Change in stomach cancer incidence rates since the early 1990s, UK

Stomach cancer is the 17th most common cancer in the UK, accounting for 2% of all new cancer cases (2015).[1-4]

In males in the UK, stomach cancer is the 13th most common cancer (2% of all new male cancer cases). In females in the UK it is the 18th most common cancer (1% of all new female cancer cases).

65% of stomach cancer cases in the UK are in males, and 35% are in females.

Stomach cancer incidence rates (European age-standardised (AS) rates Open a glossary item ) for persons are significantly higher than the UK average in Wales, and similar to the UK average in all other UK constituent countries.

Stomach cancer incidence is strongly related to age, with the highest incidence rates being in older people. In the UK in 2013-2015, on average each year around half (51%) of new cases were in people aged 75 and over.[1-4

Age-specific incidence rates rise steadily from around age 45-49 and more steeply from around age 65-69. The highest rates are in the 85 to 89 age group for males and females.

Incidence rates are significantly higher in males than females in a number of (mainly older) age groups. The gap is widest at age 65 to 69, when the age-specific incidence rate is 2.6 times higher in males than females.

For stomach cancer, like most cancer types, incidence increases with age. This largely reflects cell DNA damage accumulating over time. Damage can result from biological processes or from exposure to risk factors. A drop or plateau in incidence in the oldest age groups often indicates reduced diagnostic activity perhaps due to general ill health.

Stomach cancer European age-standardised (AS) Open a glossary item incidence rates for males and females combined decreased by 50% in the UK between 1993-1995 and 2013-2015.[1-4] The decrease was of a similar size in males and females.

For males, stomach cancer AS incidence rates in the UK decreased by 52% between 1993-1995 and 2013-2015. For females, stomach cancer AS incidence rates in the UK decreased by 49% between 1993-1995 and 2013-2015.

Over the last decade in the UK (between 2003-2005 and 2013-2015), stomach cancer AS incidence rates for males and females combined decreased by 29%. In males AS incidence rates decreased by 31%, and in females rates decreased by 28%.

Stomach Cancer (C16), European Age-Standardised Incidence Rates, UK, 1993-2015

Stomach cancer incidence rates have decreased overall in all broad adult age groups in males and females combined in the UK since the early 1990s.[1-4] Rates in 25-49s have decreased by 27%, in 50-59s have decreased by 47%, in 60-69s have decreased by 59%, in 70-79s have decreased by 50%, and in 80+s have decreased by 45%.

Stomach Cancer (C16), European Age-Standardised Incidence Rates, By Age, UK, 1993-2015

For stomach cancer, like most cancer types, incidence trends largely reflect changing prevalence of risk factors and improvements in diagnosis and data recording. Recent incidence trends are influenced by risk factor prevalence in years past, and trends by age group reflect risk factor exposure in birth cohorts.

Overall stage at diagnosis

A moderate proportion (62-73%) of stomach cancer cases in England, Scotland and Northern Ireland have stage at diagnosis recorded.[1-3]

Stomach cancer patients with a known stage are most commonly diagnosed at stage IV (46-57%). More patients with a known stage are diagnosed at a late stage (69-75% are diagnosed at stage III or IV), than an early stage (25-31% are diagnosed at stage I or II).[1-3]

The stage distribution for each cancer type will reflect many factors including how the cancer type develops, the way symptoms appear, public awareness of symptoms, how quickly a person goes to see their doctor and how quickly the cancer is recognised and diagnosed by a doctor. It might also relate to whether a national screening programme that can detect early stage disease exists for that cancer type, along with the extent of uptake of that programme.

A cancer type associated with a large proportion of early stage diagnoses could be one that is more likely to be symptomatic at an earlier stage of development, with recognisable symptoms rather than more generic ones.

The largest proportion of stomach cancer cases occur in the cardia, with much smaller proportions in the pyloric antrum and body of the stomach (2010-2012).[1-4]

The proportion of cases in the cardia is higher in males (34.0%) than females (19.7%) and there are no marked sex differences in other parts of the stomach.[1-4]

A large proportion of cases did not have the specific part of the stomach recorded in cancer registry data, or overlapped more than one part.[1-4]

Cases and percentages may not sum due to rounding

Most stomach cancers (around 95%) are adenocarcinomas Open a glossary item which may be further classified into 'intestinal' and 'diffuse' type.

'Intestinal' adenocarcinomas are associated with a history of atrophic gastritis, have better survival and are associated with older patients, whereas the 'diffuse' adenocarcinomas are more common, with poorer survival and occur more frequently in women and people with blood group 'A'.[1]

Other stomach malignant histologies include lymphomas and leiomyosarcomas.

Stomach cancer incidence rates are projected to fall by 17% in the UK between 2014 and 2035, to 11 cases per 100,000 people by 2035.[1] This includes a larger decrease for males than for females.

For males, stomach cancer European age-standardised (AS) Open a glossary item incidence rates in the UK are projected to fall by 23% between 2014 and 2035, to 15 cases per 100,000 by 2035.[1] For females, rates are projected to fall by 9% between 2014 and 2035, to 8 cases per 100,000 by 2035.[1]

About this data

Data is for: UK, 1979-2014 (observed), 2015-2035 (projected), ICD-10 C16

Projections are based on observed incidence and mortality rates and therefore implicitly include changes in cancer risk factors, diagnosis and treatment. It is not possible to assess the statistical significance of changes between 2014 (observed) and 2035 (projected) figures. Confidence intervals are not calculated for the projected figures. Projections are by their nature uncertain because unexpected events in future could change the trend. It is not sensible to calculate a boundary of uncertainty around these already uncertain point estimates. Changes are described as 'increase' or 'decrease' if there is any difference between the point estimates.

There is evidence for an association between stomach cancer incidence and deprivation for both males and females in England.[1] England-wide data for 2006-2010 show European age-standardised Open a glossary item incidence rates are 86% higher for males living in the most deprived areas compared with the least deprived, and 93% higher for females.[1]

Stomach Cancer (C16), European Age-Standardised Incidence Rates by Deprivation Quintile, England, 2006-2010

The estimated deprivation gradient in stomach cancer incidence between people living in the most and least deprived areas in England has narrowed for males in the period 1996-2010, but has not changed for females.[1] It has been estimated that there would have been around 1,400 fewer cancer cases each year in England during 2006-2010 if all people experienced the same incidence rates as the least deprived.[1

About this data

Data is for UK, 2006-2010, ICD-10 C16

Deprivation gradient statistics were calculated using incidence data for 2006-2010. The deprivation quintiles were calculated using the Income domain scores from the Index of Multiple Deprivation (IMD) from the following years: 2004, 2007 and 2010. Full details on the data and methodology can be found in the Cancer by Deprivation in England NCIN report.

Age-standardised rates for White males with stomach cancer range from 14.1 to 14.7 per 100,000. Rates for Asian males are significantly lower, ranging from 5.2 to 8.5 per 100,000 whereas rates for Black males are significantly higher, ranging from 16.1 to 25.6 per 100,000. For females there is a similar pattern - the age-standardised rates for White females range from 5.5 to 5.8 per 100,000, while rates for Asian females are significantly lower, ranging from 2.7 to 5.0 per 100,000, and the rates for Black females are significantly higher ranging from 6.5 to 11.9 per 100,000.[1]

Ranges are given because of the analysis methodology used to account for missing and unknown data. For stomach cancer, 33,789 cases were identified; 18% had no known ethnicity.
