Summary Comorbidity is common among cancer patients and increases with age. Comorbid conditions potentially affect treatment, therapy outcomes, and survival of people with cancer. This short review aims at presenting the prevalence of comorbidities, to illustrate their impact on elderly persons with cancer and to discuss their assessment.

The results of this study indicate that a combined exercise program significantly increases walking speed, absolute claudication distance, and muscle strength parameters. A greater benefit seems to result from a 12-month training program.

The exercise training achieved considerable effects on walking speed and claudication distance. Despite these improvements, patient's quality of life revealed no relevant change. This outcome could be explained by the fact that aspects of physical functioning relevant to patients with claudicatio intermittens may be underrepresented in the PLC-questionnaire core module.
