Acute lymphocytic leukemia - Highlights

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of leukemia.

Alternative Names

Acute lymphoblastic (or lymphocytic) leukemia

Highlights:

Acute Lymphocytic Leukemia (ALL)

There are four major types of leukemia. ALL is the most common type of leukemia diagnosed in children, and the least common type diagnosed in adults. About 5,200 people are diagnosed with ALL each year. Children account for two-thirds of these cases. In general, children with ALL have a better prognosis than adults. Most children with ALL can be cured of this cancer.

Symptoms and Diagnosis

Symptoms of ALL include fatigue, pale skin, recurrent infections, bone pain, bruising, and small red spots under the skin. Doctors use various tests, including blood counts and bone marrow biopsies, to diagnose ALL.

Treatment

ALL is treated with chemotherapy and, sometimes, radiation. Children receive different types of chemotherapy regimens than adults. Patients with advanced cancer that has not responded to these treatments may need a stem cell transplant.

Infection Prevention

Both chemotherapy and transplantation increase the risk for infection. Patients must take serious precautions to avoid exposure to germs. Ways to prevent infection include:

Practice good hygiene including regular handwashing and dental care (brushing, flossing)
Avoid crowds, especially during cold and flu season
Eat only well-cooked foods (no raw fruits or vegetables)
Boil tap water before drinking it
Do not keep fresh flowers or plants in your house as they may carry mold
Make sure you are up to date with vaccinations. Children may need to be reimmunized
