Abstract Background Except for early T1 2 N0 stages the prognosis for patients with oral cavity cancer OCC is reported to be worse than for carcinoma in other sites of the head and neck HNC . The aim of this work was to assess disease outcome in OCC following IMRT. Between January 2002 and January 2007 346 HNC patients have been treated with curative intensity modulated radiation therapy IMRT at the Department of Radiation Oncology University Hospital Zurich. Fifty eight of these 16 were referred for postoperative 28 or definitive 30 radiation therapy of OCC. 40 of the 58 OCC patients 69 presented with locally advanced T3 4 or recurred lesions. Doses between 60 and 70 Gy were applied combined with simultaneous cisplatin based chemotherapy in 78 . Outcome analyses were performed using Kaplan Meier curves. In addition comparisons were performed between this IMRT OCC cohort
