Chronic lymphocytic leukemia (CLL) is the
Small lymphocytic lymphoma (SLL) is another name for the same disease. “CLL” is used when most cancer cells are found in your blood and bone marrow. “SLL” is used when most cancer cells are in your lymph nodes.
In the United States, about
You can learn more about how CLL and SLL are treated.
CLL and SLL are slow-growing cancers that develop in white blood cells called lymphocytes. More specifically, they develop in abnormal
CLL and SLL are essentially the same diseases. Doctors choose a name based on where most cancer cells are found. Both conditions are
SLL is used when most cancer cells are found in the lymphatic area. Blood cells are produced inside your bones through the bone marrow.
A doctor will diagnose either CLL or SLL. Here is a look at how they compare.
|Where most cancer cells are found||Lymph nodes|
|Monoclonal lymphocyte cell count in blood||More than
||Less than 5,000/mm3|
SLL is classified as a type of
What causes CLL/SLL?
Researchers don’t exactly know why some people develop CLL or SLL. It’s thought that
Many different genetic mutations in the DNA of blood-producing cells have been identified in people with CLL or SLL. A loss of part of chromosome 13 is the most common genetic mutation that’s been identified.
Slow-growing cancer like CLL and SLL can lead to overproduction of B lymphocytes. Cancer cells are indistinguishable under a microscope, and the development of CLL and SLL is the same.
Usually, CLL represents the initial phase where cells are isolated to the blood and bone marrow. CLL
About Richter’s syndrome
CLL and SLL can also develop into an aggressive form of non-Hodgkin’s lymphoma called Richter’s syndrome. Richter’s syndrome develops in 3 to 15 percent of people with CLL or SLL.
The outlook for Richter’s syndrome is generally poor. Usual symptoms of Richter’s syndrome include:
- Increased swelling of the lysies.
- The swelling in the body.
- high temperature
- There is abdominal pain.
- More weight loss.
- The counts of the blood cell.

- Your blood cell count is important.
- Whether you have swelling in your body.

- Your symptoms are related to something.
- How you respond to treatment.
- Does cancer return after treatment?
Treatments for CLL and SLL can be found.
- watchful waiting
- Radiation therapy is done.
- The treatment is called Chemo.
- Targeted therapy.
- Stem cell transplant.
- clinical trials
Many people with CLL and SLL live with the condition for a long time. The outlook of the disease is unaffected by the distinction between CLL and SLL.
Half of the people with CLL or SLL live at least

Your doctor can give you an idea of what to expect. Statistics can give you an idea of your outlook, but there are many factors that can affect how you respond to treatment.
Factors that influence outlook
Factors that can affect your outlook are listed.
The type of blood cancer that is referred to as CLL and SLL is the same type of blood cancer that develops in a type of white blood cell called lymphocytes. Most cancer cells are in your blood or bone marrow, which is when CLL is used. SLL is used when most cancer cells are found in the lymph nodes.
