Cancer Incidence in Five Continents (CI5) is the result of a long
collaboration between the International Agency for Research on Cancer and the
International Association of Cancer Registries. The publications provide data
on cancer incidence collected by population-based cancer registries over more
than fifty years, and the contents of this collected edition represent the
results of this effort. Their work deserves gratitude not only from
investigators who use the information they provide, but also from all those who
may benefit from the increase in our knowledge of cancer patterns and trends.
Particular thanks are due to those cancer registries who agreed to make their
results available through CI5plus, a level of detail not hitherto possible in
the printed volumes.
We would like to recognize and acknowledge also the work of the 30 editors who
were involved in collecting, evaluating and preparing the data appearing in one
or more of the ten volumes of CI5. Particular thanks are due to the late Sir
Richard Doll, who was in large measure responsible for bringing to fruition the
idea of creating a source of comparable international data on cancer incidence
for the purposes of research into cancer cause and prevention.
