Filter by: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.
This trial will evaluate the possible benefits and the performance of liquid biopsies in HPV-associated cancer treatment monitoring. This study aims to find a combination of an adequately sensitive and specific sampling method and biomarkers for early risk stratification of disease recurrence.
High-risk precancerous cervical lesions are divided into stage 2 and 3 cervical intraepithelial neoplasia (CIN 2 and 3). CIN 3 represents a direct pre-stage of invasive cancer, has a high rate of progression and a high degree of agreement with the final histological diagnosis. In CIN 2 lesions, the rate of agreement with the final histological diagnosis is lower and the rate of spontaneous regression is higher. Due to the higher rate of regression and possible complications after excisional treatment, conservative active monitoring can be considered in selected young CIN 2 patients. A recent meta-analysis reported a high rate of spontaneous clinical regression of CIN 2, particularly in women under 30 years old. There are currently no prospectively validated prognostic biomarkers to determine which CIN 2 will progress to higher grade and which will regress to lower grade of change. Recent research has studied HPV methylation and microbiome analysis as biomarkers. A number of studies have shown that host cell DNA methylation levels in cervical scrapes increase with underlying cervical disease severity and are highest in cervical cancer. DNA methylation involves the covalent binding of a methyl group to the 5´ position of a cytosine molecule in CpG dinucleotides. Besides global hypomethylation, the overall loss of methylation during carcinogenesis, resulting in chromosomal instability, and the silencing of tumour suppressor genes by local hypermethylation of CpG-rich promoter regions contribute to cancer development. Gene promoter methylation can be easily accessed by sensitive, quantitative methylation-specific PCR providing an objective test outcome. The aim of this study was to determine the effect of the methylation rate of two suppressor genes- FAM19A4 and hsa-mir-124 on the rate of CIN 2 regression, persistence or progression in women younger than 36 years (≤35 years old).
Cervical cancer seriously threatens women's health and HPV infection is the main cause of cervical cancer. Traditionally, Cervical cancer screening is based on cervical exfoliated cell samples collected by health care provider, which is labor consuming and the coverage and compliance are both relatively low in some areas. Non-invasive hrHPV self-sampling test appears to be more acceptable and may improve the HPV screening coverage. This study aims to evaluate the clinical performance of a newly developed urine/vaginal self-sampling hrHPV test in Cervical cancer screening.
In France, the screening rate for cervical cancer remains too low. Screening is simple and non-invasive. Pregnant patients are most of the time young and are part of the target population for screening, and for many women, it is the first encounter with a gynecologist. The cervical smear is therefore an important step of the first consultation during pregnancy In the case of pathological results, colposcopies with biopsies are performed, frequently finding CIN 1 to 3. (cervical intraepithelial neoplasia) These CIN lesions evolve slowly and most of the time, treatment can be withheld until the end of the pregnancy. Several studies suggest a higher regression rate in pregnant patients. Our study will evaluate the rate of regression, progression or persistence of these lesions in per and post partum patients in Nancy, between 2014 and 2022. To obtain our results, we will compare the results of per and post partum biopsies in each patient. In a second step, we will study the risk factors of aggravation or on the contrary the protective factors, allowing a faster regression of the lesions
Uterine cervical dysplasia and other female genital dysplasia continue to be significant health problems despite Cervical Screening Programs and HPV vaccinations being available. These female genital dysplasia [FGD] induced by HPV infections affect disadvantaged women in the US and globally more than others: minorities like African Americans [AA], rural populations, lower socioeconomic strata of the society and less educated in the US and lower / middle income countries. The reasons are: lack of access to screening and vaccines, lack of infrastructure, fear and shame of getting a pelvic examination and pap's smear and inability to go to the health centers that provide these cares. A simple blood test that can diagnose FGD can help make many of those hurdles go away. This proposal is to utilize the emergence of 'liquid biopsy' concepts using genomic/precision medicine advances of the past decade to have such a blood test to be made available. Collaborating with Naveris, Inc,® the clinical study will use their NavDx® blood test. This is a test for circulating cell-free tumor tissue modified viral (TTMV®)-HPV DNA. TTMV-HPV DNA is a clinically proven and analytically validated highly sensitive and specific biomarker for the identification of post-treatment recurrent and residual Human Papillomavirus (HPV)-driven squamous cell oropharyngeal carcinoma (OPSCC)1,2. Data is accruing for other major HPV-driven cancers including anal cancer and uterine cervical cancer with clinical utility appear similarly promising3. TTMV-HPV DNA is a distinct biomarker for HPV-driven malignancy and can distinguish between HPV-driven malignancy and acute and or chronic HPV infection. In this study, taking advantage of a robust Cervical Dysplasia Clinic in existence at UMMC and a team of multidisciplinary experts focused on this project, the blood levels of TTMV-HPV DNA will be determined through a fully informed IRB approved clinical trial process to correlate with the grades of dysplasia, any increasing values correlating with worsening grade/malignant transformation and other variables. This pilot study is the first of this type of biomarker-based 'screening' study, and if successful, will lead to a more efficient and convenient way to diagnose HPV-induced that will be cost effective and will need minimal infrastructure. Such a test will make remarkable beneficial differences in early diagnosis, early screening compliance, early interventions as well as improving outcomes in FGD patients worldwide. With the available infrastructure and expert team, this project can be successfully completed in a relatively short time.
For the patients with cervical persistent infection or integration of HPV, we has designed a program to perform cervical conization for certain patients to earlier and better diagnose and cure the diseases of HPV infection and related cervical intraepithelial neoplasia/cancer.
This is an open-label study to evaluate the safety, tolerability, and efficacy of ABI-2280 in participants with cervical squamous intraepithelial lesions. This study is divided into 2 parts - Part A and Part B. Part A consists of 3 dose escalating cohorts. Part B is a dose expansion cohort. Participants will self-administer ABI-2280.
