Tracking retractions as a window into the scientific process

A fifth retraction for Anil Potti, this one in Blood

with one comment

The list of papers retracted by former Duke oncologist Anil Potti has grown to five. The notice, from Blood:

RETRACTION: Potti A, Bild A, Dressman HK, Lewis DA, Nevins JR, Ortel TL. Gene-expression patterns predict phenotypes of immune-mediated thrombosis. Blood. 2006;107(4):1391-1396.

The authors retract the 15 February 2006 paper cited above because they have been unable to reproduce the results that were performed independently by the first author, Anil Potti, regarding validation of predictive models for thrombotic phenotypes. It has also been recognized that multiple samples appear to be duplicated in the training and validation datasets pertaining to the analysis presented in Figure 2 of the paper, which was also performed by Anil Potti. Since these results are fundamental to the conclusions of the paper, the authors formally retract the paper. The authors deeply regret the impact of this action on the work of other investigators and apologize to the readers, reviewers, and editors of Blood.

Submitted August 19, 2011.

Accepted August 19, 2011.

The Blood paper has been cited 24 times, according to Thomson Scientific’s Web of Knowledge. The retraction joins others from the Journal of Clinical Oncology, Nature Medicine, The Lancet Oncology, and the New England Journal of Medicine.

Potti is now practicing oncology in South Carolina.

  1. Does Anil Potti have any papers left? Just retract them all.
