| Abstract: | Conclusion: It is important to prevent regional lymph node recurrence and distant metastasis to achieve better survival of laryngeal cancer. Objective: Therapeutic outcomes of 130 cases with laryngeal cancer treated at Kyoto University Hospital between 1995 and 2004 were reviewed. Patients and methods: In all, 121 males and 9 females were involved. Their ages ranged from 40 years to 92 years (average 66 years). All tumors were squamous cell carcinoma - arising at the glottis in 111 cases, the supraglottis in 18, and the subglottis in 1 case. Most glottic cancers (77.5%) were classified as stage I or II, while most supraglottic cancers (77.8%) were at stage III or IV. Stage I/II cancers were basically treated by conventional radiotherapy (60-66 Gy) and twice-daily hyperfractionated radiotherapy (70-74 Gy), respectively, attempting to preserve the larynx. Total laryngectomy with neck dissection was performed in the treatment of stage III/IV cases. Results: Five-year disease-specific survival rates were 100%, 96%, 100%, and 68% for stage I, II, III, and IV, respectively. Five-year laryngeal preservation rates were 98%, 100%, 86%, 0%, and 0% for T1a, T1b, T2, T3, and T4 of glottic cancer, respectively. Local recurrence occurred in five cases of stage I/II glottic cancer, which was successfully salvaged. Regional lymph node recurrence occurred in five cases including four patients with glottic cancer and one with supraglottic cancer. Two of them died of disease despite undergoing salvage therapy. Distant metastasis occurred in the lung in four cases including one glottic and three supraglottic cancer patients after initial treatment. [ABSTRACT FROM AUTHOR] |
