                    There are different types of treatment for patients with adult ALL.
                    Different types of treatment are available for patients with adult acute lymphoblastic leukemia (ALL). 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.
                
                
                    The treatment of adult ALL usually has two phases.
                    The treatment of adult ALL is done in phases:         -  Remission induction therapy: This is the first phase of treatment. The goal is to kill the leukemia cells in the blood and bone marrow. This puts the leukemia into remission.    -  Post-remission therapy: This is the second phase of treatment. It begins once the leukemia is in remission. The goal of post-remission therapy is to kill any remaining leukemia cells that may not be active but could begin to regrow and cause a relapse. This phase is also called remission continuation therapy.        Treatment called central nervous system (CNS) sanctuary therapy is usually given during each phase of therapy. Because standard doses of chemotherapy may not reach leukemia cells in the CNS (brain and spinal cord), the cells are able to "find sanctuary" (hide) in the CNS. Systemic chemotherapy given in high doses, intrathecal chemotherapy, and radiation therapy to the brain are able to reach leukemia cells in the CNS. They are given to kill the leukemia cells and lessen the chance the leukemia will recur (come back). CNS sanctuary therapy is also called CNS prophylaxis.
                
                
                    Four types of standard treatment are used:
                    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 (intrathecal chemotherapy), 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.    Intrathecal chemotherapy may be used to treat adult ALL that has spread, or may spread, to the brain and spinal cord. When used to lessen the chance leukemia cells will spread to the brain and spinal cord, it is called central nervous system (CNS) sanctuary therapy or CNS prophylaxis.        See Drugs Approved for Acute Lymphoblastic Leukemia 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 of cancer. External radiation therapy may be used to treat adult ALL that has spread, or may spread, to the brain and spinal cord. When used this way, it is called central nervous system (CNS) sanctuary therapy or CNS prophylaxis. External radiation therapy may also be used as palliative therapy to relieve symptoms and improve quality of life.       Chemotherapy with stem cell transplant     Stem cell transplant is a method of giving 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 body's blood cells.    See Drugs Approved for Acute Lymphoblastic Leukemia 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.    Targeted therapy drugs called tyrosine kinase inhibitors are used to treat some types of adult ALL. These drugs block the enzyme, tyrosine kinase, that causes stem cells to develop into more white blood cells (blasts) than the body needs. Three of the drugs used are imatinib mesylate (Gleevec), dasatinib, and nilotinib.    See Drugs Approved for Acute Lymphoblastic Leukemia 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.     Biologic therapy     Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
                
                
                    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.
                
                
                    Patients with ALL may have late effects after treatment.
                    Side effects from cancer treatment that begin during or after treatment and continue for months or years are called late effects. Late effects of treatment for ALL may include the risk of second cancers (new types of cancer). Regular follow-up exams are very important for long-term survivors.
                
                
                    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.
