title: Management of stage T3 and T4 glottic carcinomas.
abstract: Between 1959 and 1979, 242 patients with T3 and T4 lesions of the vocal cords were treated at our institution. Treatment consisted of total laryngectomy in all patients. Different modalities of regional node dissections were performed on 187 patients. In addition, 50 patients received irradiation with cobalt-60 postoperatively for specific features of the disease. In the group of 192 patients whose treatment consisted of surgery alone, 28 (14 percent) had recurrence in the neck and 10 (5 percent) had stomal recurrence. Of the patients treated with combined therapy, three (6 percent) had ipsilateral neck recurrences and one (2 percent) had stomal recurrence. For lesions staged N0, failure rates above the clavicles were 16 percent and 31 percent for patients with T3 and T4 lesions, respectively, in the group treated by surgery alone, 9 percent and 6 percent for patients with T3 and T4 lesions, respectively, in the combined therapy group. The rate of failure above the clavicles for lesions staged N+ was 32 percent in the group treated with surgery alone and 8 percent in the combined therapy group. In this study, a correlation was made between the failure rates above the clavicles and different clinical and histologic characteristics of the tumor, surgical findings, and the different modalities of cervical node dissection used. From analysis of the data, recommendations have been made for the selective treatment of patients with advanced glottic carcinomas.
