Survival

Survival depends on many different factors. It depends on your individual condition, type of cancer, treatment and level of fitness. So no one can tell you exactly how long you will live. 

These are general statistics based on large groups of patients. Remember, they can’t tell you what will happen in your individual case.

Your doctor can give you more information about your own outlook (prognosis).

You can also talk about this with the Cancer Research UK nurses on freephone 0808 800 4040, from 9am to 5pm, Monday to Friday.

Survival statistics

No UK-wide statistics are available for CML survival.

These statistics are for people with CML in England, diagnosed between 2008 and 2010. They come from the National Cancer Intelligence Network.

Generally for CML more than 70 out of 100 men (more than 70%) and almost 75 out of 100 women (almost 75%) will survive their leukaemia for 5 years or more after they are diagnosed. This is for all ages. Younger people tend to have a better outlook than older people. 

For people aged between 15 and 64, almost 90 out of 100 (almost 90%) will survive their leukaemia for 5 years or more after they are diagnosed. 

For people aged 65 or over, more than 40 out of 100 (more than 40%) will survive their leukaemia for 5 years or more.

What affects survival

Your outlook depends on the stage of your CML. This means how advanced it is when you are diagnosed. CML is divided into 3 phases: chronic phase, accelerated phase or blast phase. Most people are diagnosed in the chronic phase.

Your outlook also depends on your response to treatment and your general health.

CML is often a slowly developing condition and treatment can keep it under control for many years. Targeted cancer drugs work very well. People can go into remission for many years. This is when the disease isn’t active, you don't have symptoms and it doesn't show up in your blood tests.

If CML comes back (relapses), further treatment can often achieve a second remission. If targeted cancer drugs don't work, you’re likely to have intensive treatment with a stem cell or bone marrow transplant.

CML that has entered the blast phase is more difficult to manage. But treatment can sometimes get it back into chronic phase, where it’s not so difficult to keep under control. If CML in blast phase doesn’t respond to treatment, unfortunately you are more likely to live for months, rather than years.

About these statistics

The term 5 year survival doesn't mean that you will only live for 5 years. It relates to the number of people who are still alive 5 years after their diagnosis of cancer. Some people live much longer than 5 years.

Clinical trials

Doctors continue to try to improve the treatments and outlook for people with CML through clinical trials.
