We treated supraglottic squamous cell carcinoma (T1/2) with chemoradiation for laryngeal preservation and evaluated the effects of the chemoradiation at the dose of 40 Gy as an intermediate evaluation. To investigate the need for this intermediate evaluation, we retrospectively analyzed 46 patients, 43 men and 3 women aged 49 to 86 years, with supraglottic squamous cell carcinoma (T1/2) treated at our institution from January 1997 to May 2008. Overall and cause-specific three-year survival rates were 65% and 77% in all cases, 67% and 75% in T1, and 65% and 77% in T2. The three-year preservation rate of the larynx was 41% in all cases, 51% in T1, and 35% in T2. In the intermediate evaluation, the complete response rate was 58% in all cases, 77% in T1, and 48% in T2. In the cases of larynx preservation, the recurrence rate of the primary site was not significantly different between those cases who did not achieve complete response in the intermediate evaluation and those who did achieve complete response.
