Types of Treatment for Acute Lymphocytic Leukemia (ALL)

Treatment for cancer is either local or systemic. Local treatments remove, destroy, or control the cancer cells in one area. When doctors direct it at one part of your body, radiation therapy is an example of local treatment. Doctors use systemic treatments to destroy or control cancer cells throughout your entire body. When you take it by mouth or injection, chemotherapy is an example of systemic treatment. In most cases, treatment for leukemia is systemic. That's because cancer cells are in your bloodstream throughout your body.

You may have just one type of treatment or a combination. Different types of treatment have different goals. Here are some of the types of treatment and their goals for adults who have acute lymphocytic leukemia (ALL).

Chemotherapy

This is the main way to treat ALL. Chemotherapy uses anticancer drugs to kill cancer cells. Its goal is to stop the growth of cancer cells, putting the cancer into remission and keeping it there. Sometimes a doctor injects chemotherapy drugs directly into your spinal fluid or brain to prevent cancer growth, or to reach cancer cells that may hide there. This is called intrathecal chemotherapy or central nervous system (CNS) prophylaxis. You may also have chemotherapy combined with a stem cell transplant. Stem cells restore blood cells lost during high-dose chemotherapy treatment.

Radiation Therapy

This type of therapy uses high-energy X-rays to kill cancer cells. Doctors may use radiation to kill or prevent the spread of cancer in your nervous system. They may also use it right before a stem cell transplant or, in rare cases, to shrink a tumor.

Stem Cell Transplant With High-Dose Chemotherapy

If the normal doses of chemotherapy don't work or your doctor feels you need a transplant to cure your disease, you may get very high doses of chemotherapy. These high doses can damage the stem cells in your bone marrow. Stem cells are the "starter" cells for all types of tissues, including blood cells. So sometimes before chemotherapy, a doctor removes some of your stem cells and freezes them, then returns them to you after treatment to restore your body's lost blood cells. Or you may receive stem cells from a donor. This is called a bone marrow stem cell transplant or peripheral blood stem cell transplant.

Targeted Therapy

Some newer drugs specifically target abnormal proteins, such as those caused by the Philadelphia chromosome. Drugs such as imatinib (Gleevec) and dasatinib (Sprycel) may be helpful in the treatment of ALL that has this chromosome. These drugs are taken daily as pills.
