How Does ALL Develop?ALL results from either an acquired or a genetic injury to the DNA (genetic material) of a developing stem cell in the bone marrow.
This damaged cell becomes a leukemic cell and multiplies uncontrollably into billions of cells called leukemic lymphoblasts.
As a result, the number of healthy blood cells (red cells, white cells and platelets) is usually lower than normal.
Risk FactorsDoctors don't know why some cells become leukemic cells and others don't. Usually DNA mutations associated with ALL occur during a person's lifetime rather than being inherited from a parent. For most people who have acute lymphoblastic leukemia (ALL), there are no obvious reasons why they developed the disease. Risk factors associated with the disease include:
Currently, there's no way to prevent the disease. You can't catch ALL from someone else. Source: Acute Lymphoblastic Leukemia (ALL) in Adults. Reviewed by Ryan D.

A decrease inthe number of white blood cells is termedleukopenia. Granulocytosis is an increase in the number ofgranulocytes (neutrophils, eosinophils, basophils) in the blood. The neutrophil is the most numerous of thegranulocytes, and the termgranulocytosisis often used in place of neutrophilia.

Get answer to your question and much more Is BFirst, patients with T-cell ALL are generally older than those with B-cell ALL and, therefore, have poorer tolerance to chemotherapy, especially dexamethasone and asparaginase, and have increased risk of extramedullary relapse.
What are the two types of acute lymphocytic leukemia?Acute lymphocytic leukemia (ALL) can be characterized into different sub-types:. Philadelphia chromosome-positive ALL.. Philadelphia chromosome-negative ALL.. B cell ALL.. T cell ALL.. How do you distinguish B ALL and TSimilar to B-ALL, the key prognostic determinant in T-ALL is minimal residual disease (MRD) response. Unlike B-ALL, other factors including age, white blood cell count at diagnosis, and genetics of the ALL blasts are not independently prognostic when MRD response is included.
What are the stages of acute lymphoblastic leukemia?The phases of ALL:. Untreated ALL.. ALL in remission (after treatment, you have no signs or symptoms of leukemia). Minimal residual disease (ALL appears to be in remission, but tests find a few leukemia cells in your bone marrow). Refractory ALL (the leukemia is not responding to treatment). |
