There is a continuous publication output growth in the interdisciplinary field of individual quality of life of rectal cancer patients. The purpose of this scientometric investigation was to analyze the essential peculiarities of science stratification and the dynamic internationalization of research devoted to this socially significant topic.


In February, 2014, a retrospective problem-oriented search was performed in Web of Science (WoS) and MEDLINE (Thomson Reuters, USA) as well as in Scopus (Elsevier, the Netherlands) for a 20-year period (1994-2013). The following scientometric parameters were comparatively studied: number of abstracted publications; names and countries of authors; languages and types of primary documents; titles of journals and number of articles in them, and nominations and countries of authors' institutions. Citation analysis in WoS was performed, too.


In WoS, there were 1758 items by authors from 58 countries, in Scopus - 1835 by authors from 63 countries, while in MEDLINE - 1341 ones. Most papers were abstracted in 2013 (208 in WoS, 273 in Scopus and 124 in MEDLINE, respectively). On the other hand, only 15 papers were abstracted in 1995 in WoS, 24 - in 1994 in Scopus, and 22 - in 1995 in MEDLINE. Primary publications were in 9 languages in WoS, in 26 - in Scopus and in 23 - in MEDLINE. In WoS, there were 1351 original articles, 257 reviews, 192 proceeding papers, 26 editorials, 19 letters-to-the-editor, 87 meeting abstracts, and 31 book chapters. Some corresponding figures in Scopus were 1153, 449, 53, 54, and 50, respectively. In MEDLINE, there were 1292 original articles, 320 reviews, 110 case reports, 82 randomized controlled trials, 21 meta-analyses, 24 letters-to-the-editor, 18 editorials, etc. C. J. H. van de Velde presented with most publications in WoS, while V. Valentini did in Scopus. The journal Dis. Colon Rectum contained most papers abstracted in these data-bases. Next came several eminent journals such as Int. J. Radiat. Oncol. Biol. Phys., Colorectal Dis., Cancer Chemother., etc. The authors from the USA occupied the leading position followed by those from Germany, UK and Italy. The scientists at the Memorial Sloan-Kettering Cancer Center (USA) were most productive. The papers abstracted in WoS received 32567 citations of which, 26672 were without self-citations. There were 20300 citing articles, of which 19090 were without self-citations. Average citations per item were 18.53, average citations per year were 1550.81, and h-index was 77. These data testified to an intensive dissemination of new information among the researchers from different institutions and countries. There was an uninterrupted increase of the number of internationally co-authored publications. The paper by F. H. Schroeder et al. (N. Engl. J. Med., 360, 2009, No 13, 1320-1328) received 1424 citations in WoS.


Our results demonstrate that the files of abstracts and full-text papers identified by this scientometric constellation could be used for the promotion of the fruitful international collaboration of the scientists from smaller countries.
