Filter by:This study will be looking at what dose of the TA-CIN vaccine is safe and effective in patients with a history of HPV16-associated cervical cancer.
The purpose of this study is to assess the acceptability and effectiveness of utilizing vaginal self-swabs for HPV DNA testing as compared to provider-collected cervical swabs for HPV, as well as to investigate the prevalence of other Sexually Transmitted Infections (STIs) among sexually active female-to-male (FTM) transgender adults.
The proposed study seeks to compare the diagnostic performance of Human Papillomavirus (HPV) testing in self-collected samples via the Eve Medical self-collection system© (Eve) with standard physician-collected samples for the detection of cervical intraepithelial neoplasia grade 1 or worse (CIN1+) and cervical cancer among women referred for colposcopy. The performance of the Eve sample will also be compared with that of a second self-sample via a cobas® PCR Female swab. Approximately 1000 adult women with an abnormal Pap test at the level of an atypical squamous cells of undetermined significance or worse squamous or glandular abnormality (i.e., ASCUS+) or an abnormal co-test (ASCUS+ and HPV-positive) result will be recruited over a period of 12 months via colposcopy clinics located at the Jewish General Hospital, St-Mary's Hospital, and the McGill University Health Centers (Royal Victoria Hospital). Participating women will undergo three cervical or cervicovaginal sampling techniques: 1) self-sampling using the Eve Medical self-collection system©; 2) self-sampling using a cobas® PCR Female swab; and 3) physician-collected sampling. The participants will also fill in a questionnaire on their experience with the convenience and acceptability of the Eve system, relative to the other two sampling approaches. The decision as to which self-sample is to be collected first will be dependent on randomization HPV testing will be done using the cobas® 4800 HPV Test. The liquid medium of within the cobas® PCR CELL Collection Media with the provider collected sample and the cobas® PCR media with the two self-collected samples will be used to suspend the cellular material prior to HPV testing. We have made collaborative arrangements with Dr. Marcel Behr, Chief of the Department of Clinical Microbiology at the McGill University Health Centre for the HPV genotyping work. Histology-confirmed CIN1+ will form the study outcome or case definition. Sensitivity, specificity, and predictive values (along with their respective 95% confidence intervals) will be calculated for each sample type to evaluate the clinical performance of the various sampling techniques. We will use CIN1+ as definition of disease but analyses will also be performed for more stringent definitions, e.g. CIN2+ or CIN3/cancer.
Cervical cancer remains an important health problem worldwide. Poor tumor oxygenation (hypoxia) is associated with inferior survival in cervical cancer and resistance to radiation treatment. Hypoxia-modifying therapies improve survival, but existing therapies are impractical and/or toxic. Metformin, a non-toxic drug for diabetes, has been shown to decrease tumor hypoxia in animal studies and its use is associated with better survival in diabetic cancer patients. It is hypothesized that metformin may decrease cervical tumor hypoxia and thereby improve tumor response to radiation and survival in patients with locally advanced cervix cancer. This is a randomized, multicenter phase II study of standard chemoradiation in combination with metformin versus standard chemoradiation alone in women with locally advanced cervix cancer. Women randomized to the metformin group will take metformin starting 1 week prior to standard chemoradiation and throughout the duration of external radiation treatment. Tumor hypoxia will be measured by a special X-ray test called positron emission test (PET) performed with a hypoxia dye called FAZA. The main purpose of this study is to see if metformin decreases tumor hypoxia measured on FAZA-PET; information about response and side effects will also be collected.
The addition of concurrent chemotherapy to definitive radiation has improved the 5-year survival of women with locally advanced cervical cancer to 58%. To determine if plasma HPV DNA predates clinical recurrence and/or improves the accuracy of metabolic response on FDG-PET at 3 months post completion of radical chemo-radiation in patients with locally advanced cervical cancer. Post therapy FDG-PET can help predict progression free survival and overall survival. In addition plasma HPV can be used to monitor response and detect early recurrence. Prospective study will recruit 20 patients with locally advanced cervical cancer to determine if plasma HPV DNA predates clinical recurrence and/or improves the accuracy response on post-therapy FDG-PET scan at 3 months.
The study's aim is to define imaging and molecular bio-markers for prediction of radiotherapy response of squamous cell carcinomas, in an early treatment phase.
Several reasons can explain non-attendance in cervical cancer screening. In low resource settings the attendance is even lower. The effect of fee as contributing reason of non attendance has not been studied before why the investigators decided to study this in a low resource setting as a randomised trial.
The purpose of this study is to evaluate the implementation and effectiveness of text messages as a means for improving adherence to cervical cancer screening.
Based on the value-based medicine, a randomized clinical trial was conducted to compare the role of class II and class III hysterectomy in patients with low risk early staged cervical cancer (defined as tumor lesions less than 2cm with less than 50% stromal invasion).
Our goal is to evaluate, in France, the effectiveness (in terms of participation) of the general practitioner involvement (signature) and a more personalized communication in invitation letters to organized screening of breast, colorectal and cervical cancers. The hypothesis on which this project is based is that communication is probably more effective if the "receiver" feels personally targeted by invitation letters (Dear Martin, I am writing ...) and if he knows "the issuer "(his general practitioner rather an unknown person).
