The role of behavioural modification and exercise in the management of cancer-related fatigue to reduce its impact during and after cancer treatment.

BACKGROUND: Fatigue is a symptom that can occur during treatment as an acute side effect but can also result in persistent fatigue as a long-term side effect or late effect. MATERIALS AND METHODS: We undertook a narrative review of the current literature and discuss the current evidence of assessment of fatigue and we specifically focus on the role of promoting behavioural change and focused rehabilitation to minimise these long-term effects and update the literature relating to this area from 2012 to date. RESULTS: We suggest there are behavioural change models that can be scaled up to enable patients to manage long-term fatigue using exercise. However, from this updated review there are limitations to the current infrastructure and evidence base that will impact on the ability to do this. CONCLUSION: We continually need to raise awareness amongst health professionals to continue to suggest modifications to impact on fatigue at all stages of cancer treatment and into survivorship and late effects. These can range from simple brief interventions suggested in the clinic to full scale rehabilitation programmes if the correct infrastructure is available. Whichever approach is adopted we suggest exercise will be the mainstay of the treatment of fatigue in this group
