Footnotes:

*Hybrid estimate for 2007-2009 is the most up-to-date survival estimate and is based on follow-up of all cases alive at any point during this period,

supplemented by follow-up 2005-2009 for cases diagnosed in 2005 or 2006 (to provide more reliable estimation of the first two years of survival).

In practice, the hybrid estimate for 2007-2009 is similar to the most recent (incomplete) cohort, i.e. cases diagnosed 2003-2007, reflecting substantial overlap of data.

# Age-standardized figures use the standard patient population proposed for this cancer by:

Corazziari I., Quinn M. & Capocaccia R. 2004. Standard cancer patient population for age standardising survival ratios. Eur J Cancer 40: 2307-2316.

(Population weights = age 20-44 x27000, 45-54 x17000, 55-64 x21000, 65-74 x20000, 75-99 x14000, total 99000 for this cancer)

## For comparison, the age-standardized average survival is quoted for countries (including Ireland) that participated in the EUROCARE-4 study:

Sant M. et al. 2009. EUROCARE-4. Survival of cancer patients diagnosed in 1995-1999. Results and commentary. Eur J Cancer 45: 931-991.

Exclusions (as in EUROCARE):

Patients aged <15 or >99 at diagnosis; death-certificate-only (DCO) and autopsy-only cases; second or subsequent malignancies in the same patient

(or the less serious of two or more synchronously-diagnosed malignancies); in situ carcinomas and tumours of uncertain behaviour.

Cancer registration is a dynamic process and information is continually updated on our database.
