Abstract: Background: There exists a lack of knowledge regarding the quantity
and quality of scientific yield in relation to individual cancer types. We aimed to
measure the proportion, quality and relevance of oncology-related articles, and
to relate this output to their associated disease burden. By incorporating the
impact factor(IF) and Eigenfactor (TM)(EF) into our analysis we also assessed
the relationship between these indices and the output under study.
Methods: All publications in 2007 were retrieved for the 26 most common
cancers. The top 20 journals ranked by IF and EF in general medicine and
oncology, and the presence of each malignancy within these titles was
analysed. Journals publishing most prolifically on each cancer were identified
and their impact assessed.
Principal Findings: 63260 (PubMed) and 126845 (WoS) entries were generated,
respectively. 26 neoplasms accounted for 25% of total output from the top
medical publications. 5 cancers dominated the first quartile of output in the top
oncology journals; breast, prostate, lung, and intestinal cancer, and leukaemia.
Journals associated with these cancers were associated with much higher IFs
and EFs than those journals associated with the other cancer types under
study, although these measures were not equivalent across all sub-specialties.
In addition, yield on each cancer was related to its disease burden as measured
by its incidence and prevalence.
Conclusions: Oncology enjoys disproportionate representation in the more
prestigious medical journals. 5 cancers dominate yield, although this attention
is justified given their associated disease burden. The commonly used IF and
the recently introduced EF do not correlate in the assessment of the
preeminent oncology journals, nor at the level of individual malignancies; there
is a need to delineate between proxy measures of quality and the relevance of
output when assessing its merit. These results raise significant questions
regarding the best method of assessment of research and scientific output in
the field of oncology.
