Active clinical trials for "Uterine Cervical Dysplasia"

This study is to follow up on the change of immune response by measuring HPV type 16/18 E6 and E7 specific T cell response and lesion condition in subjects who have administered in DNA-based therapeutic vaccine.

The aim of this study is to retrospectively evaluate the effectiveness and safety of Er:YAG laser for treatment of different gynecological indication, e.g. genital lesions, Bartholin's cyst, condyloma, episiotomy scars, lesions of hydradenitis suppurativa and use of laser in genital surgery used in private practice.

Human papilloma virus (HPV) infection contributes as a main causative factor to the development of invasive cervical cancer (ICC) and its precursors (cervical intraepithelial neoplasia, CIN). Currently, two prophylactic vaccines are employed for the prevention of genital HPV infection. As the prophylactic efficacy is type-restricted, determining the type-specific HPV distribution and their associations with ICC and its precursors would provide essential information in assessment of HPV vaccination program impact. The baseline information is also important for monitoring possible changes in type-specific HPV distribution after vaccination has been introduced. Prevalence of HPV infection varies considerably across the world, and data were limited from less-developed countries. Knowledge of the detail pattern of HPV type-specific distribution in each region will be essential for public health policy decisions. This will also form the basis for determining which types should be included in future generation HPV vaccines targeted to specific regions. While most studies were focus on ICC and high-grade cervical lesions, the association between HPV types and the progression of CIN1 has rarely been studied. CIN1 is an insensitive histopathological sign of HPV infection, most of which will spontaneously regress to normal with host immune system. However, some genotypes have been described as being more persistent and associated with progression from low-grade lesions to high-grade lesions, even ICC. Geographical data on type-specific prevalence of HPV in CIN1 with appropriately designed prospective studies would be helpful in identifying types preferentially associated with progression to malignancy and accurately predicting the future impact of vaccination in specific regions. Free vaccination supported by the government appears to be unlikely at present in China. Thus, individuals need to pay the cost of vaccines for themselves presently. Yangtze River Delta Area is the most economically developed regions in China, and people here may become the largest vaccinated population at their own expense in China. To the best of the investigators knowledge, no multi-center study on HPV type-specific distribution and their associations with ICC and its precursors is available in Yangtze River Delta Area, China, which highlights the need for timely study in this region before large scale vaccination programs are carried out.

The purpose of this prospective study is to evaluate whether DNA methylation can be applied in cervical cancer screening.

The primary objective is to determine the sensitivity and specificity of the HPV Integration-based cervical screening for detection of high-grade cervical intraepithelial neoplasia (CIN), using colposcopic inspection as the reference method. Lesions will be confirmed as malignant or CIN by colposcopic inspection and histopathologic examination.

The multimodal imaging technology, OCT-AFI, will be used to image sites on the cervix, the endocervical canal and vulva. The imaging probe is small enough, it can be inserted into the endocervical canal for imaging. The probe can also be placed in a conformable holder that can be shaped to conform the the folds of the vulva for vulvar imaging. The resultant images will be compared to histology images. The objectives are to determine feasibility of the technology in imaging vulva and its capability in detecting vulvar intraepithelial neoplasias feasibility in imaging cervix from endocervical canal to transformation zone to ectocervix if combined OCT with AFI increases the sensitivity of detecting high grade lesions in the cervix compared to just AFI alone (previous work was AFI alone).

This study evaluates the Dynamic Spectral Imaging (DSI) Colposcope (DySIS) in it's ability to diagnose cervical dysplasia. Half of participants with be examined by the DySIS colposcope, there the other half will be examined by standard colposcopy.

Papanicolaou (Pap) triage, with high specificity, has been recommended for primary Human papillomavirus (HPV) testing but is flawed by poor sensitivity and cytologist dependence. the investigators evaluated the potential role of HPV Integration detection in cervical exfoliated cells in HPV-positive women from a clinic-based population.

The "Extended VALHUDES" study is a Clinical Performance / Diagnostic Test Accuracy Study that aims to extend validation, achieved as part of the "Belgian VALHUDES", of HPV testing using BD Onclarity on samples collected using Copan's devices for dry self-sampling of vaginal material and for first-void urine: FLOQSwab® 5E089N and UriSponge™.

The purpose of this study is to determine whether Insulin-like Growth Factor II is elevated sufficiently to detect Cervical Intraepithelial Neoplasia II (CIN II), Cervical Intraepithelial Neoplasia III (CIN III), and cervical cancer.
