As National Statistician, I have been asked to reply to your recent question asking how many deaths resulting from colorectal cancers there were in each year between 2002 and 2007 in each region; what per capita figure for the whole population this figure represents; and what five year survival rates were in each year in each region. (206692)
The tables attached provide the number of deaths where colorectal cancer was the underlying cause of death in each English government office region by sex (table 1), and age standardised mortality rates for each English government office region by sex (table 2), for 2002 to 2006 (the latest year available).
The latest relevant five year survival rates that are available are five year age-standardised relative survival rates by government office region, for cancer of the colon, for adult patients diagnosed during 1997-1999 and followed up to the end of 2004. These figures, and comparable figures for patients followed up to the end of 2002 and 2003, are available to download from the National Statistics website at:
Five year survival rate figures are not available for colorectal (bowel) cancer or cancer of the rectum.

|(1) Age-standardised mortality rates per 100,000 population, standardised to the European Standard Population. Age-standardised rates are used to allow comparison between populations which may contain different proportions of people of different ages.|
(2) Confidence intervals (CIs) are a measure of the statistical precision of an estimate and show the range of uncertainty around the estimated figure. Calculations based on small numbers of events are often subject to random fluctuations. As a general rule, if the confidence interval around one figure overlaps with the interval around another, we cannot say with certainty that there is more than a chance difference between the two figures.
