Active clinical trials for "Uterine Cervical Dysplasia"

Human papillomavirus (HPV)-based cervical screening is known to increase sensitivity for detection of high-grade cervical intraepithelial neoplasia (CIN). Randomized trials of longitudinal efficacy are required to assess whether these gains represent overdiagnosis or a protective effect. Methods: A total of 12527 women, aged 32-38, attending population-based invitational screening in Sweden were randomized 1:1 to HPV test and cytology (intervention arm) or cytology only (control arm). HPV-positive women were invited for a second HPV test at least one year later and women with type-specific persistent infections were then invited to colposcopy. A similar number of random double-blinded procedures are performed in the control arm. Women are followed with comprehensive registry-based follow-up. Primary outcome is the relative rates of CIN grade 2 or worse (CIN2/CIN3+) found in subsequent screening. Secondary outcomes are the relative rates of CIN2/CIN3+ found in the aseline screening and outcomes stratified by grade of CIN (CIN 2 or CIN3+).

This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.

RATIONALE: Vaccines made from protein and DNA may help the body build an effective immune response to kill abnormal cells in the cervix. The use of vaccine therapy may prevent cervical cancer. PURPOSE: This phase I/II trial is studying the side effects and best dose of vaccine therapy and to see how well it works in preventing cervical cancer in patients with cervical intraepithelial neoplasia and human papillomavirus.

To determine the efficacy and safety of intravaginal fluorouracil administered as prophylaxis in HIV-infected women who have received standard ablative therapy (surgery) for high-grade cervical dysplasia (pre-cancer of the cervix; cervical intraepithelial neoplasia). To correlate time to recurrence of cervical dysplasia with T-cell function. Women with HIV infection are at greater risk for cervical dysplasia. Because of the likelihood that untreated or recurrent cervical dysplasia may progress to invasive cancer, there is an urgent need to develop appropriate therapies.

This study is to evaluate lot-lot consistency of Recombinant Human Papillomavirus Bivalent (Types 16, 18) Vaccine (Escherichia coli) .

Globally, cervical cancer is the second most common cancer for women and kills approximately 250,000 women every year, with the annual number of deaths expected to increase to 410,000 by 2030. The majority (88%) of these deaths occur in low- and middle-income countries (LMICs) where screening and prevention services are limited. Prevention of cervical cancer by identification and treatment of cervical cancer precursors is key, since treatment resources for invasive disease are scarce. A cervical cancer screening program cannot be effective unless it is linked with a proven intervention to prevent the development of cervical cancer. The World Health Organization (WHO) recently released the WHO guidelines for screening and treatment of precancerous lesions for cervical cancer prevention, which recommends a screen-and-treat approach for cervical cancer prevention, with cryotherapy being the first choice of treatment for women who have a positive screen. However, these programs are still slow to be implemented in part due to the current high cost and low efficiency of cryotherapy equipment that is often prone to breaking. Jhpiego, an affiliate of Johns Hopkins University, has developed a new cryotherapy device, CryoPop, that is one tenth the cost of current equipment while also ten times more efficient. Once proven safe, feasible and effective, CryoPop could save tens of thousands of lives in low- and middle-income countries each year by preventing cervical cancer.

Cervical cancer is a leading cause of mortality among women in developing countries. A key factor has been the failure to achieve good coverage. The development in the last years of HPV-DNA based tests has changed the scenario, because it combines a high performance to detect disease with a reduction of screening frequency. Through self-testing, HPV testing has the potential of reducing social and health service barriers faced by women to access screening. This study is carried out in Jujuy, one of the Argentinian provinces with highest cervical cancer mortality rates and where HPV testing has been introduced as a primary screening test for all women attending public health sector. The study was conducted between July 2012-December 2013, and supported by the Argentinean National Cancer Institute. The protocol was approved by the institutional review committees of the Ministry of Health of Jujuy. This trial is a randomized by population clusters study that aims to assess the effectiveness of self-testing to increase coverage. The aims of this study are: a) to assess the self-test effectiveness to increase the participation of women in screening programs, b) to assess the self-test acceptability by women, c) to assess HPV self-test effectiveness measurement for the detection of CIN2+ lesions against cytology in primary screening. An overall number of 200 community health workers (CHWs) from the Primary Health Care System (PHCS) of Jujuy will be randomized into two groups that will be named Self-test Group (ST) and Conventional Sample Group (CS): ST Group: CHWs will invite eligible women of their area to choose between doing a self-test or having a conventional sample taken by a health professional of the closest health care center. CS Group: CHWs will invite eligible women in their area to have a conventional sample taken by a health care professional of the nearest health care center. In order to measure the self-test relative sensitivity against cytology to detect CIN2+ in primary screening, all the women in the Self-test Group who have decided to do the self-test and all the women of 30 years of age and older that were screened with cytology by the provincial program for the prevention of cervical cancer in 2011 will be considered. A database built specifically for the study will be used; it will hold the list of eligible women to participate in the study. The records of women of 30 years of age and older residing in the areas included in the study will be imported from the PHCS databases. In addition, the data surveyed by the study will be uploaded: randomization Group, presence of the woman at home during the CHW's visit, agreement to participate in the study, realization of self-test (in the corresponding group), and if appropriate, reasons for not doing the self-test. Lastly, the HPV Test realization will be uploaded importing the data on SITAM, (link of data done as from the identity card number). Data Analysis Self-test acceptability: Acceptability is defined as the number of women accepting the self-test against the number of women offered the option between the self-test and the conventional sample (proportion of women accepting the self-test). The acceptability in this population will be estimated as the average of acceptabilities calculated by CHW, as to control the impact of the CHWs on acceptability and reach an appropriate variance estimate. Besides, the variability introduced by the CHWs on acceptability will be studied and the results obtained by male and female CHWs will be compared, as well as those obtained by the CHWs in rural and urban areas. Self-test effectiveness to enhance participation of women in screening and diagnosis: There will be a comparison of the percentage of women that did the HPV test in the Self-test group and the Conventional sample group. Three different coverage indicators will be considered for every CHW. These will be defined as the number of women screened within the field work regarding: The number of women reached by the CHW who accepted participating in the study. The number of eligible women for that CHW (regardless of whether the CHW was able to contact them or not). The effect of the strategy (offering the self-test option against promotion of the conventional sample) will be estimated for each one of the coverage measures using a means difference test or a non-parametric test for independent samples. CIN 2+ detection rate: The effectiveness of the HPV Self-test against screening cytology to detect CIN2+ will be estimated as the detection rates difference and as the detection rates ratio. In addition, there will be a comparison of the CIN2+ detection rate in the group of women who did the self-test against the total number of women in the province of Jujuy that were tested for HPV (conventional sample strategy + triage Pap test) until December 2012.

This study evaluated the long-term safety of quadrivalent Human Papillomavirus (HPV) types 6, 11, 16, 18 vaccine and its effectiveness in the prevention of cervical intraepithelial neoplasia (CIN), adenocarcinoma in situ, and cervical cancer related to HPV in Japanese women.

This study was designed to enable all subjects who received placebo in the HPV-039 study (NCT00779766), to also receive GSK Biologicals' Human Papillomavirus (Types 16, 18) Vaccine, Adsorbed. Safety data in terms of serious adverse events (SAEs), any adverse events (AEs)/SAEs leading to premature discontinuation of the study, potential immune mediated diseases (pIMDs) and pregnancies (and their outcomes) were collected during the study period. In addition, this study assessed the long term protective effect of the vaccine, in an exploratory manner, in terms of rates of HPV-related (vaccine type) incident cervical infection up to approximately 10 years after vaccination in subjects who participated in HPV-039 study (NCT00779766).

To evaluate the immune non-inferiority, as measured by antibody responses, of a 2-dose immunization schedule (0, 6 months) of recombinant human papillomavirus virus-like particle vaccine (type 16 and 18 L1 proteins, yeast) (hereinafter referred as HPV-2 vaccine) in adolescent females aged 9 to 14 years in comparison to 3-dose immunization schedule (0, 2, 6 months) in young females aged 18 to 26 years.
