Lack of accountability in upholding authorship standards in prominent medical oncology clinical trials.

Authorship in biomedical publications is critical for establishing accountability and contribution toward clinical and scientific research. We examined the frequency of discordance in authorship between presentations of clinical trial data at annual meetings of the American Society of Clinical Oncology and the subsequent peer-reviewed publications. We found that more than 70% of subsequent publications had additional authors not originally present on the abstract despite there being no changes in trial accrual or trial design. This pervasive discordance in authorship demonstrates a lack of uniformity and accountability in authorship reporting standards.
