title: The degree of extramural spread of T3 rectal cancer: a plea to the UICC and AJCC.
abstract: The above article, published online on 15 July 2016 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor-in-Chief, Neil Mortensen, and John Wiley & Sons Limited. After acceptance the authors were made aware of a contribution to a prior publication of the UICC, TNM Supplement: A commentary on uniform use, 4th Edition, ed. C. Wittekind (Wiley, 2012), p. 195, which renders the central argument of their article invalid. They have therefore asked for it to be withdrawn. A modified version of the paper was published in the January 2017 issue (volume 19; issue 1) with the title "The degree of extramural spread of T3 rectal cancer: an appeal to the American Joint Committee on Cancer".
