Impact Factor:

According to the Journal Citation ReportsTM (JCR) from ClarivateTM, 2022, Impact Factors for the AACR Journals:


Impact Factor

 Cancer Discovery 38.272
 Cancer Epidemiology, Biomarkers & Prevention 4.090
 Cancer Immunology Research 12.020
 Cancer Prevention Research 3.296
 Cancer Research 13.312
 Clinical Cancer Research 13.801
 Molecular Cancer Research 6.333
 Molecular Cancer Therapeutics 6.009
*Blood Cancer Discovery and Cancer Research Communications have not published long enough to have received an Impact Factor.


Five-Year Impact Factor:

While the standard Impact Factor measures citations to journal articles published within a 2-year period, the 5-year Impact Factor evaluates citations to journal articles published within a 5-year period to provide a measure of a journal's longer-term influence.


Impact Factor

 Cancer Discovery 41.226
 Cancer Epidemiology, Biomarkers & Prevention 5.594
 Cancer Immunology Research 13.345
 Cancer Prevention Research 4.317
 Cancer Research 13.678
 Clinical Cancer Research 13.975
 Molecular Cancer Research 6.750
 Molecular Cancer Therapeutics 7.059



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.



 Cancer Discovery 0.06475

Immediacy Index:

An Immediacy Index is a measure of how topical and urgent work published in a scientific journal is. The Immediacy Index is calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year.


Immediacy Index

 Cancer Discovery 8.337
 Cancer Epidemiology, Biomarkers & Prevention 1.068
 Cancer Immunology Research 2.297
 Cancer Prevention Research 1.000
 Cancer Research 2.876
 Clinical Cancer Research 3.545
 Molecular Cancer Research 1.414
 Molecular Cancer Therapeutics 1.583
