                    There are different types of treatment for patients with ovarian germ cell tumors.
                    Different types of treatment are available for patients with ovarian germ cell tumor. Some treatments are standard (the currently used treatment), 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 standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
                
                
                    Four types of standard treatment are used:
                    Surgery     Surgery is the most common treatment of ovarian germ cell tumor. A doctor may take out the cancer using one of the following types of surgery.             -  Unilateral salpingo-oophorectomy: A surgical procedure to remove one ovary and one fallopian tube.      -  Total hysterectomy: A surgical procedure to remove the uterus, including the cervix. 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.     -  Bilateral salpingo-oophorectomy: A surgical procedure to remove both ovaries and both fallopian tubes.     -  Tumor debulking: A surgical procedure in which as much of the tumor as possible is removed. Some tumors cannot be completely removed.            Even if the doctor removes all the cancer that can be seen at the time of the operation, some patients may be offered chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.    After chemotherapy for an ovarian germ cell tumor, a second-look laparotomy may be done. This is similar to the laparotomy that is done to find out the stage of the cancer. Second-look laparotomy is a surgical procedure to find out if tumor cells are left after primary treatment. During this procedure, the doctor will take samples of lymph nodes and other tissues in the abdomen to see if any cancer is left. This procedure is not done for dysgerminomas.       Observation     Observation is closely watching a patients condition without giving any treatment unless signs or symptoms appear or change.        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). Combination chemotherapy is treatment using more than one anticancer drug. 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.       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. There are two types of radiation therapy:            -  External radiation therapy uses a machine outside the body to send radiation toward the cancer.     -  Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.           The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat ovarian germ cell tumors.
                
                
                    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.     High-dose chemotherapy with bone marrow transplant     High-dose chemotherapy with bone marrow transplant is a method of giving very high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the bodys blood cells.       New treatment options      Combination chemotherapy (the use of more than one anticancer drug) is being tested in clinical trials.
                
                
                    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.

		                    Stage I Ovarian Germ Cell Tumors
		                    Treatment depends on whether the tumor is a dysgerminoma or another type of ovarian germ cell tumor.    Treatment of dysgerminoma may include the following:          -  Unilateral salpingo-oophorectomy with or without lymphangiography or CT scan.     - Unilateral salpingo-oophorectomy followed by observation.     - Unilateral salpingo-oophorectomy followed by radiation therapy.    - Unilateral salpingo-oophorectomy followed by chemotherapy.        Treatment of other ovarian germ cell tumors may be either:          - unilateral salpingo-oophorectomy followed by careful observation; or    - unilateral salpingo-oophorectomy, sometimes followed by combination chemotherapy.        Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage I ovarian germ cell tumor. 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. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.
