ON THIS PAGE: You will find information about how many people are diagnosed with CML each year. You will also learn some general information on surviving the disease. Remember, survival rates depend on several factors. To see other pages, use the menu.
About 10% of all leukemia is CML. This year, an estimated 8,950 people (5,230 men and 3,720 women) in the United States will be diagnosed with CML. Most of these will be adults, with an average age of diagnosis at 64 years. CML is rare in children.
It is estimated that 1,080 deaths (610 men and 470 women) will occur this year.
The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate of people with CML depends on the phase of the disease, other biologic characteristics of the CML, and the disease’s response to treatment. The pace of CML treatment research is rapid, with several drug approvals in the past 2 decades. It is important to note that many of the new drugs for CML work very well, and survival rates are continually being measured based on these newer drugs.
Due in large part to recent scientific advances in the area of targeted treatments like imatinib (Gleevec), the 5-year survival rate for CML has nearly doubled from 31% for people diagnosed in the early 1990s to 66% for those diagnosed between 2006 and 2012, which are the most recent data available. And, a study of patients consistently taking the drug imatinib found that 90% lived at least 5 years.
It is important to remember that statistics on the survival rates for people with CML are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. People should talk with their doctor if they have questions about this information.
