Hairy Cell Leukemia (HCL) Overview
Learn About Hairy Cell Leukemia (HCL)
View Main Condition: Leukemia
Hairy cell leukemia (HCL) is an unusual cancer of the blood. It affects B lymphocyte cells, a type of white blood cell.
Leukemic reticuloendotheliosis; HCL; Leukemia - hairy cell
HCL is caused by the abnormal growth of certain B cells. The cells look "hairy" under the microscope because they have fine projections extending from their surface.
HCL usually leads to a low number of normal blood cells.
The cause of this disease is unknown. Certain genetic changes in the cancer cells may be the cause. It affects men more often than women. The average age of diagnosis is 55.
Symptoms of HCL may include any of the following:
- Easy bruising or bleeding
- Heavy sweating (especially at night)
- Fatigue and weakness
- Feeling full after eating only a small amount
- Recurrent infections and fevers
- Pain or fullness in the upper left belly (enlarged spleen)
- Swollen lymph glands
- Weight loss
Treatment may not be needed for the early stages of this disease. Some people may need an occasional blood transfusion.
If treatment is needed because of very low blood counts, chemotherapy medicines can be used.
In most cases, chemotherapy can relieve the symptoms for many years. When the signs and symptoms go away, you are said to be in remission.
Removing the spleen may improve blood counts, but is unlikely to cure the disease. Antibiotics can be used to treat infections. People with low blood counts may receive growth factors and, possibly, transfusions.

The low blood counts caused by hairy cell leukemia can lead to:
- Infections
- Fatigue
- Excessive bleeding
Contact your provider if you have major bleeding. Also contact your provider if you have signs of infection, such as a persistent fever, cough, or general ill feeling.
There is no known way to prevent this disease.
Summary: This is a national multi-centre, experimental, cross-sectional, non-profit study.
Summary: The goal of this clinical research study is to learn if cladribine given in combination with low-dose cytarabine (LDAC) and decitabine can help control the disease in patients with AML or MDS. The safety of this drug combination will also be studied. Cladribine is designed to interfere with the cell's ability to process DNA (the genetic material of cells). It can also insert itself into the DNA of...
