Cancer mortality and predictions for 2018 in selected Australasian countries and Russia

Abstract

Background

Predicted cancer mortality figures and rates are useful for public health planning.

Materials and methods

We retrieved cancer death certification data for 10 major cancer sites and total cancers from the World Health Organization (WHO) database and population data from WHO and United Nations Population Division databases. We obtained figures for Russia, Israel, Hong Kong, Japan, the Philippines, Korea, and Australia in 1970–2015. We predicted numbers of deaths by age group and age-standardized rates (world population) for 2018 by applying a linear regression to mortality data of each age group over the most recent trend segment identified by a joinpoint regression model.

Results

Russia had the highest predicted total cancer mortality rates, 158.5/100 000 men and 84.1/100 000 women. Men in the Philippines showed the lowest rates for 2018 (84.6/100 000) and Korean males the most favourable predicted fall (21% between 2012 and 2018). Women in Korea had the lowest total cancer predicted rate (52.5/100 000). Between 1993 and 2018, i.e. by applying the 1993 rates to populations in subsequent years, a substantial number of cancer deaths was avoided in Russia (1 000 000 deaths, 821 000 in men and 179 000 in women), Israel (40 000 deaths, 21 000 in men and 19 000 in women), Hong Kong (63 000 deaths, 40 000 in men and 23 000 in women), Japan (651 000 deaths, 473 000 in men and 178 000 in women), Korea (327 000 deaths, 250 000 in men and 77 000 in women), and Australia (181 000 deaths, 125 000 in men and 56 000 in women). No appreciable reduction in cancer deaths was found in the Philippines.

Conclusion

Overall, we predicted falls in cancer mortality. However, these are less marked and later compared with the European Union and United States. Substantial numbers of deaths were avoided in all countries considered except the Philippines. Lung cancer mortality remains exceedingly high in Russian men, despite recent falls.
