Abstract
To assess the pattern of multiple human papillomavirus infection to predict the type replacement postvaccination. A total of 7372 women aged 18-45y from a phase III trial of an Escherichia coli-produced HPV-16/18 vaccine were analyzed at enrollment visit before vaccination. Hierarchical multilevel logistic regression was used to evaluate HPV vaccine type and nonvaccine-type interactions with age as a covariate. Binary logistic regression was construed to compare multiple infections with single infections to explore the impact of multiple-type infections on the risk of cervical disease. Multiple HPV infections were observed in 25.2% of HPV-positive women and multiple infections were higher than expected by chance. Statistically significant negative associations were observed between HPV16 and 52, HPV18 and HPV51/52/58, HPV31 and HPV39/51/52/53/54/58, HPV33 and HPV52/58, HPV58 and HPV52, HPV6 and HPV 39/51/52/53/54/56/58. Multiple HPV infections increased the risk of CIN2+ and HSIL+, with the ORs of 2.27(95%CI: 1.41, 3.64) and 2.26 (95%CI: 1.29, 3.95) for multiple oncogenic HPV infection separately. However, no significant evidence for the type-type interactions on risk of CIN2+ or HSIL+. There is possibility of type replacement between several pairs of vaccine and nonvaccine HPV type. Multiple HPV infection increased the risk of cervical disease, but coinfection HPV types seem to follow independent disease processes. Continued post-vaccination surveillance for HPV 51/52/58 types and HPV 39/51 types separately was essential after the first and second generation of HPV vaccination implementation in China.

Abstract
Females with existing high-risk HPV (HR-HPV) infections remain at risk of subsequent multiple or recurrent infections, on which benefit from HPV vaccines was under-reported. We pooled individual-level data from four large-scale, RCTs of AS04-HPV-16/18 vaccine to evaluate efficacy and immunogenicity in females DNA-positive to any HR-HPV types at first vaccination. Females receiving the AS04-HPV-16/18 vaccine in the original RCTs constituted the vaccine group in the present study, while those unvaccinated served as the control group. Vaccine efficacy (VE) against new infections and associated cervical intraepithelial neoplasia (CIN) 2+ in females DNA-negative to the considered HR-HPV type but positive to any other HR-HPV types, VE against reinfections in females DNA-positive to the considered HR-HPV type but cleared naturally during later follow-up, and levels of anti-HPV-16/18 IgG were assessed. Our final analyses included 5137 females (vaccine group = 2532, control group = 2605). The median follow-up time was 47.88 months (IQR: 45.72-50.04). For the prevention of precancerous lesions related to the non-infected HR-HPV types at baseline, VE against HPV-16/18 related CIN 2+ was 82.70% (95% CI: 63.70-93.00%). For the prevention of reinfections related to the infected HR-HPV types following natural clearance, VE against HPV-16/18 12MPI was non-significant (p > .05), albeit robust immunity persisted for at least 48 months. Females with existing HR-HPV infections at first vaccination still benefit from vaccination in preventing precancers related to the non-infected types at baseline. VE against reinfections related to the infected types following natural clearance remains to be further investigated.

Abstract
Isothermal nucleic acid amplification methods have many advantages for use at the point of care. However, there is a lack of multiplexed isothermal amplification tests to detect multiple targets in a single reaction, which would be valuable for many diseases, such as infection with high-risk human papillomavirus (hrHPV). In this study, we developed a multiplexed loop-mediated isothermal amplification (LAMP) reaction to detect the three most common hrHPV types that cause cervical cancer (HPV16, HPV18, and HPV45) and a cellular control for sample adequacy. First, we characterized the assay limit of detection (LOD) in a real-time reaction with fluorescence readout; after 30 min of amplification the LOD was 100, 10, and 10 copies/reaction of HPV16, HPV18, and HPV45, respectively, and 0.1 ng/reaction of human genomic DNA (gDNA). Next, we implemented the assay on lateral flow strips, and the LOD was maintained for HPV16 and HPV18, but increased to 100 copies/reaction for HPV45 and to 1 ng/reaction for gDNA. Lastly, we used the LAMP test to evaluate total nucleic acid extracted from 38 clinical samples; compared to qPCR, the LAMP test had 89% sensitivity and 95% specificity. When integrated with sample preparation, this multiplexed LAMP assay could be useful for point-of-care testing.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is an important factor leading to cervical cell abnormalities. 90% of cervical cancers are closely associated with persistent infection of high-risk HPV, with the highest correlation with HPV16 and 18. Currently available vaccines and antivirals have limited effectiveness and coverage. Guanylate binding protein 1 (GBP1) was induced by interferon gamma and involved in many important cellular processes such as clearance of various microbial pathogens. However, whether GBP1 can inhibit human papillomavirus infection is unclear. RESULTS In this study, we found that GBP1 can effectively degrade HPV18 E6, possibly through its GTPase activity or other pathways, and E6 protein degrades GBP1 through the ubiquitin-proteasome pathway to achieve immune escape. CONCLUSION Therefore, GBP1 is an effector of IFN-γ anti-HPV activity. Our findings provided new insights into the treatment of HPV 18 infections.

Abstract
BACKGROUND To investigate related factors for postoperative pathological upgrading of cervical biopsy to cervical cancer (CC) in patients with cervical intraepithelial neoplasia (CIN)3 after conical resection. METHODS This retrospective study collected data from patients diagnosed with CIN3 by cervical biopsies at the author's Hospital between January 2012 and December 2022. The primary outcome was the pathological results of patients after conical resection. The pathological findings were categorized into the pathological upgrading group if postoperative pathology indicated CC, while those with normal, inflammatory, or cervical precancerous lesions were classified into the pathological non-upgrading group. The factors associated with upgrading were identified using multivariable logistic regression analysis. RESULTS Among 511 patients, there were 125 patients in the pathological upgrading group (24.46%). The patients in the upgrading group were younger (47.68 ± 9.46 vs. 52.11 ± 7.02, P < 0.001), showed a lower proportion of menopausal women (38.40% vs. 53.02%, P = 0.0111), a lower proportion of HSIL (40.00% vs. 57.77%, P = 0.001), a higher rate of HPV-16/18 positive (25.60% vs. 17.36%, P = 0.011), a higher rate of contact bleeding (54.40% vs. 21.50%, P < 0.001), lower HDL levels (1.31 ± 0.29 vs. 1.37 ± 0.34 mmol/L, P = 0.002), higher neutrophil counts (median, 3.50 vs. 3.10 × 109/L, P = 0.001), higher red blood cell counts (4.01 ± 0.43 vs. 3.97 ± 0.47 × 1012/L, P = 0.002), higher platelet counts (204.84 ± 61.24 vs. 187.06 ± 73.66 × 109/L, P = 0.012), and a smaller platelet volume (median, 11.50 vs. 11.90 fL, P = 0.002).The multivariable logistic regression analysis showed that age (OR = 0.90, 95% CI: 0.86-0.94, P < 0.001), menopausal (OR = 2.68, 95% CI: 1.38-5.22, P = 0.004), contact bleeding (OR = 4.80, 95% CI: 2.91-7.91, P < 0.001), and mean platelet volume (OR = 0.83, 95% CI: 0.69-0.99, P = 0.038) were independently associated with pathological upgrading from CIN3 to CC after conical resection. CONCLUSION Age, menopausal, contact bleeding, and mean platelet volume are risk factors of pathological upgrading from CIN3 to CC after conical resection, which could help identify high risk and susceptible patients of pathological upgrading to CC.

Abstract
As human papillomavirus (HPV) immunisation and HPV-based cervical cancer (CC) screening programmes expand across sub-Saharan Africa, we investigated the potential impact of human immunodeficiency virus (HIV) status on high-risk (HR)-HPV distribution among women with CC in Côte d'Ivoire. From July 2018 to June 2020, paraffin-embedded CC specimens diagnosed in Abidjan, Côte d'Ivoire were systematically collected and tested for HR-HPV DNA. Type-specific HR-HPV prevalence was compared according to HIV status. Of the 170 CC specimens analysed (median age 52 years, interquartile range: [43.0-60.0]), 43 (25.3%) were from women living with HIV (WLHIV) with a median CD4 count of 526 [373-833] cells/mm3 and 86% were on antiretroviral therapy (ART). The overall HR-HPV prevalence was 89.4% [95% CI: 84.7-94.1]. All were single HR-HPV infections with no differences according to HIV status (P = .8). Among HR-HPV-positive CC specimens, the most prevalent HR-HPV types were HPV16 (57.2%), HPV18 (19.7%), HPV45 (8.6%) and HPV35 (4.6%), with no significant differences according to HIV status. Altogether, infection with HPV16/18 accounted for 71.1% [95% CI: 55.9-86.2] of CC cases in WLHIV vs 78.9% [95% CI: 71.3-86.5] in women without HIV (P = .3). The study confirms the major role of HPV16/18 in CC in Côte d'Ivoire and should support a regional scale-up of HPV16/18 vaccination programmes regardless of HIV status. However, vaccines targeting additional HR-HPV types, including HPV45 and HPV35, could further decrease future CC incidence in Côte d'Ivoire, both for WLHIV and women without HIV.

Abstract
Human papillomavirus (HPV) is a double-stranded DNA virus that infects cutaneous and mucosal epithelial cells. HPV replication initiates at the origin (ori), located within a noncoding region near the major early promoter. Only two viral proteins, E1 and E2, are essential for replication, with the host cell contributing other necessary factors. However, the role of host cell proteins in regulating HPV replication remains poorly understood. While several binding sites for cellular transcription factors (TFs), such as POU-HD proteins, have been mapped in the regulatory region, their functional importance is unclear. Some POU-HD TFs have been shown to influence replication in a system where E1 and E2 are provided exogenously. In this study, we investigated the impact of several POU-HD TFs on the replication of the HPV5, HPV11, and HPV18 genomes in U2OS cells and human primary keratinocytes. We demonstrated that OCT1, OCT6, BRN5A, and SKN1A are expressed in HPV host cells and that their overexpression inhibits HPV genome replication, whereas knocking down OCT1 had a positive effect. Using the replication-deficient HPV18-E1- genome, we demonstrated that OCT1-mediated inhibition of HPV replication involves modulation of HPV early promoters controlling E1 and E2 expression. Moreover, using Oct6 mutants deficient either in DNA binding or transcriptional regulation, we showed that the inhibition of HPV18 replication is solely dependent on Oct6's DNA binding activity. Our study highlights the complex regulatory roles of POU-HD factors in the HPV replication.

Abstract
BACKGROUND The first randomised controlled trial of single-dose human papillomavirus (HPV) vaccine efficacy, the Kenya single-dose HPV-vaccine efficacy (KEN SHE) trial, showed greater than 97% efficacy against persistent HPV16 and HPV18 infection at 36 months among women in Kenya. We compared antibody responses after one dose of HPV vaccine in the Dose Reduction Immunobridging and Safety Study (DoRIS), the first randomised trial of the single- dose regimen in girls aged 9-14 years, the target age range for vaccination, with those after one dose of the same vaccine in KEN SHE. METHODS In the DoRIS trial, 930 girls aged 9-14 years in Tanzania were randomly assigned to one, two, or three doses of the 2-valent vaccine (Cervarix) or the 9-valent vaccine (Gardasil-9). The proportion seroconverting and geometric mean concentrations (GMCs) at month 24 after one dose were compared with those in women aged 15-20 years who were randomly assigned to one dose of the same vaccines at the same timepoint in KEN SHE. Batched samples were tested together by virus-like particle ELISA for HPV16 and HPV18 IgG antibodies. Non-inferiority of GMC ratios (DoRIS trial:KEN SHE) was predefined as a lower bound of the 95% CI less than 0·50. FINDINGS Month 24 HPV16 and HPV18 antibody GMCs in DoRIS were similar or higher than those in KEN SHE. 2-valent GMC ratios were 0·90 (95% CI 0·72-1·14) for HPV16 and 1·02 (0·78-1·33) for HPV18. 9-valent GMC ratios were 1·44 (95% CI 1·14-1·82) and 1·47 (1·13-1·90), respectively. Non-inferiority of antibody GMCs and seropositivity was met for HPV16 and HPV18 for both vaccines. INTERPRETATION HPV16 and HPV18 immune responses in young girls 24 months after a single dose of 2-valent or 9-valent HPV vaccine were comparable to those in young women who were randomly assigned to a single dose of the same vaccines and in whom efficacy had been shown. A single dose of HPV vaccine, when given to girls in the target age range for vaccination, induces immune responses that could be effective against persistent HPV16 and HPV18 infection at least two years after vaccination.

Abstract
AIM The aim of this study was to investigate how the integration status of HPV in the vaginal epithelium affects the development of vaginal intraepithelial neoplasia (VaIN). METHODS Twenty-four vaginal tissues were collected before applying high-throughput viral integration detection (HIVID), medical records of them were documented, including age, thin-prep cytologic test (TCT) and HPV test results, colposcopic biopsy pathology, and other clinical data, such as history of total hysterectomy for cervical lesions, whether they were infected with HPV16/18 with a follow-up span of 2 years. We summarized the distribution of HPV integration on the host chromosome and HPV type, as well as the hotspot integration gene and its role in the development of VaIN. RESULTS In this study, 24 cases suffered from VaIN were involved. HPV integration was detected in 11 cases; furthermore, we discovered HPV 16 and 73, chromosome 1 and 2 possessed most HPV integration sites while EMBP1, CLO5A1, EHF, ELF5 as dominate hot spots. Taken clinical outcome into account, we found a significant difference between HPV integration occurrence and VaIN (p = 0.011). CONCLUSION (1) This study found a statistical difference between HPV integration and the occurrence of VaIN; (2) HPV integration may provide a new clinical predictor for VaIN and facilitate risk assessment and stratified management of high-risk patients.

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.

Abstract
BACKGROUND Implementation of high-risk human papillomavirus (hrHPV) screening has greatly reduced the incidence and mortality of cervical cancer. However, a triage strategy that is effective, noninvasive, and independent from the subjective interpretation of pathologists is urgently required to decrease unnecessary colposcopy referrals in hrHPV-positive women. METHODS A total of 3251 hrHPV-positive women aged 30-82 years (median = 41 years) from International Peace Maternity and Child Health Hospital were included in the training set (n = 2116) and the validation set (n = 1135) to establish Cervical cancer Methylation (CerMe) detection. The performance of CerMe as a triage for hrHPV-positive women was evaluated. RESULTS CerMe detection efficiently distinguished cervical intraepithelial neoplasia grade 2 or worse (CIN2 +) from cervical intraepithelial neoplasia grade 1 or normal (CIN1 -) women with excellent sensitivity of 82.4% (95% CI = 72.6 ~ 89.8%) and specificity of 91.1% (95% CI = 89.2 ~ 92.7%). Importantly, CerMe showed improved specificity (92.1% vs. 74.9%) in other 12 hrHPV type-positive women as well as superior sensitivity (80.8% vs. 61.5%) and specificity (88.9% vs. 75.3%) in HPV16/18 type-positive women compared with cytology testing. CerMe performed well in the triage of hrHPV-positive women with ASC-US (sensitivity = 74.4%, specificity = 87.5%) or LSIL cytology (sensitivity = 84.4%, specificity = 83.9%). CONCLUSIONS PCDHGB7 hypermethylation-based CerMe detection can be used as a triage strategy for hrHPV-positive women to reduce unnecessary over-referrals. TRIAL REGISTRATION ChiCTR2100048972.

Abstract
This study investigated the efficacy of the prophylactic human papillomavirus (HPV) vaccine, which was initiated between 2009 and 2013 in Japan. The study involved 1529 eligible women aged 16-39 years who visited 11 outpatient clinics in Japan for various reasons. These patients underwent HPV genotype analysis and a Pap test of cervical cell samples. A total of 299 women (19.6%) had received the prophylactic HPV vaccine (bivalent:quadrivalent vaccine ratio = 2:1). Of the 5062 participants in the Japanese Human Papillomavirus Disease Education and Research Survey (J-HERS 2011), which was conducted in the pre-vaccination era, 3236 eligible participants were included as controls. In this study (J-HERS 2021), the highest rate of HPV vaccination (53%) was observed in patients aged 22-27 years. Vaccinated individuals exhibited a 49% rate of protection against low-grade intraepithelial lesions (LSILs) and atypical squamous cells, not excluding high-grade squamous intraepithelial lesions (ASCH) or worse (LSIL/ASCH+), and a 100% rate of protection against high-grade squamous intraepithelial lesions (HSILs) or worse (HSIL+). Significant reductions in HPV16 (95%) and HPV18 (100%) infections were noted, but no differences were observed in HPV6 and HPV11 infections. The prevalences of HPV51 and HPV59 increased with vaccination, although these changes were not confirmed in the comparative study with J-HERS 2011. Comparing the prevaccination (J-HERS 2011) and postvaccination (J-HERS 2021) periods, 43%, 51%, 88%, and 62% reductions in HPV16, HPV18, HPV16/18, and HPV31/58 infection rates were observed, respectively. Similarly, 62% and 71% reductions in LSIL/ASCH+ and HSIL+ rates were noted, respectively. There were 88% and 87% reductions in LSIL/ASCH+ and HSIL+ rates in 16-21- and 28-33-year-old patients, respectively. Bivalent or quadrivalent vaccines provided 100% protection against high-grade squamous cell lesions (suggestive of CIN2 or CIN3) in young women aged <39 years at 9-12 years after initiation of Japan's first nationwide HPV vaccination program. Cross-protection against HPV31 and HPV58 is likely to occur, although some HPV-type replacements are inconsistent across vaccination regimens. This demonstrates the effectiveness of the HPV vaccine. However, continuous monitoring of cervical cancer and precancer is necessary in younger generations (born 1997-2007), who were rarely vaccinated due to the prolonged suspension of the vaccine recommendations in Japan.

Abstract
OBJECTIVE To compare the clinical efficacy and safety of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) and surgery in treating vaginal high-grade squamous intraepithelial lesions (HSIL) after hysterectomy due to cervical cancer (CC) or precancerous lesions. METHODS A retrospective study was performed comprising 41 women with histologically confirmed vaginal HSIL after hysterectomy for CC or cervical HSIL. Patients were treated with surgery or ALA-PDT and were followed up at 3, 6 and 12 months and then every six months afterwards. Clinical data were collected and the efficacy and safety of the two groups were analyzed. RESULTS Of the 41 patients with vaginal HSIL after hysterectomy, 18 were treated with ALA-PDT and 23 underwent surgery. There was no significant difference in the lesions' complete remission (CR) rate or the human papillomavirus (HPV) clearance rate between the ALA-PDT group and the surgery group (P > 0.05). In the surgery group, the clearance rate of HPV16/18 was higher than that of other high-risk HPV (HR-HPV) and HPV16/18 combined with other HR-HPV (87.50 % vs. 45.45 % vs. 0.00 %, P = 0.014). No significant difference in the recurrence rate between the two groups was noted (P > 0.05). And none of the patients progressed. In the surgery group, one patient developed significant thickening of the vaginal stump, and one patient had increased vaginal discharge. In women treated with ALA-PDT, there was no vaginal bleeding or harmful effects on the organizational structure or functions compared to the surgery group. CONCLUSIONS The efficacy of ALA-PDT was comparable to that of surgery in treating vaginal HSIL following hysterectomy due to CC or cervical HSIL, with fewer side effects.

Abstract
OBJECTIVE HR-HPV types 16 and 18 are responsible for pre-invasive and invasive lesions of the cervix, accounting for 70-80% of the total subtypes. The aim of this study was to investigate the prevalence of high-risk HPV subtypes 16 and 18 in self-collected vaginal samples using real-time micro-PCR and to study the acceptability of self-sampling. METHODS Eligible women (30-65 years) were screened from a semi-urban area of Uttarakhand (India) using self-sampling. High-risk HPV genotypes (16/31 and 18/45) were tested using real-time micro-PCR technique with results available in one hour. The positive results were validated by standard RT-PCR for high-risk HPV 16, 18, separately and for 12 other high-risk genotypes, combined. Ease of the procedure, level of comfort, and recommendation to other women were studied and the acceptability of self-sampling was analyzed using the Likert scale. RESULT Of 975 eligible women screened, 45 participants tested positive for HR-HPV (16/31,18/45) using real-time micro-PCR with a prevalence of 4.6%. Positive samples were further tested through routine RT-PCR and 60% were found to be HR-HPV 16 and 18 positive. For self-sampling, 96.72% (n=943) participants were 'very satisfied' and 94.15% (n=918) found self-sampling to be 'very comfortable' and 88.51% (n=863) stated that they will strongly recommend this test to other eligible women in the community. CONCLUSION We conclude that HR-HPV testing with limited genotyping showed a prevalence of 4.6%, 60% of these were HPV 16/18 positive. Point of care testing was feasible in the community and self-sampling was acceptable.

Abstract
Background This longitudinal cohort study describes the kinetics in antibody levels after two doses of the bivalent human papillomavirus (HPV) vaccine in girls (birth cohort 2001) vaccinated in the routine Dutch vaccination program at 12 years of age, up to 7.5 years post-vaccination. Also, the antibody response one month post-vaccination of the first cohort of boys (birth cohort 2012, vaccinated at 10 years of age) eligible for HPV vaccination in the Netherlands is presented. Method Blood samples and questionnaire data were collected of girls and boys. HPV type-specific antibody concentrations (LU/mL) against HPV16/18/31/33/45/52/58 were assessed using a validated virus-like particle (VLP) multiplex immunoassay. For girls, antibody decays over time were modelled using the modified power-law decay model and the exponential decay model. Results The Geometric Mean Concentrations (GMCs) remained higher for HPV16/18 than for HPV types 31, 33, 45, 52, and 58 among girls up to 7.5 years post-vaccination. The antibody levels of HPV16 and HPV18 reached plateau values of 482 and 159 LU/mL, respectively. Mathematical modelling showed that the half-life values of HPV16/18 were 2.4- to 4.5-fold higher compared with the half-life values of the other HPV types. Among boys (aged 10 years), the GMC for HPV16 was significantly higher than among girls one month post-vaccination (aged 12 years). Conclusion The GMCs of all HPV types declined over time, although the GMCs of HPV16/18 remained relatively high up to 7.5 years post-vaccination. The GMCs for HPV16/18 among boys were at least equally high as the GMCs among girls at one month post-vaccination. Further follow-up of the cohort of boys is needed to gain knowledge on long-term immune responses of young boys following bivalent HPV vaccination.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination programs are a key intervention in protecting individuals against HPV-related disease. HIV1-infected individuals are at increased risk of HPV-associated cancers. This study was conducted to evaluate the potential role of prophylactic HPV vaccines in preventing new HPV infections among participants with perinatally acquired HIV who received the quadrivalent HPV vaccine at least five years before this study. METHODS This cross-sectional study was conducted at Newlands Clinic, Harare, Zimbabwe. The clinic provided the Gardasil quadrivalent HPV vaccine (4vHPV) to 624 adolescents living with HIV starting in December 2015. Vaginal and penile swabs were collected and tested for HPV types from the study participants who had received the 4vHPV vaccine 5-6 years before enrolment. RESULTS We present the results of 98 participants (44.6% female) vaccinated at a median age of 15 years (IQR 12-16). The mean amount of time since vaccination was 6 years (SD: ±0.4). The HPV-positive rate amongst the analyzed swabs was 69% (68/98). Among 30/98 (31%) HPV-positive participants, 13/98 (13%) had low-risk HPV types, and 17/98 (17%) had high-risk HPV types. Twelve participants tested positive for HPV18, only one participant tested positive for HPV16, and an additional four (4.3%) tested positive for either type 6 or 11, with respect to vaccine-preventable low-risk HPV types. CONCLUSION The Gardasil quadrivalent HPV vaccine (4vHPV) was expected to protect against infection with HPV types 16, 18, 6, and 11. We demonstrated a possible waning of immunity to HPV18 in 17% of the participants, and an associated loss in cross-protection against HPV45. We observed a relatively high prevalence of 'opportunistic non-vaccine HPV types' or 'ecological niche occupiers' in this cohort, and suggest further research on the involvement of these types in cervical and other genital cancers. Our study is one of the few, if not the first, to report on HPV vaccine immunoprotection among people living with HIV (PLWH), thereby setting a baseline for further studies on HPV vaccine effectiveness among PLWH.

Abstract
BACKGROUND This study aimed to investigate the epidemiology of high-risk human papillomavirus (HPV) in the female population in Beijing, China, and identify the relationship between HPV genotypes and host factors. METHODS HPV testing was performed on women aged 15-89 (mean age 38.0 ± 10.9 years) from Beijing in 2020. High-risk HPV genotyping real-time polymerase chain reaction was used to determine HPV genotypes. The overall prevalence, age-specific prevalence, genotype distribution, and the correlation between HPV genotypes and cervical cytology were analyzed. RESULTS Among the 25,344 study participants, the single and double infection rates were 18.8% (4,777/25,344) and 4.2% (1,072/25,344), respectively. A total of 6,119 HPV-positive individuals were found to have 91.6% negative results for intraepithelial lesion or malignancy (NILM), 5.8% atypical squamous cells of undetermined significance (ASC-US), 0.9% low-grade squamous intraepithelial lesion (LSIL), and 1.7% high-grade squamous intraepithelial lesion (HSIL). In single HPV infections, the HPV16 genotype was highly associated with cervical cytology severity (χ2 trend = 172.487, P < 0.001). Additionally, HPV infection rates increased gradually with age, and statistical differences were observed across age groups (χ2 = 180.575; P < 0.001). High-risk HPV genotypes were highly prevalent in women below 25 years of age and those aged 55-59 years. Cluster analysis revealed that the 13 HPV genotypes could be roughly divided into two groups in a single infection; however, patterns of infection consistent with biological characteristics were not observed. CONCLUSION High-risk HPV was found in 24.1% of outpatients, with HPV52, HPV58, HPV16, HPV39, and HPV51 being the most common high-risk genotypes. Single high-risk HPV infection was predominant. HPV16, HPV39, HPV51, and HPV52 were associated with cervical lesion progression. HPV16 infection was especially worrying since it aggravates cervical lesions. Because the infection rates of the 13 HPV genotypes differed by age, the peak HPV infection rate should not guide vaccination, screening, and prevention programs. Instead, these initiatives should be tailored based on the regional HPV distribution characteristics. Moreover, it was determined that Beijing's populace needed to receive treatment for HPV39 infection.

Abstract
This study aimed to identify microRNAs (miRNAs) whose expression levels are altered by high-risk human papillomavirus (HR-HPV) infection in women with epithelial ovarian neoplasms. MiRNA expression was quantified by real-time polymerase chain reaction, while HR-HPV DNA was quantified using digital-droplet PCR. Analysis of 11 miRNAs demonstrated significantly lower hsa-miR-25-5p expression in HPV-infected compared to uninfected ovarian tissues (p = 0.0405), while differences in miRNA expression in corresponding serum were statistically insignificant. The expression of hsa-miR-218-5p in ovarian tumors was significantly higher in high-grade serous ovarian carcinoma (HGSOC) cases than in other neoplasms (p = 0.0166). In addition, hsa-miR-218-5p was significantly upregulated, whereas hsa-miR-191-5p was significantly downregulated in tissues with stage III/IV FIGO (p = 0.0009 and p = 0.0305, respectively). Using unsupervised clustering, we identified three unique patient groups with significantly varied frequencies of HPV16/18-positive samples and varied miRNA expression profiles. In multivariate analysis, high expression of hsa-miR-16-5p was an independent prognostic factor for poor overall survival (p = 0.0068). This preliminary analysis showed the changes in miRNA expression in ovarian neoplasms during HPV infection and those collected from HGSOCs or patients with advanced disease. This prospective study can provide new insights into the pathogenesis of ovarian neoplasms and host-virus interactions.

Abstract
BACKGROUND More than 95% of cervical cancers and their precancerous lesions are caused by human papillomavirus (HPV). Cell-free (cf) HPV DNA detection in blood samples may serve as a monitoring tool for cervical cancer. METHODS In our methodological study, an HPV panel for simultaneous detection of 24 types using mass spectrometry-based analysis was developed for liquid biopsy approaches and tested on HPV positive cell lines, plasmid controls, and cervical high-grade squamous intraepithelial lesions (HSIL) in positive smear samples (n = 52). It was validated in cfDNA blood samples (n = 40) of cervical cancer patients. RESULTS The HPV panel showed proficient results in cell lines and viral plasmids with a limit of detection of 1 IU (international units)/µL for HPV16/18 and 10GE/µL for HPV11/31/33/39/45/51/52/58/59 and a specificity of 100% for the tested HPV types. In cervical smear samples, HPV DNA was detected with a sensitivity of 98.14%. The overall agreement between the new HPV panel and clinical records was 97.2% (κ = 0.84). In cervical cancer cfDNA, 26/40 (65.0%) tested positive for any HPV type, with most infections due to hrHPV (24/26). HPV positive samples were found in all FIGO stages, with the highest positivity ratio in FIGO III and IV. Even the lowest stage, FIGO I, had 12/23 (52.2%) patients with a positive HPV plasma status. CONCLUSIONS This proof-of-concept paper shows that the described assay produces reliable results for detecting HPV types in a multiplex mass spectrometry-based assay in cervical smear and cfDNA with high specificity and sensitivity in both cohorts. The assay shows potential for liquid biopsy-based applications in monitoring cervical cancer progression.

Abstract
OBJECTIVE We examined the effectiveness of a behavioral intervention in promoting cervical cancer screening among women living with HIV (WLWH) in Ghana. METHODS A Mixed-methods study was conducted involving 83 WLWH, who were randomly assigned to an intervention group (n = 42) to receive voice-recorded messages based on the 3 R model (Reframing, Reprioritizing, and Reforming) or a control group (n = 41) to receive standard care. The primary outcomes were screening uptake and HPV prevalence. Other outcomes were the acceptability, appropriateness, and feasibility of the intervention. RESULTS The intervention group had a 100% screening rate, and the control group had a 14.63% screening rate. The prevalent rate of high-risk (hr)-HPV genotypes among the women was 67.5% (95%C.I: 0.56-0.77). Over 48% of the participants had multiple hr-HPV genotypes, 64.29% had HPV16/18/45%, and 73.21% had HPV 31/33/45/52/58. Of the women (89.30%) who screened positive, 60% of them were diagnosed and treated for pre-cancer lesions. The intervention messages were acceptable (encourage proactive behavior), feasible (simple, easy to understand), and appropriate (helpful, informative). Facilitators and barriers to self-sampling were identified. CONCLUSION Combining the 3 R model with self-sampling increases cervical cancer screening among WLWH. PRACTICE IMPLICATION Healthcare professionals and policymakers can use this model to increase cervical cancer screening.

Abstract
BACKGROUND Human papillomavirus (HPV) infection contributes to approximately 5% of the worldwide cancer burden. The three-dose HPV vaccine has demonstrated immunogenicity and efficacy. Humoral responses may be critical for preventing, controlling, and/or eliminating HPV infection. Using data from the HITCH cohort, we analysed humoral immune response to HPV vaccination among women in relation to the phylogenetic relatedness of HPV genotypes. METHODS We included 96 women aged 18-24 years attending college or university in Montreal, Canada. Participants provided blood samples at enrolment and five follow-up visits. Antibody response to bacterially expressed L1 and E6 glutathione S-transferase fusion proteins of multiple Alphapapillomavirus types, and to virus-like particles (VLP-L1) of HPV16 and HPV18 were measured using multiplex serology. We assessed correlations between antibody seroreactivities using Pearson correlations (r). RESULTS At enrolment, 87.7% of participants were unvaccinated, 2.4% had received one, 3.2% two, and 6.7% three doses of HPV vaccine. The corresponding L1 seropositivity to any HPV was 41.2%, 83.3%, 100%, and 97.0%. Between-type correlations for L1 seroreactivities increased with the number of vaccine doses, from one to three. Among the latter, the strongest correlations were observed for HPV58-HPV33 (Pearson correlation [r] = 0.96; α9-species); HPV11-HPV6 (r = 0.96; α10-species); HPV45-HPV18 (r = 0.95; α7-species), and HPV68-HPV59 (r = 0.95; α7-species). CONCLUSIONS Correlations between HPV-specific antibody seroreactivities are affected by phylogenetic relatedness, with anti-L1 correlations becoming stronger with the number of vaccine doses received.

Abstract
Human papillomavirus (HPV) infection can lead to HPV-related cancer in men, including the anus, penile, and oropharyngeal cancers and precancerous lesions. This study retrospectively investigated HPV prevalence and genotype distribution in Liaocheng men between 2016 and 2022. The total HPV positive rate was 64.87% (2388/3681, 95% confidence interval [CI]: 63.32%-66.40%), where high risk (HR)-HPV and low risk (LR)-HPV accounted for 42.49% (1564/3681, 95% CI: 40.90%-44.09%) and 69.71% (2566/3681, 95% CI: 68.20%-71.17%), respectively. The mixed HPV infection rate of two and more genotypes was 35.72%. The infection rate of HR-HPV increased with the number of positive cases annually from 2016 (16.91%) to 2022 (46.59%). The most common HR-HPV genotypes were HPV16 (11.60%), HPV52 (6.95%), and HPV59 (6.28%), whereas the least common HR-HPV was HPV26. The most common LR-HPV genotypes were HPV6 (56.99%), HPV11 (23.79%), and HPV43 (6.37%). The 9 v HPV vaccine preventable for LR-HPV and HR-HPV accounted for 80.78% and 30.40%, respectively, in this study. Most HPV-positive patients aged 1-86 were in the 30-39 age group. This study confirmed that HPV prevalence in Liaocheng men was common and diverse. HPV16, HPV52, and HPV59 are widely distributed in Liaocheng men, and the male HR-HPV infection rate remained high in this region. Regarding public health and cancer prevention, it is recommended and effective to include the HPV vaccination in the national vaccination program for men.

Abstract
Human papillomavirus (HPV) infection is associated with the risk of developing certain cancers, including cancers of the cervix, vulva, vagina, penis, anus, rectum, and oropharynx. In 2016, the bivalent HPV-16/18 vaccine was included in the Korea National Immunization Program. This vaccine protects against HPV types 16 and 18 and other oncogenic HPV types predominant in cervical and anal cancers. This post-marketing surveillance (PMS) study assessed the safety of the HPV-16/18 vaccine in Korea. The study was conducted in males and females aged between 9 and 25 years, from 2017 to 2021. Safety was measured in terms of frequency and intensity of adverse events (AEs), adverse drug reactions (ADRs), and serious adverse events (SAEs) after each vaccine dose. The safety analysis included all participants who were vaccinated as per prescribing information and who completed a 30-day follow-up after at least one dose. Data were collected using individual case report forms. The total safety cohort included 662 participants. A total of 220 AEs were reported in 144 subjects (21.75%), and there were 158 ADRs in 111 subjects (16.77%), with the most common being injection site pain in all cases. No SAEs or serious ADRs were reported. Most AEs were reported after the first dose and were injection site reactions with mild intensity that recovered. No individuals required hospitalization or an emergency department visit. Safety results showed that the HPV-16/18 vaccine was generally well tolerated in the Korean population, and no safety concerns were identified.ClinicalTrials.gov Identifier: NCT03671369.

Abstract
Long-term follow-up of a cohort of unmarried girls who received one, two, or three doses of quadrivalent HPV vaccine, between 10 and 18 years of age, in an Indian multi-centric study allowed us to compare antibody responses between the younger and older age cohorts at 10-years post-vaccination, and study the impact of initiation of sexual activity and cervical HPV infections on antibody levels. Among the younger (10-14 years) recipients of a single dose, 97.7% and 98.2% had detectable binding antibody titers against HPV 16 and HPV 18 respectively at ten years post-vaccination. The proportions among those receiving a single dose at age 15-18 years were 92.3% and 94.2% against HPV 16 and HPV 18 respectively. Mean HPV 16 binding antibody titers were 2.1 folds (95%CI 1.4 to 3.3) higher in those vaccinated at ages 10-14 years, and 1.9 folds (95%CI 1.2 to 3.0) higher in those vaccinated at 15-18 years compared to mean titers seen in the unvaccinated women. Compared to previous timepoints of 36 or 48 months, binding antibodies against HPV 16 and neutralizing antibodies against both HPV 16 and HPV 18 were significantly higher at 10 years. This rise was more pronounced in participants vaccinated at 15-18 years. No association of marital status or cervical HPV infections was observed with the rise in titer. Durability of antibody response in single dose recipients correlated well with the high efficacy of a single dose against persistent HPV 16/18 infections irrespective of age at vaccination, as we reported earlier.

Abstract
BACKGROUND Advanced penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy with limited success of immune-checkpoint inhibitors (ICIs). Approximately half of pSCC cases are associated with human papillomavirus (HPV) infection. METHODS Evaluation was done retrospectively of the landscape of somatic alterations and ICI-related biomarkers in pSCC by using the Caris Life Sciences data set with the aim to establish signatures for HPV-dependent oncogenesis. The pSCC tumors were analyzed by using next-generation sequencing (NGS) of DNA and RNA. Programmed death ligand 1 (PD-L1) expression was evaluated by immunohistochemistry (IHC). Microsatellite instability (MSI) was tested by fragment analysis, IHC (SP142; ≥1%), and NGS. Tumor mutational burden (TMB)-high was defined as ≥10 mutations/Mb. HPV16/18 status was determined by using whole-exome sequencing (WES) when available. Significance was adjusted for multiple comparisons (q value < .05). RESULTS NGS of the overall cohort (N = 108) revealed TP53 (46%), CDKN2A (26%), and PIK3CA (25%) to be the most common mutations. Overall, 51% of tumors were PD-L1+, 10.7% had high TMB, and 1.1% had mismatch repair-deficient (dMMR)/MSI-high status. Twenty-nine patients had their HPV status made available by WES (HPV16/18+, n = 13; HPV16/18-, n = 16). KMT2C mutations (33% vs. 0%) and FGF3 amplifications (30.8% vs. 0%) were specific to HPV16/18+ tumors, whereas CDKN2A mutations (0% vs. 37.5%) were exclusive to HPV16/18- tumors. TMB-high was exclusively found in the HPV16/18+ group (30.8%). The two groups had comparable PD-L1 and dMMR/MSI-H status. CONCLUSIONS In a large and comprehensive NGS-based evaluation of somatic alterations in pSCC, HPV16/18+ versus HPV16/18- pSCCs were molecularly distinct tumors. Our finding that TMB-high is exclusive to HPV16/18+ tumors requires confirmation in larger data sets. PLAIN LANGUAGE SUMMARY Penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy in the advanced setting, with poor prognosis and little success with immune-checkpoint inhibitors (ICIs) in an unselected patient approach. Human papillomavirus (HPV) infection is a known risk factor for pSCC; its impact on genomic tumor profiling is less defined. Using next-generation sequencing, we explored the genetic landscape and ICI-related biomarkers of pSCC and HPV-driven oncogenic molecular signatures. Our results indicate that HPV-positive and HPV-negative pSCCs are molecularly distinct tumors. Increased tumor mutational burden is associated with HPV-positive tumors, and could serve as a biomarker for predicting therapeutic response to ICI-based therapies. Our results support the growing literature indicating that HPV status in pSCC can be used to guide patient stratification in ICI-based clinical trials.

Abstract
The aims of this study on human papilloma virus (HPV) 6/11/16/18 infection among females in Chengdu were to provide more targeted strategies for the prevention and treatment of cervical cancer and genital warts. In this study, the infection status of 20 genotypes was analysed by gene chip technology. The prevalence rates of HPV-6, -11, -16, and -18 infection among 180,276 cases were 0.94%, 0.57%, 3.22%, and 1.28%, respectively. The prevalence of HPV 6/11/16/18 showed a bimodal U-shaped curve with age; the first and second peak occurred among females < 20 and ≥ 60 years old, respectively. As the multiplicity of infections involving HPV6/11/16/18 increases, the infection rate decreases. The ratios of HPV16 single infection showed a yearly increase. The top five genotypes with HPV-16, -18, -6, and -11 in coinfection were HPV52/58/53/51/33, HPV 52/16/53/58/51, HPV52/16/58/51/53 and HPV16/52/58/59/18, respectively, HPV16/18/6/11 were mainly coinfected with HR-HPV. In sum, among the five vaccines available, nonavalent vaccine is more suitable for Chengdu females. For young females prioritizing vaccination is essential in the current context, while HPV screening remains an effective approach for older females. Additionally, in patients with genital warts, it is necessary to assess the presence of high-risk HPV infection and manage it appropriately in patients with genital warts.

Abstract
BACKGROUND The detection and continuous monitoring of low-grade squamous intraepithelial lesions (LSIL) within the endocervical canal pose considerable challenges, and the effectiveness of ablation treatment is also constrained. In this context, the potential efficacy of 5-aminolevulinic acid photodynamic therapy (5-ALA PDT) in targeting these concealed lesions merits exploration. The present study undertakes a comprehensive analysis of the clinical effectiveness and safety aspects associated with the utilization of 5-ALA PDT. METHODS A retrospective analysis was conducted on a cohort of 13 patients who were diagnosed with LSIL within the endocervical canal, concomitant with high-risk human papillomavirus (hrHPV) infection. These patients were subjected to treatment with 5-ALA PDT and subsequently monitored over a period of 3-6 months following the intervention. RESULTS The study cohort comprised 13 patients, among whom 4 presented with isolated lesions within the endocervical canal, 5 exhibited LSIL involving both the endocervical canal and the cervix vaginal portion, 3 displayed LSIL within the endocervical canal in conjunction with vaginal involvement, and 1 patient demonstrated lesions across all three of these anatomical sites. All identified lesions underwent therapeutic intervention via 5-ALA PDT. Before treatment initiation, 9 patients returned positive results in the liquid-based cytologic test (LBC), 4 displayed concurrent multiple hrHPV infections, and 5 manifested infections specifically with HPV 16/18. Subsequent to the application of 5-ALA PDT, regression was observed in the LBC results of all patients, with only 3 individuals retaining a singular type of hrHPV infection. Adverse reactions following treatment encompassed mild aberrant vaginal secretions and mild to moderately pronounced distending abdominal discomfort, all of which were remitted within a span of 7 days. CONCLUSIONS Within the context of LSIL within the endocervical canal in association with hrHPV infection, the findings affirm the efficacy and safety of 5-ALA PDT as a viable therapeutic modality.

Abstract
Cervical cancer burden is high where prophylactic vaccination and screening coverage are low. We demonstrated in a multicenter randomized, double-blind, controlled trial that single-dose human papillomavirus (HPV) vaccination had high vaccine efficacy (VE) against persistent infection at 18 months in Kenyan women. Here, we report findings of this trial through 3 years of follow-up. Overall, 2,275 healthy women aged 15-20 years were recruited and randomly assigned to receive bivalent (n = 760), nonavalent (n = 758) or control (n = 757) vaccine. The primary outcome was incident-persistent vaccine type-specific cervical HPV infection. The primary evaluation was superiority analysis in the modified intention-to-treat (mITT) HPV 16/18 and HPV 16/18/31/33/45/52/58 cohorts. The trial met its prespecified end points of vaccine type-specific persistent HPV infection. A total of 75 incident-persistent infections were detected in the HPV 16/18 mITT cohort: 2 in the bivalent group, 1 in the nonavalent group and 72 in the control group. Nonavalent VE was 98.8% (95% CI 91.3-99.8%, P < 0.0001) and bivalent VE was 97.5% (95% CI 90.0-99.4%, P < 0.0001). Overall, 89 persistent infections were detected in the HPV 16/18/31/33/45/52/58 mITT cohort: 5 in the nonavalent group and 84 in the control group; nonavalent VE was 95.5% (95% CI 89.0-98.2%, P < 0.0001). There were no vaccine-related severe adverse events. Three years after vaccination, single-dose HPV vaccination was highly efficacious, safe and conferred durable protection. ClinicalTrials.gov no.

Abstract
BACKGROUND To meet global cervical cancer elimination efforts, a wider range of affordable and accessible vaccines against human papillomavirus (HPV) are needed. We aimed to evaluate the immunogenicity and safety of a quadrivalent HPV vaccine (targeting HPV types 6, 11, 16, and 18), developed and manufactured by the Serum Institute of India (SIIPL). Here we report outcomes in the 9-14 years cohort. METHODS This randomised, active-controlled, phase 2/3 trial was conducted at 12 tertiary care hospitals across India. Healthy participants aged 9-14 years or 15-26 years with no history of HPV vaccination were eligible for enrolment. Female participants were randomly assigned (1:1) with an interactive web response system, by use of a central computer-generated schedule and block randomisation (block sizes of 2, 4, 6, and 8), to receive the SIIPL quadrivalent HPV vaccine (Cervavac; SIIPL, Pune, India) or the comparator quadrivalent HPV vaccine (Gardasil; Merck Sharp & Dohme, Harleem, the Netherlands). Participants, investigators, laboratory technicians, and sponsors were masked to treatment allocation of female participants. Male participants were given the SIIPL quadrivalent HPV vaccine in an open-label manner. Study vaccines were administered intramuscularly with a two-dose schedule (at day 0 and 6 months) in the cohort aged 9-14 years, and with a three-dose schedule (at day 0, month 2, and month 6) in the cohort aged 15-26-years. Immunogenicity was assessed 30 days after the last dose by use of multiplexed ELISA. The primary outcome was the non-inferiority of immune response in terms of the geometric mean titre (GMT) of antibodies against HPV types 6, 11, 16, and 18 generated by the SIIPL quadrivalent HPV vaccine in girls and boys (aged 9-14 years) compared with the GMT generated by the comparator quadrivalent HPV vaccine in women aged 15-26 years at month 7 in the modified per-protocol population (ie, all participants who received all doses of study vaccines per assigned treatment group and had both day 0 and 1-month immunogenicity measurements after the last dose following protocol-defined window periods with no major protocol deviations). Non-inferiority was established if the lower bound of the 98·75% CI of the GMT ratio was 0·67 or higher. The co-primary outcome of occurrence of solicited adverse events (within 7 days of each dose) and unsolicited adverse events (up to 30 days after the last dose) was assessed in all participants who were enrolled and received at least one dose of study vaccine. The trial is registered with the Clinical Trials Registry - India (CTRI/2018/06/014601), and long-term follow-up is ongoing. FINDINGS Between Sept 20, 2018, and Feb 9, 2021, 2341 individuals were screened, of whom 2307 eligible individuals were enrolled and vaccinated: 1107 (738 girls and 369 boys) in the cohort aged 9-14 years and 1200 (819 women and 381 men) in the cohort aged 15-26 years. No race or ethnicity data were collected. 350 girls and 349 boys in the SIIPL quadrivalent HPV vaccine group and 338 women in the comparator vaccine group were included in the modified per-protocol population for the primary endpoint analysis. The median follow-up for the analyses was 221 days (IQR 215-231) for girls and 222 days (217-230) for boys in the SIIPL quadrivalent HPV vaccine group, 223 days (216-232) for girls in the comparator vaccine group, and 222 days (216-230) for women in the comparator vaccine group. GMT ratios were non-inferior in girls and boys receiving the SIIPL quadrivalent HPV vaccine compared with women receiving the comparator vaccine: GMT ratios for girls were 1·97 (98·75% CI 1·67-2·32) for HPV type 6, 1·63 (1·38-1·91) for HPV type 11, 1·90 (1·60-2·25) for HPV type 16, and 2·16 (1·79-2·61) for HPV type 18. For boys the GMT ratios were 1·86 (1·57-2·21) for HPV type 6, 1·46 (1·23-1·73) for HPV type 11, 1·62 (1·36-1·94) for HPV type 16, and 1·80 (1·48-2·18) for HPV type 18. The safety population comprised all 1107 participants (369 girls and 369 boys in the SIIPL quadrivalent HPV vaccine group, and 369 girls in the comparator group). Solicited adverse events occurred in 176 (48%) of 369 girls and 124 (34%) of 369 boys in the SIIPL vaccine group and 179 (49%) of 369 girls in the comparator vaccine group. No grade 3-4 solicited adverse events occurred within 7 days of each dose. Unsolicited adverse events occurred in 143 (39%) girls and 147 (40%) boys in the SIIPL vaccine group, and 143 (39%) girls in the comparator vaccine group. The most common grade 3 unsolicited adverse event was dengue fever, in one (<1%) girl in the SIIPL vaccine group and three (1%) girls in the comparator group. There were no grade 4 or 5 adverse events. Serious adverse events occurred in three (1%) girls and three (1%) boys in the SIIPL vaccine group, and five (1%) girls in the comparator vaccine group. No vaccine-related serious adverse events were reported. There were no treatment-related deaths. INTERPRETATION We observed a non-inferior immune response with the SIIPL quadrivalent HPV vaccine in girls and boys aged 9-14 years and an acceptable safety profile compared with the comparator vaccine. These findings support extrapolation of efficacy from the comparator vaccine to the SIIPL quadrivalent HPV vaccine in the younger population. The availability of the SIIPL quadrivalent HPV vaccine could help meet the global demand for HPV vaccines, and boost coverage for both girls and boys globally.

Abstract
BACKGROUND Sexually transmitted infections, specifically Chlamydia trachomatis (CT), may be associated with epithelial ovarian cancer (EOC) risk. The association between CT and EOC subtypes is unclear. Our aim was to investigate whether history of CT and other infections (Mycoplasma genitalium [MG], herpes simplex virus type 2 [HSV-2], and human papillomavirus [HPV]) are associated with EOC risk by histotype. METHODS We measured antibodies (Abs) to CT, MG, HSV-2, and HPV-16/18 in serum samples in a nested case-control study in the Finnish Maternity Cohort (N = 484 cases 1:1 matched to controls). Logistic regression was used to calculate relative risks (RRs) and 95% confidence intervals (CIs) in seropositive versus seronegative individuals in all cases, as well as serous (n = 249), clear cell and endometrioid (n = 91), and mucinous (n = 144) EOC. RESULTS CT seropositivity was not associated with EOC risk (eg, CT pGP3-Ab: RR, 0.92 [95% CI, .72-1.19]), regardless of disease subtype. We observed a positive association between MG seropositivity and mucinous EOC (RR, 1.66 [95% CI, 1.09-2.54]; P for heterogeneity by histotype ≤ .001), but not other subtypes. No associations were observed with seropositivity to multiple STIs. CONCLUSIONS CT infection was not associated with EOC risk, with associations observed only for MG and mucinous EOC. Mechanisms linking MG to mucinous EOC remain to be elucidated.

Abstract
The long-term effect of population-level human papillomavirus (HPV) vaccination on the viral ecology of the untargeted HPVs is poorly understood. We performed an 8-year follow-up of 33 communities randomized to gender-neutral HPV16/18 vaccination, girls-only HPV16/18 vaccination, and control communities without HPV vaccination. The 1992/93 and 1994 birth cohorts were invited in school years 2007/8 and 2008/9. Follow-up cervico-vaginal sampling at 18 and 22 years of age, 4 and 8 years post-vaccination, respectively, were attended by 11,396 and 5,602 participants. HPV types 6/11/16/18/31/33/35/39/45/51/52/56/58/59/66/68 were genotyped and used for the community-level ecological diversity estimations. Gender-neutral vaccination communities with a stronger herd immunity than girls-only vaccination communities show a significantly increased HPV α-diversity (p = 1.1 × 10-8) from 4 to 8 years post-vaccination, despite the clearance of the vaccine-targeted HPVs in these communities. This likely sign of niche occupation by the non-vaccine-targeted HPVs will potentially affect the future cervical cancer screening programs but should not interfere with the WHO mission to eliminate cervical cancer.

Abstract
Objective To investigate the expression of E7 protein and its relationship with the progression and prognosis of cervical pre-cancerous lesions in patients with human papillomavirus (HPV) 16/18 infections. Methods A total of 211 patients with positive HPV 16/18 were included in this study. Patients were categorized into three groups based on colposcopy results: NILM (Negative for Intraepithelial Lesion or Malignancy), LSIL (Low-Grade Squamous Intraepithelial Lesion), and HSIL (High-Grade Squamous Intraepithelial Lesion). E7 protein levels were quantified using Immunochromatographic Assay and compared using ANOVA. Cervical E7 protein levels were assessed before and one year after cervical cone biopsy in the HSIL group. Results Among HPV 16/18-positive patients with normal Cervical Thinprep Cytologic Test (TCT) results, E7 protein content exhibited abnormal and significant values (P = .001). Mean E7 protein levels for the NILM, LSIL, and HSIL groups were 44.52 ng/mL, 114.60 ng/mL, and 389.20 ng/mL, respectively, and showed statistical significance (P = .000). In the HSIL group, E7 protein levels in HPV-negative patients were significantly lower one year after cervical cone biopsy compared to before (P = .001). However, HPV-positive patients displayed no significant alteration in E7 protein levels before and after biopsy (P = .08). Conclusions E7 protein levels in detached cervical cells are closely associated with the severity and prognosis of cervical pre-cancerous lesions, suggesting their potential role as a biomarker for monitoring cervical lesion development.

Abstract
The first prophylactic vaccine against human papillomavirus (HPV) 16 and HPV18 was licensed in Japan in 2009. HPV vaccine effectiveness against high-grade cervical lesions has been demonstrated among young Japanese women, but evidence of its effects on invasive cervical cancer (ICC) is lacking. Using data from two different cancer registries, we compared recent trends of new ICC cases by age group using Poisson regression analysis. We also analyzed time trends in HPV16/18 prevalence among 1414 Japanese women aged <40 years newly diagnosed with ICC in the past decade. Based on the population-based cancer registry, the incidence of ICC among young women aged 20-29 years showed a significant decline from 3.6 to 2.8 per 100 000 women-years during 2016-2019, but no similar decline was observed for older age groups (p < 0.01). Similarly, using data from the gynecological cancer registry of the Japan Society of Obstetrics and Gynecology, the annual number of ICCs among women aged 20-29 years also decreased from 256 cases to 135 cases during 2011-2020 (p < 0.0001). Furthermore, a declining trend in HPV16/18 prevalence in ICC was observed only among women aged 20-29 years during 2017-2022 (90.5%-64.7%, p = 0.05; Cochran-Armitage trend test). This is the first report to suggest population-level effects of HPV vaccination on ICC in Japan. Although the declining trend in HPV16/18 prevalence among young women with ICC supports a causal linkage between vaccination and results from cancer registries, further studies are warranted to confirm that our findings are attributable to vaccination.

Abstract
OBJECTIVE The current study aimed to investigate the correlation between HPV16/18 infection and the microecological characteristics of the female reproductive tract and cervical lesions and to explore the risk factors associated with cervical precancerous lesions (CIN) and cervical cancer (CC). METHODS A total of 326 women were selected for HPV screening, with 121 testing negative for HPV, 113 infected with HPV16/18, and 92 infected with other types of HPV. Microecological characteristics of the vaginal flora in all subjects were analyzed. Liquid-based thin layer cell (TCT) tests, genitourinary tract infection pathogen (STDs) assessments, HPV typing, and colposcopic pathological biopsies of exfoliated cervical cells were conducted. RESULTS Among patients with HPV infection, there was a higher detection rate of abnormal microecological indicators such as bacterial vaginosis (BV) and vaginal cleanliness. Additionally, an increased proportion of vaginal microbiota (VM) imbalance was observed. Ureaplasma urealyticum (Uu) infection in the reproductive tract was closely associated with HPV 16/18 infection and showed co-infection. Moreover, patients with BV infection and high expression of HPV mRNA were at a higher risk of persistent HPV16/18 positive infection. BV infection, Uu infection, and HPV16/18 positive infection were identified as risk factors for CIN and CC. Furthermore, BV and Uu infections promoted the development of CIN/CC in patients infected with HPV16/18. CONCLUSIONS Changes in vaginal microecology are strongly linked to HPV16/18 infection. BV infection, Uu infection, HPV viral load, and HPV16/18 infection are risk factors for CIN/CC. Timely treatment of BV and Uu infections, restoration of a normal vaginal microecological environment, and improvement of HPV16/18 outcomes can delay the occurrence and progression of CIN/CC.

Abstract
OBJECTIVE The present study aims to establish a risk profile for high-grade cervical lesions and cervical cancer (CIN2 + ) in women undergoing colposcopy at the Hospital do Câncer de Barretos, through the analysis of Human Papillomavirus (HPV) infection, cervical cytology, and patient's age. METHODS Retrospective cross-sectional study based on a computerized database of women aged ≥ 18 years old who underwent colposcopy at the Prevention Department of the Hospital do Câncer de Barretos from 2017 to 2019. RESULTS A total of 3,411 women were included, 58.0% were positive for high-risk-HPV test, with a higher prevalence of CIN2+ for HPV16 (30.3%) and other HPV (45.0%). Cytological findings that suggest invasive cervical cancer (squamous cells or adenocarcinoma), regardless of the status of HPV test, showed 100% diagnosis of CIN2 + , while atypias that suggest high-grade lesions, HSIL and ASC-H, positive for HPV test, showed in 86 and 55.2%, respectively, diagnosis of CIN2 + . ASC-H cytological results among women aged > 40 years old and negative HPV were mainly associated with benign findings. We observed that ≤ CIN1 has a higher prevalence among older women with negative HPV, while for high-grade lesions there is an increase among young women HPV16- and/or 18-positive. In cancer diagnosis, we observed a predominance of HPV 16/18 regardless of the age group. CONCLUSION The highest risks of precursor lesions and cervical cancer were found among women with positive HPV 16/18 tests and severe cytological atypia in population screening tests. In addition, cytological findings of ASC-H HPV negative in women > 40 years old usually represent benign findings in histological investigation.

Abstract
BACKGROUND We previously reported that REBACIN effectively eliminates persistent high-risk human papillomavirus (hrHPV) infection. Here, we conducted a prospective multicenter cohort study to evaluate the safety and effectiveness of REBACIN, taking into account factors such as specific hrHPV subtype and patient's age. METHODS According to inclusion/exclusion criteria and participant willingness, 3252 patients were divided into REBACIN group while 249 patients into control group. Patients in REBACIN group received one course treatment of intravaginal administration of REBACIN while no treatment in control group. After drug withdrawal, participants in both groups were followed up. RESULTS The clearance rate of persistent hrHPV infection in REBACIN group was 60.64%, compared to 20.08% in control group. Specifically, the clearance rates for single-type infection of HPV16 or HPV18 were 70.62% and 69.23%, respectively, which was higher than that of HPV52 (59.04%) or HPV58 (62.64%). In addition, the single, double, and triple/triple+ infections had a clearance rate of 65.70%, 53.31%, and 38.30%, respectively. Moreover, 1635 patients under 40 years old had a clearance rate of 65.14%, while it was 55.08% for 1447 patients over 40 years old. No serious adverse effects were found. CONCLUSION This study confirmed that REBACIN can effectively and safely eliminate persistent hrHPV infection, which the clearance rate of HPV16/18 is higher than that of HPV52/58, the clearance rate of single-type infection is higher than that of multiple-type infections, and the clearance rate in young patients is higher than that in elder patients, providing a guidance for REBACIN application in clearing hrHPV persistent infection in real-world settings.

Abstract
OBJECTIVE To evaluate how the duration of human papillomavirus (HPV) persistence influences the risk of developing recurrent high-grade cervical dysplasia (CIN2+). METHODS Data of patients with persistent HPV infection (at least at 6 months) after primary conization were extracted from a multi-institutional Italian database, retrospectively. Kaplan-Meier and Cox proportional hazards models were used to evaluate associations between duration of HPV persistence with the 5-year risk of developing recurrent CIN2+. RESULTS Overall, 545 patients met the inclusion criteria. Positive margins were detected in 160 (29.3%) patients. Overall, 247 (45.3%) and 123 (22.6%) patients had a documented infection from HPV16/18, and other high-risk HPV types. 187 (34.3%), 73 (13.4%), and 40 (7.3%) were diagnosed with persistent HPV infection at 12, 18, and 24 months, respectively. Patients with HPV persistence at 6 months experienced a risk of recurrence of 7.46%. Twelve-month HPV persistence strongly correlates with the risk of developing the recurrent disease (risk of recurrence: 13.1%). While, having HPV persistence >12 months did not correlate with an increased risk of recurrence (hazard ratio: 1.34 (95% confidence interval: 0.78-2.32); P = 0.336, log-rank test). CONCLUSION HPV persistence is one of the most important factors predicting the risk of CIN2+ recurrence. The risk of CIN2+ recurrence increased with the increase of HPV persistence for up to 1 year. The persistence of HPV after the first year does not appear as a risk factor.

Abstract
INTRODUCTION The UK national human papillomavirus (HPV) vaccination programme was introduced in 2008 using the bivalent HPV16/18 vaccine, changing to the quadrivalent HPV6/11/16/18 vaccine from 2012. We provide an analysis of type-specific HPV prevalence in young sexually active females in England to end 2020 (when the first routinely HPV vaccinated females were reaching 25 years of age and entering the National Health Service Cervical Screening Programme), showing the impact of over ten years of high coverage HPV vaccination. METHODS Residual vulvovaginal swabs (VVS) were collected from 16 to 24 year old women attending for chlamydia screening between 2010 and 2020, anonymised and tested for type-specific HPV DNA. Trends in vaccine and non-vaccine HPV type prevalence were compared over time and association with vaccination coverage was evaluated within the post-vaccination period. RESULTS A total of 21,168 eligible VVS specimens were tested for HPV DNA. The prevalence of HPV16/18 in sexually active 16-18 year old females who were offered vaccination aged 12-13 years was <1% in the most recent years tested, compared to over 15% prior to the vaccination programme in 2008. The magnitude of these decreases also suggests reduced transmission is offering some herd protection to unvaccinated females. HPV31/33/45 prevalence also steadily decreased, providing evidence of cross-protection. HPV6/11 prevalence remained stable during the bivalent vaccine period, with more recent declines, as expected due to the use of the quadrivalent vaccine. There has been no substantive increase in the prevalence of other high-risk (HR) HPV types. DISCUSSION More than ten years of high coverage HPV vaccination in adolescent females in England has delivered dramatic declines in the prevalence of HPV vaccine-types and closely related HPV types in females in the vaccine eligible age group, and no indication of type replacement. These findings should enable confidence in planning for cervical screening of these females, and in predicting declines in HPV-related cancers.

Abstract
BACKGROUND Human papillomavirus (HPV) viral load (VL) is associated with persistence, which increases cervical cancer risk. The bivalent vaccine protects against oncogenic HPV-16/18 and cross-protects against several nonvaccine types. We examined the effect of 2-dose (2D) and 3-dose (3D) vaccination on HPV prevalence and VL in clearing infections and persistent infections, 6 years and 12 years postvaccination, respectively. METHODS Vaginal swabs collected from the "HPV Amongst Vaccinated and Non-vaccinated Adolescents" study (HAVANA, 3D-eligible) and HAVANA-2 (2D-eligble) participants were genotyped for HPV with the SPF10-DEIA-LiPA25 system. HPV VL was measured with type-specific quantitative polymerase chain reaction (qPCR). RESULTS HPV-16, -18, -31, -33, and -45 clearing and/or persistent infection prevalence and HPV-16, -18, and -31 VLs in clearing infections were significantly reduced in 3D-vaccinated women compared to unvaccinated women. Except for HPV-11 and -59 clearing infections, no significant VL differences were observed among vaccinated women, ≤6 and >6 years post-vaccination. Infection numbers were low in 2D-eligible women, with no HPV-16/18 in vaccinated women. No VL differences for the remaining types were found. CONCLUSIONS 3D vaccination reduces HPV prevalence in clearing infections and persistent infections and decreases HPV VLs in clearing infections, 12 years post-vaccination for vaccine and several nonvaccine types. 2D-eligible women had low infection numbers, with no HPV-16/18 among vaccinated women.

Abstract
BACKGROUND Real-world data (RWD) are increasingly used to generate real-world evidence (RWE) of vaccine safety and effectiveness for regulatory purposes. Assessing feasibility of using RWD sources prior to implementing observational studies is recommended. As a use case, we described the process and findings of a feasibility assessment to identify reliable and relevant data sources for monitoring the safety and effectiveness of the AS04-HPV-16/18 human papillomavirus (HPV) vaccine in China. METHODS Iterative multi-step process: (1) targeted literature review and data source mapping; (2) expert opinion from national RWD experts; (3) survey to evaluate the identified data source operational infrastructure; and (4) continuous appraisal of published studies using the identified data source. RESULTS The Yinzhou Regional Health Information Platform (YRHIP) was identified as a data source of main interest, based on its large population coverage, high cervical cancer screening rates, and availability of adult electronic immunization records. Field meetings with national RWD experts confirmed its suitability for post-authorization vaccine studies. Survey results showed that exposure data and relevant safety and effectiveness endpoints were recorded and linkable at the individual level across the platform. Iterative appraisal of emerging evidence from the literature corroborated these findings. CONCLUSIONS This feasibility assessment indicates that the YRHIP has the capacity to capture demographic, exposure, outcome and other data required to generate RWE on HPV vaccine safety and effectiveness in China. Studies using the YRHIP to monitor the AS04-HPV-16/18 vaccine in routine use building on this feasibility assessment are ongoing.

Abstract
BACKGROUND Cervical screening programs use testing for human papillomavirus (HPV) genotypes. Different HPV types differ greatly in prevalence and oncogenicity. We estimated the impact of cervical screening and follow-up for each HPV type. METHODS AND FINDINGS For each type of HPV, we calculated the number of women needed to screen (NNS) and number of women needing follow-up (NNF) to detect or prevent one cervical cancer case, using the following individual level input data (i) screening and cancer data for all women aged 25 to 80 years, resident in Sweden during 2004 to 2011 (N = 3,568,938); (ii) HPV type-specific prevalences and screening histories among women with cervical cancer in Sweden in 2002 to 2011(N = 4,254); (iii) HPV 16/18/other HPV prevalences in the population-based HPV screening program (N = 656,607); and (iv) exact HPV genotyping in a population-based cohort (n = 12,527). Historical screening attendance was associated with a 72% reduction of cervical cancer incidence caused by HPV16 (71.6%, 95% confidence interval (CI) [69.1%, 73.9%]) and a 54% reduction of cancer caused by HPV18 (53.8%, 95% CI [40.6%, 63.1%]). One case of HPV16-caused cervical cancer could be prevented for every 5,527 women attending screening (number needed to screen, NNS). Prevention of one case of HPV16-caused cervical cancer required follow-up of 147 HPV16-positive women (number needed to follow-up, NNF). The NNS and NNF were up to 40 to 500 times higher for HPV types commonly screened for with lower oncogenic potential (HPV35,39,51,56,59,66,68). For women below 30 years of age, NNS and NNF for HPV16 were 4,747 and 289, respectively, but >220,000 and >16,000 for HPV35,39,51,56,59,66,68. All estimates were either age-standarized or age-stratified. The primary limitation of our study is that NNS is dependent on the HPV prevalence that can differ between populations and over time. However, it can readily be recalculated in other settings and monitored when HPV type-specific prevalence changes. Other limitations include that in some age groups, there was little data and extrapolations had to be made. Finally, there were very few cervical cancer cases associated with certain HPV types in young age group. CONCLUSIONS In this study, we observed that the impact of cervical cancer screening varies depending on the HPV type screened for. Estimating and monitoring the impact of screening by HPV type can facilitate the design of effective and efficient HPV-based cervical screening programs.

Abstract
BACKGROUND Although cervical screening using Human Papillomavirus (HPV) testing is globally recommended public health policy, there has been no international proficiency studies specifically targeting HPV testing for cervical screening. OBJECTIVE To obtain the first global overview of the current proficiency of HPV testing services for cervical cancer screening. STUDY DESIGN A coded proficiency panel of 12 samples containing HPV types 16, 18, 31, 33, 45, 52, 58 or 35/39/51/56/59/68 in human DNA in varying amounts as well as control. Datasets detecting at least a) 10 International Units (IU) of HPV16 and 18, b) 1000 IU of HPV types 31, 33, 45, 52, 58 and c) having no false positives were considered proficient. RESULTS In total, 84 laboratories worldwide submitted 158 datasets (some laboratories used >1 HPV testing platform). Of those, 122 (77%) were 100% proficient. Only 14/158 datasets (9%) contained false positive results. Comparison of results with assays approved by the Food and Drug Administration (FDA) suggest that future proficiency requirements should also accommodate assays detecting only 100 IU of HPV16/18. A pool of low oncogenicity HPV types that contributed very little to sensitivity, but adversely affected specificity, was detectable by most datasets. CONCLUSION Internationally recognized proficiency studies of HPV screening, traceable to international standards, provided an overview of current testing performance. There was a high level of proficiency in terms of sensitivity and few false positives, but specificity was not optimal and further research on optimal specificity of HPV screening tests may be warranted.

Abstract
Objective: To investigate the triaging efficacy of the human papillomavirus (HPV) 16/18 E7 oncoprotein assay for high-grade cervical intraepithelial neoplasia (CIN2+) screening in HPV 16/18-positive patients in a tertiary hospital in China. Methods: We collected 476 cervical cell samples from women who tested positive for HPV 16/18 in the gynecological clinic of Peking Union Medical College Hospital between September 2018 and September 2022 and analyzed them by the HPV 16/18 E7 oncoprotein assay before colposcopy and biopsy. The study assessed the triaging efficacy of the HPV 16/18 E7 oncoprotein assay in HPV 16/18-positive patients by analyzing its performance against the gold standard of histologically confirmed CIN2+. Results: The positive rate of the HPV 16/18 E7 oncoprotein assay was 41.0% (114/278) in the negative for intraepithelial lesions and malignancy/CIN1 group and 80.3% (159/198) in the CIN2+ group. For triage of women with a positive HPV 16/18 test for CIN2+ detection, the HPV 16/18 E7 oncoprotein assay had a sensitivity, specificity, positive predictive value, and negative predictive value of 80.3%, 59.4%, 58.5%, and 80.9%, respectively. Furthermore, longitudinal follow-up of five patients showed a good correlation between the expression of the HPV 16/18 E7 oncoprotein and cervical lesion grades. Conclusions: As a triage method for HPV 16/18-positive patients, the HPV 16/18 E7 oncoprotein assay improves the specificity, reduces the colposcopy referral rate, and has the potential for long-term monitoring of high-grade CIN.

Abstract
OBJECTIVE This study aimed to evaluate the feasibility of combined human papillomavirus (HPV) and optical coherence tomography (OCT) cervical cancer screening strategies. MATERIALS AND METHODS The OCT and cytology results were compared with the pathological results to calculate the sensitivity, specificity, positive predictive value, negative predictive value, and immediate cervical intraepithelial neoplasia grade 3 or worse (CIN3+) risk. The authors compared the efficiency of colposcopy by using different triage strategies. They discussed differentiation in OCT screening in different age groups. RESULTS Eight hundred thirteen participants with high-risk HPV-positive and cervical cytology results underwent OCT before colposcopy between March 1 and October 1, 2021. The HPV16/18 genotyping with OCT triage has a specificity of CIN3+ lesions (61.1%; 95% CI = 57.6%-64.6%), intraepithelial neoplasia grade 2 or worse (CIN2+) (66.0%; 95% CI = 62.4%-69.6%). The HPV16/18 genotyping with cytology triage has a specificity of CIN3+ (44.0%; 95% CI = 40.4%-47.6%), CIN2+ (47.0%; 95% CI = 43.2%-50.8%). The OCT triage has a higher positive predictive value compared with the cytology, with a significant difference in CIN2+ lesions (45.0%; 95% CI = 38.8%-51.3% vs 29.2%; 95% CI = 24.7%-33.7%). CONCLUSIONS The combination of OCT and high-risk HPV triage (both genotyping and nongenotyping) had a similar immediate CIN3+ risk stratification and reduced the number of colposcopies compared with the cytological triage strategy.

Abstract
Objective To investigate the application value of different dose of HPV vaccine in young females. Data sources The following databases were searched: Cochrane Library, PubMed, Embase, Web of Science, SINOMED, and Wanfang Data, from the establishment of the database to August 1st, 2022. Study eligibility criteria The inclusion criterias were: healthy young women younger than 25 years old as the research object, randomized controlled study as the research type, and the efficacy and safety of single-dose, two-dose or three-dose HPV vaccines as the intervention measures and research endpoints. Study appraisal and synthesis methods Meta-analysis was performed to analyze the protective effects of single-dose, 2-dose and 3-dose HPV vaccine series on young females. Results A total of eight eligible studies involving 16 publications were included. There is no difference in the immunogenicity between the 2-dose and 3-dose series within 12 months after the last dose of HPV vaccine. However, 3-dose series was better than the 2-dose series, which performed better than the single-dose vaccine, after 12 months. With respect to the prevention of HPV16/18 infection or HPV31/33/45 infection, the single-dose vaccine worked better than 2-dose or 3-dose series. Conclusions The present study showed that the immunogenicity of low-dose HPV vaccine was significantly less, but it reduced the risk of high-risk HPV infection. The low-dose HPV vaccine series may not offer a preventive effect on cervical lesions, though it needs to be further confirmed by additional studies.

Abstract
OBJECTIVE To evaluate the conization results performed due to human papillomavirus (HPV), smear, colposcopy results or clinician's decision and determine the factors that predict ≥CIN2. STUDY DESIGN Retrospective comparative study. Place and Duration of the Study: Department of Gynaecology and Obstetrics, Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital, Ankara, Turkey, between January 2011 and December 2021. METHODOLOGY Women with known HPV results who underwent conization in the Gynaecology clinic were retrospectively included. Age, HPV genotypes, conization, and colposcopy results of the patients were recorded. Patients were divided into two groups as those with and without ≥CIN2 and compared in terms of clinicopathological features. RESULTS Four hundred and twenty eight (82.8%) of the 517 patients were premenopausal and perimenopausal, and 89 (17.2%) of the patients with a median age of 42 years (range: 30-65 years) were postmenopausal. While 374 were HPV 16/18 positive, 143 were non-16/18 HPV positive. Conization result was normal in 202 (39.1%) patients, CIN1 in 129 (25.0%) patients, and CIN 2-3 in 186 (36.0%) patients. In the HPV 16/18 positive group, conization result was normal in 38.2% of patients, CIN1 in 20.9%, and CIN 2-3 in 40.9%; these rates were 41.3%, 35.7%, and 23.1% in the HPV-other group, respectively (p <0.001). In the logistic regression model, age, HPV type (16/18), and smear cytology results (≥ASC-US) were tested as independent factors predicting ≥CIN2. CONCLUSION HPV 16/18 positivity and smear cytology result (≥ASC-US) were the factors predicting ≥CIN2. Smear and HPV genotyping can make an important contribution to detecting false KEY WORDS CIN, Colposcopy, Conization, Cervix, Cervical cancer, Neoplasia, HPV.

Abstract
Vulvar squamous cell cancer (VSC) accounts for 90% of vulvar cancers. Next-generation sequencing studies of VSC imply human papillomavirus (HPV) and p53 status play separate roles in carcinogenesis and prognosis. We sought to describe the genomic landscape and analyze the immunologic profiles of VSC with respect to HPV and p53 status. A total of 443 VSC tumors underwent tumor profiling. Next-generation sequencing was performed on genomic DNA isolated from formalin-fixed paraffin-embedded tumor samples. PD-L1, microsatellite instability were tested by fragment analysis, IHC, and next-generation sequencing. Tumor mutational burden-high was defined as >10 mutations per MB. HPV 16/18 positive (HPV+) status was determined using whole exome sequencing on 105 samples. Three cohorts were identified from 105 samples with known HPV: HPV+, HPV-/p53wt, and HPV-/p53mt. Where HPV and p53 status were examined, TP53 mutations were exclusive of HPV+ tumors. In all, 37% of samples were HPV+. Among the 66 HPV- tumors, 52 (78.8%) were HPV-/p53mt and 14 (21.2%) were HPV-/p53wt. The HPV-/p53wt cohort had a higher rate of mutations in the PI3KCA gene (42.9% HPV-/p53wt vs 26.3% HPV+ vs. 5.8% HPV-/p53mt, q =0.028) and alterations in the PI3K/AkT/mTOR pathway (57.1% HPV-/p53wt vs. 34.2% HPV+ vs. 7.7% HPV-/p53mt, q =0.0386) than the other 2 cohorts. Ninety-eight VSC tumors with HPV16/18 information underwent transcriptomic analysis and immune deconvolution method. No differences were observed in immune profiles. The HPV-/p53wt VSC tumors had significantly higher rates of mutations in the PI3KCA gene and alterations in the PI3K/AkT/mTOR pathway, a potential target that merits further investigation in this subgroup.

Abstract
INTRODUCTION Persons with HIV (PWH) experience high rates of human papillomavirus (HPV)-associated cancers compared with the general population. Plasma HPV cell-free DNA (cfDNA) tests are sensitive in patients with known HPV-associated cancers. It is not known whether these tests can screen for invasive cancers in populations with high burdens of nonmalignant HPV disease such as PWH. It was not known whether HPV infection and/or noninvasive anal high-grade squamous intraepithelial lesions (HSIL) alone in this population would result in detectable HPV cfDNA, which would result in a high number of false positives if HPV cfDNA is used to screen for invasive cancers. METHODS We conducted a prospective study of PWH in 2 cohorts: 20 without anal HSIL and 20 with anal HSIL. We tested anal and vaginal swabs for HPV infection, and HPV genotyped the biopsies of anal HSIL. Finally, we performed HPV cfDNA droplet digital polymerase chain reaction to test for HPV16/18/33 from plasma samples. RESULTS In the combined cohorts, the median age was 56 years, 12.5% were cisgender women, and none had detectable HIV. In total, 84.6% had prevalent anovaginal HPV infection, including 10 participants with HPV16, 13 with HPV18, and 2 with HPV33 infections. Five and 2 participants had HPV16 and HPV33 detected in anal HSIL, respectively. Despite the high prevalence of HPV infection and anal HSIL, no participant had HPV16/18/33 detectable cfDNA by droplet digital polymerase chain reaction. CONCLUSIONS These results provide a strong rationale for investigating the use of HPV cfDNA in a screening setting for suspected HPV-related invasive cancers in PWH.

Abstract
OBJECTIVE To evaluate the effect of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) combined with CO2 laser pretreatment (Laser+ALA-PDT) on patients with cervical high-grade squamous intraepithelial lesions (HSILs). METHODS A total of 114 patients treated by ALA-PDT or Laser+ALA-PDT at 3 centers were retrospectively reviewed. The effective rate, cure rate of lesions as well as high-risk human papillomavirus (HR-HPV) regression rate and persistent infection rate in the 2 groups were compared according to 3-6 month and 9-12 months follow-ups. The characteristics and risk factors for ineffective cases were evaluated by regression analysis. RESULTS At the 3-6month follow-up, the effective rate was significantly higher in the Laser+ALA-PDT group than in the ALA-PDT group (96.6% vs. 81.3%, p = 0.048). A total of 79.3% of the laser+ALA-PDT patients achieved cure rate compared with 61.3% of the ALA-PDT patients (p = 0.082). In the Laser+ALA-PDT group, the HR-HPV-negative rate was significantly higher (72.4% vs. 50.7%, p = 0.045), while the persistence rate was significantly lower (20.7% vs. 42.7%, p = 0.037). At the 9-12month follow-up, the cure rate was 83% in the ALA-PDT group, 17% lower than that in the Laser+ALA-PDT group (p = 0.055). A total of 20.8% of patients in the ALA-PDT group and 5.3% in the Laser+ALA-PDT group showed persistent HR-HPV infection (p = 0.120). Pretreatment HR-HPV type, multiple infections and treatment modality were relevant factors for PDT outcome. CONCLUSIONS For patients with cervical HSIL, laser+ALA-PDT shows better efficiency and HPV regression compared with ALA-PDT. HPV16/18 and multi-infection may be risk factors for ineffective treatment with ALA-PDT.

Abstract
Background Infections with human papillomaviruses (HPV) are sexually transmitted and can cause cancer. In Germany, vaccination against HPV is recommended for girls and boys aged 9-17 years. We aimed to investigate HPV DNA prevalence, genotype distribution and vaccine effectiveness (VE) in women aged 20-25 years 10 years after the introduction of HPV vaccination in Germany (2018-2019), and compared these data to an equally designed study from 2010-2012. Methods Seventy six geographical clusters were randomly selected, followed by random selection of 61 women aged 20-25 years per cluster. Participants performed cervicovaginal self-sampling and answered questions on demographics, sexual behaviour and HPV vaccination. Samples were tested for 18 high risk and nine low risk HPV genotypes. We performed chi-square tests, Fisher's exact test, unpaired Student's t-test and proportion t-test, and calculated crude and adjusted prevalence ratios (PR) and 95% CIs. Results Of 7,858 contacted women a total of 1,226 agreed to participate. Of these, 94 women were positive for HPV types 16 and/or 18. HPV16 prevalence was 7.0% (95% CI 5.6-8.6) and HPV18 prevalence was 0.8% (95% CI 0.4-1.5). HPV6 and HPV11 were rare with only five (0.4%; 0.1-0.9) and one (0%; 95% CI 0.0-0.5) positive tests. Seven hundred fifty-seven women (62%) had received at least one HPV vaccine dose and 348 (28%) were vaccinated as currently recommended. Confounder-adjusted VE was 46.4% (95% CI 4.2-70.1) against HPV16/18 infection and 49.1% (95% CI 8.2-71.8) against infection with at least one HPV genotype covered by the quadrivalent HPV vaccine. Compared with the 2010-2012 study results, HPV16/18 prevalence dropped from 22.5% (95% CI 19.0-26.3) to 10.3% (95% CI 7.5-13.9; p < 0.0001) in unvaccinated participants. Conclusion Vaccine-covered HPV genotypes were rare among 20-25 years old women in Germany and decreased compared to the time point shortly after the start of the HPV vaccination program. HPV prevalence of almost all vaccine-covered genotypes was strongly reduced in vaccinated participants. A decrease of HPV16 and HPV18 was even observed in unvaccinated participants, compared to 2010-2012 data, suggesting indirect protection of unvaccinated women. Low VE against HPV16/18 and HPV6/11/16/18 in our study might be attributable to study design in combination with the endpoint selection of (mainly transient) HPV DNA positivity.
