NCT07059819
Human papillomavirus(HPV) infect epithelial cells and have the capacity to stimulate cell abnormal hyperplasia, especially by those high-risk HPV types. HPV vaccine primarily targeting HPV6/11/16/18 has been available and makes it possible to prevent cervical cancer. However, a large population was left unvaccinated, specifically for those aged ones. In clinic, patients harboring high-risk HPV is quite prevalent in China or other developing nations. Removing the virus and prevention of malignant transformation is required. Mild local Hyperthermia with a certain temperature range has been successfully used in the treatment of some diseases. It has been utilized in the treatment of some neoplasm, fungal and HPV infections. Investigators' study found that local hyperthermia at 44°C could cleared HPV in more than half of the patients with HR-HPV in cervical area. So the purpose of the study is to evaluate the effective of local hyperthermia in the treatment of cervical intraepithelial neoplasias grade I and II after 3 months. Appropriate control arms were designed for different conditions.
NCT05266898
The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objectives of the study are to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series, and to determine the protection afforded by Gardasil vaccine over time in previously vaccinated adults living with HIV. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes and continuing protection against vaccine genotypes of HPV over time.
NCT06823817
Colposcopy has become an important link and tool in the prevention and treatment of cervical cancer. The quality and pathological assessment of colposcopy is a key point in follow-up and treatment.The main purpose of this study was to analyze the correlation between colposcopy indications and pathological findings.
NCT02328872
Compass is a randomised controlled trial of primary HPV testing for cervical cancer screening in Australia. A pilot study involving 5,000 women was carried out in 2013-2014. The trial will involve recruiting 76,300 women from primary health clinics. Women aged 25-69, attending for cervical screening or for routine follow-up will be invited to participate in the 2-arm trial. A liquid-based cytology (LBC) sample will be taken from consenting women and sent to VCS Pathology. Women will be randomised in a 1:2 parallel group allocation to LBC and HPV arms using randomisation with the minimisation procedure, with stratification by birth cohort according to whether offered HPV vaccination in Australia's national publicly-funded HPV vaccination program (date of birth \>=July 1st 1980 and \<1st July 1980). In the LBC (active control) arm, women will undergo 2.5 yearly image read cytology screening with reflex HPV triage testing for low grade cytology. In the HPV (intervention) arm women will undergo 5 yearly HPV screening with partial genotyping enabling separate identification of HPV16 and HPV18 and referral of this group for diagnostic evaluation, and secondary randomisation of "intermediate risk" women testing positive for oncogenic HPV (but not HPV 16 or 18) to either image read LBC screening or dual-stained (DS) cytology testing with p16/Ki67. The laboratory reports issued to practitioners will specify the recommended management for women, according to study arm and test results.Participating women will be flagged and clinical outcomes will be tracked via the Compass Register. Data linkage between the Compass Register and HPV vaccination records held on the Australian Immunisation Register will be performed in order to integrate vaccination and screening histories for trial participants. Participants will be actively followed for an anticipated 5 years from the time of recruitment and the primary outcome is based on the total cumulative detection of CIN3+ after exit testing at 5 years. The anticipated study completion date of March 2027 takes into consideration the final migration of participants to the National Cancer Screening Register and allows for two years to follow-up any intermediate risk results occurring in the last of the recruited trial participants.
NCT02149030
The main objective of the study is to identify whether or not being informed infrequently results about screening is: 1) At least as safe and accurate as frequently obtaining all information from the present combination of opportunistic/organized cervical screening by comparing regimen results of three screening visits at the ages of 22, 25 and 30 years (Arm A1) vs. results of one screening visit at the age of 30 years (Arm A2) in Human papillomavirus (HPV) vaccinated young women.
NCT06700941
The goal of this observational study is to assess the impact of HPV vaccination on cervical lesions and genital warts in Colombian birth cohorts. The study examines the trends in healthcare services usage related to these conditions, particularly among vaccinated and unvaccinated populations. The main questions it aims to answer are: Have health services usage rates for preneoplastic cervical lesions and genital warts decreased among cohorts of girls eligible for HPV vaccination after the vaccine's introduction? Have there been reductions in health services usage for genital warts among male cohorts of the same birth years as vaccinated girls? Researchers will compare health services usage trends between vaccinated and unvaccinated populations, as well as geographical areas with differing levels of HPV vaccination coverage, to evaluate the impact of the HPV vaccination program. Participants will not be directly involved, as this is a retrospective analysis of existing healthcare records from various national databases, assessing the frequency of healthcare services related to preneoplastic lesions and genital warts, as well as vaccination coverage at national, departmental, and municipal levels.
NCT06665841
This study investigates the relationship between selenium levels in human tissues and the persistence of HPV (human papillomavirus) infection, particularly focusing on cervical-related lesions. The main objectives are to explore the correlation between selenium levels in different body samples (hair, nails, urine, and blood) and to evaluate selenium's potential protective effects against HPV persistence and its progression to cervical lesions. Key goals of the study include: Determining whether non-invasive monitoring (e.g., hair, nails, urine) can accurately reflect blood selenium levels. Understanding how selenium levels fluctuate in women with persistent HPV infection, and whether selenium supplementation can reduce the risk of HPV-related cervical disease progression. Exploring selenium's role in enhancing immune function, especially in older adults, to help clear HPV infection. By recruiting volunteers for selenium level testing and tracking HPV-positive women over time, this research aims to provide evidence on the effectiveness of selenium in preventing cervical cancer progression and potentially clearing HPV infections.
NCT06557954
Cervical cancer represents one of the foremost causes of cancer-related morbidity and mortality among women worldwide. Given the current limitations, such as the low specificity of human papillomavirus (HPV) testing and the relatively low sensitivity of cytological examinations, there is a pressing need for a novel, non-invasive, safe, and precise screening method. This study aims to undertake a multicentre, real-world investigation, incorporating at least 10 sub-centres and enrolling 30,000 participants. Histopathological examination results will serve as the 'gold standard' for evaluating the screening efficacy of human PAX1 and JAM3 gene methylation assays (PAX1m/JAM3m), HPV testing, and cytological examinations. Furthermore, the study seeks to elucidate the relationship between DNA methylation levels and persistent HPV infection, while also assessing the applicability of PAX1m/JAM3m across diverse clinical settings. By focusing on alterations in DNA methylation levels within cervical exfoliated cells as the primary research trajectory, this study aspires to furnish novel insights and theoretical foundations for the prevention and management of cervical cancer, targeting PAX1m/JAM3m. The ultimate objective is to facilitate the clinical implementation of an enhanced cervical cancer screening protocol, thereby addressing the deficiencies of current screening methodologies, achieving greater precision in cervical cancer screening, and effectively reducing the incidence of cervical cancer while mitigating the risks of overdiagnosis and overtreatment.
NCT03218436
Cervical intraepithelial neoplasia will be treated with physical low temperature plasma in the plasma cohort compared to watchful waiting in the control cohort. Primary endpoint after 3-6 months: Pathological remission. Secondary endpoint: HPV remission.
NCT01511328
The purpose is to evaluate whether implementation of primary human papillomavirus (HPV) screening in the screening programme for cervical cancer improves the programme in terms of better cancer protection and better cost efficiency.
NCT05851079
The goal of this observational study is to compare the accuracy and sensitivity of High-throughput human papilloma virus(HPV) typing and integrated assays with routine screening protocols (Cobas HPV test combined with thinprep cytologic test(TCT) for the detection of cervical intraepithelial neoplasia in the general and hospital populations. The main questions it aims to answer are: * High-throughput HPV typing and integrated assays can screen for ≥ cervical intraepithelial neoplasia (CIN2 or CIN3) with high sensitivity and accuracy. * High-throughput HPV typing and integrated assays can be promoted as a screening tool for cervical cancer. Participants will be screened with routine screening protocols (Cobas HPV test combined with TCT test), and if the results are abnormal, colposcopy and cervical biopsy will be performed.

The primary objective of this study is to evaluate the immuno-persistence (type specific IgG antibody) of the tested vaccine administered in girls aged 9-17 years,comparing to young healthy adults of 18-26 years who received the standard 3-dose schedule (0,1,6 months).
NCT02733068
A Phase III Double Blinded, Randomized Controlled Study to Evaluate Efficacy of Protection Against HPV-16 and 18 Related Diseases, Immunogenicity and Safety of Recombinant Human Papillomavirus Virus-like Particle Vaccine (Type 16 and 18 L1 Proteins, Yeast) in Healthy Females Aged 18-30 Years.
NCT05142397
Cervical cancer is the fourth leading cause of cancer death in women worldwide, and cervical intraepithelial neoplasia (CIN) can progress to cervical cancer. Therefore, timely treatment of CIN is critical in preventing the occurrence of cervical cancer. With the implementation and promotion of the World Health Organization's 2030 Global Strategy for the Elimination of Cervical Cancer, an increasing number of women are detecting and treating CIN at an earlier stage. Common treatment methods include ablation treatment and excision treatment, but for women who are planning to have children, the risk of cervical insufficiency and pregnancy complications is greatly increased after excisional treatment, so ablation treatment seems to be a better choice.
NCT05290428
Based on the previous study of NCT03961191 and NCT03960879, we performed this trial to further confirm the accuracy of host DNA PAX1 and JAM3 methylation for cervical cancer screening. This study would provide profound basis for the approval of assay kit of DNA methylation in China for cervical screening. Three hospitals, including Peking Union Medical College Hospital, would enroll eligible patients in this study. The cervical cytology of 3 ml will be collected for the detection of DNA PAX1 and JAM3 methylation, and the results will compared with the cervical histological pathology, which is achieved after collection of cervical cytology, by surgeries including loop electrosurgical excision procedure, cervical conization, total hysterectomy and others. The methylation testing would be double-blinded in operators and analysts. The retrospective and prospective parts will enroll at least 120 patients and at least 339 patients, respectively.
NCT02354534
This phase I research protocol is designed to assess immunogenicity and clinical endpoints in patients with human papillomavirus (HPV) 16 cervical intraepithelial neoplasia (CIN)2/3. The protocol tests the use of artesunate in suppository formulation applied intravaginally in patients with cervical dysplasia (CIN2/3). The primary endpoint is to determine and evaluate the safety, tolerability, and feasibility of intravaginal administration of artesunate in health women with CIN2/3.
NCT04783805
Conservative management of high-grade squamous intraepithelial lesions (HSILs) seems safe and justified in young women (\<30 years), but evidence is insufficient on whether it is also advisable for older women. This study will be conducted to analyze spontaneous HSIL regression rates in women of reproductive age and establish whether conservative HSIL management could be safely recommended to women of childbearing potential, irrespective of age. This is a single-center prospective observational study that will include consecutive women of reproductive age, referred to a tertiary hospital due to HSIL between March 2021 and December 2025, who prefer conservative management rather than immediate cervical conization. All patients will be followed-up regularly with colposcopy, cytology, human papillomavirus (HPV) testing and biopsies. In case their lesions progress or HSIL persists after 24 months of follow-up, conization will be indicated. Rates of spontaneous regression or resolution, as well as progression rates, will be assessed. Furthermore, the association between potential predictive factors and HSIL resolution will be analyzed.
NCT03355820
The purpose of this study is to evaluate the persistence of immune response in subjects who received the HPV-16/18 vaccine, seven to eight years after the last dose of primary vaccination in the HPV-058 study. No new subjects will be enrolled in this extension study.
