Filter by:Longitudinal study in Burundi to evaluate the effectiveness, the acceptability and safety of thermal ablation in the treatment of cervical neoplasia.
The prevalence of cervical neoplasia in Cambodia is not known. There are no screening programs in place. The investigators plan on introducing a screening program based on WHO criteria and utilizing visualization with acetic acid. Patients who are positive will be offered same-day cryotherapy if indicated or will be referred for biopsy, LEEP and hysterectomy as indicated. The planned patient pool for this study is 1000 women, half of whom will be HIV positive (and thus have a presumed higher incidence of cervical neoplasia).
Background: - National Cancer Institute Protocol 04-C-N191, also known as the Costa Rica Vaccine Trial, was a double-blind controlled study of the effectiveness of an experimental human papillomavirus (HPV) vaccine in preventing cervical cancer in young women in Costa Rica. Costa Rica was part of the first large study to show the association between HPV and cervical cancer, and the study contributed greatly to the understanding of this association. The women who have participated in the vaccine trial in Costa Rica are reaching the end of the follow-up period offered in the vaccine trial protocol, and as a result they are being offered the chance to have complementary vaccinations against HPV, hepatitis A, and hepatitis B. Objectives: - To offer participants in the Costa Rica Vaccine Trial the vaccine that they did not receive during the masked portion of the trial (HPV vaccine or hepatitis A vaccine) and hepatitis B vaccination. - To collect information about exposure to known and suspected risk factors for HPV infection and cervical cancer from women who are receiving vaccination against HPV at crossover. Eligibility: - Women who participated in National Cancer Institute Protocol 04-C-N191. Design: - All participants will be offered vaccination against hepatitis B. - Women who received the hepatitis A vaccine during the trial will be offered vaccination against HPV. - Women who received the HPV vaccine during the trial will be offered vaccination against hepatitis A. - Appropriate vaccinations (including a combined hepatitis A and hepatitis B vaccine) will be available to reduce the number of injections that participants will be asked to receive. - All vaccines will be given according to the manufacturer's specifications for appropriate length of time between vaccine doses.
The overall objective of this study is to evaluate whether fluorescence and reflectance spectroscopy can improve the ability to detect the presence of premalignant lesions on the cervix. The specific aims of the study are: - To compare information obtained from fluorescence and reflectance spectroscopic measurements of the cervix with standard methods for detecting cervical pre-cancers. - To validate previously developed algorithms for discriminating between normal and pre-cancerous tissue based on spectroscopic measurements. - To evaluate the safety of spectroscopic measurement of cervical tissue.
The aim of this study is to see whether a new self-sampling device, the Delphi Screener (Delphi Devices, Scherpenzeel, Netherlands), can be used for cervical cancer screening. The results using the new device will be compared to results using the current gold standard. The gold standard is clinician-collected endo-cervical and ecto-cervical specimens (often referred to as a 'Pap smear'). Additionally, women will be asked about the acceptability of using the device and how easy it is to understand the user instructions. The Delphi Screener is a sterile, plastic, syringe-like device containing buffered saline which allows a woman to collect her own vaginal lavage (to 'self-squirt'). The hypothesis is that the device may work well for cervical cytology and will be acceptable to the women in the study.
Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. Indeed, certain oncogenic types of HPV can infect the cervix (part of the uterus or womb). This infection may go away by itself, but if it does not go away (this is called persistent infection), it can lead in women over a long period of time to cancer of the cervix. This study will supplement an ongoing study evaluating the safety, efficacy and immunogenicity of the vaccine in women aged 26 years and above. This study will therefore assess additional immunogenicity parameters of the vaccine in women from selected investigative sites. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
Background: - In most women, HPV infection does not cause symptoms and the infection goes away on its own. In a small percentage of women, the HPV infection does not go away and sometimes can result in cervical precancer or cancer. - There are several different types of HPV. A better understanding of which types are related to cervical precancer and cancer may help guide doctors in clinical management of women who test positive for HPV and better understand why some women develop disease while others do not. Objectives: - To determine whether certain types of HPV are more risky than others and if so, whether they warrant separate detection in screening for cervical precancer and cancer. - To determine if lasting infection by different HPV types carry different risk of cervical precancer and cancer. - To determine what viral and genetic factors influence the development of cervical precancer and cancer. - To evaluate new HPV tests and new biomarkers of cervical cancer risk. Eligibility: -Women 30 years of age and older who are in the cervical cancer screening program at the Kaiser Permanente health plan in Northern California. Women who tested positive for HPV and a random sample of women who tested negative for the virus are included. Design: -Data about participants genetic background and the type of carcinogenic HPV with which they are infected are analyzed.
