Thirty percent of patients with head and neck cancer are over 70 years. Radiotherapy approach in elderly is a challenge. On one hand, radiotherapy side effects, as well as the number of sessions required, could be a burden. On the other hand, omission of local treatment is not an option due to the symptoms of the tumor. Patients in good general condition may receive standard fractionnated radiotherapy. For frail patients unsuitable for standard fractionated radiotherapy, more convenient shorter course of radiotherapy are commonly used. Physicians have to choose the best radiotherapy schedule according to the objective of the treatment. In case of palliative intend: hypofractionated radiotherapy delivered with a single short course could be recommanded. This course could be followed by other subsequent courses if the patient's condition improves during the treatment. For patients treated in curative intend, the choice of hypofractionation schedule depends on the general condition: split course hypofractionated radiotherapy for unfit patients, or accelerated radiotherapy with concomitant boost for fit patients. In all cases, a high-quality radiotherapy technique and appropriate supportive care are mandatory to minimize the side effects. The ELAN RT trial, soon to be completed, will rule on the non-inferiority of hypofractionated radiotherapy compared to standard radiotherapy for unfit patients.
