Abstract
Baltic Sea countries—Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, the Russian Federation and Sweden—have expressed deep interest in developing collaborative research projects chiefly in descriptive 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 research productivity between these countries. Standards of cancer registration 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 Baltic Sea offer promising opportunities for epidemiologic studies. Scarcity of well-trained professional epidemiologists and other resources in Latvia, Lithuania, Estonia and the Russian Federation is the main factor limiting the planning of joint large-scale epidemiologic studies of cancer.
