Background:
The objective of this study was to report our experience in the management of patients with advanced-stage supraglottic laryngeal carcinoma and to identify factors predictive of outcome.
Methods:
In total, 181 patients with advanced-stage supraglottic laryngeal carcinoma were treated at Memorial Sloan-Kettering Cancer Center between 1984 and 1998. Sixty-nine (38%) patients were treated by surgery +/- postoperative radiotherapy (SRT), 93 (52%) by chemoradiotherapy (CTRT), and 19 (10%) by radiotherapy alone (RT). Survival outcomes were calculated using the Kaplan-Meier method. Predictors of outcome were identified using multivariate analysis.
Results:
The-5 year overall survival (OS) and disease-specific survival (DSS) were 53% and 71%, respectively. Patients treated with SRT and CTRT had comparable outcomes. The main independent predictors of OS and DSS were age greater than 60 years and stage of the neck at presentation.
Conclusion:
Regardless of index treatment, age over 60 years and clinical stage of the neck at presentation were the main independent predictors of OS and DSS.
