There are different types of treatment for patients with testicular cancer. Different types of treatments are available for patients with testicular cancer. 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. Testicular tumors are divided into 3 groups, based on how well the tumors are expected to respond to treatment. Good Prognosis For nonseminoma, all of the following must be true: - The tumor is found only in the testicle or in the retroperitoneum (area outside or behind the abdominal wall); and - The tumor has not spread to organs other than the lungs; and - The levels of all the tumor markers are slightly above normal. For seminoma, all of the following must be true: - The tumor has not spread to organs other than the lungs; and - The level of alpha-fetoprotein (AFP) is normal. Beta-human chorionic gonadotropin (-hCG) and lactate dehydrogenase (LDH) may be at any level. Intermediate Prognosis For nonseminoma, all of the following must be true: - The tumor is found in one testicle only or in the retroperitoneum (area outside or behind the abdominal wall); and - The tumor has not spread to organs other than the lungs; and - The level of any one of the tumor markers is more than slightly above normal. For seminoma, all of the following must be true: - The tumor has spread to organs other than the lungs; and - The level of AFP is normal. -hCG and LDH may be at any level. Poor Prognosis For nonseminoma, at least one of the following must be true: - The tumor is in the center of the chest between the lungs; or - The tumor has spread to organs other than the lungs; or - The level of any one of the tumor markers is high. There is no poor prognosis grouping for seminoma testicular tumors. Five types of standard treatment are used: Surgery Surgery to remove the testicle (inguinal orchiectomy) and some of the lymph nodes may be done at diagnosis and staging. (See the General Information and Stages sections of this summary.) Tumors that have spread to other places in the body may be partly or entirely removed by surgery. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given 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. 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 testicular cancer. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells 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). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Testicular Cancer for more information. Surveillance Surveillance is closely following a patient's condition without giving any treatment unless there are changes in test results. It is used to find early signs that the cancer has recurred (come back). In surveillance, patients are given certain exams and tests on a regular schedule. High-dose chemotherapy with stem cell transplant High-dose chemotherapy with stem cell transplant is a method of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or 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. See Drugs Approved for Testicular Cancer for more information. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. 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. Men who have had testicular cancer have an increased risk of developing cancer in the other testicle. A patient is advised to regularly check the other testicle and report any unusual symptoms to a doctor right away. Long-term clinical exams are very important. The patient will probably have check-ups frequently during the first year after surgery and less often after that. Treatment Options by Stage Stage 0 (Testicular Intraepithelial Neoplasia) Treatment of stage 0 may include the following: - Radiation therapy. - Surveillance. - Surgery to remove the testicle.

answer:Key Points - Hairy cell leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). - Leukemia may affect red blood cells, white blood cells, and platelets. - Gender and age may affect the risk of hairy cell leukemia. - Signs and symptoms of hairy cell leukemia include infections, tiredness, and pain below the ribs. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose hairy cell leukemia. - Certain factors affect treatment options and prognosis (chance of recovery). Hairy cell leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Hairy cell leukemia is a cancer of the blood and bone marrow. This rare type of leukemia gets worse slowly or does not get worse at all. The disease is called hairy cell leukemia because the leukemia cells look "hairy" when viewed under a microscope. Leukemia may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to stop bleeding. A lymphoid stem cell becomes a lymphoblast cell and then into one of three types of lymphocytes (white blood cells): - B lymphocytes that make antibodies to help fight infection. - T lymphocytes that help B lymphocytes make antibodies to help fight infection. - Natural killer cells that attack cancer cells and viruses. In hairy cell leukemia, too many blood stem cells become lymphocytes. These lymphocytes are abnormal and do not become healthy white blood cells. They are also called leukemia cells. The leukemia cells can build up in the blood and bone marrow so there is less room for healthy white blood cells, red blood cells, and platelets. This may cause infection, anemia, and easy bleeding. Some of the leukemia cells may collect in the spleen and cause it to swell. This summary is about hairy cell leukemia. See the following PDQ summaries for information about other types of leukemia: - Adult Acute Lymphoblastic Leukemia Treatment. - Childhood Acute Lymphoblastic Leukemia Treatment. - Chronic Lymphocytic Leukemia Treatment. - Adult Acute Myeloid Leukemia Treatment. - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment. - Chronic Myelogenous Leukemia Treatment.

answer:Gender and age may affect the risk of hairy cell leukemia. Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. The cause of hairy cell leukemia is unknown. It occurs more often in older men.
