Two hundred and ten patients with laryngeal cancer were treated at Oita Medical University Hos-pital over a 13 year period between October 1982 and October 1994. The male/female ratio was about 13 : 1. One hundred and fifty-three (68.1%) patients were diagnosed as having glottic cancer, 60 (28.6%) were as having supraglottic cancer, and the remaining 7 (3.3%) as having subglottic cancer.<BR>According to the UICC TNM classification system 1978, 76 patients (36.2%) were stage I, 45 (21.4%) were stage II, 55 (26.2%) were stage III and 34 (16.2%) were staze IV.<BR>Partial-laryngectomy was performed after 30 Gy irradiation for 67 out of 101 (66.3%) patients with early glottic cancer in order to dissect tumor more radicaly and to preserve their phonatial function. The recurrent ratio in patients that received a partial-laryngectomy (8.4%) was slightly lower (11.4%) than that in patients that received irradiation of only 50 Gy.<BR>The five-year survival rate was 68.7% in patients with larvnaeal cancer (stage I, 80.0%; stage II, 76.7%; stage III, 59.9%; stage IV, 53.4%), 78.4% in patients with glottic cancer, 52.1% in patients with supraglottic cancer, and 80.0% in patients with subglottic cancer.
