Leukemia of early cells of the lymphocyte series. Occurs more frequently in children
acute leukemia characterized by proliferation of immature lymphoblast-like cells in bone marrow, lymph nodes, spleen, and blood; most common in children
A form of leukemia characterized by replacement of normal bone marrow by immature (blast) cells of the blood-forming series. Eighty per cent of cases are in children less than 10 years of age. Cure rate is 65-75%.
Type of fast growing cancer of the lymphocytes, one of the white blood cells. AKA acute lymphocytic leukemia. Appears mostly in children, but can affect adults.
A rapidly progressive cancer that starts by the malignant transformation of a marrow lymphocyte. ALL is the most common form of childhood leukemia. The transformed, now malignant, cell multiplies and accumulates in the marrow as leukemic lymphoblasts. The lymphoblasts block normal blood cell-formation in the marrow, resulting in insufficient production of red cells, white cells and platelets. The specific chromosome and genic changes in the affected cells can be used to classify ALL. These findings can be used to determine the expected response of that type of ALL to treatment. The risk category of the ALL determined from the genic changes can affect the treatment applied. (See Society booklet "Acute Lymphocytic Leukemia")
An acute (sudden onset), rapidly progressing form of leukemia that is characterized by the presence in the blood and bone marrow of large numbers of unusually immature white blood cells destined to become lymphocytes. Acute lymphoblastic leukemia is also called acute lymphocytic leukemia and is abbreviated ALL (spoken not as the word "all", but as the three letters A-L-L). ALL is the most common cancer occurring in children, representing almost 25% of cancer among children. There is a sharp peak in the incidence of ALL incidence among children ages 2 to 3. This peak is approximately fourfold greater than that for infants and is nearly 10-fold greater than that for youths who are 19 years old. See the entire definition of Acute lymphoblastic leukemia
(...LIM-foh-BLAS-tik loo-KEE-mee-uh) ALL. A fast-growing type of leukemia (blood cancer) in which too many lymphoblasts (immature white blood cells) are found in the blood and bone marrow. Also called acute lymphocytic leukemia.
An acute form of leukemia occurring predominantly in children, characterized by the unrestrained production of immature lymphoblasts (a type of white cell) in the blood-forming tissues, particularly the bone marrow, spleen, and lymph nodes.
ALL. A quickly progressing disease in which too many immature white blood cells (called lymphoblasts) are found in the blood and bone marrow. Also called acute lymphocytic leukemia.
A fast growing cancer of the lymphocytes, one of the white blood cells. Also called acute lymphocytic leukemia. Appears most often in children, but can occur in adults.
A progressing disease in which too many immature white blood cells (lymphoblasts) are found in the blood and bone marrow. Synonym: ALL or acute lymphocytic leukemia.
Acute lymphoblastic leukemia (ALL), also known as acute lymphocytic leukemia, is a cancer of the white blood cells, characterised by the overproduction and continuous multiplication of malignant and immature white blood cells (referred to as lymphoblasts) in the bone marrow. It is a hematological malignancy. It is fatal if left untreated as ALL spreads into the bloodstream and other vital organs quickly.
