Five-Year Impact Factor: 2010

The standard Impact Factor measures citations to journal articles published within a two-year period. The five-year Impact Factor evaluates citations to journal articles published within a five-year period to provide a measure of a journal's longer-term influence. AACR journals increased their rankings and are now all in the top 20 percent among oncology journals with respect to five-year Impact Factor. Cancer Research and Clinical Cancer Research ranked within the top 10 percent of the Oncology category.

   ^aCancer Epidemiology, Biomarkers & Prevention is also ranked in the Public, Environmental, and Occupational Health category in JCR.

Eigenfactor: 2010

The Eigenfactor uses methods from network theory to rank the influence of journals, much as Google's PageRank algorithm ranks the influence of web pages, by identifying journals as influential if they are cited often by other influential journals.

Four AACR journals are among the top 20 oncology journals as ranked by Eigenfactor — including Cancer Research, which holds the highest Eigenfactor ranking among all oncology journals.

   ^aCancer Epidemiology, Biomarkers & Prevention is also ranked in the Public, Environmental, and Occupational Health category in JCR.
