Abstract
In this study, 92 patients with supraglottic cancer during the last 10 years (28.5% of 323 laryngeal cancer cases) were investigated from clinical and pathological aspects, of the 92, 7 was in stage I, 29 in stage II and 56 was in stage III and IV.
Curative radiotherapy with the dosis over 60Gy was given in 41 cases (44.6%). Of the 41, 25 were in stage I or II and local recurrences were found in 5 cases (20.0%). They underwent total laryngectomy subsequently. The 10-year crude survival rate of curative radiotherapy was 83.3% in stage I, 89.5% in stage II and 18.8% in stage III and N. In 3 cases with T3N0M0 with vocal foldfixation, the tumor was completely cured with radiotherapy alone. Two of them had complete recovery of vocal fold movements, whereas. One kept having the vocal fold fixed without disease.
Among 37 supraglottic cancer cases who had bad cervical lymph node metastasis, any patient did not survive with the larynx conserved.
In supraglottic cancer cases, the depth of cancer invasion must be determined based on clinical examinations of the primary site before selection of the method of therapy.
