Purpose:
Chemotherapy-related cognitive impairment (CRCI) is a prevalent neurotoxicity in patients with breast cancer (BC), leading to cognitive decline and reduced quality of life. Exercise is recommended as a potential strategy to mitigate CRCI; however, optimal exercise modalities and protocols remain unclear. Moreover, implementing exercise during chemotherapy presents practical and adherence challenges, highlighting the need for feasible, targeted exercise interventions. This study aimed to evaluate the effects of an aerobic exercise programme delivered throughout chemotherapy on cognitive function in patients with BC.
Methods:
A non-randomized controlled clinical trial was conducted in patients aged 18-65 years with stage I-III breast cancer undergoing chemotherapy. Participants received either usual care or an aerobic exercise-based programme delivered throughout chemotherapy, incorporating behavioural and social support components. Subjective and objective cognitive function, fatigue, quality of life, and physical fitness were assessed at baseline, mid-chemotherapy, and post-intervention.
Results:
Fifty-nine patients (intervention group, n = 28 vs. control group, n = 31) were enrolled into the study, and 48 (24 per group) completed all tests at final-chemotherapy. Compared with the control group, significant improvements were observed in all measurements of cognitive function, fatigue, quality of life, and grip strength (healthy) after the intervention (p < .05).
Conclusion:
The aerobic exercise-based program had beneficial effects on cognitive function, fatigue, quality of life, and grip strength.
