Chronic lymphocytic leukemia (CLL) is a type of cancer affecting a type of white blood cell in the blood and bone marrow. It often progresses slowly and is diagnosed most often during routine blood testing.
Understanding the stages of CLL—from stage 0 to 4—can help you navigate a CLL diagnosis. Although each increase in stage represents disease progression, you have treatment options and ways to manage symptoms to help provide a good quality of life.
This article will describe each stage's prognosis, symptoms, and treatment options.

Beginning to End Stages of CLLOnce diagnosed, chronic lymphocytic leukemia is staged to determine how advanced the disease is and to help determine the best treatment. The most common staging system in the United States is the Rai system.
The Rai staging system defines stages from stage 0 to stage 4 based on factors including:
The stages of the Rai system are also described in three groups to classify risk. Stage 0 is considered low risk, stages 1 and 2 are intermediate risk, and stages 3 and 4 are regarded as high risk.
The Binet system is used more frequently in Europe. It categorizes CLL into three stages (A, B, and C) depending on the number of affected lymph tissue groups and the presence of anemia or low platelets.
In addition to the staging systems mentioned here, there is also the CLL International Prognostic Index (CLL-IPI), which considers genetic factors of an individual's CLL in addition to blood and imaging tests.
Stage 0Stage 0 is the earliest and most low-risk CLL stage. It is identified by an increased number of lymphocytes in the blood, but there are no other symptoms or signs of disease. Most people diagnosed with CLL will be diagnosed at stage 0. It is often found incidentally during routine blood tests.
Stage 1In stage 1 CLL, in addition to the increased lymphocytes in the blood, there are also enlarged lymph nodes present. Red blood cells and platelets are at normal or near normal levels.
Stage 2For stage 2 CLL, in addition to high lymphocyte levels in the blood, the liver or spleen is enlarged. Lymph nodes may or may not be enlarged as well. Red blood cell and platelet levels are at normal or near normal levels.
Stage 3In stage 3 CLL, progression of the disease is noted with a high level of lymphocytes and anemia (a low number of healthy red blood cells). In addition to the changes in the blood levels, the lymph nodes, the spleen, or the liver may become enlarged.
Stage 4Stage 4 CLL is the most advanced stage of the disease. It is indicated by a high lymphocyte count, anemia, and a low platelet count. There may or may not be enlargement of the lymph nodes, spleen, or liver.
How CLL Staging Affects PrognosisThe staging of CLL is an important factor in determining the prognosis and treatment strategies. Early stages, such as stage 0 and stage 1, often have a good prognosis, with many living for years without needing treatment, as the disease typically follows a slow growth pattern.
As CLL advances into further stages, it becomes more aggressive and may have a poorer prognosis. However, advancements in research and treatments have improved the outlook for CLL. The five-year relative survival for CLL in 1975 was 65.1%, but increased to 87.2% by 2021.
Progressive CLL Symptoms From Stage to StageEach individual living with CLL may have various symptoms associated with their disease. At an early stage, there may be no disease symptoms at all.
As CLL progresses, more symptoms may appear as the change in blood cell levels and organ and lymph node enlargement develop. The development of these symptoms can indicate active disease and may mean that treatment is necessary.
Symptoms from CLL can include:
Abdominal pain or swelling
Bleeding or bruising
Chills
Fevers
Night sweats
Significant fatigue
Unintentional weight loss
Treatment for CLL depends on the stage and other prognostic factors. Different treatment options are available for each stage. The exact treatment will be decided upon in consultation with an oncologist (cancer specialist).
Stage 0In stage 0 CLL, treatment isn't usually required. The primary medical approach is watchful waiting. During the watchful waiting period, blood work and physical exams are done routinely, often every three months, to evaluate blood levels and assess for the development of any symptoms.
Stage 1Stage 1 CLL is still an early stage. If you are not experiencing any symptoms, no treatment is required. Watchful waiting may still be all that is needed. If there are symptoms present, treatment may be started. Treatment options are listed in the section below.
Stages 2 to 4As CLL progresses and treatment is required, many treatment options are available. Treatments may be individualized and based on the presence or absence of genetic mutations in the CLL. Treatments may be used alone or in various combinations.
Treatment options include:
Targeted therapy
Immunotherapy
Chemotherapy
Radiation therapy
Stem cell transplant
Clinical trial
Targeted Therapy
Medications that target specific chemical pathways that impact CLL growth can be used to provide more precise treatment. These medications tend to have fewer side effects than chemotherapy (which affects all actively dividing cells).
Examples of these medications are Bruton tyrosine kinase (BTK) inhibitors like Calquence (acalabrutinib) and Imbruvica (ibrutinib), and antiapoptotic protein B cell lymphoma 2 (BCL2) inhibitors like Venclexta (venetoclax).
Immunotherapy
Immunotherapy uses the body's immune system to help fight CLL. Some types of immunotherapy are monoclonal antibodies, manufactured immune proteins that bind to certain proteins on the outside of the cancer cells, marking them for destruction by the immune system.
Examples of immunotherapy are Rituxan (rituximab), Gazyva (obinutuzumab), and Arzerra (ofatumumab).
Chemotherapy
Chemotherapy medications kill rapidly dividing cells. Unfortunately, chemotherapy can't tell the difference between a healthy cell and a cancer cell, so healthy cells are affected as well as unhealthy ones.
Common chemotherapy medications for CLL are Fludara (fludarabine), Cytoxan (cyclophosphamide), and Treanda (bendamustine). These may be given in combination with other treatments.
Radiation Therapy
Radiation therapy uses high-energy beams to kill cancer cells. Radiation is most often used when a small group of lymph nodes are enlarged and causing symptoms, such as pain.
Stem Cell Transplant
During a stem cell transplant, large doses of chemotherapy and possibly radiation are given to wipe out the bone marrow and cancer cells. Healthy stem cells harvested from the person (before chemo or radiation) or a donor are then infused to reestablish blood cell production.
Clinical Trial
Clinical trials may be an option for treatment. These are studies to evaluate new treatments and combinations of therapies.
CLL Testing and Follow-Up AppointmentsRoutine testing and follow-up appointments are needed to check for disease progression and evaluate how well treatment is working.
Initially, testing to determine the diagnosis and disease stage include:
Complete blood count (CBC) and differential: A blood test that measures and assesses blood cells
Flow cytometry: A lab technique performed on blood and other tissues to differentiate cells by their properties
Bone marrow biopsy: A procedure to obtain a sample of bone marrow (often from the hip) to assess in the lab
Imaging studies like computed tomography (CT) scans may be used to see if lymph nodes or organs are enlarged.
In routine follow-ups, blood tests and imaging may assess the progression of CLL. These visits also provide a place for discussing symptoms and receiving needed support. Keeping up with these appointments and maintaining regular communication with their oncology team empowers the person to manage CLL actively.
SummaryChronic lymphocytic leukemia is a slow-growing cancer of the blood and bone marrow. Understanding the stages of CLL, from 0 to 4, helps determine the best treatment options.
The Rai staging system, commonly used in the United States, categorizes CLL into low, intermediate, and high risk based on factors like lymphocyte count and organ enlargement.
Early stages (0 and 1) typically have a good prognosis, with many people not requiring immediate treatment. Advanced stages (3 and 4) may need more active treatment.
Regular testing and follow-up appointments are important for monitoring disease progression and treatment effectiveness.

What Is The Outlook For Chronic Lymphocytic Leukemia?
The 5-year relative survival rate for chronic lymphocytic leukemia (CLL) among adults ages 20 or older is 87%. Although the condition is typically incurable, a person can live with this form of leukemia for many years.
There are two types of chronic lymphocytic leukemia (CLL). The cells for each form are slightly different, but doctors can only tell them apart by testing them in a laboratory.
Slower-growing CLL occurs when there are too many lymphocytes. A person may not need treatment for some time.
Faster-growing CLL occurs when there are too many CLL cells in the blood, blocking typical cell production. It is typically more severe.
This article focuses on survival rates for CLL and the factors that can influence a person's life expectancy or outlook. It also discusses how to achieve an optimal quality of life with CLL.
Survival rates can give a person more information about the outlook for their condition and help them plan treatment and care. However, survival rates are only an estimate.
Survival rates for leukemia have improved significantly over the past 40 years. In the United States, the current 5-year relative survival rate for CLL in adults ages 20 years or older is 87%.
CLL accounts for around 38% of new leukemia cases in adults ages 20 years or older.
The stage of CLL is an important factor in life expectancy. However, other factors also have an effect.
Doctors talk about stages to indicate how far cancer has progressed in a person's body. However, as leukemia affects the blood, doctors cannot stage it in this way.
There are two systems for staging leukemia: the Rai system and the Binet system. In the United States, doctors more commonly use the Rai system, while the Binet system is more common in Europe.
In the Rai system, a person undergoes blood tests to check for cancer cells and determine the number of white blood cells (WBC) in the blood and bone marrow.
Alongside a physical exam, this information can indicate one of five stages for CLL:
A higher stage number means that CLL is impacting more of the body. A higher stage will often shorten a person's life expectancy.
Learn about how CLL symptoms can progress.
Other factorsOther factors that can affect survival rates include:
Treatment can help people manage CLL symptoms and improve their overall outlook. It also focuses on stopping or slowing down the spread of CLL.
Treatment options for CLL include:
After treatment, a person may experience periods of few or no symptoms of CLL. This is often known as remission.
Learn more about CLL treatments.
Although there is no cure for CLL, ongoing treatment may help a person live with the condition for a long time. There are several ways that someone who has CLL can support their health and well-being.
Follow-up careAttending all medical appointments is essential to managing any medication and treatment side effects. When a doctor examines an individual at regular appointments, they can check for signs that CLL may be returning and treat it as quickly as possible.
Lifestyle changesPeople with CLL may benefit from gentle exercise and following a balanced diet. No research confirms a direct link between exercise, diet, and CLL management, but they can help support their overall health.
SupportGetting emotional support and expressing feelings may help an individual with CLL. This may be from friends, family, or community groups.
In the United States, the American Cancer Society offers information on local support groups and information services.
Having correct information can give a person more control and understanding. Finding out as much as possible about CLL and asking a doctor any questions can help with decisions about treatment and care.
Below are answers to common questions about CLL.
Can a person live a full life with CLL?Some people live for many years after a CLL diagnosis. Receiving an accurate diagnosis and beginning treatment as early as possible may help improve a person's outlook.
Learn about how doctors diagnose CLL.
How will CLL affect quality of life?In the early stages, CLL may not significantly affect a person's quality of life. However, a 2023 study of people with CLL in Israel found that males had a better quality of life during active surveillance, while females reported a better quality of life during active treatment. Symptoms of CLL and treatments may affect each person differently.
Is CLL classed as terminal?Although CLL is not curable, the 5-year relative survival rate for CLL is around 87% for adults ages 20 or older. A person's doctor can provide them with more accurate information about their outlook according to their individual circumstances.
Doctors can very rarely cure CLL. However, survival rates for this cancer are generally positive, particularly with early diagnosis and treatment. Currently, around 87% of people ages 20 or older with CLL survive for at least 5 years following diagnosis.
Various treatments can help manage symptoms and slow the progression of the condition. A person can also ask their doctor about support that may be available to them.

Stage 4 Breast Cancer Survival Rates And Life Expectancy
Life expectancy for stage 4 breast cancer can vary. Breast cancer that's spread to the lungs, for example, has a five-year survival rate of 10.94%. Other factors that affect life expectancy include age, cancer subtype, tumor size, and treatments.
Stage 4 breast cancer refers to the spread of breast cancer outside the breasts and surrounding lymph nodes. The most common sites of spread include the bones, lungs, liver, and brain. Breast cancer doesn't become bone or lung cancer if it spreads to these body parts. It's still breast cancer.
Stage 4 breast cancer, or metastatic breast cancer, is the most severe and life-threatening type. There's no cure, but treatment can improve survival rates. Read on to learn how long you can live with breast cancer that has metastasized.
There's no cure for stage 4 breast cancer. The main objective of metastatic cancer treatment is instead to extend survival time while opting for therapies with the fewest side effects. The reason is to ensure the best and longest quality of life possible. Some people can respond to treatment for many years or even decades. Others who have a very aggressive form of the disease may have a survival time of less than one year. The five-year survival rate for women with metastatic breast cancer is 29%. Several factors can affect your life expectancy with stage 4 breast cancer, including: Age Hormone receptors and HER2 receptors on cancer cells Locations the cancer has affected Overall health Tumor size People are living longer with stage 4 breast cancer. The number of females living with metastatic breast cancer in the United States is not only increasing. People with the disease are living longer, especially younger adults. Research has found that 11% of women younger than 64 who were diagnosed with stage 4 breast cancer between 2000 and 2004 lived for 10 years or more. Your survival rate with stage 4 breast cancer depends on many variables. You can't control certain variables, such as age and cancer subtype. A healthcare provider can help you control others, like treatment, to improve your survival rate. Age Age can impact survival rates in different ways. People younger than 40 are more likely to have more aggressive types of breast cancer than others. Adults aged 79 and older also have poorer health outcomes than younger adults. Research has shown that the five-year survival rates for the following age groups are: Younger than 40: 42.1% Aged 41 to 60: 32.8% Aged 61 to 80: 28.3% Older than 80: 11.8% Location Metastatic breast cancer is most likely to affect the bones, brain, liver, and lungs. The survival rate can depend on where the cancer cells have spread to: Bone: 39.8% Brain: 1.51% Liver: 7.34% Lungs: 10.94% Cancer Subtype, Tumor Size, and Treatment The type of breast cancer you have can impact life expectancy. About 15% to 20% of people have one type of breast cancer, called HER2-positive, in which the cancer cells produce high levels of HER2. This protein causes tumors to grow rapidly. The five-year survival rates for the following HER2-positive and HER2-negative breast cancers include: HR+/HER2+: 45.6% HR-/HER2+: 39.5% HR+/HER2-: 34% HR-/HER2-: 12.8% Tumor size can also affect survival rates. The survival rate for a primary tumor of 4.8 centimeters (cm) or less is 50%. This rate decreases to 25% for a primary tumor of more than 4.8 cm. Every stage 4 breast cancer diagnosis is different, so the methods used to treat it will also differ. Stage 4 breast cancer is usually treated systemically since the cancer has already spread to other areas of the body. Systemic treatments target the whole body and usually include hormone therapy, chemotherapy, targeted therapy, and immunotherapy. Research has shown that the type of treatment can impact survival rates. Those who receive systemic therapies have a three-year survival rate of 67.9%. Performance Status Performance status (PS) measures how well you can function with breast cancer. PS ranges from a score of 0 to 100. The higher the PS score, the more able you are to take care of yourself. Some evidence suggests that PS can impact life expectancy. The better you can function on your own, the more you may be responding to treatments. The following PS scores are linked to a median survival of: 80 to 100: 221 days 60 to 70: 115 days 40 to 50: 51 days 10 to 30: 22 days It can be difficult to cope with stage 4 breast cancer. You might feel strong anger, denial, and fear. Research has shown that people with metastatic breast cancer often develop anxiety and depression. Having a support system, including family and friends, might improve outcomes. Some evidence suggests that palliative care can prolong life expectancy. The goal of palliative care is to improve the quality of life. Palliative care helps manage symptoms and supports emotional and social health. Newer technologies are also increasingly being used in addition to more standard systemic treatment options. These treatments include ones that sequence the DNA of cancer cells for more specified treatments. Clinical trials are also designed to offer more options and possibly better outcomes to those with stage 4 breast cancer. Stage 4 breast cancer means cancer cells have spread outside the breasts. Life expectancy for stage 4 breast cancer depends on several variables, including age, location, cancer subtype, tumor size, and treatments. Lung metastases, for example, have a five-year survival rate of nearly 11%. A healthcare provider can work with you to determine what treatments best improve your life expectancy. They may recommend building a support group or considering palliative care. These options can help you cope with stage 4 breast cancer.Thanks for your feedback!
