Since publication of the original article the authors noticed the affiliation for author G. Martinelli was incorrect. Their correct affiliation is Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) IRCCS, Meldola, Italy. This has now been corrected in the PDF and HTML versions of this article.
