CI5 - Cancer Incidence in Five Continents

Cancer Incidence in Five Continents – Volume XII

CI5 volume XII cover final pick 2022

09 October 2023.  IARC and IACR has launched Volume XII of Cancer Incidence in Five Continents (CI5). The CI5 series of volumes, published every five years, is a key source of information on the changing patterns of cancer incidence worldwide. The CI5 databases provide access to detailed information on the incidence of cancer recorded by population-based cancer registries (subnational or national).

The work of the CI5-XII Editorial Board[1 involved reviewing individual datasets (covering the period of diagnosis 2013–2017) from 670 population-based cancer registries, covering 812 populations in 104 countries.  

The overarching aim, as with every volume, is to ensure the published incidence data are sufficiently comparable, complete, and accurate to be a source of reference for studies on international variations in cancer risk. The resulting Volume XII compiles cancer incidence data from 455 cancer registries, covering 588 populations in 70 countries.

 Cancer Incidence in Five Continents: Earlier Editions

  • CI5 XI (Cancer Incidence in Five Continents Volume XI) contains information from 343 cancer registries in 65 countries about cancers diagnosed from 2008 to 2012. This website contains several utilities enabling the comparison of cancer rates across diverse populations and will be of interest to all those interested in understanding the burden of cancer in different regions of the world. The editors of Volume XI hope it will be of value to anyone wishing to build up knowledge about the causes of the disease and how to control it.  CI5-XI is now available in PDF format here:  IARC Scientific Publication No. 166
  • CI5PLUS (Cancer Incidence in Five Continents Time Trends). The CI5plus database contains updated annual incidence rates for 118 selected populations from 102 cancer registries published in CI5, for the longest period available (up to 2007), for all cancers and 27 major types (see the Cancer dictionary menu option). In addition, groups of cancer registries in the same country have been added (see the Cancer registry list menu option). CI5plus can be used for time trends analyses, but differences over time in registration practices and coding make it necessary to interpret trends with caution.
  • CI5 I-X (Cancer Incidence in Five Continents Volumes I to X). The material accessible through this application contains the basic data published in the ten volumes of CI5. In order to present this data within the same application, a common Cancer dictionary has been defined, so that some cancer sites are not available for all registries.
