[Effectiveness of concomitant therapy with S-1, nedaplatin, and radiation for laryngeal cancer].

: Laryngeal cancer occurs more frequently in head and neck cancers, so there are a number of reports regarding the treatment results,wherein the therapeutic strategy and results are stable to some extent. However, due to the spread of chemoradiotherapy, there are differences in the larynx preservation rates for T2 and T3 cases, depending on the facility. Our department has been administering chemoradiotherapy for advanced cancer based on the perspective of conserving the organ and the function. We herein report our examination of 20 laryngeal cancer cases receiving concomitant therapy with S-1, Nedaplatin, and radiation (hereinafter, referred to as SN therapy) in our department from April 2005 to December 2008. The resulting complete response (CR) rate for the SN therapy was 82.4%, excluding T4 cases. Due to their refusal of surgery, 2 of 3 cases in which the SN therapy had been administered for T4 cases receiving SN therapy showed CR, wherein the CR rate in all cases after the SN therapy was 80. 0%. The larynx preservation rate after the SN therapy was 94.1%.
