Notes and data sources

Release 1 - May 2010

Coverage of cancer sites

Unless otherwise stated the cancer sites covered in this release are:

Male breast cancer

Both men and women may be diagnosed with breast cancer, although cases in men represent less than 1% of the total each year. The low number of cases in men means that it may be misleading to show rates for 'persons' and that much information is available only for females. This does not mean that there are no gender inequalities in breast cancer and the relatively rarity of male breast cancers may result in lower awareness amongst men and a lack of appropriate information.

Data Sources

Incidence

Incidence rate per 100,000

Age-standardised incidence rate per 100,000 (with 95% confidence intervals) for PCTs in 2004-6 are from the Cancer eAtlas.

Male:female incidence ratio

Age standardised incidence rate ratios (male:female) for the UK in 2006 are from NCIN - The Excess burden of Cancer in Men in the UK. The all cancers atlas shows data for all cancers excl. NMSC, breast and sex specific cancers (ICD-10 codes C00-C97 excl. C44, C50, C51-C58, C60-C63). Data in the colorectal atlas are for colon, rectum and anus (ICD-10 codes C18-C21).

Most:least deprived incidence ratio

Age-standardised incidence rate ratios (most deprived quintile:least deprived quintile) for England in 2000-2004 are from NCIN - Cancer Incidence by Deprivation.
Deprivation quintiles have been assigned using the Income Domain of the Index of Multiple Deprivation (IMD) 2007.

Black:White and Asian:White incidence ratios

Highest and lowest expected age-standardised incidence rate ratios for England in 2002-2006 are from NCIN and Cancer Research UK - Cancer Incidence and Survival by Major Ethnic Group. Highest and lowest expected ratios are based on different assumptions used when assigning ethnicity to patients without a valid ethnicity code and are not confidence intervals.

Survival

One year relative survival - PCT and cancer network level

One year relative survival estimates for PCTs and cancer networks in 2002-2006 are from the Cancer eAtlas. For individual cancer sites European consensus targets are shown. These are taken from the publication 'Local Awareness and Early Diagnosis Baseline Assessments: A Guide for Cancer Networks and Primary Care Trusts' and is based on 1995-9 EUROCARE data.

One year survival gap most:least deprived

Estimates of the gap in one year relative survival between the most and least deprived for England and Wales in 1996-1999 are from Trends and inequalities in survival for 20 cancers in England and Wales 1986-2001: population-based analyses and clinical commentaries - Br J Cancer 99 (suppl 1), 2008. The data in the colorectal atlas are for colon cancer only.
Deprivation quintiles were assigned using the Income Domain of the Index of Multiple Deprivation (IMD) 2000, derived separately for England and Wales.

Mortality

Mortality rate per 100,000

Age standardised mortality rates per 100,000 for PCTs in 2005-2007 are from the Cancer eAtlas.

Male:female mortality ratio

Age standardised mortality rate ratios for 2007 are from NCIN - The Excess burden of Cancer in Men in the UK. Data shown are for the UK. The 'All cancers' atlas shows data for all cancers excl. NMSC, breast and sex specific cancers (ICD-10 codes C00-C97 excl. C44, C50, C51-C58, C60-C63). Data in the 'Colorectal' atlas are for Colon, rectum and anus (C18-C21).

Mortality rate per 100,000 by age group

Mortality rates for cancer networks in 2003-2005, truncated for the specified age group are from the Cancer eAtlas.

Symptom awareness

Mean recall of nine cancer warning signs (with 95% confidence intervals) for the UK is from Robb K et al. (2009) Public awareness of cancer in Britain: a population-based survey of adults. Br J Cancer 101(Suppl 2): S18-S23. The nine signs were: lump or swelling, persistent unexplained pain, unexplained bleeding, persistent cough or hoarseness, persistent change in bowel or bladder habits, difficulty swallowing, change in the appearance of a mole, a sore that does not heal and unexplained weight loss.

Screening uptake

Cervical screening coverage

The proportions of each PCT's population eligible to be screened who are actually screened in 2008/9 (less than five years since last adequate test). These data are from the NHS Information Centre. Data on screening coverage are also available to NHS users in the Cancer Commissioning Toolkit.

Breast screening coverage

The proportions of each PCT's population eligible to be screened who are actually screened as at 31 March 2009 (less than three years since last test). These data are from the NHS Information Centre. Data on screening coverage are also available to NHS users in the Cancer Commissioning Toolkit.

Cancer waits

Referrals through two-week wait per 10,000 population

The number of cases (per 10,000 population per year) referred as an urgent GP referral for suspected cancer (two-week wait) for each PCT in Q1 2009/10 are from Department of Health - Cancer Reform Strategy: Achieving local implementation.

Two-week wait referrals with cancer

The percentage of patients from each PCT referred through the two-week wait pathway who were then diagnosed with cancer in Q3 2008/9 are from Department of Health - Cancer Reform Strategy: Achieving local implementation. The latest data are available to NHS users in the Cancer Commissioning Toolkit.

Patients diagnosed through two-week wait

The percentage of each PCT's patients diagnosed with cancer who were urgently referred for suspected cancer by their GP through the two-week wait pathway in Q3 2008/9 are from Department of Health - Cancer Reform Strategy: Achieving local implementation. The latest data are available to NHS users in the Cancer Commissioning Toolkit.

Compliance with 62-day treatment standard

Compliance with the 62-day treatment standard between urgent referral and first treatment for each PCT in Q3 2008/9 are from Department of Health - Cancer Reform Strategy: Achieving local implementation. The latest data are available to NHS users in the Cancer Commissioning Toolkit.

Prevalence

Lifetime prevalence

Estimates of lifetime cancer prevalence for the UK on the 31st December 2008 are from Maddams J et al. (2009) Cancer prevalence in the United Kingdom: estimates for 2008. Br J Cancer 101: 541-547. Data in the colorectal atlas are for colon, rectum and anus (ICD-10 codes C18-C21).

One-, five- and ten year prevalence

Estimates of one-, five- and ten year cancer prevalence for the UK on the 31st December 2006 are from NCIN - One, five and ten year cancer prevalence, UK, 2006.

Recording ethnicity

Cancer patients with ethnicity recorded

The percentage of each PCT's cancer patients who have at least one ethnicity code recorded in the National Cancer Data Repository (NCDR) during the period 2002-2006 is from NCIN analysis of the NCDR. Ethnicity codes have been obtained through the linkage of the NCDR to inpatient Hospital Episode Statistics (HES) where cancer is indicated for the patient. Ethnicity codes recorded for patients treated as outpatients or elsewhere will not appear in this database.

Mapping of PCTs to cancer networks

Where PCT level data are not available information at cancer network or national level is shown. This has required mapping each PCT to a single cancer network even though PCT and cancer network boundaries do not coincide. PCTs have been assigned to the cancer network in which the largest proportion of their population lives (always greater than 51%). Information about other relevant cancer networks may be easily obtained by selecting neighbouring PCTs. PCT assignments are to Cancer Network boundaries as at 1st October 2008 and are based on PCT populations in 2007. An excel speadsheet showing the proportions used is available for download.

Spearhead PCTs

The Spearhead Group consists of local authorities and PCTs based on the local authorities that are in the bottom fifth nationally for three or more of the following indicators:

Further details of the Spearhead Group are available from the Department of Health. A list of Spearhead PCTs is also available.
