Study Overview
Brief Summary
Studies suggest that patients with hematological malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at risk for cognitive decline and long-term cognitive dysfunction. To address this issue, a randomized controlled intervention trial on the effect of physical exercise on cognition is conducted. In addition, the impact on psychological and physical health outcomes is evaluated. Results may benefit patients who suffer from disease- or treatment-associated cognitive change.
Detailed Description
Studies suggest that patients with hematological malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at risk for cognitive decline and long-term cognitive dysfunction. To address this issue, a randomized controlled intervention trial on the effect of physical exercise on cognition is conducted. In addition, the impact on psychological and physical health outcomes such as depression, fatigue, health-related quality of life and physical fitness is evaluated. A healthy control group matched to the patients on age, gender, and education will be included to both control for practice effects on neuropsychological measures and allow additional comparisons on self-report measures. The healthy control group will undergo neuropsychological testing and questionnaire survey at baseline and 4 months. Demographic data will be collected from all study participants at baseline. Medical data will be collected from patients at all time points. Results may benefit patients who suffer from disease- or treatment-associated cognitive change.

Arms & Interventions
Exercise group
The exercise program will be developed through a pilot phase with 10 patients prior to the start of the main study.
Intervention: Exercise (Behavioral)
Control group
A waitlist control group will get the intervention after 7 month of treatment as usual.
Intervention: Control (Behavioral)
Outcomes
Primary Outcomes
Change in cognitive functioning as assessed by Change in total z-score
Time Frame: Baseline and 4 months
Change in total z-score derived from a neuropsychological test battery (TMT-A, TMT-B, subtests Alertness, Sustained Attention and Flexibility from the German TAP, German Version of the Rey Auditory Verbal Learning Test, Digit Span from the WAIS-IV, German Version of the COWA, Tower of London).
Secondary Outcomes
- Change in depressive symptoms(Baseline, 4 months, 7 months)
- Change in physical ability/capability (walking ability)(Baseline, 4 months, 7 months)
- Change in cognitive functioning as assessed by Change in total z-score(Baseline and 7 months)
- Change in fine-motor function(Baseline, 4 months, 7 months)
- Change in immunological functions(Baseline, 4 months, 7 months)
- Change in physical fitness (muscle strength)(Baseline, 4 months, 7 months)
- Change in self-reported physical activity(Baseline, 4 months, 7 months)
- Change in fatigue(Baseline, 4 months, 7 months)
- Change in anxiety(Baseline, 4 months, 7 months)
- Change in self-reported cognitive functioning as assessed by Change in scale sum score (composite score) of the FEDA and FLei questionnaires(Baseline, 4 months, 7 months)
- Change in physical activity (intensity)(Baseline, 7 months)
- Change in health-related quality of life(Baseline, 4 months, 7 months)
- Change in fear of cancer recurrence(Baseline, 4 months, 7 months)
