[Efficacy of concurrent chemoradiotherapy with S-1 plus nedaplatin for hypopharyngeal cancer].

Many reports have been published on the treatment for hypopharyngeal cancer, and the treatment modalities and results have become uniform to some extent. More specifically, reconstruction by means of free jejunal grafts has become widespread, and the results of surgical treatments have stabilized. On the other hand concurrent chemoradiotherapy has been widely performed, and the results from the standpoint of organ and function preservation have revealed the various differences between institutions. In our department, we have been using concurrent chemoradiotherapy for advanced cancer with a view to organ and function preservation. In this article, we report 6 cases with hypopharyngeal cancer treated by concurrent chemoradiotherapy with S-1 plus nedaplatin(SN therapy)in our department between January 2005 and December 2008. The complete response rate after SN therapy was 83. 3%, and the laryngeal preservation rate was 100%.
