SURVIVAL for people diagnosed with Chronic Myeloid Leukaemia (CML) has risen by nearly half, with around 58 per cent of people surviving their disease for at least five years compared with only around 40 per cent in the late 1990s, according to a new report from the National Cancer Intelligence Network (NCIN), published today (Wednesday)*.

The improvements are largely down to a family of drugs called Tyrosine Kinase Inhibitors (TKIs) which have now become the standard treatment for the disease. The first of these was imatinib (Glivec), which was licensed in 2001.

The Northern and Yorkshire Cancer Registry and Information Service (NYCRIS), on behalf of the NCIN Haematology Site Specific Clinical Reference Group (SSCRG), looked at the rates of people in England getting, dying from and surviving a range of different blood cancers between 1995 and 2008. And it is the first national study in England to look at survival for different types of leukaemia.

For patients diagnosed with CML, researchers found that the chance of surviving the disease for at least five years after diagnosis rose from 41 per cent to 57 per cent in men and from 38 per cent to 59 per cent in women between the late 1990s and the early 2000s**.

CML is a relatively rare form of leukaemia*** that mostly affects older people, with around 700 cases diagnosed in the UK every year****.

Dr Robin Ireland, chair of the SSCRG at the NCIN, said: “It’s really exciting to see the enormous difference new drugs can make in treating cancer. And, as this new data shows, TKI’s can be considered a revolutionary treatment for Chronic Myeloid Leukaemia. 

“Basic research has given us a greater biological understanding of cancer tumours, which has led to the development of successful targeted cancer drugs that are now the first line treatment for CML. TKIs target cancer cells by blocking the molecules they make, which stops them from multiplying. These drugs have completely changed the outlook for patients with this disease and it’s the first example of our improved understanding of cell molecular biology leading to the design of a specific inhibitor of the disease.

”Dr Steven Oliver, Haematological Cancer Epidemiology Lead at NYCRIS and lead author of the report, said: “This report shows that, although the number of people developing Chronic Myeloid Leukaemia hasn’t changed much since 2001, survival from the disease has greatly improved.

“What’s even more promising is that, in the last four years, second and third generations of these drugs have been developed. We believe more and more CML patients have been receiving TKI’s and we’d predict that the improvements in survival should be even greater in the future.

”Chris Carrigan, head of the National Cancer Intelligence Network (NCIN), said: “Being able to link data on the diagnosis, treatment and outcomes for cancer patients allows us to identify where improved cancer care is having an effect on peoples lives. The improvements in survival demonstrated here highlight the difference that effective treatments can make.”

Notes to Editors:

*Haematological Malignancies in England: cancers diagnosed 2001 – 2008.Note that analyses of deaths from blood cancers for 2001-2008 were also reported, along with 5-year survival figures for patients diagnosed with different blood cancers in 1995-1999 compared with those diagnosed in 2000-2003.

**Absolute change in CML 5-year survival rates, in England, 1995-1999 compared with 2000-2003. Male rates 40.7% and 56.9%; female rates 38.4% and 58.7%, in 1995-1999 and 2000-2003 respectively.

***Leukaemias are a group of malignant diseases that affect the production of white blood cells – the body’s guards against foreign cells and infections. The different types of leukaemia affect different organs and vary in how quickly they spread. Different types of leukaemia affect different age groups and there are some wide differences in survival found across the age groups in certain forms of the disease.

**** There were 710 cases of CML registered in 2010 in the UK (Cancer Research UK Statistical Information Team)The NICE guidance recommends standard-dose imatinib as the first-line treatment for CML.

About the National Cancer Intelligence Network (NCIN)


  • The NCIN was established in June 2008 and its remit is to coordinate the collection, analysis and publication of comparative national statistics on diagnosis, treatment and outcomes for all types of cancer
  • As part of the National Cancer Research Institute, the NCIN aims to promote efficient and effective data collection at each stage of the cancer journey
  • Patient care will be monitored by the NCIN through expert analyses of up-to-date statistics
  • The NCIN will drive improvements in the standards of care and clinical outcomes through exploiting data
  • The NCIN will support audit and research programmes by providing cancer information

The National Cancer Intelligence Network will be part of Public Health England from 1 April 2013.
