Diagnosis

Blood tests

Tests and procedures used to diagnose chronic lymphocytic leukemia include blood tests designed to:

  • Count the number of cells in a blood sample. A complete blood count may be used to count the number of lymphocytes in a blood sample. A high number of B cells, one type of lymphocyte, may indicate chronic lymphocytic leukemia.
  • Determine the type of lymphocytes involved. A test called flow cytometry or immunophenotyping helps determine whether an increased number of lymphocytes is due to chronic lymphocytic leukemia, a different blood disorder or your body's reaction to another process, such as infection.

    If chronic lymphocytic leukemia is present, flow cytometry may also help analyze the leukemia cells for characteristics that help predict how aggressive the cells are.

  • Analyze lymphocytes for genetic abnormalities. A test called fluorescence in situ hybridization (FISH) examines the chromosomes inside the abnormal lymphocytes to look for abnormalities. Doctors sometimes use this information to determine your prognosis and help choose a treatment.

Other tests

In some cases, your doctor may order additional tests and procedures to aid in diagnosis, such as:

  • Tests of your leukemia cells that look for characteristics that could affect your prognosis
  • Bone marrow biopsy and aspiration
  • Imaging tests, such as computerized tomography (CT)

Staging

Once a diagnosis is confirmed, your doctor determines the extent (stage) of your chronic lymphocytic leukemia. Two different staging systems are used. Each assigns a stage — early, intermediate or advanced — that indicates the progression of a person's chronic lymphocytic leukemia. These levels are used to determine treatment options.

In general, people with early-stage disease don't require immediate treatment. Those with intermediate-stage disease and advanced-stage disease may be given the option to begin treatment right away.

Treatment

Your treatment options for chronic lymphocytic leukemia depend on several factors, such as the stage of your cancer, whether you're experiencing signs and symptoms, your overall health, and your preferences.

Treatment may not be necessary in early stages

People with early-stage chronic lymphocytic leukemia typically don't receive treatment, though clinical trials are evaluating whether early treatment may be helpful. Studies have shown that early treatment doesn't extend lives for people with early-stage chronic lymphocytic leukemia.

Rather than put you through the potential side effects and complications of treatment before you need it, doctors carefully monitor your condition and reserve treatment for when your leukemia progresses. Doctors call this watchful waiting.

Your doctor will plan a checkup schedule for you. You may meet with your doctor and have your blood tested every few months to monitor your condition.

Treatments for intermediate and advanced stages

If your doctor determines your chronic lymphocytic leukemia is progressing or is in the intermediate or advanced stages, your treatment options may include:

  • Chemotherapy. Chemotherapy is a drug treatment that kills cancer cells. Chemotherapy treatments can be administered through a vein or taken in pill form. Depending on your situation, your doctor may use a single chemotherapy drug or you may receive a combination of drugs.
  • Targeted drug therapy. Targeted drugs are designed to take advantage of the specific vulnerabilities of your cancer cells. Targeted therapy drugs used in treating chronic lymphocytic leukemia include alemtuzumab (Campath), ibrutinib (Imbruvica), idelalisib (Zydelig), lenalidomide (Revlimid), obinutuzumab (Gazyva), ofatumumab (Arzerra) and rituximab (Rituxan).

    Other targeted therapies are being studied in clinical trials.

  • Bone marrow stem cell transplant. Bone marrow stem cell transplants use strong chemotherapy drugs to kill the stem cells in your bone marrow that are creating diseased lymphocytes. Then healthy adult blood stem cells from a donor are infused into your blood, where they travel to your bone marrow and begin making healthy blood cells.

    A reduced intensity, or "mini," bone marrow stem cell transplant is similar to a standard stem cell transplant, but it uses lower doses of chemotherapy drugs.

    Bone marrow stem cells may be a treatment option in certain cases when other treatments haven't worked or for certain cases of very aggressive forms of chronic lymphocytic leukemia.

Supportive care

Your doctor will meet with you regularly to monitor any complications you may experience. Supportive care measures may help prevent or relieve any signs or symptoms. Supportive care may include:

  • Cancer screening. Your doctor will evaluate your risk of other types of cancer and may recommend screening to look for signs of other cancers. For instance, your doctor may recommend an annual skin examination to look for signs of skin cancer.
  • Vaccinations to prevent infections. Your doctor may recommend certain vaccinations to reduce your risk of infections, such as pneumonia and influenza.
  • Monitoring for other health problems. Your doctor may recommend regular checkups to monitor your health during and after treatment for chronic lymphocytic leukemia.
  • Palliative care. Palliative care is specialized medical care that focuses on providing relief from pain and other symptoms of a serious illness. Palliative care specialists work with you, your family and your other doctors to provide an extra layer of support that complements your ongoing care. When palliative care is used along with all of the other appropriate treatments, people with cancer may feel better and live longer.

Clinical trials

Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease.

Alternative medicine

No alternative treatments have been proved to cure chronic lymphocytic leukemia.

Alternative treatments for coping with fatigue

Some alternative medicine therapies may help you cope with fatigue, which is commonly experienced by people with chronic lymphocytic leukemia. Your doctor can treat fatigue by controlling the underlying causes, but often medications alone aren't enough. You may find relief through alternative therapies, such as:

  • Exercise
  • Massage
  • Meditation
  • Relaxation techniques
  • Yoga

Talk to your doctor about your options. Together you can devise a plan to help you cope with fatigue.

Green tea extracts for people with early-stage leukemia

A green tea extract has shown some promise in initial clinical trials for treating chronic lymphocytic leukemia. Laboratory research determined that a compound in green tea extract, called EGCG, can kill chronic lymphocytic leukemia cells.

In a study of people with early-stage chronic lymphocytic leukemia, taking EGCG in pill form reduced some signs of the disease in a portion of the participants. For instance, some participants noticed that their enlarged lymph nodes decreased in size, and blood tests revealed some participants had fewer leukemia cells in their blood. Research into EGCG and green tea is ongoing.

Coping and support

Chronic lymphocytic leukemia is typically a slow-growing cancer that may not require treatment. While some people may refer to this as a "good" type of cancer, it doesn't really make receiving a cancer diagnosis any easier. While you may initially be shocked and anxious about your diagnosis, you'll eventually find your own way of coping with chronic lymphocytic leukemia. Until then, try to:

  • Find out enough about your cancer to make decisions about your care. Write down questions to ask your doctor before each appointment and look for information in your local library and on the Internet. Good sources include the National Cancer Institute, the American Cancer Society, and the Leukemia & Lymphoma Society.
  • Turn to family and friends for support. Stay connected to family and friends for support. It can be tough to talk about your diagnosis, and you'll likely get a range of reactions when you share the news. But talking about your diagnosis and passing along information about your cancer can help. So can the offers of help that often result.
  • Connect with other cancer survivors. Consider joining a support group, either in your community or on the Internet. A support group of people with the same diagnosis can be a source of useful information, practical tips and encouragement.
  • Explore ways to cope with the nagging, chronic nature of the disease. If you have chronic lymphocytic leukemia, you'll likely face ongoing tests and ongoing worries about your white blood cell count. Try to find some activities that help you relax, whether it's yoga, exercise or gardening. Talk to a counselor, therapist or social worker if you need help dealing with the emotional challenge of this chronic disease.

Preparing for your appointment

If you have any signs or symptoms that worry you, start by making an appointment with your family doctor. If your doctor determines you may have chronic lymphocytic leukemia, you may be referred to a doctor who specializes in diseases of the blood and bone marrow (hematologist).

Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well-prepared. Here's some information to help you get ready and know what to expect from your doctor.

What you can do

  • Be aware of any pre-appointment restrictions. At the time you make the appointment, ask if there's anything you need to do in advance, such as restrict your diet.
  • Write down key personal information, including any major stresses or recent life changes.
  • Make a list of all medications, vitamins or supplements that you're taking.
  • Take a family member or friend along. Sometimes it can be difficult to remember all the information provided during an appointment. Someone who accompanies you may recall something that you missed or forgot.
  • Write down questions to ask your doctor.

Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For chronic lymphocytic leukemia, some basic questions include:

  • What do my test results mean?
  • Do I need treatment right away?
  • If I don't begin treatment right now, will that limit my treatment options in the future?
  • Should I undergo additional tests?
  • What are my treatment options?
  • What are the side effects associated with each treatment?
  • Is there one treatment that's strongly recommended for someone with my diagnosis?
  • How will treatment affect my daily life?
  • I have these other health conditions. How can I best manage them together?
  • Are there any brochures or other printed material that I can take with me? What websites do you recommend?

In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions as they occur to you during your appointment.

What to expect from your doctor

Your doctor is likely to ask you a number of questions. Being ready to answer them may allow time to cover other points you want to address. Your doctor may ask:

  • When did you first begin experiencing symptoms?
  • Have your symptoms been continuous or occasional?
  • How severe are your symptoms?
  • What, if anything, seems to improve your symptoms?
  • What, if anything, appears to worsen your symptoms?
