p = 1.000) and specificity (p = 0.561) to LBC for detecting CIN2+. CONCLUSION In this study, p16/Ki67 dual staining in HPV triage demonstrated a test performance similar to that of LBC.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of high-risk (HR) and vaccine-type human papillomavirus (HPV) infection among Thai schoolgirls who were not included in the national HPV immunization program. METHODS Cross-sectional surveys were conducted among grade 10 (15-16 years old) and grade 12 (17-18 years old) schoolgirls in two provinces of Thailand. Urine samples were collected using the Colli-PeeⓇ device from November 2018 to February 2019. The samples were initially tested using CobasⓇ 4800. Subsequently, all Cobas-positive samples and 1:1 matched Cobas-negative samples were tested by AnyplexⓇ assay. Prevalences of any HPV, any HR HPV, vaccine-type HPV, and individual HR HPV types were estimated by school grade. RESULTS Prevalences of any HPV and any HR HPV were 11.6% and 8.6% for grade 10, and 18.5% and 12.4% for grade 12 schoolgirls, respectively. Prevalences of bivalent vaccine-type HPV infection in grades 10 and 12 were 3.4% and 4.5%, respectively. Prevalences of quadrivalent and nonavalent vaccine-type HPV infections were 4.0%/6.6% and 6.4%/10.4% in grades 10 and 12, respectively. HPV16 was the most common type detected, followed by HPV58, 51, and 52. Circulating HR HPV types were similar between the school grades. CONCLUSION A substantial burden of HR HPV infections was found among unvaccinated high school girls in Thailand.

[PMID: 36308365 PMCID: PMC9924320 DOI: 10.31557/apjcp.2022.23.10.3405] [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: 05/10/2022] [Indexed: 11/06/2022] Open
Abstract
OBJECTIVE Cervical cancer screening can effectively reduce new cervical cancer cases, including in Thailand. The abnormal results are subsequently referred for colposcopy. To avoid unnecessary colposcopy, an efficient triage is still needed for validation. This study aimed to investigate the overall positivity of cytology-based screening, HPV detection, and p16/Ki-67 dual staining and evaluate different triage strategies for predictive diagnosis of abnormal cervical lesions in northeastern Thailand. METHODS Cervical cells were collected from 191 women who came for cervical screening in the gynecological outpatient department during March 2019-February 2020. Pap smear samples were classified into 6 groups including 17 atypical glandular cells (AGC), 21 atypical squamous cells of undetermined significance (ASC-US), 7 atypical squamous cells - cannot exclude HSIL (ASC-H), 26 low-grade squamous intraepithelial lesions (LSILs), 19 high-grade SILs (HSILs) and 101 no squamous intraepithelial lesion (noSIL). Polymerase chain reaction (PCR) was performed for HPV DNA detection. HPV genotyping was determined by reverse line blot hybridization. P16/Ki-67 dual staining was performed by using CINtec PLUS Cytology kit. Biopsies from abnormal screening were collected for surgical pathology classification. RESULTS High-risk HPV (HR-HPV) infection was 2.97%, 29.41%, 38.10%, 57.14%, 46.15% and 84.21% in noSIL, AGC, ASC-US, ASC-H, LSIL and HSIL cytology respectively. P16/ Ki-67 in noSIL, AGC, ASC-US, ASC-H, LSIL and HSIL was 0.99%, 5.88%, 9.52%, 42.86%, 26.92% and 63.16%, respectively (P-value < 0.001). Among p16/Ki-67 positive cases, 96.15% (25/26) were infected with HPV and 84.62% (22/26) were HR-HPV. The overall positivity of each and co-testing between cytology or HPV DNA testing or p16/Ki-67 dual staining was evaluated. In each cervical lesion, primary HPV DNA testing showed the highest sensitivity, but low specificity. The combined all HPV/HR-HPV with p16/Ki-67 detection increased the specificity of abnormal cervical lesions. CONCLUSION P16/Ki-67 dual stain cytology in HPV-positive women performs well for diagnosis of abnormal cervical lesions and should be considered for management of HPV-positive women to avoid unnecessary colposcopy referrals.

Abstract
Background Virtually all invasive cervical cancers are caused by persistent genital human papillomavirus (HPV) infection. Therefore, HPV-based screening becomes an essential tool as one of the cervical prevention strategies to reduce the disease burden. Population-specific epidemiologic information on HPV infection among women with cytological abnormalities is essential to inform the strategy of HPV-based screening programme. The study also explored the presence of cutaneous HPV types (Beta-β and Gamma-γ) in cervical infections. Methods A cross-sectional study on Chinese women aged ≥25 years who were referred to public specialist out-patient clinics for colposcopy or further management of cervical cytological abnormalities were recruited between 2015 and 2016 in Hong Kong. HPV was detected and typified by the novel PCR-based Next-Generation Sequencing (NGS) strategies. Results The overall HPV infection rate was 74% and detected in 222 of the 300 respondents, with the prevalence of cutaneous HPV infection being 2.3%. The overall prevalence of HPV infection among women with current cytological abnormalities was 79.1% (197/249). The age-specific prevalence of HPV (any-type HPV infection) among women with cytological abnormalities reached the first peak with 87.9% in the age group of 35–39 years and gradually declined to 56.0% at 55–59 years. While a second peak occurred at 65 years or above (92.9%). HPV58 (13.7%), HPV52 (11.7%), HPV53 (11.2%), HPV16 (10.0%), HPV18 (5.2%), and HPV51 (5.2%) were the top five high-risk HPV genotypes among women with cytological abnormalities. Any-HPV type infection was significantly associated with an abnormal cervical smear (OR = 3.7; 95% CI 2.0–7.1), and high-risk HPV infection was also significantly associated with an abnormal cervical smear (OR = 6.3; 95% CI 3.0–13.5). Conclusion New evidence on the second peak of HPV infection at ≥65 years old suggests the necessity to review the current guideline for the cervical screening program extending to age 65 and above. Moreover, the high prevalence of two HPV genotypes—high-risk HPV51 and potential high-risk HPV53, among women with cytological abnormalities—suggests further research work is needed to confirm the contributory role of HPV51 and HPV53 in cervical cancer and the need for inclusion in the next generation of the HPV vaccine.

Abstract
Background Human papillomavirus (HPV) infection is the main cause of cervical cancer. Characteristics of HPV infections, including the HPV genotype and duration of infection, determine a patient’s risk of high-grade lesions. Risk quantification of cervical lesions caused by different HPV genotypes is an important component of evaluation of cervical lesion. Data and evidence are necessary to gain a deeper understanding of the pathogenicity of different HPV genotypes. The present study investigated the clinical characteristics of patients infected with single human papillomavirus (HPV) 53. Methods This retrospective study analyzed the clinical data of patients who underwent cervical colposcopy guided biopsy between October 2015 and January 2021. The clinical outcomes and the follow-up results of the patients with single HPV53 infection were described. Results 82.3% of the initial histological results of all 419 patients with single HPV53 infection showed negative (Neg). The number of patients with cervical intraepithelial neoplasia (CIN)1, CIN2, CIN3, vaginal intraepithelial neoplasia (VaIN)1, CIN1 + VaIN1, CIN1 + VaIN2, and CIN2 + VaIN2 was 45, 10, 2, 9, 6, 1, and 1, respectively. Cancer was not detected in any patient. When the cytology was negative for intraepithelial lesion or malignancy (NILM), atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesion (LSIL), we observed a significant difference in the distribution of histological results (P < 0.05). 95 patients underwent follow-up with cytology according to the exclusion criteria. No progression of high-grade lesions was observed during the follow-up period of 3–34 months. Conclusions The lesion caused by HPV53 infection progressed slowly. The pathogenicity of a single HPV53 infection was low.

Abstract
Objective Human papillomavirus (HPV) infection is the risk factor for cervical cancer. Consequently, HPV DNA testing is an essential method for cervical cancer screening. Yet, data on the prevalence and genotype distribution of HPV and cervical cytological among women in northern Jiangsu Province of China are very limited. Materials and Methods A total of 36,500 women were enrolled at the Department of Pathology of Jinhu County People’s Hospital between January 1, 2016 and December 31, 2019. HPV genotypes was performed using YanengBio® Human Papillomavirus Genotyping Kit. Thin liquid cytology tests (TCT) were conducted, based on cytology conditions set by Bethesda in 2001. Results The overall prevalence of HPV infection was 28.95%; it was age-dependent; the number of infections was highest in the 40–49 age group. Six thousand three hundred eighty-two women (16.87%) were found to have a pure high-risk HPV infection, while 918 women (2.43%) were found to have a pure low-risk HPV infection. The 6 most predominant genotypes were HPV 52, 58, 16, 53, 56, and 33. Moreover, 8923 women (45.09%) were affected by ASCUS, 4531 (22.90%) by LSIL, 3726 (18.83%) by ASC-H, and 2610 (13.19%) by HSIL. Conclusion This study revealed a high burden of HPV infection among women in northern Jiangsu Province of China and identified the distribution of the prevalent top 6 HPV genotypes in this area, which can be used as a useful reference for future work.

Abstract
Even when receiving combination antiretroviral therapy, women living with HIV are at high risk of human papillomavirus (HPV) infection and/or cervical lesions, including cancer. Using data from the PapilloV prospective cohort, we evaluated the prevalence of high-risk HPV (HR-HPV) infections after cervical lesion treatment and investigated factors associated with their carriage. Women were followed up for three years with annual Pap smear and HPV genotyping. We offered treatment to women presenting either a Pap smear with high-grade squamous intraepithelial lesion or higher, and/or a biopsy showing cervical intraepithelial neoplasia II or III. We compared the prevalence of HR-HPV infection at the time of first treatment indication and at the end of follow-up among women who received treatment and those who did not. Overall, 46 women had treatment indication. HR-HPV prevalence significantly decreased from 67% to 27% (p value = 0.001) in the 30 women who received treatment, while it did not significantly decrease (from 56% to 38%) in the 16 women who did not (p value = 0.257). Due to lack of statistical power, the 40% relative difference in HR-HPV carriage between treated and untreated women was not significant. In women living with HIV, the treatment of a cervical lesion may be beneficial for clearing HR-HPV infections.

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.

Abstract
Due to the invasive procedure associated with Pap smears for diagnosing cervical cancer and the conservative culture of developing countries, identifying less invasive biomarkers is of great interest. Quantitative label-free mass spectrometry was performed to identify potential biomarkers in the urine samples of patients with cervical cancer. This technique was used to study the differential expression of urinary proteomes between normal individuals and cancer patients. The alterations in the levels of urinary proteomes in normal and cancer patients were analyzed by Progenesis label-free software and the results revealed that 60 proteins were upregulated while 73 proteins were downregulated in patients with cervical cancer. This method could enrich high molecular weight proteins from 100 kDa. The protein-protein interactions were obtained by Search Tool for the Retrieval of Interacting Genes/Proteins analysis and predicted the biological pathways involving various functions including cell-cell adhesion, blood coagulation, metabolic processes, stress response and the regulation of morphogenesis. Two notable upregulated urinary proteins were leucine-rich α-2-glycoprotein (LRG1) and isoform-1 of multimerin-1 (MMRN1), while the 3 notable downregulated proteins were S100 calcium-binding protein A8 (S100A8), serpin B3 (SERPINB3) and cluster of differentiation-44 antigen (CD44). The validation of these 5 proteins was performed by western blot analysis and the biomarker sensitivity of these proteins was analyzed individually and in combination with receiver operator characteristic curve (ROC) analysis. Quantitative mass spectrometry analysis may allow for the identification of urinary proteins of high molecular weight. The proteins MMRN1 and LRG1 were presented, for the first time, to be highly expressed urinary proteins in cervical cancer. ROC analysis revealed that LRG1 and SERPINB3 could be individually used, and these 5 proteins could also be combined, to detect the occurrence of cervical cancer.

Hum Vaccin Immunother 2019; 15:1889-1896. [PMID: 30735478 PMCID: PMC6746534 DOI: 10.1080/21645515.2019.1578598] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/11/2019] [Accepted: 01/26/2019] [Indexed: 01/07/2023] Open
Abstract
Background: Genotype distribution and prevalence of human papillomavirus (HPV) among women vary from different regions and crowds, prophylactic HPV vaccin could prevent some diseases related to HPV, which include cervical precancerous lesions and cancer. Baseline surveys prior to mass HPV vaccination are critical to determine vaccine efficacy and detect changes in HPV type after vaccination. Objective: The aim of this study is to study the HPV type-specific prevalence in 698 women with cytological abnormalities, aging from 18 to 77 years old. Additionally, the association between HPV infection and cervical disease was investigated as well. Methods: A total of 698 cervical specimens of cytological abnormalities were collected from the First Affiliated Hospital of Xinjiang Medical University. The Thinprep liquid-based cytologic test (TCT) was performed and the cytological status was classified according to Bethesda 2001. The samples were tested HPV genotype by the PCR-based hybridization gene chip assay. Results: Overall, the HPV prevalence was 54.87%, and it was shown to be age dependent, and with the decreasing and zigzag prevalence until the age of 55 years. 204 patients (53.26%) were infected with pure high-risk HPV, 139 (36.30%) with pure low-risk HPV, and 40 (10.44%) with mixed HPV types. HPV16 was the most common type (35.36%), followed by HPV58 (13.62%) and HPV52 (9.15%). In this study, 386 (55.30%) were affected by ASCUS, 11 (1.58%) by ASC-H, 137 (19.63%) by L-SIL and 151 (21.63%) by H-SIL. Women with a cytology result of ASCUS, ASC-H, L-SIL and H-SIL had the infection of HPV 39.12%, 54.17%, 70.80% and 80.79% respectively. Conclusions: In conclusion, this study presents the first investigation about the prevalence of HPV infection and HPV genotype distribution in Xinjiang women who have abnormal cytological tests. Prior to HPV immunization in Xinjiang's population, our results could be baseline data and validation set, which provide robust available estimates of the prevalence of type-specific HPV.

Prevalence of oncogenic Human papillomavirus and genetic diversity in the L1 gene of HPV16 HPV 18 HPV31 and HPV33 found in women from Vojvodina Province Serbia. Biologicals 2019; 58:57-63. [PMID: 30795963 DOI: 10.1016/j.biologicals.2019.02.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Revised: 02/09/2019] [Accepted: 02/11/2019] [Indexed: 01/27/2023] Open
Abstract
The main purpose of this paper is to estimate the pre-vaccination prevalence of 12 hrHPV types among 564 women from Vojvodina province (Serbia). The corrected contingency coefficient (Ccorr) was used to estimate the importance of association of examined HPV types and cytological diagnosis. The highest association with the abnormal cytology was observed for HPV 16 (Ccorr = 0.493) in all age groups of participants. The effect of HPV 16 was especially clear within the group of women older than 35 years (Ccorr = 0.691), compared with women younger than 35 (Ccorr = 0.333). The molecular characterization at the level of L1 gene of HPV 16, 18, 31 and 33 variants was for the first time assessed in our region. Nearly all HPV 16 isolates cluster with variant lineage A (96.4%) the remaining isolates clustering with variant lineage D. All of HPV 18 and HPV 33 isolates are clustering within the lineage A while isolates of HPV 31 group with lineages A and C. This contributes to understanding of intrinsic geographical and biological differences of examined HPV types and could be useful for development of cervical cancer screening strategies in Vojvodina (Serbia) and diagnosis of HPV related cervical cancer in general.

SAGE Open Med 2018; 6:2050312118765604. [PMID: 29623202 PMCID: PMC5881963 DOI: 10.1177/2050312118765604] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Accepted: 02/26/2018] [Indexed: 12/19/2022] Open
Abstract
Background: Among developing countries, Thailand shows no increase in the incidence of human papillomavirus–driven oropharyngeal cancer. The causal role of human papillomavirus infection in this pathology has not been researched thoroughly. Methods: A hospital-based, case–control study was performed which included 104 patients with newly diagnosed oral and oropharyngeal squamous cell carcinomas and 104 individuals without cancer. The Cervista high-risk human papillomavirus and 16/18 assays were used to detect human papillomavirus. Odds ratios were used to assess the association between high-risk genotypes of human papillomavirus and the cancers. Results: High-risk human papillomavirus was detected in 4 of 52 (7.7%) oral cancer cases, 6 of 52 (11.5%) oropharyngeal cancer cases, and 1 of 104 (0.96%) control subjects. Of 104 cancer patients in the study, 83 were smokers. High-risk human papillomavirus was significantly associated with oropharyngeal cancer (odds ratio = 13.44, 95% confidence interval = 1.6–114.8) but was nonsignificantly associated with oral cancer (odds ratio = 8.58, 95% confidence interval = 0.9–78.9). However, after adjustment for smoking, high-risk human papillomavirus was determined to be nonsignificantly associated with oropharyngeal cancer (adjusted odds ratio = 5.83, 95% confidence interval = 0.8–43.5). Conclusion: Although low human papillomavirus prevalence was observed, the rate of high-risk human papillomavirus infection in the cancer group was still higher than that in the control group. Smoking may have an influence on the etiology of human papillomavirus–related cancers. However, the study is underpowered to clarify the role of human papillomavirus as the independent risk factor for oral and oropharyngeal cancers in the Thai population.

Abstract
Background Cervical cancer is the most common cancer in women living in Vientiane, Lao People’s Democratic Republic (PDR). This study examines cervical cytology using a liquid-based cytology (LBC) method and reports the presence of high-risk (HR) human papillomavirus (HPV). Methods We collected cervical samples from 1475 asymptomatic and healthy volunteers from six hospitals in Lao PDR. A total of 1422 volunteers (mean age 39.1 ± 6.4 years, range 30-54 years) were included in the final analysis. We performed HPV typing using the polymerase chain reaction technique to detect HR-HPV samples with abnormal cytology. Results The overall rates of abnormal cytology and HR-HPV–positive in the samples were 9.3% (132/1422) and 47.7% (63/132), respectively. The samples with abnormal cytology included 13 high-grade squamous intraepithelial lesions and one squamous cell carcinoma case. The results showed that the most common type of HPV was HPV16 (20.5%) followed by HPV58 (9.1%). Conclusions Healthy women in Vientiane, the capital of Lao PDR, have high rates of abnormal cervical cytology and are likely to be HR-HPV-positive. A system for detection and prevention of cervical cancer in these women should be developed in the near future.

Abstract
ObjectivesCervical cancer is a largely preventable disease, and the strategic implementation of a cervical cancer prevention programme is partly dependent on the impact of human papillomavirus (HPV) infection interpreted within the context of the country’s sociodemographic attributes. The objective of this study is to determine the prevalence of cervicovaginal HPV infection among a healthy, community-based, multiethnic Malaysian population. The HPV prevalence was subsequently correlated to the individual’s sociodemographics and sexual/reproductive history. Of significance, the observed prevalence captured was in a birth cohort not included in the national school-based HPV vaccination programme.MethodsThis was a cross-sectional study where 1293 healthy women aged between 18 and 60 years were recruited via convenience sampling from five community-based clinics in Selangor, Malaysia. Cervicovaginal self-samples were obtained and DNA was extracted for HPV detection and genotyping. A comprehensive questionnaire was administered to determine the sociodemographics and behavioural patterns of participants.ResultsThe median age at enrolment was 37 years old (IQR: 30–47). In total, 86/1190 (7.2%) of the samples collected were positive for HPV infection, with the highest HPV prevalence (11.9%) detected in the subgroup of 18–24 years old. The top three most prevalent HPV genotypes were HPV 16, 52 and 58. The independent risk factors associated with higher rates of HPV infection included Indian ethnicity, widowed status and women with partners who are away from home for long periods and/or has another sexual partner.ConclusionsThe overall prevalence of HPV infection in this Malaysian multiethnic population was 7.2%, with 6.5% being high-risk genotypes. The top three most common high-risk HPV types were HPV 16, 52 and 58. This information is important for the planning of primary (HPV vaccination) and secondary (screening) cervical cancer prevention programmes in Malaysia.

Abstract
BACKGROUND Following the well-established relationship between human papillomavirus (HPV) and cervical carcinoma, the carcinogenicity of this virus has also been confirmed in subsets of head and neck carcinoma (HNCA), but mainly in the oropharynx. Other subsites of HNCA with less known association to HPV have never been studied in Thailand. Accordingly, the aim of this study was to investigate the prevalence of HPV DNA in hypopharyngeal and laryngeal squamous cell carcinoma in Thai population. METHODS This cross-sectional study included hypopharyngeal and laryngeal squamous cell carcinoma patients diagnosed and treated at the Department of Otorhinolaryngology, Siriraj Hospital during the September 2011-December 2013 study period. Presence of HPV genome was confirmed by polymerase chain reaction from pathologically-confirmed fresh specimens. Demographic data and risk factors of HPV infection were evaluated. RESULTS Eighty patients were included, and 95% of those were male. Only one patient was noted with positive HPV-62 serotype. Most patients consumed tobacco and/or alcohol. Five patients had no risk factors for cancer development. Risk of HPV infection was evaluated by self-reporting questionnaire. The mean age of sexual debut was 20.17 years. Forty-eight patients had multiple sexual partners. Sixteen and seven patients had history of sexually transmitted disease infection and habitual oral sex contact, respectively. CONCLUSION There was no oncogenic HPV DNA detected within pathologic specimens of laryngeal and hypopharyngeal cancers in this study. Compared to rates reported from developed countries, the prevalence of HPV-related HNCA in Thailand is very low.

Abstract
Human papillomavirus (HPV) is the leading cause of cervical cancer. Urine-based HPV testing offers a simple and non-invasive method because of its increasing acceptance. A total of 164 pairs of cervical swab and urine samples from Thai women who underwent cervical cancer screening were used for HPV testing with HPV GenoArray Diagnostic Kits. The overall concordance percentage for HPV detection in the cervical swab and urine samples was 65.2%. The HPV genotypes most commonly detected were HPV16 and HPV18. An analysis of the urine samples and a second analysis of the cervical swab samples showed that the differences in the overall HPV detection rate between women with normal and abnormal cytology were not significant (p > 0.05). Urine samples processed with the GenoArray assay is an alternative for women who decline to undergo Pap smear even though it is not ideal as the first-line screening option.

Abstract
Objective: To study the performance of visual inspection with acetic acid plus 4-quadrant cervical biopsy (V4B) by general practitioners in detecting high grade cervical lesion, compared to highest histopathologic grade from the American Society for Colposcopy and Cervical Pathology American Society for Colposcopy and Cervical Pathology (ASCCP) 2013 work up guidelines. Materials and methods: Patients with abnormal cervical cytologic screening results suggesting low grade lesions underwent V4B by general practitioners followed by colposcopy on the same day bases on ASCCP 2013 guidelines. Those with Pap smears indicative of high grade lesions or cervical cancer were sent to V4B before confirmed diagnosis and and therapeutic excisional procedures. Predictive performance of V4B was evaluated against the reference diagnosis. Results: Compared with the reference diagnosis in 100 of patients, V4B by general practitioners had sensitivity, specificity, PPV, and NPV of 67.9%, 100%, 100%, and 88.9%, respectively. There were 11.1% false negatives with no false positives. No complications were observed following this technique. Conclusion: Overall, V4B by general practitioners demonstrates moderate accuracy when compared with definite diagnosis by colposcopy and/or LEEP. This novel strategy performed better in those with low grade lesions on cervical cytological screening.

Abstract
We evaluate the potential for using high-risk human papillomavirus (hr-HPV) testing-based screening for cervical intraepithelial neoplasia (CIN) in routine health services in Thailand; its accuracy in comparison to that of conventional cytology (CC); and the utility of HPV16/18 positive results and liquid-based cytology (LBC) triage for HPV-positive women in the detection of high-grade CIN. Women aged 30-60 years in Ubon Ratchathani province, Thailand were screened with CC and hr-HPV testing and those abnormal on either tests were referred for colposcopy and/or directed biopsies. The final diagnosis using COBAS was based on histology or colposcopy when histology was not available. Estimation of test accuracy parameters was done using latent class analysis using Bayesian models. Of the 5004 women were enrolled, 20 (0.4%) had abnormal CC and 174 (3.5%) women were HPV-positive. Among 185 women abnormal on CC or HPV-positive, 176 (95.1%) underwent colposcopy, of whom 101 (57.4%) had abnormal colposcopy findings. Ninety-seven women with abnormal and 69 with normal colposcopy had biopsies performed. All 21 women with histological CIN2 or worse had hr-HPV and none were abnormal on CC. The estimated sensitivity, specificity and positive predictive value were respectively 71.8%, 97.0% and 13.0% of HPV testing; 53%, 98.7% and 20.3% for triage of HPV-positive women with LBC; and 70.4%, 98.2% and 16.9% when test positivity was taken as HPV16/18 irrespective of LBC result or positive for hr-HPV non 16/18 types and LBC triage. Our study findings indicate poor performance of cytology screening and demonstrate the potential and utility of using HPV testing in public health services in Thailand as well as the utility of primary HPV testing and LBC triage in screening for cervical neoplasia.

Abstract
Objective: The aim of this study was to compare the efficacy of HPV 16/18 genotyping test, high risk HPV DNA testing, alone and in conjunction with the liquid-based cytology method in screening for cervical cancer precursors. Methods: A Markov model was used to describe the course of the cases of CIN2+ that had been detected over a 35 year period. Screening programs started at age 30 and were performed at an interval of once every five years. The model compared three strategies of HPV 16/18 genotyping with reflex cytology triage, high-risk HPV testing alone with referral to colposcopy and cytology-based screening with referral to colposcopy. We assumed the rate of patients lost to follow-up for those referred to colposcopy would be 0%. The clinical parameters were estimated using the data from a study conducted by the Thailand National Cancer Institute. Result: Of the three screening strategies evaluated, the high risk HPV DNA testing alone was the most effective for detecting CIN2+ over the 35 year study period. It detected 143 and 510 cases per 100,000 women more than the HPV 16/18 genotyping test and cytology-based strategy, respectively. The HPV genotyping test detected 368 cases per 100,000 women more than the cytology-based approach. In addition, when viewed with five year intervals, there were missed cases totaling approximately half of the detected cases screened by the cytology strategy and 10% of cases detected with screening by the HPV genotyping test. Conclusion: This study strongly indicates that HPV/DNA testing is preferable to cytology-based screening for cervical cancer precursors. However, the balance between the benefits, burdens and cost of each screening program should be considered.

Genetic variability in E6, E7 and L1 genes of Human Papillomavirus 62 and its prevalence in Mexico. Infect Agent Cancer 2017; 12:15. [PMID: 28270859 PMCID: PMC5336664 DOI: 10.1186/s13027-017-0125-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2016] [Accepted: 02/20/2017] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is the main etiological agent of cervical cancer, the third most common cancer among women globally and the second most frequent in Mexico. Persistent infection with high-risk HPV genotypes is associated with premalignant lesions and cervical cancer development. HPVs considered as low risk or not yet classified, are often found in coinfection with different HPV genotypes. Indeed, HPV62 is one of the most prevalent HPV detected in some countries, but there is limited information about its prevalence in other regions and there are no HPV62 variants currently described. The aim of this study was to determine the prevalence of HPV62 in cervical samples from Mexican women and to identify mutations in the L1, E6 and E7 genes, which have never been reported in our population. METHODS HPV screening was performed by Cobas HPV Test in women who attended prevention health programs and dysplasia clinics. All HPV positive samples (n = 491) and 87 additional cervical cancer samples were then genotyped with Linear Array HPV Genotyping test. Some samples were selected to corroborate genotyping by Next-Generation sequencing. On the other hand, nucleotide changes in L1, E6 and E7 genes were determined using PCR, Sanger sequencing and analysis with the CLC-MainWorkbench 7.6.1 software. L1 protein structure was predicted with the I-TASSER server. RESULTS Using Linear Array, HPV62 prevalence was 7.6% in general population, 8% in Cervical Intraepithelial Neoplasia grade 1 (CIN1) samples and 4.6% in cervical samples. The presence of HPV62 was confirmed with Next-Generation sequencing. Regarding L1 gene, novel sequence variations were detected, but they did not alter the tertiary structure of the protein. Moreover, several nucleotide substitutions were found in E6 and E7 genes compared to reference HPV62 genomic sequence. Specifically, three non-synonymous sequence variations were detected, two in E6 and one in E7. CONCLUSIONS HPV62 is a frequent HPV genotype found mainly in general population and in women with CIN1, and in 90.5% of the cases it was found in coinfection with other HPVs. Novel nucleotide changes in its L1, E6 and E7 genes were detected, some of them lead to changes in the protein sequence.

Abstract
Introduction: Cervical cancer probably represents the best-studied human cancer caused by a viral infection and the causal association of this preventable cancer with human papilloma virus (HPV) is well established. Worldwide there is a scarcity of data regarding HPV prevalence with vast differences existing among populations. Objective: The aim of this meta-analysis was to determine the community-based HPV prevalence estimates among asymptomatic women from urban and rural set ups and in participants of cancer screening clinics. Study design: Systematic review and meta-analysis. Methods: PubMed-Medline, CINAHL, Scopus, and Google scholar were systematically searched for studies providing prevalence data for HPV infection among asymptomatic women between 1986 and 2016. Results: The final analysis included 32 studies comprising a population of 224,320 asymptomatic women. The overall pooled HPV prevalence was 11% (95% confidence interval (CI), 9%-12%). The pooled HPV prevalence of 11% (95% CI, 9%-11%) was observed among women attending cervical cancer screening clinics. The pooled HPV prevalences were 10% (95% CI 8%-12%) and 11% (95% CI 4%-18%) from urban and rural areas respectively, indicating higher infection rates among the rural women with the least access to cancer screening and cancer care. Conclusion: The prevalence rates in this systematic quantitative review provide a reliable estimate of the burden of HPV infection among asymptomatic women from developed as well as developing nations. Rural women and women attending cervical cancer screening programmes feature higher genital HPV prevalences compared to their urban counterparts.

Abstract
INTRODUCTION In this study we aimed to determine the overall and type-specific prevalence of cervical human papillomavirus (HPV) infection and risk factors for such infection among women in rural Nepal, and to investigate the distribution of HPV infection by cervical cytology. MATERIAL AND METHODS The study was conducted among women aged ≥15 years in five rural villages within Kavre District in Nepal. Sociodemographic data and information on risk factors for cervical cancer were obtained through an interview, and a cervical specimen was collected for HPV DNA detection and typing using the Anyplex™ ll HPV28 Detection system, and for Papanicolaou test. RESULTS Among the 1289 women in whom a valid HPV result was obtained the median age was 40 years (range 17-86 years). Overall, the HPV prevalence was 14.4%, 7.9% for high-risk and 6.5% for low-risk HPV types, and was similar between age groups. The five most common HR types were HPV-18 (2.3%), HPV-51 (1.2%), HPV-59 (1.1%), HPV-31 (0.9%), and HPV-16 (0.8%). The prevalence of high-risk types in women with and without abnormal cytology was 8.3 and 7.7%, respectively. HPV infection was associated with current smoking, formal education, and being married to a husband with at least one previous marriage. CONCLUSIONS This is the first population-based study to report the prevalence of a broad range of HPV types among women from rural Nepal. These data are crucial for development of preventive strategies to reduce cervical cancer burden in the country.

Abstract
Between the years of 2010-2012, it was estimated there were a total of 112,392 new cases of cancers in Thailand, thus, the total age-standardized rate (ASR) per 100,000 is 137.6. In regards to the most prevalent types of cancer in female, breast cancer has the highest ASR, followed by cervical cancer (ASR=14.4); liver and bile duct cancer; colon and rectum cancer; trachea, bronchus and lung cancer; ovarian cancer (ASR=6.0); thyroid cancer; non-Hodgkin lymphoma and uterine cancer (ASR=4.3). The trend of cervical cancer in Thailand is decreasing, one key factor in making this possible was the employment of dual tract strategy (Pap smear and visual inspection with acetic acid [VIA]) by the government in 2005. In the future, the government is also considering integrating human papillomavirus (HPV) vaccination into the national immunization program, which may assist in the prevention of cervical cancer. By studying the statistical data of gynecologic cancer, it will be possible to formulate measures for the prevention, control and treatment of gynecologic cancer. Eventually, it will potentially improve the quality of life (QoL) of patients as well as decrease the mortality rate caused by gynecologic cancer.

Abstract
Background Testing for high-risk human papillomavirus DNA (HPV test) has gained increasing acceptance as an alternative method to cytology in cervical cancer screening. Compared to cytology, HPV test has a higher sensitivity for the detection of histologic high-grade squamous intraepithelial lesion or worse (HSIL+), but this could lead to a large colposcopy burden. Genotyping for HPV16/18 has been recommended in triaging HPV-positive women. This study was aimed to evaluate the screening performance of HPV testing and the role of genotyping triage in Northern Thailand. Methods A population-based cervical screening program was performed in Chiang Mai (Northern Thailand) using cytology (conventional Pap test) and HPV test (Hybrid Capture 2). Women who had abnormal cytology or were HPV-positive were referred for colposcopy. Cervical samples from these women were genotyped using the Linear Array assay. Results Of 5,456 women, 2.0% had abnormal Pap test results and 6.5% tested positive with Hybrid Capture 2. Of 5,433 women eligible for analysis, 355 with any positive test had histologic confirmation and 57 of these had histologic HSIL+. The sensitivity for histologic HSIL+ detection was 64.9% for Pap test and 100% for Hybrid Capture 2, but the ratio of colposcopy per detection of each HSIL+ was more than two-fold higher with Hybrid Capture 2 than Pap test (5.9 versus 2.8). Genotyping results were available in 316 samples. HPV52, HPV16, and HPV58 were the three most common genotypes among women with histologic HSIL+. Performance of genotyping triage using HPV16/18/52/58 was superior to that of HPV16/18, with a higher sensitivity (85.7% versus 28.6%) and negative predictive value (94.2% versus 83.9%). Conclusions In Northern Thailand, HPV testing with genotyping triage shows better screening performance than cervical cytology alone. In this region, the addition of genotyping for HPV52/58 to HPV16/18 is deemed necessary in triaging women with positive HPV test.

Abstract
Data of HPV genotype including 16 high-risk HPV (HR-HPV) and 4 low-risk HPV from 38,397 women with normal cytology, 1341 women with cervical cytology abnormalities, and 223 women with ISCC were retrospectively evaluated by a hospital-based study. The prevalence of high-risk HPV (HR-HPV) was 6.51%, 41.83%, and 96.86% in women with normal cytology, cervical cytology abnormalities, and ISCC, respectively. The three most common HPV types were HPV-52 (1.76%), HPV-16 (1.28%), and HPV-58 (0.97%) in women with normal cytology, whereas the most prevalent HPV type was HPV-16 (16.85%), followed by HPV-52 (9.55%) and HPV-58 (7.83%) in women with cervical cytology abnormalities. Specifically, HPV-16 had the highest frequency in ASC-H (24.16%, 36/149) and HSIL (35.71%, 110/308), while HPV-52 was the most common type in ASC-US (8.28%, 53/640) and LSIL (16.80%, 41/244). HPV-16 (75.78%), HPV18 (10.31%), and HPV58 (9.87%) were the most common types in women with ISCC. These data might contribute to increasing the knowledge of HPV epidemiology and providing the guide for vaccine selection for women in Shantou.

Abstract
BACKGROUND Women infected with human immunodeficiency virus (HIV) have higher rates of persistent infection with high-risk human papillomavirus (hr-HPV) and cervical and anal dysplasia. We describe the epidemiology of hr-HPV, and cervical and anal intra-epithelial abnormalities in HIV-infected women in Thailand. METHODS HIV-infected women aged 18-49 years, either HAART-naïve or -experienced, were enrolled in Bangkok, Thailand. A demographic and sexual-risk behaviour questionnaire was administered and a pelvic examination with colposcopy was performed on every woman. Cervical and anal samples were tested for cytology and HPV genotyping. RESULTS A total of 256 women were enrolled with a median [interquartile range (IQR)] age of 35 (32-40) years. Ninety (35.2%) had detectable cervical hr-HPV. Being post-menopausal was associated with increased risk for cervical hr-HPV, while years since HIV diagnosis and plasma HIV RNA <40 copies/mL were significantly associated with decreased risk in multivariable regression analyses. Abnormal cervical cytology was detected in 6.3%. Cervical biopsies that were taken from 99 women (39.3%) owing to abnormalities seen during colposcopy showed cervical intra-epithelial neoplasia (CIN) in 22.6%. The sensitivity of cervical cytology to detect CIN2+ was 10.0%. Among 102 women enrolled in the anal substudy, 18.8% had anal HPV infection and 11.1% had anal hr-HPV. Two women had abnormal anal cytology. CONCLUSION We found cervical and anal hr-HPV in 35.2% and 11.1% of Thai HIV-infected women, respectively. Moreover, the observed poor agreement between cervical cytology and histology results could indicate current cervical cancer screening programs for HIV-infected women might not be optimal for the detection of pre-neoplastic lesions.
