Survival Statistics

How Many People Survive 5 Years Or More after Being Diagnosed with Chronic Lymphocytic Leukemia?

Relative survival is an estimate of the percentage of patients who would be expected to survive the effects of their cancer. It excludes the risk of dying from other causes. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.

In 2023, it is estimated that there will be 18,740 new cases of chronic lymphocytic leukemia and an estimated 4,490 people will die of this disease.

Who Gets This Cancer?

Chronic lymphocytic leukemia is more common in adults and more common among men than women, particularly white men. The rate of new cases of chronic lymphocytic leukemia was 4.6 per 100,000 men and women per year based on 2016–2020 cases, age-adjusted.

Who Dies From This Cancer?

Death rates from chronic lymphocytic leukemia are higher among older adults, or those 75 and older. People with leukemia have many treatment options, and treatment for leukemia can often control the disease and its symptoms. The death rate was 1.1 per 100,000 men and women per year based on 2016–2020 deaths, age-adjusted.

Trends in Rates

Changes Over Time

Keeping track of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.

Using statistical models for analysis, age-adjusted rates for new chronic lymphocytic leukemia cases have been falling on average 1.9% each year over 2010–2019. Age-adjusted death rates have been falling on average 2.9% each year over 2011–2020. 5-year relative survival trends are shown below.

More About This Cancer

Cancer and the Blood

Figure: Blood Cells Maturing from Stem Cells

Figure: Stem cells maturing into one of three types of mature blood cells: red blood cells, platelets, and white blood cells. Precursor cells are also shown: stem cells, myeloid blasts, lymphoid stem cells, and lymphoid blasts.

Leukemia is cancer that starts in the tissue that forms blood. Most blood cells develop from cells in the bone marrow called stem cells. In a person with leukemia, the bone marrow makes abnormal white blood cells. The abnormal cells are leukemia cells. Unlike normal blood cells, leukemia cells don't die when they should. They may crowd out normal white blood cells, red blood cells, and platelets. This makes it hard for normal blood cells to do their work. The four main types of leukemia are:

There is no standard staging system for leukemia. The disease is described as untreated, in remission, or recurrent.

The statistics presented in these stat facts are based on the most recent data available, most of which can be found in SEER*Explorer. In some cases, different year spans may be used.

Estimates of new cases and deaths for 2023 are projections made by the American Cancer Society (ACS), based on earlier reported data.

Cancer is a complex topic. There is a wide range of information available. These stat facts do not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although links are provided to information in many of these areas.
