title: [Thermoradiotherapy combined with daily administration of low dose cisplatin for locally advanced laryngeal carcinoma].
abstract: We applied thermoradiotherapy combined with daily administration of low dose cisplatin (CDDP) to five patients with locally advanced laryngeal carcinoma. The total response rate (CR + PR) was 100% after irradiation of 30 or 40 Gy. One case showed CR, and the larynx could be preserved by adding a full dose of irradiation. CDDP administration was discontinued in two cases due to renal dysfunction or thrombopenia, but other cases tolerated the therapy without severe side effects. Total laryngectomy and bilateral neck dissection was carried out in four cases after irradiation of 30 or 40 Gy. Removed larynxes were prepared for light microscopic observations of the serial sections. One of the four specimens revealed a CR histologically. The combination of thermoradiotherapy with low dose CDDP showed a remarkable effect on reduction of tumor size and cytotoxicity of tumor cells. This might contribute to saving the larynx of patients with locally advanced laryngeal carcinoma.
