                    There are different types of treatment for patients with ovarian epithelial cancer.
                    Different types of treatment are available for patients with ovarian epithelial cancer. Some treatments are standard, and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the treatment currently used as standard treatment, the new treatment may become the standard treatment. Patients with any stage of ovarian cancer may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

                    Surgery     Most patients have surgery to remove as much of the tumor as possible. Different types of surgery may include:            -  Hysterectomy: Surgery to remove the uterus and, sometimes, the cervix. When only the uterus is removed, it is called a partial hysterectomy. When both the uterus and the cervix are removed, it is called a total hysterectomy. If the uterus and cervix are taken out through the vagina, the operation is called a vaginal hysterectomy. If the uterus and cervix are taken out through a large incision (cut) in the abdomen, the operation is called a total abdominal hysterectomy. If the uterus and cervix are taken out through a small incision (cut) in the abdomen using a laparoscope, the operation is called a total laparoscopic hysterectomy.     -  Unilateral salpingo-oophorectomy: A surgical procedure to remove one ovary and one fallopian tube.     -  Bilateral salpingo-oophorectomy: A surgical procedure to remove both ovaries and both fallopian tubes.     -  Omentectomy: A surgical procedure to remove the omentum (tissue in the peritoneum that contains blood vessels, nerves, lymph vessels, and lymph nodes).      - Lymph node biopsy: The removal of all or part of a lymph node. A pathologist views the tissue under a microscope to look for cancer cells.              Chemotherapy     Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).     A type of regional chemotherapy used to treat ovarian cancer is intraperitoneal (IP) chemotherapy. In IP chemotherapy, the anticancer drugs are carried directly into the peritoneal cavity (the space that contains the abdominal organs) through a thin tube.     Treatment with more than one anticancer drug is called combination chemotherapy.    The way the chemotherapy is given depends on the type and stage of the cancer being treated.    See Drugs Approved for Ovarian, Fallopian Tube, or Primary Peritoneal Cancer for more information.       Targeted therapy     Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells.     Monoclonal antibody therapy is a type of targeted therapy that uses antibodies made in the laboratory, from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells.     Bevacizumab is a monoclonal antibody that may be used with chemotherapy to treat ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer that has recurred (come back).     Poly (ADP-ribose) polymerase inhibitors (PARP inhibitors) are targeted therapy drugs that block DNA repair and may cause cancer cells to die. Olaparib and niraparib are PARP inhibitors that may be used to treat advanced ovarian cancer.     See Drugs Approved for Ovarian, Fallopian Tube, or Primary Peritoneal Cancer for more information.
                
                
                    New types of treatment are being tested in clinical trials.
                    This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.     Radiation therapy     Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. Some women receive a treatment called intraperitoneal radiation therapy, in which radioactive liquid is put directly in the abdomen through a catheter. Intraperitoneal radiation therapy is being studied to treat advanced ovarian cancer.       Immunotherapy     Immunotherapy is a treatment that uses the patients immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the bodys natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.     Vaccine therapy uses a substance to stimulate the immune system to destroy a tumor. Vaccine therapy is being studied to treat advanced ovarian cancer.
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
                
                
                    Follow-up tests may be needed.
                    Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.   Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

		                    Early Ovarian Epithelial and Fallopian Tube Cancer
		                    Treatment of early ovarian epithelial cancer or fallopian tube cancer may include the following:         -  Hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. Lymph nodes and other tissues in the pelvis and abdomen are removed and checked under a microscope for cancer cells. Chemotherapy may be given after surgery.    -  Unilateral salpingo-oophorectomy may be done in certain women who wish to have children. Chemotherapy may be given after surgery.        Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage I ovarian epithelial cancer and fallopian tube cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.
