Our system for collecting declarations of competing interests failed partially for this editorial by J M Dixon and G Hortobagyi (19 February, pp 457-8). Because the BMJfailed to send Dr Hortobagyi a form, we did not receive a statement on competing interests from him. His coauthor, however, did receive a form and stated “none declared.” We now have a statement from Dr Hortobagyi (see below). We apologise to him and to readers for our oversight.
