AIM To analyze scientometrically the dynamic science internationalization on colorectal tumour markers as reflected in five information portals and to outline the significant journals, scientists and institutions.METHODS A retrospective problem-oriented search was performed in Web of Science Core Collection(Wo S), MEDLINE, BIOSIS Citation Index(BIOSIS) and Scopus for 1986-2015 as well as in Dervent Innovations Index(Derwent) for 1995-2015. Several specific scientometric parameters of the publication output and citation activity were comparatively analyzed. The following scientometric parameters were analyzed:(1) annual dynamics of publications;(2) scientific institutions;(3) journals;(4) authors;(5) scientific forums;(6) patents-number of patents, names and countries of inventors, and(7) citations(number of citations to publications by single authors received in WoS, BIOSIS Citation Index and Scopus).RESULTS There is a trend towards increasing publication output on colorectal tumour markers worldwide along with high citation rates. Authors from 70 countries have published their research results in journals and conference proceedings in 21 languages. There is considerable country stratification similar to that in most systematic investigations. The information provided to end users and scientometricians varies between these data-bases in terms of most parameters due to different journal coverage, indexing systems and editorial policy. The lists of the so-called "core" journals and most productive authors in Wo S, BIOSIS, MEDLINE and Scopus along with the list of the most productive authors-inventors in Derwent present a particular interest to the beginners in the field, the institutional and national science managers and the journal editorial board members. The role of the purposeful assessment of scientific forums and patents is emphasized. CONCLUSION Our results along with this problem-oriented collection containing the researchers' names, addresses and publications could contribute to a more effective internati
