*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	28.298
Cancer Epidemiology, Biomarkers & Prevention	4.898
Cancer Immunology Research	9.876
Cancer Prevention Research	3.935
Cancer Research	9.883
Clinical Cancer Research	10.115
Molecular Cancer Research	4.760
Molecular Cancer Therapeutics	5.766

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	0.06928
Cancer Epidemiology, Biomarkers & Prevention*	0.02619
Cancer Immunology Research	0.02644
Cancer Prevention Research	0.00752
Cancer Research	0.11868
Clinical Cancer Research	0.13152
Molecular Cancer Research	0.01365
Molecular Cancer Therapeutics	0.02869

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	7.359
Cancer Epidemiology, Biomarkers & Prevention*	0.927
Cancer Immunology Research	1.736
Cancer Prevention Research	0.576
Cancer Research	2.246
Clinical Cancer Research	3.077
Molecular Cancer Research	1.356
Molecular Cancer Therapeutics	1.037
