Elderly patients represent the most rapidly growing subgroup of the patient population in France and in the majority of industrialized countries. The effect of age in terms of the prognosis and response to treatment remains unclear. The management strategy (curative versus palliative) for head and neck cancer in the elderly has given vent to divergent opinions and controversies in several respects (the type and quality of treatment, quality of life and economic consequences). This review only focuses on the radiotherapy schedule and head and neck cancers. We compare aged patients with head and neck cancer to younger patients in terms of clinical features, tumor biology, type of treatment, side effects and response. We conclude that if the patient is in a good general condition following a complete evaluation of the cancer, physicians should propose curative treatment with radiotherapy because retrospective trials demonstrate that response in older patients when treated aggressively is comparable to that of younger patients. However, specific trials concerning aged patients with head and neck cancer, quality of life and radiotherapy are warranted.
