To the Editor: We would like to retract the article entitled “Gene Expression Signatures, Clinicopathological Features, and Individualized Therapy in Breast Cancer,” which was published in the April 2, 2008, issue of JAMA.1 A component of this article reported the use of chemotherapy sensitivity predictions based on an approach described by Potti et al in Nature Medicine in 2006. The Nature Medicine article was recently retracted due to an inability to reproduce the results with the chemotherapy signatures.2 Because a significant component of this JAMA article was based on the use of chemotherapy signatures reported in the Nature Medicine paper, we have decided to retract the JAMA article. We apologize for any negative impact on scientific research or clinical care caused by the publication of our article in JAMA.
