Resumen
Fecha de inicio: 1 de abril de 1996
Fecha en la que se inscribió al primer participante.OBJECTIVES: Compare the local response rate in patients with stage II invasive squamous cell carcinoma of the true vocal cord treated with hyperfractionation vs conventional fractionation radiotherapy. Compare the acute and late toxic effects of these regimens in this patient population. Compare the overall and disease-free survival patterns in this patient population treated with these regimens. OUTLINE: This is a randomized study. Patients are stratified according to substage (T2a vs T2b). Patients are randomized to 1 of 2 treatment arms. Arm I: Patients undergo conventional radiotherapy 5 days a week for 5 weeks followed by boost radiotherapy 5 days a week for 2 weeks. Arm II: Patients undergo hyperfractionation radiotherapy 5 days a week for 5 weeks followed by boost radiotherapy 5 days a week for 1.6 weeks. Patients with biopsy-proven persistent disease at least 6 weeks after completion of radiotherapy undergo salvage surgery with neck dissection (at the discretion of the surgeon). Patients are followed at 4 weeks, every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study within 3.2 years.
