Patients over 65Â years are assigned lower ECOG PS scores than younger patients, although objectively measured physical activity is no different

PA levels were low, but PS scoring reflected relative PA levels and differentiated between patients of PS 0 and 2-3. Chronological age was not predictive of activity levels, but older patients were assigned lower PS scores. Incorporation of objective PA measures may merit further investigation especially in the geriatric oncology setting.
