New cases of uterine cancer

Uterine cancer was the 5th most commonly diagnosed cancer among females in Australia in 2013. It is estimated that it will remain the 5th most commonly diagnosed cancer among females in 2017.

In 2013, there were 2,511 new cases of uterine cancer diagnosed in Australia. In 2017, it is estimated that 2,861 new cases of uterine cancer will be diagnosed in Australia.

In 2013, the age-standardised incidence rate was 19 cases per 100,000 females. In 2017, it is estimated that the age-standardised incidence rate will be 19 cases per 100,000 females. The incidence rate of uterine cancer among females will increase with age from age group 20–24 until age group 65–69. It will then decrease for older age groups (Figure 1).

In 2017, it is estimated that the risk of a female being diagnosed with uterine cancer by her 85th birthday will be 1 in 42.

The number of new cases of uterine cancer diagnosed increased from 942 in 1982 to 2,511 in 2013. Over the same period, the age-standardised incidence rate increased from 14 cases per 100,000 females in 1982 to 19 cases per 100,000 females in 2013.

Deaths from uterine cancer

In 2014, uterine cancer was the 12th leading cause of cancer death among females in Australia. It is estimated that it will become the 13th most common cause of death from cancer among females in 2017.

In 2014, there were 494 deaths from uterine cancer in Australia. In 2017, it is estimated that this will decrease to 453 deaths.

In 2014, the age-standardised mortality rate was 3.4 deaths per 100,000 females. In 2017, it is estimated that the age-standardised mortality rate will be 2.8 deaths per 100,000 females. The mortality rate for uterine cancer will generally increase with age, particularly from age group 60–64 and older.

In 2017, it is estimated that the risk of a female dying from uterine cancer by her 85th birthday will be 1 in 259.

The number of deaths from uterine cancer increased from 223 in 1968 to 494 in 2014. Over the same period, the age-standardised mortality rate decreased from 4.7 deaths per 100,000 females in 1968 to 3.4 deaths per 100,000 females in 2014.

This line chart presents the estimated age-specific incidence (solid line) and mortality (dashed line) rates of uterine cancer for females in 2017. The age-specific incidence and mortality rates are shown on the primary (left) y-axis, with 5-year age groups from ages 0–4 to 85+ shown on the x-axis.

This line chart presents the estimated age-standardised incidence (solid line) and mortality (dashed line) rates (per 100,000) of cancer name for females over the period 1982–2013 for incidence and 1968–2014 for mortality. The age standardised incidence and mortality rates, expressed per 100,000 persons, are shown on the primary (left) y-axis. Years from 1968 to 2014 are presented on the x-axis.

Survival from uterine cancer

In 2009–2013, females diagnosed with uterine cancer had a 83% chance of surviving for 5 years compared to their counterparts in the general Australian population.

Between 1984–1988 and 2009–2013, 5-year relative survival from uterine cancer improved from 76% to 83%.

Survivorship population for uterine cancer

The survivorship population is measured using prevalence data. Prevalence refers to the number of people alive who have previously been diagnosed with uterine cancer.

The prevalence for 1, 5 and 31 years given below are the number of people living with uterine cancer at the end of 2012 who had been diagnosed in the preceding 1, 5 and 31 years respectively.

At the end of 2012, there were 2,263 females living who had been diagnosed with uterine cancer that year, 9,589 females who had been diagnosed with uterine cancer in the previous 5 years (from 2008 to 2012) and 26,879 females who had been diagnosed with uterine cancer in the previous 31 years (from 1982 to 2012).


Data notes

International Statistical Classification of Diseases and Related Health Problems Version 10 (ICD–10)

Cancer is classified by the International Statistical Classification of Diseases and Related Health Problems Version 10 (ICD–10). This is a statistical classification, published by the World Health Organization, in which each morbid condition is assigned a unique code according to established criteria.

Estimations

Future estimations for incidence and mortality are a mathematical extrapolation of past trends. They assume that the most recent trends will continue into the future, and are intended to illustrate future changes that might reasonably be expected to occur if the stated assumptions continue to apply over the estimated period. Actual future cancer incidence and mortality rates may vary from these estimations. For instance, new screening programs may increase the detection of new cancer cases; new vaccination programs may decrease the risk of developing cancer; and improvements in treatment options may decrease mortality rates.

Incidence

Cancer incidence indicates the number of new cancers diagnosed during a specified time period (usually one year).

The 2013 national incidence counts include estimates for NSW because the actual data were not available. Note that actual data for the Australian Capital Territory do not include cases identified from death certificates.

The 2017 estimates are based on 2004–13 incidence data. Due to rounding of these estimates, male and female incidence may not sum to person incidence.

Mortality

Cancer mortality refers to the number of deaths occurring during a specified time period (usually one year) for which the underlying cause of death is cancer.

The 2017 estimates are based on mortality data up to 2013. Joinpoint analysis was used on the longest time series of age–standardised rates available to determine the starting year of the most recent trend.

Prevalence

Prevalence of cancer refers to the number of people alive with a prior diagnosis of cancer at a given time. It is distinct from incidence, which is the number of new cancers diagnosed within a given period of time. The longest period for which it is possible to calculate prevalence using the available national data (from 1982 to 2012) is currently 31 years so this is used to provide an estimate of the ‘total’ prevalence of cancer as at the end of 2012, noting that people diagnosed with cancer before 1982 aren’t included.

Age standardised rates

Incidence and mortality rates expressed per 100,000 population are age–standardised to the Australian population as at 30 June 2001.
