What Is the Prognosis for Chronic Leukemia?


Quick Answer

The average five-year survival rate for people with chronic lymphocytic leukemia, or CLL, is 50 to 80 percent, says Healthline. There are two types of CLL, and a prognosis depends on which kind a person has. People with slow-growing CLL generally live longer than people with fast-growing CLL.

One study of CLL found a five-year survival rate of 60.2 percent and a 10-year survival rate of 43.8 percent, according to Healthline. The figures in this study are based on people with both types of CLL. Several factors affect an individual's prognosis, including the stage of the cancer, the person's age, high levels of microglobulin in the blood and certain genetic conditions. The diffusion pattern of leukemia cells in bone marrow also affects the prognosis. People with chronic leukemia can be effectively treated for years, but it is not entirely curable.

Survival rates are influenced by many factors, and it is not possible to determine how long a particular individual can live with CLL, says the American Society of Clinical Oncology. Statistics on survival rates exclude people who die from other conditions, and they don't necessarily take into account recent or current medical techniques because they are measured in five-year intervals. Chronic lymphocytic leukemia is the most common type of this cancer among adults, but it is very rare in children.
