Cancer Survival by NHS England Area Team - Patients diagnosed

1. Key findings

One-year net survival from cancers of the oesophagus, stomach, colon, lung, breast (women) and cervix has improved by between 3% and 19% for adults diagnosed in England in 2011, compared to those diagnosed in 1996
Five-year net survival for these same cancers has improved by between 2% and 9% for adults diagnosed in 2006, compared to those diagnosed in 1996
For women diagnosed with breast cancer in 2011, there was very little variation in one-year survival across the 25 NHS England Area Teams: the national average value was 96.4%, and the range between the highest and lowest values was only 1.3%
For five-year survival for women diagnosed with breast cancer in 2006, the geographic variation around the national average (84.1%) was slightly wider, at 4.0%
Disparities in net survival across the 25 NHS England Area Teams were highest for one-year net survival for cancers of the oesophagus (men), stomach, colon (women) and lung (women) in 2011, with differences of over 10% between Area Teams. These disparities were less marked for five-year net survival

2. Summary

This report presents one-year and five-year age-standardised net survival estimates for the 25 NHS England Area Teams, for patients who were diagnosed with a cancer of the oesophagus, stomach, colon, lung, breast (women) or cervix during 1996–2011 and followed up to 31 December 2012 (see Background Notes 1−3). One-year survival estimates are reported for patients diagnosed in 1996, 2001, 2006 and 2011, and five-year survival for those diagnosed in 1996, 2001 and 2006.

3. Results

The 25 NHS England Area Teams were created on 1 April 2013. For the purpose of these analyses, patients have been assigned to the Area Team that includes their residence when they were diagnosed between 1996 and 2011.

Estimates of one-year and five-year age-standardised net survival (%) are presented for each of the six cancers in tables and charts for each NHS England Area Team, by sex and calendar period. The survival estimates are age-standardised to compensate for differences in the age profile of cancer patients between Area Teams, and for changes in these age profiles over time (see Background Note 5).

One-year survival is above 60% for cancers of the colon, breast and cervix, and five-year survival for these cancers is above 45% (Figures 1A and 1B). For cancers of the oesophagus, stomach and lung, however, one-year survival is below 50% and five-year survival below 20%.

At the national level an upward trend in net survival was observed for all six cancers. The largest improvement in one-year survival among men occurred for cancers of the oesophagus, where survival increased by 19% from 26.7% for those diagnosed in 1996 to 45.4% for those diagnosed in 2011. Five-year survival for men with colon cancer increased by 8% from 45.2% for those diagnosed in 1996 to 53.4 % for those diagnosed in 2006. For women the largest improvement in one-year survival was for cancer of the lung, where survival increased by 13% from 21.9% for those diagnosed in 1996 to 34.7% for those diagnosed in 2011. Five-year survival for women increased the most for those diagnosed with breast cancer, increasing by 9% from 75.2% in 1996 to 84.1% in 2006.

The range in one-year survival between NHS England Area Teams with the highest and lowest survival in 2011 was widest for men diagnosed with stomach cancer at 14.2% and narrowest for women diagnosed with breast cancer at 1.3% (Table 1A). For five-year survival the range between NHS England Area Teams in 2006 was widest for women diagnosed with colon cancer at 12.0% and narrowest for men diagnosed with lung cancer at 3.7% (Table 1B).

These estimates should not be used to rank NHS England Area Teams by their survival, because a change of just 1 or 2% may radically alter the ranking of a given Area Team, especially where the range of estimates is very narrow.

Figure 2 presents a map of the 25 NHS England Area Teams. The geographic patterns of one-year survival (patients diagnosed in 2011) for cancer of the oesophagus, stomach, colon, lung, breast (women) and cervix are mapped in Figures 3A, 4A, 5A, 6A, 7A and 8A respectively. Comparable maps for five-year survival (patients diagnosed in 2006) are mapped in Figures 3B, 4B, 5B, 6B, 7B and 8B respectively.

8. Lung cancer

One-year age-standardised net survival improved between 1996 and 2011, however survival remained low, ranging between 28.3% and 34.6% in men and between 29.6% and 40.7% in women (Tables and Figures D1 and D2 (341.5 Kb Excel sheet)). Five-year age-standardised net survival doubled in three NHS England Area Teams for men in the North of England Region: Greater Manchester, Lancashire, and South Yorkshire and Bassetlaw, while survival for women doubled in five NHS England Area Teams: Lancashire; South Yorkshire and Bassetlaw; Bristol, North Somerset, Somerset and South Gloucestershire; Kent and Medway; and Thames Valley. Despite these improvements five-year age-standardised net survival remained under 20% for both men and women. Five-year age-standardised net survival varied between NHS England Area Teams ranging from 5.9% to 9.6% in men and 7.3% to 16.6% in women (Tables and Figures D3 and D4 (341.5 Kb Excel sheet)).

11. Users and uses

Key users of cancer survival estimates include the Department of Health, academics and researchers, cancer charities, cancer registries, other government organisations, researchers within ONS, the media, and the general public. The Department of Health uses cancer survival figures to brief parliamentary ministers, and as part of the evidence base to inform cancer policy and programmes, for example in drives to improve survival rates. Cancer survival estimates will also be used to measure progress against NHS Outcomes Framework indicators. Academics and researchers use the figures to inform their own research. Similarly cancer registries and other government organisations use the figures to carry out individual and collaborative projects to apply subject knowledge to practice. Charities use the data so they can provide reliable and accessible information about cancer to a wide range of groups, including patients and health professionals via health awareness campaigns and cancer information leaflets/web pages. Researchers within ONS use the data to support further research and to publish alongside other National Statistics.

12. Policy context

In ‘Improving Outcomes: A Strategy for Cancer’ (January 2011), the Department of Health stated that although improvements have been made in the quality of cancer services in England, a significant gap remains in survival compared with the European average. Survival estimates for cervical, colorectal and breast cancer are some of the lowest among Member States of the Organisation for Economic Co-operation and Development (OECD) (figures for cancer survival in OECD countries are available from the OECD website). The strategy document sets out how the Department of Health aims to improve outcomes for all cancer patients and improve cancer survival, with the aim of saving an additional 5,000 lives every year by 2014/15.

Outcomes strategies set out how the NHS, public health and social care services will contribute to the ambitions for progress agreed with the Secretary of State in each of the high-level outcomes frameworks. The indicator set for the NHS Outcomes Framework 2013 to 2014 – focus on measuring health outcomes include one- and five-year cancer survival indicators for all cancers combined, and for colorectal, breast and lung cancers combined.

National cancer registration data for England were received from the National Cancer Registry at the Office for National Statistics (ONS), which collates cancer registrations submitted by regional cancer registries in England. The Health and Social Care Information Centre (HSCIC) updates these records with the registration of death or emigration. The data used in these analyses were extracted from the live database at ONS on 2 July 2013 and provided to the Cancer Research UK Cancer Survival Group at the London School of Hygiene and Tropical Medicine on the 4 July 2013.

All adults (15–99 years) who were diagnosed with a first, invasive, primary, malignancy during the period 1996–2011 were eligible for inclusion in the analyses. We excluded patients who were diagnosed with a tumour that was benign (behaviour code 0), in situ (2) or of uncertain behaviour (1). Patients were excluded if their cancer was only registered from a death certificate. Patients with zero recorded survival time were included in the analyses with one day added to their survival. Table 2 shows the number of patients excluded and Table 3 shows the final number of patients in each NHS England Area Team who were included in the analyses.

Net survival in a population of cancer patients is their survival from the cancer of interest in the absence of other causes of death. It was estimated at one and five years after diagnosis for each cancer, sex and year of diagnosis. Net survival was estimated with an excess hazard model in which the all-cause mortality is modelled as the sum of the excess (cancer-related) mortality hazard and the expected (or background) mortality. The background mortality is defined by life tables from the general population. This approach enables population-level cancer survival to be estimated in the absence of detailed data on the cause of death. To obtain an unbiased estimation of net survival, age needs to be carefully modelled to account for the informative censoring associated with age (Danieli et al., 2012).
We used flexible parametric models (Royston and Parmar, 2002) with age and year of diagnosis as main effects and an interaction between age and year of diagnosis. We also examined interactions between year and follow-up time and between age and follow-up time to deal with potential non-proportionality of the excess hazards over time since diagnosis. The Akaike Information Criterion (AIC) (Akaike, 1974) was used to select the best-fitting statistical model using the relative goodness of fit. The publicly available program, stpm2, was used to estimate net survival (Lambert and Royston, 2009). Analyses were performed in Stata 13 (Statacorp, 2013)
Life tables were constructed for the years 1996, 2001, and 2006 using the mid-year population estimates and the mean annual number of deaths in the three years centred on those index years (Cancer Research UK Cancer Survival Group, 2004). Life tables for each year from 1996 to 2005 were created by linear interpolation. The life table for 2005 was used for 2006–11. Background mortality changes with time and varies by sex, age, socio-economic status and region, so life tables were created by single year of age, sex, region and deprivation quintile for each calendar year of death.
The age distribution of cancer patients at diagnosis changes with time and varies between NHS England Area Teams. Since survival also varies with age at diagnosis, robust summary comparisons of survival require control for these differences. The directly standardised overall survival figure for each cancer is a weighted average of the age-specific survival estimates, with standard weights taken from the proportionate distribution by age and sex of patients diagnosed in England and Wales during 1996–99.
Age-standardisation requires a set of survival estimates for each age group. It is not always possible to obtain an estimate for each combination of cancer, age group, sex and calendar year of diagnosis in geographic units with small populations because of the limited number of cases. In this situation, the missing estimate was replaced by the equivalent age-specific estimate for England.
A 95% confidence interval is a measure of the uncertainty around an estimate. It provides a range of values which contains the true population value with a 95% level of confidence.
NHS England was established in April 2013, following the Health and Social Care Act 2012. There are 25 NHS England Area Teams. The role of the area teams includes commissioning of primary care services (such as GP, dental and pharmacy services), supporting and developing Clinical Commissioning Groups, and working with local NHS and public health organisations. The NHS England Area Team boundaries were applied to the whole period 1996–2011, enabling geographic trends to be charted over time (Figure 2). NHS England Area Team populations range from 1.1 to 7.7 million (2011 figures) (NHS England, 2012), making them more suitable for detailed statistical comparison of survival than smaller health geographies such as Clinical Commissioning Groups.
Cancers were defined by codes in the International Classification of Diseases, Tenth Revision (ICD-10) and International Classification of Diseases for Oncology, Second Edition (ICD-O-2) (Ashley, 1990), see Table 2.
Differences between survival estimates for the two periods are taken as the arithmetic difference: for example, 12% is shown as 2% (not 20%) higher than 10%. Survival figures are rounded to one decimal place, but the differences are based on the exact underlying figures.
