Fatigue (PDQ®): Supportive care - Health Professional Information [NCI] - Intervention
Table 2. Centrally Acting Stimulants for Adult Cancer Patients continued...
Exercise for patients with advanced or terminal disease is difficult to study but may yield similar benefits. The ability of patients with advanced cancer who are in hospice care and on a physical therapy regimen to carry out activities of daily living has been reported to improve in one study.[Level of evidence: III] Improved satisfaction with the physical therapy regimen was reported when family involvement in the program increased. A randomized study suggested that exercise improved fatigue during breast cancer treatment.[Level of evidence: I]
When educating patients about activity with respect to CRF, one important goal to consider is inclusion of 3 to 5 hours per week of moderate activity. It is critical that:
- Patients choose a type of exercise they enjoy.
- Providers discuss specific implementation strategies (type of exercise, time of day, days of the week, location of activity) to enable patients to make frequent activity a reality.
Beginning with lighter activity for shorter periods of time and building in intensity and length of time may be required. Studies have confirmed this can be safely done both during active treatment and after treatment is completed.
Variations of exercise that have a mind-body component include complementary modalities such as qigong, tai chi, and yoga, popular interventions that are being studied for their effects on CRF. These modalities are unique in that they incorporate cognitive and spiritual elements with movement, stretching, and balance. One fairly large study evaluated medical qigong for CRF in a heterogeneous group of 162 patients either undergoing cancer treatment or having finished cancer treatment. This study reported significant improvements in fatigue and several other aspects of quality of life for the intervention group versus usual care.
The qigong intervention was delivered in 90-minute group sessions twice a week for 10 weeks, for 1,800 minutes of treatment. The usual-care group did not receive any group meetings or additional provider interaction. It is therefore difficult to say what qigong uniquely provided over and above nonspecific or group-interaction effects. It is also not known how much survivors would need to continue performing qigong to maintain benefits. There were no adverse events in this study, so other than time and resource expenditure, it is difficult to pinpoint a downside to encouraging patients to adopt such an activity. One important strength of the study evaluating qigong was the collection of serum to measure markers of inflammation. At the end of 10 weeks, the C-reactive protein of patients in the medical qigong group decreased 3.6 mg/L, while patients in the usual-care group experienced an increase in this marker of 19.57 mg/L. This was a statistically significant difference.
