Active clinical trials for "Ovarian Neoplasms"

Liquid 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.

Ovarian cancer is the fifth leading cause of cancer death in women worldwide. Most of these cancers are manifested in the form of an ovarian cyst. Practitioners are faced with two main difficulties. The first is to establish an early diagnosis. The second is to differentiate a benign tumor, a malignant tumor. To date, there is only one biological tumor marker routinely performed before an ovarian cyst, the CA-125 (cancer antigen 125). Unfortunately, many studies have been performed and show a sensitivity and specificity unsatisfactory in view of the severity of the disease. The principal investigator therefore propose to evaluate a new tumor marker, as well as its use in algorithms to help differentiate benign from malignant tumors, and allow earlier diagnosis in cases of ovarian cancer.

Ovarian carcinoma has poor prognosis and new therapeutic strategies are required. Many patients with ovarian carcinoma showed resistance to chemotherapy. Cleaved FasL is known for induced atypical response when is binding to Fas such as avoiding apoptosis and inducing cell motility.

ANGLE has developed the Parsortix™ Cell Separation System (Parsortix), an automated system capable of harvesting rare circulating cells for analysis from a sample of peripheral blood based on cellular size and deformability. In a small pilot study, scientists at the Medical University of Vienna demonstrated that measurement of a combination of mRNA markers extracted from CTCs captured using the Parsortix system could be used to identify women with ovarian cancer. This study is designed to provide specimens for optimization of an assay using clinical and biomarker information (i.e. demographics, imaging results and/or serum tumor markers) in combination with mRNA extracted from rare cells in the blood of women presenting with a pelvic mass for the detection of malignancy. Primary Objective: Optimization of an assay for the differentiation of women with benign pelvic masses from those with malignant pelvic masses using mRNA markers extracted from CTCs isolated from whole blood. Multiple serum tumor markers and mRNA markers will be measured, and the results will be compared to the actual clinical diagnosis made for each patient through other recognized methods (e.g. histopathology). The blood samples collected in the course of this study will be used to finalize the selection of mRNA and/or serum tumor markers to be evaluated in future prospective studies. Exploratory Objective: Use statistical modeling to determine the need for and/or preliminary design of a mathematical algorithm to combine the multiple serum tumor and/or mRNA markers for estimation of the risk of ovarian cancer.

A systematic literature search a goal-directed haemodynamic algorithm was created. The hypothesis of this study was that the goal-directed haemodynamic algorithm is feasible and can improve clinical outcome.

This clinical trial is studying the incidence of cancer in women at increased genetic risk of ovarian cancer. Gathering information about genetic factors in women with an increased risk of ovarian cancer over time may help doctors learn more about the disease and find better methods of treatment and on-going care.

Primary objectives: To develop peritoneal carcinomatosis index (PCI) for ovarian cancer, tubal cancer and primary peritoneal cancer that can represent perioperative intraperitoneal tumor burden objectively Secondary objectives: To establish the relationship and find out clinical significance between PCI, tumor location and tumor characteristics

This study will be the first prospective study enrolling consecutive patients with advanced ovarian cancer to determine the prevalence of thoracic and extra-abdominal involvement in this patient group and the relative value of gated PET and CT for diagnosing extra-abdominal involvement. This study will also answer a number of other stil unanswered questions: the impact of gating and the impact of gated PET on clinical management of patients with advanced ovarian cancer. This study also individualises patients' treatment to allow patients who may benefit most form optimal surgical cytoreduction and those who are better treated by neoadjuvant

The aim of this prospective registration and translational research study is to evaluate the praevalence of BRCA regarding germline and somatic mutations.

The purpose of this study is to determine what the immune response is of ovarian cancer patients in remission, when they are given the flu vaccine. After receiving the flu vaccine, patients will have blood drawn 5 times in 12 months to study antibody response to the flu vaccine.
