Summary
Brief summary
Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer. The best proof of NACT
efficacy is pathological complete response (pCR), i.e. the absence of invasive tumour on
post-NACT surgical histopathology. While it is known that physical exercise can help patients
to better tolerate and complete often harsh cancer treatments, it is an emerging area of
research to understand if and how exercise exerts anti-tumour effects and improves
oncological outcomes.

The main aim of the Neo-ACT trial is to examine if a physical exercise intervention during
NACT can increase pCR rates in breast cancer. Secondary aims are residual cancer burden,
radiological tumour response, patient-related outcomes (health-related quality of life,
physical activity), physiological outcomes (muscle strength, cardiorespiratory fitness),
cancer treatment-related toxicities (cognitive dysfunction, chemotherapy completion rates)
and long-term sick leave. Furthermore, the trial will explore how physical exercise affects
anti-tumoral mechanisms inherent to therapy or host by hypothesis-generating translational
analyses.

712 patients with primary invasive breast cancer will be randomized to either a supervised
intervention of high-intensity interval and resistance training during NACT, supported by an
exercise app, or to usual care, and followed for two years. Physical activity is meticulously
tracked. By offering patients active involvement, the trial contributes strongly to the
concept of personalized medicine.
