Active clinical trials for "Uterine Cervical Dysplasia"

The purpose of this study is to determine the possibility and compliance of performing anal Pap smear and Human Papilloma Virus (HPV) DNA testing on women with high grade lower genital tract dysplasia or cervical cancer and determining the prevalence of anal dysplasia in this population using a high-resolution anoscopy (HRA). In addition, it is being done to potentially develop screening, diagnostic and treatment protocol for anal dysplasia in women with high-grade lower genital tract dysplasia or cervical cancer.

This study is a clinical study aiming at establishing immunological assays for the qualitative and quantitative evaluation of WT-1, Survivin and HPV16 E7-specific immune responses in cancer patients. Such a study will allow the development of suitable immunological tools to be used in assessing response in a subsequent phase I study aiming at evaluating therapeutic vaccine candidates targeting WT-1, Survivin and/or HPV16 E7-expressing tumors. In addition, this study will help defining the baseline cancer-associated immune responses in the selected patient population. Cervical and ovarian cancer patients, as well as leukemia patients, will be included in this study. WT-1, Survivin and HPV-specific immune responses will be monitored in these patients by ex vivo and cultured IFNg ELISpot as well as tetramer staining.

This study will pilot production and evaluate the use of reminder information in women invited for cervical screening for the first time within the GGC eligible population for cervical screening. Women aged under 30 years will be identified to receive an SMS text message following their cervical screening invitation using information from the CHI Broadcast.

This study intends to carry out a prospective, randomized controlled trial to research and development a new invivo microscopy based on the technology which is combined with high-definition microscopy and colposcopy，so as to diagnose cervical lesion directly and non-invasively by observing cervical tissues and cells, which makes it possible to diagnose cervical cancer without wounds.

The European VALHUDES study is a Clinical Performance /Diagnostic Test Accuracy Study that aims to evaluate whether HPV testing with new assays performed on self-samples, collected by means of a vaginal and a urine collection device is as accurate to detect cervical pre-cancer as on cliniciantaken cervical samples.

Cervical conization using the loop electrosurgical excision procedure (LEEP) is the standard treatment for patients with high-grade cervical intraepithelial neoplasia. Several studies have shown that excising a central cone reduces the rate of positive endocervical margins. The purpose of this study is to identify clinicopathological factors associated with residual disease in the central cone and to develop a predictive model to better determine which patients may require this additional procedure.

Objectives: To identify factors associated with disease recurrence in patients with high-grade cervical intra-epithelial neoplasia (CIN) undergoing large loop excision of the transformation zone (LLETZ). Study Design: A case-control study that included 103 patients. Patients were included in the study if they had a history of surgery for conization by LLETZ for the histopathological diagnosis of cervical intraepithelial neoplasia grades II and III (CIN II and CIN III). Follow-up exams were conducted every six months with Pap smear collection and colposcopic examination with biopsy, when necessary, for a minimum period of twelve months. Cure was defined as a normal follow-up examination within 24 months. During follow-up, relapse occurred when cytology and/or biopsy results showed that CIN had returned after 12 months, at which time a new cervical conization by LLETZ was performed.

Cervical cancer is the third most frequent neoplasm in Brazilian women (estimated risk of 15.33 cases / 100,000 women by 2014), behind breast and colorectal cancer. This high incidence is explained by the pre-neoplastic lesions of the cervix being probably related to the practice of unsafe sex and to a poor local immune response against HPV. Human papillomavirus (HPV) infection affects people of any age, although it is more common in young people, probably due to increased sexual activity in that period. The association between high-risk HPV and anus neoplasm in men and women with immunodeficiency or immunosuppression has been confirmed and measures related to surveillance are standardized. In patients without immunodeficiencies, this association is still unclear, which may contribute to the lack of adequate standards to diagnose HPV and prevent cancer of the anus. The frequency of the cancer of anus previously considered low, is currently in considerable elevation, mainly squamous cell carcinoma (SCC). The causal relationship between this virus and cancer of the cervix and the anus is established. These facts have motivated the inclusion of this disease as STD, which justifies the necessity of adopting surveillance measures in the clinics of sexual, gynecological and urological diseases. Cancer of the anus, when diagnosed in the early stage, makes healing possible with less aggressive treatments, but in the advanced stage, abdominoperineal amputation is necessary. Concerned about possible anal cancer, some gynecologists have referred patients with genital HPV to search for anal infection.

This is a prospective study to compare unpolarized (conventional) to polarized light colposcopy. Subjects will be asked to participate in the study when they arrive for their prescheduled colposcopic examination. The study doctor will use a conventional or standard colposcope to perform the examination. His/her impression of the exam will be noted and if necessary a biopsy specimen will be obtained. The study doctor will then perform a colposcopy using a polarized light. His/her impression of the exam will be noted and a biopsy specimen will be obtained if necessary. This study is designed to test the hypothesis that polarized light colposcopy is more sensitive and more specific than standard, un-polarized light colposcopy.
