JCO has confirmed once again its position as publisher of the most important clinical oncology research, with higher scores recorded in key measures of a journal’s impact on scientific literature.

As reported by Thomson Reuters in its 2010 Journal Citation Reports®:

• JCO’s impact factor has increased, for the sixth year in a row, to 18.970, ranking it fourth among 184 oncology journals surveyed.
• Total 2010 citations in scientific literature exceeded 114,000, ranking JCO second among oncology journals.
• JCO’s Eigenfactor* score—a measure of the Journal’s total influence on the research community—is the 17th highest among all 8,005 Scientific, Technical, and Medical (STM) journals included in the Reports.

*The Eigenfactor method considers the past five years’ Thomson Reuters journal-to-journal citation network, excluding self-citations, so that highly cited journals affect the score more than less-cited journals.
