title: Clinical target volume definition in the elderly patient.
abstract: Elderly age is one of the main risk factors to be associated with the onset of different tumors. The tumor in the elderly almost always appears at a late, advanced stage for the lack of an accurate attention to symptoms-signs, as well as for the absence of involvement in mass screening campaigns. In the choice of a radiotherapy treatment in the elderly, the healthy tissues adjacent to the tumor may show a different ability for repair; this should be kept in mind in the definition of the target volume together with the possible presence of comorbidities specific to the elderly age.
