Impact assessment of oncology research in the European Union

In this study the distribution of papers published by authors from the European Union (EU) in oncological journals was analysed, as was the impact of oncological research in the EU compared with that produced in other countries. Papers published during 1995 in the oncological journals listed by ISI (Institute for Scientific Information, Philadelphia, U.S.A.) were downloaded. The parameters of impact factor (IF), source country population and gross domestic product (GDP) were considered. An analysis of the key words, both those reported by the authors and those attributed by ISI, was carried out using a special purpose program. 36.5% of papers published in oncological journals come from the EU (the U.K., Italy, Germany and France ranking at the top) and 40.7% from the U.S.A. The mean IF was 2.4 for EU papers, 3.3 for the US and 2.4 for other countries. Our data confirm that smaller countries performed better than larger ones. The key words analysis shows that the leading fields of research were breast cancer for diseases, cisplatin for drugs and p53 for experimental studies. A standardisation of key words on behalf of journal editors is proposed., (C) 1999 Elsevier Science Ltd. All rights reserved.
