Real-world effectiveness of cytology and HPV-based screening strategy in cervical cancer screening: A cross-sectional population-based study in Chengdu, China. PLoS One 2024; 19:e0299651. [PMID: 38422039 PMCID: PMC10903839 DOI: 10.1371/journal.pone.0299651] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 02/12/2024] [Indexed: 03/02/2024] Open
Abstract
Cervical cancer poses a significant health challenge in developing countries, emphasizing the need for appropriate screening strategies to accelerate the elimination of this disease. This study summarized the results of a large-scale community-based cervical cancer screening program conducted in Chengdu, China, to understand the prevalence of HPV infection and cervical lesions in the population, and to compare the real-world effectiveness of two different screening methods implemented in the program. From January 2021 to December 2022, a total of 363,376 women aged 35-64 years in Chengdu received free screenings. Among these participants, 70.1% received cytology screening and 29.9% received HPV testing combined with 16/18 genotyping and cytology triage. Ultimately, 824 cases of high-grade lesions and cervical cancer were detected, with a total detection rate of cervical cancer and precancerous lesions of 226.8 per 100,000. The follow-up rate of patients with high-grade lesions and above was 98.9%, and the treatment rate was 86.6%. The overall high-risk HPV infection rate was 11.7%, with the HPV 16/18 infection rate of 1.4%. The rate of abnormal cytology results was 2.8%. The attendance rates for colposcopy and histopathology were 71.6% and 86.1%, respectively. By calculating the age-standardized rates to eliminate the different age composition between the two group, the HPV-based screening strategy had a higher rate of primary screening abnormalities (3.4% vs. 2.8%, P<0.001), higher attendance rates of colposcopy (76.5% vs. 68.9%, P<0.001) and histopathological diagnosis (94.1% vs. 78.0%, P<0.001), higher percentage of abnormal colposcopy results (76.0% vs. 44.0%, P<0.001), and higher detection rate of cervical precancerous lesions and cancer (393.1 per 100,000 vs. 156.4 per 100,000, P<0.001) compared to cytology screening. Our study indicates that the combination of HPV testing with 16/18 genotyping and cytology triage has demonstrated superior performance in cervical cancer screening compared to cytology alone in large-scale population.

Malignancy Associated with Low-Risk HPV6 and HPV11: A Systematic Review and Implications for Cancer Prevention. Cancers (Basel) 2023; 15:4068. [PMID: 37627099 PMCID: PMC10452364 DOI: 10.3390/cancers15164068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/28/2023] [Accepted: 08/08/2023] [Indexed: 08/27/2023] Open
Abstract
High-risk human papillomavirus (HPV) is etiologically related to cervical cancer, other anogenital cancers and oropharyngeal carcinomas. Low-risk HPV, especially HPV6 and HPV11, cause genital warts and laryngeal papillomas. However, the accumulating data suggests that HPV6 and HPV11 may cause malignant lesions at non-cervical anatomic sites. This review aims to estimate the proportions of single and dual HPV6/11 infections in multiple cancers reported in the last 10 years in the Cochrane, Embasa and PubMed databases. Secondly, the genomes of HPV6/11 were compared with the most common high-risk genotype, HPV16, to determine the similarities and differences. A total of 11 articles were selected, including between one and 334 HPV+ cancer patients. The frequencies of single or dual HPV6/11 infections ranged between 0-5.5% for penile and 0-87.5% for laryngeal cancers and were null for vulvar, vaginal and oral cancers. The genomic similarities between HPV6/11 and HPV16 mainly involved the E7 gene, indicating a limited ability to block cell differentiation. The presence of single or dual HPV6/11 infections in variable proportions of penile and laryngeal cancers support the vaccination strategies that cover these genotypes, not only for preventing genital warts but also for cancer prevention. Other risk factors and co-carcinogens are likely to participate in epithelial carcinogenesis associated with low-risk HPV.

Abstract
ObjectivesWe investigated HPV genotypes in a large cohort of patients with definitive cervical histologic diagnosis.MethodsHPV testing was performed by real-time PCR assay, including 18 high-risk HPV (hrHPV) and 3 low-risk HPV (lrHPV). Totally 61,422 patients with documented HPV genotyping results within 6 months before cervical histologic diagnoses were included.ResultsHrHPV positive rate was 55.1% among all tested cases with the highest in adenosquamous carcinoma (94.1%), followed by squamous cell carcinoma (SCC) (93.7%), cervical intraepithelial neoplasia 2/3 (CIN2/3) (92.8%). HrHPV positive rates were significantly higher in high-grade squamous lesions than in those in glandular lesions. HPV16 was the most common genotype followed by HPV52 and HPV58 in CIN2/3. The most frequent hrHPV genotype in adenocarcinoma in situ (AIS) was HPV18, followed by HPV16, HPV45 and HPV52. In SCC cases, HPV16 was the most common type followed by HPV58, HPV52, HPV18 and HPV33. However, HPV18 showed significantly higher prevalence in adenocarcinoma and adenosquamous carcinoma than in that in SCC. Theoretically, the protective rates of 2/4-valent and 9-valent vaccine were 69.1% and 85.8% for cervical cancers.ConclusionsThe prevalence of HPV genotypes in Chinese population was different from that in Western population. Some hrHPV types were identified in cervical precancerous lesions and cancers, which are not included in current HPV vaccines. These data provide baseline knowledge for future HPV vaccine development.

Prevalence and Genotype Distribution of Human Papillomavirus Among Attendees at a Sexually Transmitted Diseases Clinic in Urban Tianjin, China. Int J Gen Med 2021; 14:1983-1990. [PMID: 34045890 PMCID: PMC8144902 DOI: 10.2147/ijgm.s308215] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 04/21/2021] [Indexed: 01/02/2023] Open
Abstract
Background Human papillomavirus (HPV) is linked to various cancers in males and females. The prevalence and genotype distribution of HPV vary depending on geographical region and the immunity provided by vaccines. Investigation of HPV epidemiology is of great meaning for the development of prevention programs. Methods From January 2017 to September 2019, using PCR-reverse dot blot hybridisation, we determined the HPV subtypes in 2801 patients 17-89 years old at the sexually transmitted diseases (STD) clinic of Tianjin Medical University General Hospital. Results The HPV infection rate was 50.79% in males and 50.64% in females. The most common HPV genotype in males and females was HPV6 (30.15% and 30.43%), followed by HPV16 (18.76% and 20.65%) and HPV11 (14.61% and 15.67%). Infection with a single HPV subtype predominated in both males and females, and the rate in males was higher than in females. By contrast, the rate of high-risk HPV (hrHPV) and low-risk HPV (lrHPV) mixed infection in females was higher than in males. Most HPV-positive patients were 20-39 years of age. The prevalence of infection with only hrHPV differed among the age groups; the peak age was 50 to 59 years. Conclusion The HPV prevalence was higher among the STD clinic outpatients than the general population. Therefore, a large-scale survey of high-risk populations is needed. It is anticipated that HPV vaccines, regular education and physical examinations may have a significant impact on the prevention of HPV-related diseases in high-risk groups.

Abstract
Background HPV persistent infection is a strong carcinogenic factor that can induce cervical cancer. Investigation of HPV epidemiology and genotype distribution is of great meaning for the development of cervical cancer prevention and control strategies. Methods By using PCR-based hybridization gene chip assay, HPV genotype was detected from 14,185 women that came from HEC (Health Examination Center) or OGOC (Obstetrics and Gynecology Outpatient Clinics) between 2015 and 2017 in Sichuan area. The epidemiology and genotype distribution as well as the relationship between HPV infection and histology/cytology abnormalities were analyzed. Results The positivity rate of HPV was 23.84%. The HPV-positive rate of OGOC group (37.62%) was significantly higher than that of HEC group (15.29%), p < 0.05. The prevalence of HPV reached peak at age 41–50 (5.86%) in HEC group, but at age 21–30 (14.74%) in OGOC group. Of all the HPV positive women, single genotype infection was the most common form in both HEC and OGOC group (62.06% in total screening population, 74.36% in HEC group and 54.01% in OGOC group). Three most prevalent HPV types were HPV-52 (5.02%), 58 (3.61%), and 16 (3.24%) in total screening population. Of all the HPV positive women, the top three types were HPV-52 (20.93%), CP8304 (15.32%), and 58 (14.42%) in HEC group, while were HPV-52 (21.14%), 16 (16.34%), and 58 (15.61%) in OGOC group. HPV 52/16/58 accounted for 41.84% of cytology and 56.52% of histological abnormalities. Conclusions Women in Sichuan area were facing the great threat of HPV infection, especially the women aged between 21 ~ 30 or 41–50 years old. The priority HPV types were HPV 52, 58, and 16 in OGOC group, while were HPV 52, CP8304, and 58 in HEC group. HPV 52/16/58 accounted for the majority of cytology and histological abnormalities. Our analysis was found to be valuable for providing a scientific basis for the prevention and control strategies of cervical cancer in Sichuan area.

Influencing Factors of High-Risk Human Papillomavirus Infection and DNA Load According to the Severity of Cervical Lesions in Female Coal Mine Workers of China. J Cancer 2019; 10:5764-5769. [PMID: 31737113 PMCID: PMC6843890 DOI: 10.7150/jca.29034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Accepted: 07/27/2019] [Indexed: 12/24/2022] Open
Abstract
High-risk human papillomavirus (HR-HPV) plays an aetiological role in the progression of cervical cancer and precancerous lesions. Determining the risk factors of HR-HPV infection is useful for HR-HPV infection surveillance and control. We aimed to explore the influencing factors of HR-HPV infection in female coal mine workers, and to evaluate the associations between HR-HPV DNA load and cytological and histological changes of cervix. In total 6,325 participants completed standard questionnaire on potential influencing factors of HR-HPV infection and underwent gynecological examinations, HPV test as well as Thinprep cytology test (TCT). 1,512 women with positive results of HPV and/or TCT were referred to colposcopy with biopsy and histological examination. HR-HPV DNA load was evaluated by Digene second generation hybrid capture (HC2) assay. Multiple unconditional logistic regression analysis was used to determine the influencing factors for HR-HPV infection. Of 6,325 study participants, 1,405 (22.2%) were HR-HPV positive. HR-HPV infection rate was higher in women aged 30-50 years, with lower education level, working inside the mines and engaging in shift work. Risk factors for HR-HPV infection in female coal mine workers included contraception (OR=1.395, 95%CI=1.102-1.458), previous artificial abortion (OR=1.603, 95%CI=1.202-1.856), working inside the mines (OR=1.230, 95%CI=1.056-1.528) and history of gynecological diseases (OR=1.198, 95%CI=1.001-1.462), while menopause was a protective factor (OR=0.402, 95%CI=0.306-0.507). The HR-HPV DNA load significantly increased with the severity of cervical cytological (χ 2 trend=177.372, p<0.001) and histological (χ 2 trend=194.501, p<0.001) changes. The results indicated that HR-HPV infection is highly prevalent in female coal mine workers in China. Contraception, artificial abortion, working inside the mines and gynecological diseases could increase the risk of HR-HPV infection in these women. HR-HPV DNA load might predict risks of cervical precancerous lesions and cancer. Our findings could provide scientific basis for reducing the risk of HR-HPV infection and cervical cancer in this vulnerable population.

[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.

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

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

Abstract
Human papillomavirus (HPV) are well known to be associated with the development of cervical cancer. HPV16 and HPV 18 are known as high-risk types and reported to be predominantly associated with cervical cancer. The prevalence and genetic diversity of HPV have been well documented globally but, in the Kingdom of Saudi Arabia, data on HPV genetic diversity are lacking. In this study, we have analyzed the genetic diversity of both HPV16 and HPV18 based on their L1 gene sequence because L1 gene is a major capsid protein gene and has been utilized to develop a prophylactic vaccine. In January 2011-2012, a total of forty samples from cervical specimens of women in Saudi Arabia were collected. The association of HPV16, HPV18 was detected by polymerase chain reaction, sequenced and submitted to GenBank. The sequences identity matrix and the phylogenetic relationship were analyzed with selected HPVs. The highest sequence identity (99.5%) for HPV16 and (99.3%) for HPV was observed with selected HPVs. The phylogenetic analysis results showed that HPVs from Saudi Arabia formed a closed cluster with African, Asian, East Asian as well as American HPVs distributed into multiple linages from various geographical locations. The results provided the valuable information about genetic diversity, but there is an urgent need to generate full genome sequence information which will provide a clearer picture of the genetic diversity and evolution of HPVs in Saudi Arabia. In conclusion, the generated data will be highly beneficial for developing molecular diagnostic tools, analyzing and correlating the epidemiological data to determine the risk of cervical cancer and finally to develop a vaccine for Saudi Arabian population.
