The latest statistics available for chronic myeloid leukaemia (CML) in the UK are; incidence 2013 and mortality 2014. Reliable survival data for the UK is currently not available.

The ICD code Open a glossary item for CML is ICD-10 C92.1.

European Age-Standardised Rates were calculated using the 1976 European Standard Population (ESP) unless otherwise stated as calculated with ESP2013. ASRs calculated with ESP2013 are not comparable with ASRs calculated with ESP1976.

Lifetime risk estimates were calculated using incidence, mortality, population and all-cause mortality data for 2010-2012 due to the small number of cases.

Patient Experience data is for adult patients in England with a primary diagnosis of cancer, who were in active treatment between September and November 2013 and who completed a survey in 2014.

Deprivation gradient statistics were calculated using incidence data for three time periods: 1996-2000, 2001-2005 and 2006-2010 and for mortality for two time periods: 2002-2006 and 2007-2011. The 1997-2001 mortality data were only used for the all cancers combined group as this time period includes the change in coding from ICD-9 to ICD-10. The deprivation quintiles were calculated using the Income domain scores from the Index of Multiple Deprivation (IMD) from the following years: 2004, 2007 and 2010. Full details on the data and methodology can be found in the Cancer by Deprivation in England NCIN report.
