Learn About Acute Lymphoblastic Leukemia (ALL)

What is the definition of Acute Lymphoblastic Leukemia (ALL)?

Acute lymphoblastic leukemia (ALL) is a fast-growing cancer of a type of white blood cell called a lymphoblast.

ALL occurs when the bone marrow produces a large number of immature lymphoblasts. Bone marrow is the soft tissue in the center of bones that helps form all blood cells. The abnormal lymphoblasts grow quickly and replace normal cells in the bone marrow. ALL prevents healthy blood cells from being made. Life-threatening symptoms can occur as normal blood counts drop.

What are the alternative names for Acute Lymphoblastic Leukemia (ALL)?

ALL; Acute lymphoblastic leukemia; Acute lymphoid leukemia; Acute childhood leukemia; Cancer - acute childhood leukemia (ALL); Leukemia - acute childhood (ALL); Acute lymphocytic leukemia

What are the causes of Acute Lymphoblastic Leukemia (ALL)?

Most of the time, no clear cause can be found for ALL.

The following factors may play a role in the development of all types of leukemia:

  • Certain chromosome problems
  • Exposure to radiation, including x-rays before birth
  • Past treatment with chemotherapy drugs
  • Receiving a bone marrow transplant
  • Toxins, such as benzene

The following factors are known to increase the risk for ALL:

  • Down syndrome or other genetic disorders
  • A brother or sister with leukemia

This type of leukemia usually affects children ages 3 to 7. ALL is the most common childhood cancer, but it can also occur in adults.

What are the symptoms of Acute Lymphoblastic Leukemia (ALL)?

ALL makes a person more likely to bleed and develop infections. Symptoms include:

  • Bone and joint pain
  • Easy bruising and bleeding (such as bleeding gums, skin bleeding, nosebleeds, abnormal periods)
  • Feeling weak or tired
  • Fever
  • Loss of appetite and weight loss
  • Paleness
  • Pain or feeling of fullness below the ribs from an enlarged liver or spleen
  • Pinpoint red spots on the skin (petechiae)
  • Swollen lymph nodes in the neck, under arms, and groin
  • Night sweats

These symptoms can occur with other conditions. Talk to a health care provider about the meaning of specific symptoms.

What are the current treatments for Acute Lymphoblastic Leukemia (ALL)?

The first goal of treatment is to get blood counts back to normal. If this occurs and the bone marrow looks healthy under the microscope, the cancer is said to be in remission.

Chemotherapy is the first treatment tried with the goal of achieving a remission.

  • The person may need to stay in the hospital for chemotherapy. Or it can be given at a clinic and the person goes home afterward.
  • Chemotherapy is given into the veins (by IV) and sometimes into the fluid around the brain (the spinal fluid).

After a remission is achieved, more treatment is given to achieve a cure. This treatment can include more IV chemotherapy or radiation to the brain. Stem cell or, bone marrow, transplant from another person may also be done. Further treatment depends on:

  • Age and health of the person
  • Genetic changes in the leukemia cells
  • How many courses of chemotherapy it took to achieve remission
  • If abnormal cells are still detected under the microscope
  • Availability of donors for stem cell transplant

You and your provider may need to manage other concerns during your leukemia treatment, including:

  • Having chemotherapy at home
  • Managing your pets during chemotherapy
  • Bleeding problems
  • Dry mouth
  • Eating enough calories
  • Safe eating during cancer treatment
