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

Abstract

OBJECTIVE:

Several clinical trials examining treatment strategies for advanced laryngeal cancer have demonstrated that concurrent chemoradiotherapy is the most effective treatment for improving the patient response to radiotherapy and laryngeal preservation. We evaluated a new regimen of S-1/CDGP(Nedaplatin) with radiotherapy (RT), and established that it represented an effective new treatment option that allowed for the preservation of the larynx.

METHODS:

A total of 16 patients with stage II to IV laryngeal cancer(excluding T4 stage)who had been treated at our institution from 2001 to 2007 were recruited for the present study. All patients had histologically-confirmed squamous cell carcinomas.

RESULTS:

The administration of S-1/CDGP/RT led to a complete response (CCR) in all patients with stage II or IV disease, with preservation of the larynx in all of these cases. For patients with stage III disease, 6 (85%) experienced CR, and 1 patient (15%) had a partial response. The laryngeal preservation rate for these patients was 85%. Severe toxicities, i. e., neutropenia, thrombocytopenia, and dermatitis of grade 3, were observed. The overall five-year survival rate was 72%, and the disease specific survival rate was 92%.
