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 15-44 x28000, 45-54 x17000, 55-64 x21000, 65-74 x20000, 75-99 x14000)

## For comparison, the age-standardized average survival (2000-2002) is quoted for countries (including Ireland) that participated in the EUROCARE-4 study:

Verdecchia A., Francisci S., Brenner H., et al. 2007. Recent cancer survival in Europe: a 2000-02 period analysis of EUROCARE-4 data. Lancet Oncol 8: 784-796.

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.
