New cases

In 2016, there were 2,197 new cases of stomach cancer diagnosed in Australia (1,462 males and 735 females). In 2020, it is estimated that 2,246 new cases of stomach cancer will be diagnosed in Australia (1,514 males and 732 females).

  • More information about incidence rates for the most common cancers diagnosed can be found on the NCCI website in the ‘Cancer incidence’ section (https://ncci.canceraustralia.gov.au/diagnosis/cancer-incidence/cancer-incidence) 

In 2016, the age-standardised incidence rate was 7.9 cases per 100,000 persons (11 for males and 4.9 for females). In 2020, it is estimated that the age-standardised incidence rate will be 7.3 cases per 100,000 persons (10 for males and 4.5 for females). The incidence rate for stomach cancer is expected to increase with age, peaking at age group 80–84.

Notes: 

  • Data sourced from AIHW Cancer Data in Australia 2020 web report and supplementary data tables

The number of new cases of stomach cancer diagnosed increased from 1,825 (1,153 males and 672 females) in 1982 to 2,197 in 2016. Over the same period, the age-standardised incidence rate decreased from 16 cases per 100,000 persons (23 for males and 10 for females) in 1982 to 7.9 cases per 100,000 in 2016.

Deaths 

In 2018, there were 1,138 deaths from stomach cancer in Australia (712 males and 426 females). In 2020, it is estimated that there will be 1,140 deaths (705 males and 435 females).

In 2018, the age-standardised mortality rate was 3.8 deaths per 100,000 persons (5.1 for males and 2.6 for females). In 2020, it is estimated that the age-standardised mortality rate will be 3.6 deaths per 100,000 persons (4.8 for males and 2.6 for females). The mortality rate for stomach cancer is expected to increase with age.

Notes: 

  • Data sourced from AIHW Cancer Data in Australia 2020 web report and supplementary data tables

The number of deaths from stomach cancer decreased from 1,398 (874 males and 524 females) in 1982 to 1,138 in 2018. Over the same period, the age-standardised mortality rate decreased from 12 deaths per 100,000 persons (18 for males and 8.1 for females) in 1982 to 3.8 deaths per 100,000 in 2018. 

Survival 

In 2012–2016, individuals diagnosed with stomach cancer had a 31 % chance (30% for males and 33% for females) of surviving for five years compared to their counterparts in the general Australian population. Between 1987–1991 and 2012–2016, five-year relative survival for stomach cancer improved from 19% to 31%.

Prevalence 

At the end of 2015, there were 1,544 people living who had been diagnosed with stomach cancer that year, 4,482 people living who had been diagnosed with stomach cancer in the previous 5 years (from 2011 to 2015) and 10,040 people living who had been diagnosed with stomach cancer in the previous 34 years (from 1982 to 2015).
