Megavoltage CT (MVCT) Imaging for Intracavitary Radiation Treatment in Cervix Cancer
Cervix CancerThe Cross Cancer Institute has recently acquired a tomotherapy radiotherapy treatment machine; the first of its kind in Canada. It has the potential to improve cancer treatment outcomes where radiotherapy is used. Cervix cancer is a disease where radiotherapy is a particularly important treatment modality. The researchers believe that by combining tomotherapy (which has the ability to give higher doses of radiation to areas of cancer while sparing normal tissues) with radiotherapy given from inside the uterus and vagina (brachytherapy) disease outcomes will be improved. For this to be possible the researchers will need to accurately map the doses of radiation given to the cervix, uterus and other pelvic organs from these two types of radiation treatment. As well as being used for treatment, the tomotherapy machine can also be used for taking medical images by using very much lower doses of radiation. This study will allow the researchers to develop the mapping process by using very low doses of radiation on the tomotherapy unit to take medical x-ray images of patients being treated by brachytherapy for cervix cancer. In this special circumstance the researchers expect the images to be of a higher quality than for conventional computed tomography (CT) scanning or magnetic resonance imaging (MRI) scanning.
Re-Evaluation of Annual Cytology Using HPV Testing to Upgrade Prevention in Women Living With HIV...
Cervical CancerHPV Infection1 moreCurrent British HIV Association (BHIVA) guidelines recommend annual cervical screening (with a cervical smear) for women living with HIV (WLWH). NHS guidelines for women in England will, however, change soon. Women will initially be tested for human papilloma virus (HPV), a virus which causes virtually all cervical cancer. Only those who are infected with HPV will then undergo the smear testing. The BHIVA guidelines, however, taking the view that HIV infection (and its ability to weaken the immune system) increases the risk of persistent HPV infection and of cancer in those who are infected, consider safer for all WLWH to go straight to annual smear testing. Most WLWH in the UK are now receiving treatment which protects their immune system - this suggests that less WLWH could be HPV infected. The identification of a group of WLWH who could benefit from less frequent screening could improve quality of life, and allow the NHS to reduce unnecessary tests and costs. A large study is needed to collect robust evidence that would support changes to standard practice. Before investing huge resources, the investigators need to know if a study would be feasible, conducting a pilot study on 70 WLWH aged 25-64, regularly attending clinics for HIV care. Participants will be asked to complete an entry survey and they will undergo routine cervical smears (baseline and after 1 year). At baseline, after six months, and one year women will take their own vaginal swabs for the detection of HR-HPV. An exit questionnaire will be undertaken at the last visit.
Impact of the COVID-19 Pandemic in Gynecological Oncology
Gynecologic CancerBreast Neoplasm Female5 moreThe current infection with the Coronavirus SARS-CoV-2 (COVID-19) is an exceptional health situation which requires an adaptation of our management practices in gynecological oncology. Data from the literature suggest that infection with Coronavirus is serious in subjects with cancer with a risk of severe form 5 times higher than that of the population without cancer and a risk of death multiplied by 8. In addition, the risk of infection would be 3 times greater in case of cancer. Faced with the COVID-19 epidemic, the investigator must organize themselves to ensure continuity in the treatment of patients with gynecological cancer but also adapt our practices in the management (CPR, teleconsultation, adaptation of treatment or even postponement of treatment). The objective of the High Council of Public Health is to be able to ensure adequate oncological care avoiding any potential loss of chance concerning the care of cancer: people affected must, despite the pandemic, have care allowing the same level of curability (localized cancers) or the same life expectancy (advanced cancers). This must be done by limiting as much as possible the impact on the organization of the service, the organization of patient follow-up and the psychological impact that these possible modifications could have. The hypotheses of our study are that the exceptional health situation linked to this pandemic leads to a change in the care of patients with gynecological cancer associated with a psychological impact and increased anxiety of patients during their care. Despite the extent of the pandemic, very little existing data makes it possible to define recommendations with a sufficient level of evidence.
Cervical Cancer in French Guiana: Screening Between 2006-2011
Cervical CancerGiven that cervical cancer is the second most frequent cancer among women in french guiana the aim of the study was to determine the screening rate among women living in French Guiana. Cervical smears are read in 2 laboratories which allowed us to compute screening rates per 100 women-years. overall the screening activity was 23.5-25.8 smears per 100 women-years. between 2006 and 2011 54% of women were screened. These baseline figures will allow to evaluate present efforts to increase the screening rate for this frequent cancer in French Guiana.
Evaluation of the Effectiveness of the Video Prepared to Raise Cervical Cancer Awareness in Women...
Being a Woman Aged 18-65This research, a quasi-experimental study based on the comparison of the pre-test and post-test results of individuals in a single group is conducted to raise awareness about cervical cancer in women aged 18-65 years. The questionnaire includes 32 questions about the individual's socio-demographic characteristics, pregnancy, and sexual life information, cervical cancer, pap-smear test, and HPV vaccine information, as well as a 27-item 3-point likert type to measure cervical cancer risk factors, symptoms, and prevention. A survey form consisting of 61 questions, consisting of 2 questions and 2 guestions for evaluating the animated training video, and an informative animated training video of 4 minutes and 33 seconds constituted the data collection tools. During the Covid-19 pandemic, the study has completed with 433 people who participated voluntarily by directing the participants via online platforms (WhatsApp / Instagram / E-mail) using the snowball sampling method of survey applications. The women who participated in the research completed the first part by watching the informative animated training video at the end of the questionnaire form.
Predictors of Para-aortic Lymph Node Metastasis of Cervical Cancer
Locally Advanced Cervical CancerThe goal of this observational study is to identify predictive factors and to develop a risk model predicting para-aortic lymph node metastasis in patients with locally advanced cervical cancer based on the analysis of surgical staging results. The main questions it aims to answer are: What are the risk factors to predict para-aortic lymph node metastasis in patients with locally advanced cervical cancer? What is the indication for prophylactic extended-field radiation therapy in patients with locally advanced cervical cancer Individual data of patients with locally advanced cervical cancer treated with surgical staging at our institution from 2020 to 2022 were pooled analysed.Multivariate Logistic regression analysis was used to identify the predictive factors and to develop the prediction model.
Community Awareness, Resources and Education (CARE II) Project: Project 1
Cervical CancerThe study hypothesis is that the increased incidence of cervical cancer observed in Appalachian women over their non-Appalachian counterparts is due in part to inherited and somatic alterations of key components of the Transforming Growth Factor β (TGFβ) signaling pathway.

Low-Cost Molecular Cervical Cancer Screening Study
DNA ProbesE6 Protein2 moreBackground: - Low-cost molecular human papillomavirus (HPV) testing may offer a more robust alternative to Pap smears and visual inspection for cervical cancer screening of underserved women. Two low-cost molecular tests for human HPV, the HPV E6 Test and the careHPV test, have been developed to detect cervical cancer by testing for HPV DNA. These tests take between 2 and 3 hours to run and may provide point-of-care (diagnostic testing at or near the site of patient care) testing for HPV. Researchers are interested in evaluating both tests to determine the best strategy for HPV testing of women who live in rural or underserved areas that have a high prevalence of cervical cancer diagnoses. Objectives: To evaluate the clinical performance of the HPV E6 Test and careHPV in detecting cervical cancer and precancerous lesions. To evaluate the best low-cost test or combination of tests for women who have been referred for cervical cancer screening or treatment. To compare the clinical performance of self-collected specimens versus clinician-collected specimens in detecting cervical cancer and precancerous lesions. Eligibility: - Women between 25 and 65 years of age who live in rural China. Design: This study involves an initial testing visit and a 1-year followup visit for a high-risk subgroup. Participants will have the HPV E6 test, careHPV, and a visual inspection test for cervical cancer. For comparison, participants will also have the standard HPV test approved by the U.S. Food and Drug Administration. Participants who test positive for HPV on any of the above tests will also have colposcopy to collect samples of cervical tissue for further study. A random sample of women who test negative for HPV will also have colposcopy. Participants may also have biopsies if there is visual evidence of cervical abnormalities. At the 1-year followup visit, participants in the high-risk subgroup will have the same tests as in the previous visit..
