A survey of evidence in the Journal of Veterinary Internal Medicine oncology manuscripts from 1999 to 2007.
OBJECTIVE
To survey and monitor trends in evidence for oncology manuscripts published in the Journal of Veterinary Internal Medicine (JVIM) between 1999 and 2007 based on an evidence-based medicine (EBM) standard.


METHODS
All veterinary oncology-related articles published in JVIM and 7 other high-impact journals from 1999 to 2007 were collected by database searches. Relevant manuscripts then were characterized including investigator affiliation, subject matter investigated, retrospective or prospective study design, manuscript type, and classifications of manuscripts using an EBM standard.


RESULTS
A total of 172 relevant veterinary oncology manuscripts were identified in JVIM between 1999 and 2007. The proportion of oncology manuscripts published each year rose with the total number of manuscripts published in JVIM (mean, 13%; range, 8-15%). The author affiliations and subject matter were similar during this evaluation period. Case series represented the most common manuscript type (40%). With the exception of a progressive increase in prospective manuscripts and a reduction in case reports, no significant changes in the classification of manuscripts using EBM standards were seen. During this same period, veterinary oncology manuscripts published in 7 high-impact journals were associated with higher standards of evidence including prospective studies and randomized trials.


CONCLUSIONS
The standards of evidence for veterinary oncology manuscripts published in JVIM have remained static between 1999 and 2007. This survey provides an informative benchmark for the state of evidence in previous JVIM oncology manuscripts and may be useful in identifying specific opportunities that may raise the standards of evidence in future publications in JVIM.
