Hypofractionated Radiotherapy for T1N0M0 Glottic Cancer: Retrospective Analysis of Two Different Cohorts of Dose-fractionation Schedules from a Single Institution

Radical radiotherapy schedules incorporating a higher dose per fraction yield acceptable local control rates and late toxicity. Telecobalt therapy for early glottic cancer is a safe alternative to treatment with 6 MV photons on a linear accelerator in terms of local control and late toxicity as long as field sizes smaller than 36 cm2 are used.
