A multicentre screening cohort study in rural China. An Sist Sanit Navar 2024; 47:e1065. [PMID: 38817086 PMCID: PMC11167506 DOI: 10.23938/assn.1065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 11/11/2023] [Accepted: 12/26/2023] [Indexed: 06/01/2024]
Abstract
BACKGROUND This study aimed to assess the effectiveness of high-risk human papillomavirus (HR-HPV) primary testing for cervical cancer screening in China's rural areas. METHODS Women aged 21-64 years were recruited. Cervical cytology was diagnosed following the Bethesda 2001 classification system, HPV infection (HR-HPV, HPV-16, HPV-18, and other 12 genotypes) identified by Cobas-4800, and colposcopy and biopsy performed when required. Primary outcomes were defined as the cumulative incidence of cervical intraepithelial neoplasia grade 2/3/higher (CIN2/3+) and its relative risk at baseline and at the 36-month follow-up. RESULTS The study included 9,218 women; mean age was 45.15 years (SD: 8.74); 81% completed the follow-up. The most frequent type of cytological lesions (12.4% ) were ASCUS (8.4%) and LSIL (2.2%). HR-HPV infection (16.3%) was more prevalent in HPV-16 than in HPV-18 (3 vs 1.5%); a positive relationship with the severity of the lesions, from 29.8% in ASCUS to 89.6% in HSIL was found. At baseline, 3.5% of the patients underwent colposcopy; 20% had a positive diagnosis. At the 36-month follow-up, the cumulative incidences of CIN2+ and CIN3+ were higher in women with HR-HPV infection (16.9 vs 0.5% and 8.2 vs 0.2%). The relative risk of CIN2/3+ was lower in HR-HPV-negative women compared to those with a negative cytology at baseline (0.4; 95%CI: 0.3-0.4). CONCLUSIONS High-risk HPV-based screening may significantly reduce the risk of CIN2/3+ compared with cytology testing. This may be a new resource for public health demands in China's rural areas.

Abstract
Cervical cancer is a significant public health concern in Ethiopia. It is mainly caused by persistent infection with the human papillomaviruses. The aim of this study was to assess the relationship between carcinogenic risk of probable, possible and low risk HPV infection and those of cervical intraepithelial neoplasia (CIN) and cervical cancer. A cross sectional study nested from prospective cohort study was conducted in Bahir Dar, northwest Ethiopia. Statistical analyses were performed using SPSSversion 26.0. HPV-16 was associated with a relatively higher risk of CIN II+, (AOR = 15.42; 95% CI 6.81-34.91). In addition, HPV-52, -18, -53 and -58, were significantly associated with an increased risk of CIN II+, (AOR = 7.38 (1.73-31.54), 5.42 (1.61-18.31), 4.08 (1.53-10.87), and 3.17 (1.00-10.03)), respectively. The current study shows high rate of HPV with predominance of HPV-16, -53, -58, -18, -35, and -52. The quadrivalent and nonavalent vaccine had only covered 27.1% and 45% of the circulating HPV genotypes. Ethiopia may need to consider introduction of nonavalent vaccine into the national public health strategy. Polyvalent vaccine which includes the genotypes not covered by existing approved vaccines should be considered.

Abstract
Cervical cancer (CC) is the most prevalent gynecological malignancy and a leading cause of death among women. It is primarily caused by human papillomavirus (HPV) infection, with 99.7% of cases showing high-risk HPV genotypes. This study sheds light on HPV dynamics as well as the discrepancies of different CC screening modalities results while highlighting factors that may have contributed to such a scenario. Moreover, we underscore the importance of the non-viral etiology of CC as well. We examined the current trends of HPV infection and its effects on cervical health in women treated at a tertiary care center in Belgrade, Serbia. Patients with abnormal colposcopy findings like dysplasia and re-epithelization were more likely to test negative for HPV (p < 0.001). Interestingly, women with a positive Pap smear tested HPV negative significantly more often (p = 0.041). Finally, HPV-positive individuals were more likely to have CIN I and II histologies (p < 0.001), while CIN III occurred equally in women with and without the virus. It may be inferred that inconsistencies in detecting HPV and the presence of cervical lesions may eventually result in adjustments to screening guidelines, as is crucial to adopt a meticulous approach to promote periodical CC screening, as initial samples may test negative for HPV.

Abstract
BACKGROUND/AIM The identification of high-risk human papillomavirus (HR HPV) genotypes is important both for epidemiological purposes and because the persistence of an HPV infection with the same genotype is a necessary condition for the development of cervical cancer. The purpose of this study was to analyze the prevalence of HR HPV genotypes in women enrolled in the national program for cervical cancer screening in Lazio Region, Italy. PATIENTS AND METHODS From April to November 2022, we evaluated 30,445 samples using the Anyplex TM II HPV HR Detection test (Seegene), which identifies 14 HR HPV: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68. The data were analyzed using the SG STATS platform. RESULTS In total, 4,244 samples tested positive (13.9%); 3,290 samples (77.5%) were positive for one of the genotypes tested, and 954 (22.5%) were positive for more than one HPV genotype. The total prevalence (considering both single infection and co-infections) of the different genotypes was: HPV 16 755 cases (13.8%), HPV 31 704 (12.9%), HPV 68 580 (10.6%), HPV 66 436 (8.0%), HPV 52 413 (7.5%), HPV 58 411 (7.5%), HPV 51 400 (7.3%), HPV 56 366 (6.7%), HPV 39 293 (5.3%), HPV 59 260 (4.8%), HPV 45 231 (4.2%), HPV 33 230 (4.2%), HPV 18 222 (4.0%), HPV 35 173 (3.2%). Our results indicate that HPV 16 and 31 are the most prevalent genotypes in the Lazio region followed by HPV 68, 66, 52, 58, and 51. CONCLUSION The extended genotyping test allows a better risk stratification and the identification of multiple HPV infections.

Changes in High-Risk HPV Infection Prevalence and Associated Factors in Selected Rural Areas of China: A Multicenter Population-Based Study. Front Med (Lausanne) 2022; 9:911367. [PMID: 35903319 PMCID: PMC9319042 DOI: 10.3389/fmed.2022.911367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Accepted: 06/13/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundThe Chinese government has taken action to prevent cervical cancer by implementing the National Cervical Cancer Screening Programme in Rural Areas (NACCSPRA), which was launched in 2009. Numerous studies have demonstrated that long-term cervical cancer screening alters human papillomavirus (HPV) infection rates and cervical disease detection. Nearly 80 million women have been screened over 10 years, representing <30% of the target population; however, in some rural areas, such as Ordos City of Inner Mongolia Autonomous Region, Xiangyuan County of Shanxi Province, and Jinyun County, and Jingning County of Zhejiang Province, programs for prevention and treatment of cervical cancer have been implemented. Numerous studies have demonstrated that long-term cervical cancer screening alters rates of human papillomavirus (HPV) infection and cervical disease detection. In this study, we aimed to determine the infection rates of high-risk HPV (hrHPV) and the detection rate of cervical lesions; and changes in factors associated with cervical cancer, to provide scientific data to inform efforts to eliminate cervical cancer in rural areas.MethodsThis was a cross-sectional, population-based, and multi-center survey. Populations from three rural areas of China (Ordos City of Inner Mongolia Autonomous Region, Xiangyuan County of Shanxi Province, and Jinyun County and Jingning County of Zhejiang Province) were selected and 9,332 women aged 20–64 years old were invited to participate in cervical cancer screening by both cytology and HPV testing. The outcomes assessed were: infection rates with hrHPV, HPV16, 18, 16/18, and other 12 hrHPV types (HPV 31,33,35,39,45,51,52,56,58,59,66 and 68); detection rates of cytological and histological lesions; and factors associated with HPV infection.ResultsA total of 9,217 women aged 45.62 ± 8.02 years were included in this study. Infection rates with hrHPV, HPV 16, 18, 16/18, and other 12 hrHPV types were 16.3%, 3.0%, 1.5%, 4.3%, and 13.6%, respectively. There were significant differences among the age-specific HPV infection rates (P < 0.05). Infection rates with hrHPV, 16, 18, 16/18, and the other 12 hrHPV types showed a single peak infection mode, with a peak age of 56–65 years old. Age, marital status, number of live births, education level, reproductive disease history, and a history of alcohol consumption were risk factors for hrHPV infection. The detection rate of cytological abnormalities was 12.98% in the study and was higher in women older than 56 years old. The detection rates of cervical intraepithelial neoplasia CIN2+ and CIN3+ in the population were 1.45% and 0.77%, respectively. The highest incidence rates of CIN2+ and CIN3+ were 32.12% and 17.51%, respectively, in the 41–45 years old group.ConclusionInfection rates with hrHPV, HPV16, and cervical lesions among our screening population were lower than the mean level in rural areas of China. Infection rates with hrHPV, HPV16, 18, and 16/18 showed a single-peak infection pattern, with the peak age of infection being 56-65 years old. Risk factors for hrHPV infection were age, history of alcohol consumption, marital status, reproductive diseases, education level, and the number of live births. Based on these data, we recommend that cervical cancer screening be offered to women older than 30 years in rural areas, particularly those aged 41–45 years.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. METHODS In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. RESULTS The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p<0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16-24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p<0.05). CONCLUSIONS HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

Current Updates on Cancer-Causing Types of Human Papillomaviruses (HPVs) in East, Southeast, and South Asia. Cancers (Basel) 2021; 13:cancers13112691.

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.

J Cancer 2021; 12:4379-4388. [PMID: 34093838 PMCID: PMC8176416 DOI: 10.7150/jca.57993] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 04/27/2021] [Indexed: 12/29/2022] Open
Abstract
Objectives: Women with normal pathology screened from abnormal cervical cytology are a special population with higher progression risk than women with normal cytology. However, the associations between genotype distribution and changes of high-risk human papillomavirus (HR-HPV) infection and cervical progression risk in this special population remain unclear. Methods: A total of 1232 women with normal pathology screened from abnormal cervical cytology were enrolled into this cohort with 2-year follow-up. HPV genotyping detection was performed through flow-through hybridization. Hazard ratios (HRs) and Odds ratios (ORs) were calculated using Cox proportional hazard regression and logistic regression models, respectively. Results: Overall HR-HPV prevalence at baseline was 29.0%, with HPV16, 52, 58, 53 and 51 the top five genotypes. The 2-year persistence rate of HR-HPV infection was 31.9%. Compared with HR-HPV negative, the adjusted HRs of overall HR-HPV, HPV16, 31/33, 58, 51, and 53 infections for the progression risk of normal cervix were 5.31, 7.10, 6.95, 5.74, 5.04, and 4.88, respectively. Multiple HR-HPV infection cannot lead to an additional risk of progression relative to single HR-HPV infection. In comparison with HR-HPV persistently negative, same-type HR-HPV persistence was positively associated with progression risk of normal cervix (adjusted OR: 22.26), but different-type HR-HPV persistence was not linked to cervical progression. Conclusion: Genotypes and persistence of HR-HPV infection could stratify the cervical progression risk in women with normal cervical pathology and abnormal cytology and provide evidence for development of next generation of vaccines. HPV51 and 53 deserved attention apart from HPV16, 31, 33, and 58.
