Acute Lymphocytic Leukemia

7 March 2017

Acute lymphocytic leukemia (ALL), also called acute lymphoblastic leukemia, is a cancer that starts from the early version of white blood cells called lymphocytes in the bone marrow.

Leukemia cells usually invade the blood fairly quickly. They can then spread to other parts of the body, including the lymph nodes, liver, spleen, central nervous system and testicles. Other types of cancer can start in these organs and spread to the bone marrow, but these are not leukemia.

The term acute means that the leukemia can progress quickly, if not treated it would probably be fatal within a few months.

Lymphocytic means it develops from immature forms of lympocytes, a type of white blood cell. This is different from acute myeloid leukemia.

There are many types of leukemia, these differ based on the types of cells they start in, how quickly they grow, which people they affect and how they are treated.

In acute leukemia the bone marrow cells cannot mature properly. Immature leukemia cells continue to reproduce and build up. Some types of acute leukemia respond well to treatment and many patients can be cured. Other types have a less favourable outlook.

There are only a few known risk factors for ALL. 

Radiation exposure

Certain chemical exposures

Certain viral infections

Inherited syndromes

Race/ethnicity

Gender

Having an identical twin with ALL

Some people with ALL have one or more of the known risk factors, but most do not. The cause of their cancer remains unknown at this time.

Most people who get ALL have no known risk factors, so there is no way to prevent leukemia from developing.

There are no special tests that detect ALL early. The best way is to report any possible signs or symptoms to the doctor straightaway.

ALL can cause many different signs and symptoms.

  • Feeling tired
  • Feeling weak
  • Feeling dizzy or lightheaded
  • Shortness of breath
  • Fever
  • Infections that don't go away or keep coming back
  • Bruising easily
  • Bleeding (frequent or severe nosebleeds and bleeding gums)
  • Weight loss
  • Fever
  • Night sweats
  • Fatigue
  • Loss of appetite
  • Swelling in the abdomen
  • Enlarged lymph nodes
  • Bone or joint pain

Of course, these are not just symptoms of ALL and are more often caused than something other than leukemia.

Tests will be carried out to confirm the diagnosis. Doctors study the patient's medical history and perform a phycical exam, other tests include blood test, bone marrow test, chromosome testing, lumbar puncture, lymph node biopsy, imaging tests, x-ray, CT scan, MRI scan, ultrasound, Gallium and bone scan.

Treatment options for each patient are based on the leukemia subtype as well as certain prognostic fewatures.

The main types of treatment used for ALL are:

  • Chemotherapy
  • Targeted therapy
  • Stem cell transplant

Other treatments may include:

  • Surgery
  • Radiation therapy
  • Monoclonal antibodies

Treatment typically lasts about 2 years, and needs to start very soon after it is diagnosed.
