Dictionary

Dictionary

acute lymphoblastic leukemia (ALL)

A fast-growing cancer that causes too many immature white

blood cells called lymphoblasts to be made.

adolescents and young adults (AYAs)

Patients who are 15 to 39 years of age.

allogeneic stem cell transplant (SCT)

A treatment in which the patient receives immature blood-

forming cells (blood stem cells) from another person to

replace damaged or diseased cells in the bone marrow.

anesthesia

Loss of feeling with or without loss of wakefulness caused

by drugs.

anthracycline

A cancer drug that damages and disrupts the making of

DNA in cells.

B-cell

One of two main types of white blood cells called

lymphocytes that help protect the body from infection and

disease. Also called B-lymphocyte.

B-cell ALL

A fast-growing (acute) blood cancer (leukemia) that starts in

a B-lymphoblast—an immature cell that normally becomes a

mature white blood cell called a B-cell or B-lymphocyte.

BCR-ABL

fusion gene

An abnormal set of coded instructions for controlling cells

that is formed when the

BCR

gene and

ABL

gene join (fuse)

together on the Philadelphia chromosome.

BCR-ABL protein

An abnormal protein that is made by the

BCR-ABL

fusion

gene and causes too many abnormal white blood cells

(leukemia cells) to be made.

biopsy

Removal of small amounts of tissue from the body to be

tested for disease.

blast cell

An immature blood cell.

blood cell count

The number of blood cells in a sample of blood.

blood chemistry profile

A test that measures the amount of chemicals in the blood

to look for signs of disease and check how well organs are

working.

blood stem cell

An immature cell from which all other types of blood cells

are made.

bloodstream

Blood that flows throughout the body in small tubes called

blood vessels.

B-lymphocyte

One of two main types of white blood cells called

lymphocytes that help protect the body from infection and

disease.

bone marrow

The soft, sponge-like tissue in the center of most bones

where blood cells are made.

bone marrow aspiration

The removal of a small amount of liquid bone marrow (soft

tissue in the center of most bones where blood cells are

made) to test for disease.

bone marrow biopsy

The removal of a small amount of solid bone and bone

marrow (the soft tissue in the center of most bones where

blood cells are made) to test for disease.

cell assessment

Use of a microscope and special dyes to examine the

physical features of cells in a sample of blood or tissue

removed from your body. Also called morphologic

assessment.

cell subtype

Smaller groups that leukemia cells are classified into based

on the specific type of lymphocyte affected.

central nervous system (CNS)

The brain and the spinal cord—the bundle of nerves that

runs from the base of the skull down the back.

central nervous system (CNS) disease

Leukemia cells in the fluid around the brain and spinal cord,

which make up the central nervous system.
