Cancer research in the European Community and other non-EC countries.
OBJECTIVE
We assessed the scientific productivity in the field of cancer research of countries in the European Community (EC) and the most important non-EC countries by counting the number of papers published during the period 1988-1990 in 15 of the top scientific journals (as defined by the Journal Citation Reports, Oncology). The global and per capita data are presented for each country.


METHODS
Qualitative parameters like the impact factor and the half-life were also considered in the analysis. The selection of cancer journals with a high average quotation rate gave significant results. Introducing the average impact factor and half-life of each journal modified the results only slightly. The per capita data for each country were not corrected for the number of investigators working in oncology (a datum difficult to obtain). The parameters thus do not define the performance of the average investigator but are more "economic" parameters specifically related to the field of cancer research.


CONCLUSIONS
Small, wealthy Western countries tended to have an advantage over large, less developed countries, as expected. However, additional individual differences that could be of interest were present in the group of developed countries.
