In the Review article published in the April issue of Nature Reviews Clinical Oncology there were errors in the clinical data presented in Tables 1 and 2. In addition, the primary end point of the adjuvant AVANT and NSABP-C-08 trials should have been disease-free survival (DFS) instead of progression-free survival (PFS). The errors have been corrected for the HTML and PDF versions of the article.
