Abstract

Women with breast cancer (BC) experience multiple symptoms related to neoadjuvant chemotherapy (NAC) treatment that impair their functioning and quality of life (QoL). This study aimed to explore the effect of high-intensity aerobic interval training (HIIT) on quality of life and NAC side effects in women with BC.

Methods: 56 patients (48.56 (7.84) years, range 35-64 years) diagnosed locally advanced (stage II-III) ER + BC receiving doxorubicin/cyclophosphamide-based NAC were randomly assigned to the HIIT group and a control group (CG) for 6 months. The HIIT group performed 2 to 3 HIIT sessions per week according to the study protocol (4 × 4 minutes at 85%-95% peak heart rate (HR)). The CG followed the standard of care instructions by the oncologists. To assess the QoL participants completed the EORTC QLQ-C30 with the additional BC module of QLQ BR-23. Weekly self-reports on NAC side effects were collected through online survey.

Results: Study data were analyzed for 37 participants (nHIIT = 17, nCON = 20) who reported at least 14 (60%) weeks. HIIT was effective to reduce BC symptom scale outcomes (ES = 0.113, P = .048), and alleviate systemic therapy side effects (ES = 0.154, P = .020) and cancer related symptoms (ES = 0.124, P = .038). The most common side effect participants experienced at least 1 to 4 days/week was pain (average 50.9% and 56.8% for HIIT and CG, respectively), followed by sleep disturbances (average 50.9% and 49.9%, respectively). About 31% in both groups experienced sleep disturbances 5 to 7 days/week. The NAC induced physical, social and fatigue side effects had significantly lower incidence in HIIT group, while psychological side effects were significantly more common in training group.

Conclusions: HIIT is an effective physical exercise program to maintain higher quality of life and help to reduce some of NAC induced side effects for women with BC.
