| Popis: | One hundred and twenty patients with early glottic carcinoma received radiation therapy at the University of Maryland Hospital from 1959 to 1977. The radiation dose ranged from 55 Gy in 4 weeks for small T1a lesions to 65 Gy in 61/2 weeks for T2 lesions. The local control rates by irradiation alone for stages T1a, T1b, and T2 were 92, 91 and 88 per cent, respectively, while 5-year determinate disease-free survival rates were 96 per cent for stage I disease and 88 per cent for stage II disease. Most of the local failures were salvaged by surgery, with a low complication rate. Regional metastases were uncommon, and occurred in 7 per cent in stage I and in 6 per cent in stage II disease. Factors increasing the risk of failures appeared to be bulky tumor, anterior commissure involvement and subglottic extension. |
