Mr. Crausby: To ask the Chancellor of the Duchy of Lancaster how many cases of prostate cancer were diagnosed in each strategic health authority region in each of the last 11 years; and how many deaths from prostate cancer there were in each year. 
As National Statistician I have been asked to reply to your recent Parliamentary Question asking how many cases of prostate cancer were diagnosed, and how many deaths from prostate cancer there were, in each strategic health authority region in each of the last 11 years. (212813)
The most recent available figures for cancer incidence are for 2005. Figures requested are given in Table 1 below. The most recent available figures for cancer deaths are for 2006. Figures requested are given in Table 2 below.
|Table 1: Registrations of newly diagnosed cases of prostate cancer( 1) , males, by Strategic health authority, 1995 to 2005|
|(1) Prostate cancer is coded to C61 in the International Classification of Diseases 10th Revision (ICD-10)|

|(1 )Prostate cancer was defined using the International Classification of Diseases, Ninth Revision (ICD-9) code 185 for the years 1996 to 2000, and the International Classification of Diseases, Tenth Revision (ICD-10) code C61 for the years 2001 to 2006. The introduction of ICD-10 in 2001 had a significant effect on mortality rates for some diseases, causing a discontinuity in mortality trends for these causes of death. However ONS practice is not to adjust the historical numbers of deaths shown in PQ answers. More information on this issue can be found at www.statistics.gov.uk/icd10mortality. For prostate cancer, the introduction of ICD-10 caused an increase of 3.8 per cent. in the number of deaths. An article specifically examining the changes for cancer trends was published in Health Statistics Quarterly 23*. This article also presents comparability ratios (the ratio of the number of deaths coded to a cause in ICD-10 to the number coded to the equivalent cause in ICD-9) for the most common cancer sites.|
