In the article titled “Prognostic Role of Serum Amino Acids in Head and Neck Cancer” [1], authors Carlo Chiarla and Ivo Giovannini were affiliated to “Sezione di Igiene, Dipartimento Universitario di Scienze della Vita e Sanità Pubblica, Università Cattolica del Sacro Cuore, Rome, Italy” which is incorrect. The correct affiliation for both aforementioned authors is “CNR-IASI Centro di Studio per la Fisiopatologia dello Shock e Biomatematica, Università Cattolica del Sacro Cuore, Rome, Italy.” This has now been corrected in the author and affiliation details shown above.

The error was introduced during the production process of the article, and Hindawi apologises for causing this error.
