Active clinical trials for "Uterine Cervical Neoplasms"

This study aims to determine survival outcomes (overall survival and progression-free survival) of primary malignancies of uterine cervix in China and relevant risk factors in a prospective cohort study.

Background: The Apparent Diffusion Coefficient (ADC) acquired by Diffusion Weighted Imaging (DWI-MR) has been shown to correlate with cellular density. The ADC is indicative of Gross Tumour Volume (GTV), and preliminary data shows that the dynamics of DWI volumes during treatment (shrinkage) as well as dose to DWI volumes has impact on treatment outcome. Hypoxic tumour cells within the primary tumour have been identified to have prognostic importance for local control Tumour hypoxia is caused by insufficiency of the tumour vasculature leading to both chronic diffusion limited and acute flow limited hypoxia. Radioresistant hypoxic cells diminish the rate of local control, and the hypoxia driven increase in metastatic potential of the tumour and lowers the rate of distant disease control. Functional imaging has the potential to visualise radioresistant tumour subvolumes. PET scanning (18F-FAZA) is hypothesized to visualise hypoxic tumour subvolumes, and dynamic contrast enhanced (DCE) MR imaging has been used to quantify the extent of poor perfusion regions within cervical tumours. Objectives: Primary: Sensitivity and specificity of functional imaging (18F-FAZA PET (optional), T1w, T2w, DWI-MRI and DCE-MRI) to identify tumours with good and bad response to radio-chemotherapy Secondary: Determining whether there are differences in bias between centre. The difference in bias will be assessed for the T1 and T2 scans and the Ktrans and ADC maps.

The investigators have planned this project to evaluate the follow-up program after surgery due to cervical cancer and to explore the possibilities for different tests of Human Papilloma Virus (HPV) in contributing to the customization of the follow-up program. Purpose: The investigators effort is to provide the background for an evidence-based update of the follow-up program after surgery due to cervical cancer with the purpose of early diagnosis of recurrence affecting quality of life for as few women as possible.

Human papillomavirus (HPV) of high-risk genotype is a necessary risk factor in development of cervical cancer. There is a vaccine available to prevent cervical lesions associated with high-risk HPV genotypes 16 and 18. In Croatia HPV vaccination has not yet been introduced in obligatory vaccination schedule. The aim of this study is to describe the pre-vaccination distribution of HPV genotypes in women with high grade cervical squamous intraepithelial lesion (HSIL) and cervical cancer in Croatia. The investigators hypothesis is that HPV-16 is the most frequently found genotype but the distribution of other HPV genotypes is heterogeneous and includes genotypes currently not covered by vaccination.

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.

The primary objective of this study is to compare the testing of DNA methylation, high-risk HPV subtypes, and cytology with the definite histological results in a case-control study, so as to determine the accuracy of DNA methylation in the screening of uterine cervical lesions. This study will include 300 patients with definite histological results, with 100 of cervical inflammation or low grade squamous intraepithelial lesions (LSIL), 100 of high grade squamous intraepithelial lesions (HSIL), and 100 of uterine cervical cancer. All the cervical specimens of cytology collected in the clinical settings will be utilized for the testing of DNA methylation, high-risk HPV subtypes and thin prep liquid-based cytology test (TCT). The sensitivity, specificity, positive predictive value and negative predictive value were calculated based on the known histological results. The differences of DNA methylation with high-risk human papillomavirus (HPV) and TCT will also be analyzed. The testing of DNA methylation will be performed with the methylation-specific polymerase chain reaction (PCR). The TCT and HPV testing will be performed with the Roche kits.

Little is known about the characteristics of genetic mutation in recurrent cervical cancer. This study is to explore the targeted genetic mutations via a multi-gene panel, which consists of more than 500 hundred genes. The mutation characteristics are to be revealed in single nucleotide variants, copy number variations, insertion-deletion variations, and genomic structural variations. The total mutation burden (TMB) will be calculated. The status of microsatellite instability, expression of PD-1 and PD-L1 antibodies are also tested. These findings will be studies in association with the patients' prognosis and sensitivity to platinum-based chemotherapy and immunotherapy.

The associations between female inflammatory bowel disease (IBD) patients and human papilloma virus (HPV) infection and cervical neoplasia (dysplasia or cancer) were unclear. Especially there was no data for Chinese IBD population. So we investigated the incidence and risk factors of HPV infection and cervical neoplasia (dysplasia or cancer) in female IBD patient.

In the United States, the highest incidence of cervical cancer occurs in inner city urban centers, rural areas, the deep South, Appalachia and the U.S.-Mexico border. The goal of this study is to study predictors of adherence among patients seeking care at an inner city medical center in New York City and the U.S. Mexico border for cervical cancer prevention, namely, Pap smears and colposcopy exams.

To conduct a quantitative survey to measure knowledge about Human papillomavirus (HPV) and cervical cancer, and HPV vaccine acceptability among parents of rural adolescent girls in Mysore District, India. Hypothesis: General knowledge and attitudes about the severity and treat ability of cancer will predict acceptability of HPV vaccination among parents of rural adolescent girls in Mysore, India.
