About this study

Official title: The Role of Regulatory T Cell in Ovarian Cancer: Focus on Relationship Between

Cancer is the leading cause of mortality in our country, and ovarian cancer becomes a more and more important disease gradually in the field of gynecologic malignancies. According to the statistics of the Department of Health, the incidence of ovarian cancer increased in recent years and the mortality rate was the highest among all gynecologic malignancies in Taiwan. Early diagnosis for ovarian cancer is difficult due to the lack of obvious and specific initial symptoms. Therefore, it is usually at advanced stage when the diagnosis is confirmed. The prognostic parameters for ovarian cancer include tumor stage, histological subtype and grade, residual tumor after surgical intervention and the response to chemotherapy. However, the possible mechanism of ovarian cancer is still not clear now, which has considerable influence on the management and prognosis of the patients.

Malignancy is considered as a multi-factorial disease, and the influence of immunologic mechanism on progression and prognosis of cancer is more and more important. The natural CD25+CD4+ regulatory T cells actively suppress pathologic and physiological immune response, contributing to the maintenance of immunological self-tolerance and immune homeostasis. The development and function of regulatory T cells depend on the expression of the transcription factor forkhead box P3 (FOXP3). The mechanisms of suppression are still not known well. Whatever the mechanisms of suppression are, it is necessary to control the magnitude of regulatory T cells-mediated suppression for the benefit of the host because too much suppression might lead to immunosuppression and render the host susceptible to infection and cancer.

We will collect the tumor tissue, ascites and peripheral blood during operation. Through this research we will set up the immunological profiles in the changes of lymphocytes, humoral immunity and cell-mediated immunity in ovarian cancer patients. The kinetic changes and associations between regulatory T cells and the severity and progression of disease will also be evaluated. Therefore, the role of regulatory T cells would be defined in the patients with ovarian cancer. We will also correlate the regulatory T cells with the clinical prognosis of ovarian cancer patients. Finally, we will try to find an efficient therapeutic strategy for the cancer patients.

Methods:

All of the patients received four to six courses of adjuvant platinum-containing chemotherapy.Histologic grading was according to International Union against Cancer criteria (28). The stage of disease was classified according to the International Federation of Gynecology and Obstetrics (FIGO, 1987). Pelvic and paraaortic lymph node samplings will be performed, if the disease will be confined to within the ovary or will be without a ruptured capsule. The histopathologic data, including histologic type and histologic grade, will be evaluated by a certified pathologist. The maximal diameter of the residual tumor after surgery will be also recorded. All patients will be followed up at 3-month intervals.

Questions about this trial

What is this clinical trial studying?

A study testing Staging surgery or debulking surgery in people with Ovarian Cancer, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 3 Mar 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Wen-Fang Cheng, Associated Professor (886-2-23123456 ext. 65166, wenfangcheng@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

overall survival (time frame: from disease diagnosis to death). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2009.
