title: World gynecologic oncology publications and the Turkish contribution to the literature between 2000 and 2007.
abstract: OBJECTIVE
  To investigate the number of publications and the contribution from top-ranking countries, institutions, and authors in 3 gynecologic oncology journals (Gynecologic Oncology [GO], International Journal of Gynecological Cancer [IJGC], and European Journal of Gynaecological Oncology [EJGO]),as well as the degree of Turkish contribution between 2000 and 2007.
  
  
  METHODS
  Articles published between 2000 and 2007 in 3 gynecologic oncology journals indexed by the Science Citation Index were accessed via the ISI-Thomson website. Additionally, PubMed, Sciencedirect, and Blackwell-Synergy databases were used to identify the originating countries and institutions of the published articles. The types of articles, originating countries, and names of the institutions and authors were determined. Furthermore, the number of articles affiliated with Turkish institutions and the publication year were also determined.
  
  
  RESULTS
  We located 6,851 articles published in the 3 journals. During this period 36.1%, 7.7%, 7.2%, 5.8% and 4.8% of the papers originated from the USA, Japan, Italy, Turkey, and England, respectively. The 5 most productive institutions were the University of Texas, Memorial Sloan-Kettering Cancer Center, Roswell Park Cancer Institute, University of Alabama, and University of Athens. The 5 most productive authors were Markman (USA), Chi (USA), Ayhan (Turkey), Barakat (USA), and Vergote (Belgium), respectively. In all, 36.1% of the papers originated from the USA, while 44% originated from 17 European countries. The USA was the first-ranked country of origin in GO and IJGC, while Turkey was the first-ranked country of origin in EJGO. Overall, 399 (5.8%) papers originated from Turkish institutions.
  
  
  CONCLUSIONS
  Most of the gynecologic oncology publications originated from the USA and Western European countries, where gynecologic oncology training is available and surgical and research traditions are well established. On the other hand, Turkish researchers made an important contribution to gynecologic oncology research during the selected period of time; publications originating from Turkey exceeded in number all European countries, except those originating from Italy.
