Radical radiotherapy compared with surgery for advanced squamous cell carcinoma of the base of tongue.

Purpose: This study reports on T3/T4 base of tongue (BOT) tumors treated at the Erasmus MC (Rotterdam) with external beam radiotherapy (EBRT) and brachytherapy (BT). Local control, survival, and functional outcome are compared to results obtained in similar patients treated at the Vrije University Medical Center (VUMC, Amsterdam) by surgery and postoperative RT (PORT).
