INTRODUCTION: In our study, we have treated cases of early glottic carcinoma by two different dose-fractionation schedules in relation to overall treatment time. MATERIALS AND METHODS: This is an analysis of 29 patients with invasive, previously untreated T1and T2squamous cell carcinoma of true vocal cord that was treated by radical radiation therapy. DOSE AND FRACTIONATION: All patients were treated with a continuous course of radiation therapy with once-daily fractionation. All the patients were treated 5 days a week from Monday to Friday. The fractionation regime was either: (1) 62.5 Gy/25fractions/5 weeks at 2.5 Gy fractions (Regimen 1), (2) 70 Gy/35 fractions/7 weeks at 2 Gy/fraction (Regimen 2). Regimen 1 included 15/29 patients (51.72%) and Regimen 2 included 14/29 patients (48.27%). Patients were evaluated for: (1) Locoregional control, (2) acute and late radiation toxicities, (3) quality of voice. RESULTS AND OBSERVATION: There was no significant difference in terms of locoregional control rate, acute and late radiation toxicities in both groups. Voice quality during and after radiation was comparable in both arms. CONCLUSION: Use of high dose per fraction schedule with shorter duration of treatment results in comparable local control as well as the quality of voice to the protracted course of radiotherapy without increase in treatment-related toxicities. Shorter overall treatment time can be of great advantage in terms of time, cost, comfort, and acceptability by the patients.
