leukemias

AML is usually treated with chemotherapy drugs -- drugs that are toxic to the leukemia cells and stop them from growing. Chemotherapy is given in several stages. The first stage is called induction therapy. The goal of induction therapy is to put the disease in remission -- to kill close to 99 percent of the abnormal cells and allow normal blood cell production to resume.

Chemotherapy also kills normal cells. As a result, patients may feel nauseous and tired, and be prone to more infections. Several chemotherapy drugs are used together, so if any cells are resistant to one of the drugs, those cells will be targeted by the other drug.

AML Treatment Facts

  • The first treatment phase is called remission induction. Chemotherapy drugs are used to achieve cancer remission, the state in which there is no clinical evidence of disease and blood counts are normal. The remission induction therapy for children is generally daunorubicin and cytarabine given over the course of seven to ten days. Other drugs such as thioguanine or etoposide may be added.

  • Even if the central nervous system (CNS) shows no clinical evidence of disease, treatment of that area with cytarabine is also recommended. This drug is usually administered directly to the cerebrospinal fluid. Preventive chemotherapy for the CNS is commonly recommended for children. Irradiation is used to treat disease that has entered the CNS, and irradiation may also be used to prevent CNS involvement.

  • Treatment following remission induction may be bone marrow transplantation using an HLA-matched sibling. To learn more about stem cell transplants, you may wish to order the Memorial Sloan-Kettering Cancer Center CD-ROM program entitled Bone Marrow and Stem Cell Transplantation. Transplantation may not be recommended for the rare child who generally does well with standard treatment. In this case, the child may receive intensive-dose cytarabine followed by two to six months of combination chemotherapy.

Treatment Decisions

Most patients, adults and children, will be treated according to cooperative group protocols. Often these will be clinical trials seeking to improve outcomes. Some drugs are more effective against specific subtypes of leukemia, and treatments are often based on the patient's specific gene mutation. Your doctor will discuss this during the treatment consultation following immunophenotyping and other diagnostic tests.

During Treatment

Side effects during remission induction can be significant, and patients usually remain in the hospital for a period of four to six weeks. Treatment for AML is aimed at the leukemic blood cells, but normal blood cells are also affected by chemotherapy treatment. All patients undergoing treatment will experience lowered blood counts that lead to a variety of symptoms.

Low white blood cell counts put patients at increased risk of infection. Treatment with antibiotics to prevent or treat infection is likely. In some situations, the patient will be in isolation, and visitors to the patient's room may need to wear gowns, masks, and gloves to reduce the risk of infection.

Low white blood cell counts generally also lead to inflammation of the mucous membranes in the mouth and gastrointestinal tract. This is called mucositis. The tissues become very dry and may crack or bleed. Specific oral care regimens help minimize discomfort and prevent secondary infections. Mouth sores can make eating painful. The mouth sores themselves can cause pain that requires pain medication.

Nausea, vomiting, and diarrhea are side effects for which effective treatments exist. Hair may fall out, and this is can be an especially upsetting side effect. Wigs and scarves may help minimize the distress hair loss causes.

Low platelet counts lead to easy bruising and bleeding. Taking care to prevent injuries is very important. Low red blood cell counts causing anemia make patients feel tired and weak. Sometimes, patients may be short of breath or experience a fast heartbeat rate. Transfusions will be necessary to replace red blood cells and platelets. Many patients are given stimulating factors called G-CSF or GM-CSF. These stimulate the development of new white blood cells so that cell counts are low for a shorter period of time.

The initial course of treatment and the severity of side effects can be very difficult and wearing on patients. While blood counts are low, your child may find it difficult to carry on normal activities. *Simple exercise, such as walking, may seem overwhelming. Your doctors and nurses will do everything in their power to minimize the discomfort, sadness, and boredom that are common during this initial phase of treatment. Social workers, psychiatrists, and psychologists can help you and your child with depression and the ups and downs you will experience during treatment. Social workers can also help with financial issues related to treatment. Finally, all hospitals have clergy who are available to speak to you and provide spiritual support and guidance.

Resuming Activities

After the initial hospitalization, patients will slowly begin to resume their normal activities, but school may have to be postponed for many months. Subsequent shorter hospital stays, ranging from one to two weeks, may be necessary to administer chemotherapy and treat infections that result from low white blood cell counts. Strength and stamina will return gradually. The doctors and nurses will provide more specific guidelines on what is to expect based on individual treatment regimes and individual responses to treatment.
