Baltic Sea countries-Denmark, Estonia, Finland, Germany, Latvia, Lithu
ania, Poland, the Russian Federation and Sweden-have expressed deep in
terest in developing collaborative research projects chiefly in descri
ptive epidemiology of cancer. In order to assess potentials for joint
studies, an attempt was undertaken to characterize cancer registration
, cancer incidence patterns, temporal trends in cancer mortality and r
esearch productivity between these countries. Standards of cancer regi
stration are highest in the Nordic countries (Denmark, Finland, Sweden
). These countries and Germany are also doing more productive research
, Great differences in incidence and in mortality trends around the Ba
ltic Sea offer promising opportunities for epidemiologic studies. Scar
city of well-trained professional epidemiologists and other resources
in Latvia, Lithuania, Estonia and the Russian Federation is the main f
actor limiting the planning of joint large-scale epidemiologic studies
of cancer.
