*Blood Cancer Discovery, the latest AACR Journal, has 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.

Journal	Five-Year Impact Factor
Cancer Discovery	39.115
Cancer Epidemiology, Biomarkers & Prevention	5.730
Cancer Immunology Research	12.515
Cancer Prevention Research	4.543
Cancer Research	12.843
Clinical Cancer Research	12.836
Molecular Cancer Research	6.107
Molecular Cancer Therapeutics	7.019

Eigenfactor:

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.

Journal	Eigenfactor
Cancer Discovery	0.07246
Cancer Epidemiology, Biomarkers & Prevention*	0.02191
Cancer Immunology Research	0.02729
Cancer Prevention Research	0.00552
Cancer Research	0.10515
Clinical Cancer Research	0.13104
Molecular Cancer Research	0.01325
Molecular Cancer Therapeutics	0.02400

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.

Journal	Immediacy Index
Cancer Discovery	14.874
Cancer Epidemiology, Biomarkers & Prevention*	1.016
Cancer Immunology Research	3.264
Cancer Prevention Research	0.981
Cancer Research	2.731
Clinical Cancer Research	3.551
Molecular Cancer Research	1.890
Molecular Cancer Therapeutics	1.838
