Attitudes About Childbearing And Fertility With Inherited Breast And Ovarian Cancer Syndromes (HBOC)...
Breast CancerOvarian CancerObjectives: - To evaluate the attitudes and opinions of women undergoing genetic counseling for hereditary breast and ovarian cancer syndrome, both before and after testing, in regards to pregnancy and fertility Hypothesis: -Factors that will increase the percentage of women endorsing prenatal diagnostic testing will include a personal history of breast or ovarian cancer, having had a mother or sister die of breast or ovarian cancer, and testing positive for a BRCA mutation.
Genetic Studies in Breast Cancer
Breast CancerOvarian CancerThe purpose of this study is to determine the specific genetic alterations associated with breast cancer. This will leat to a better understanding of the genetic causes of breast cancer.
Contrast-Enhanced Ultrasound Ability in the Characterization of Ovarian Masses
Ovarian TumorThis study intends to assess the ability of contrast-enhanced ultrasound in the detection of benign and malignant ovarian masses compared to unenhanced ultrasound. By using an intravascular contrast agent, this noninvasive and feasible imaging technique will allow the investigators to define specific microcirculation patterns in 100 women with ovarian lesions. The intravascular contrast agent properties will be compared between benign and malignant adnexal masses. The final purpose of this ultrasonography is to allow the early detection of tumors and to improve the characterization between benign and malignant lesions.
An Analysis of the Response of Human Tumor Microvascular Endothelium to Ionizing Radiation
Ovarian NeoplasmsColorectal Neoplasms3 moreDoctors will take some tissue from the tissue removed during surgery in order to study how the blood vessels of the tumor respond to radiation therapy. The tissue obtained will be used to determine how these tumor blood vessels respond to radiation therapy delivered to the tumor, after it has been removed. This radiation is delivered in the research lab. This research is being conducted in order to develop new methods to treat tumors by radiation therapy. No additional surgery will be performed to obtain these samples, and only materials that remain after all diagnostic testing has been completed will be used.
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.
Cell-free DNA Methylation for Epithelial Ovarian Cancer
Epithelial Ovarian CancerDNA Methylation5 moreLiquid biopsy is challenging for the diagnosis of epithelial ovarian cancer (EOC). In this study, we performed the methylation testing of host DNA, namely, OPCML, FODX3 and CDH13, in the peripheral serum to discover the diagnostic and supervision roles of DNA methylation in EOC patients. The study compromises two stages. In the training set, DNA methylation testing is performed in the ovarian tissues from EOC and paired benign ovarian tumor patients. The cut-off values of methylation are produced in this stage. On the meantime, serum DNA methylation testing is also performed to reveal its accordance and accuracy compared with the results of ovarian tissues. In the validation set, serum DNA methylation testing is performed in unselected ovarian tumor patients with definite cut-off values to validate its accuracy based on known histology of ovarian tumors. In training and validation sets, serum DNA methylation is also performed after major surgeries for EOC as to illustrate the changes of methylation testing, therefore, reflection the supervision role of DNA methylation.
Plasma ctDNA Detection in Diagnosis of Epithelial Ovarian Cancer.
Epithelial Ovarian CancerEpithelial ovarian cancer constitutes one of the most common gynecological malignancies.Because the ovaries lie in the deep pelvic cavity,most ovarian cancer patients are asymptomatic, rendering the majority often diagnosed at an advanced stage.ctDNA in cancer patients often bears similar genetic and epigenetic features to the related tumor DNA.This study aims to detect plasma ctDNA in Diagnosis of Epithelial Ovarian Cancer.
EURAD MRI Classification of US Indeterminate Adnexa Lesions
Ovarian TumorThis research is targeting patients with sonographically indeterminate adnexal mass that are being referred for clinical MR imaging. Investigators from the UW will be contributing coded MR images and associated health information (US results, laboratory/pathology results) to the EURAD trial. In addition, outcomes data on each patient will be sent at month 24 of the research.
Clinical Impact of Dedicated MR Staging of Ovarian Cancer
Ovarian CancerThe only chance of cure for patients with advanced stage ovarian cancer is complete cytoreductive surgery (CRS). The only way to determine whether complete CRS can be achieved is by a laparoscopy. However, diffusion-weighted magnetic resonance imaging (DW-MRI) has a very high sensitivity to detect small volume malignant disease, making it a potentially suitable staging tool. Aim of this study is to determine the performance of DW-MRI for predicting whether complete CRS can be achieved.
Study of Predictive Factors of Chemoresistance in Ovarian Cancer
Ovarian CancerEpithelial ovarian cancer (EOC) has a poor prognosis. EOC management requires debulking surgery and chemotherapy based on taxol and carboplatine. Initial response is often good, but most often a recurrence occurred in the first 18 months. Early recurrence signs chemoresistance and palliative treatment. The study of predictive clinical or biological factors is required to adapt therapeutic and develop new treatments.
