Trial to Investigate Exercise with Neodjuvant Chemotherapy for Breast Cancer
The prognosis for breast cancer has improved, allowing more and more women to be cured with a combination of surgery, radiotherapy and medical treatment. A new trial led by Karolinska Institutet will investigate whether combining neoadjuvant chemotherapy with exercise will improve the outcomes of breast cancer patients.
Neoadjuvant chemotherapy (NACT) is increasingly used in breast cancer. The main benefit of NACT is its ability to downstage large tumours with a view to treatment by breast-conserving surgery, although there is a non-significant increase in the local recurrence rate. The best proof of NACT efficacy is pathological complete response (pCR), ie the absence of invasive tumour on post-NACT on surgical histopathology.
“While it is known that physical exercise can help patients to better tolerate 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”, explained Jana de Boniface, principal investigator of the trial and associate professor in the Breast Surgery Group, Department of Molecular Medicine and Surgery.
The Neo-ACT trial opened for recruitment in September 2022, and it is estimated that inclusion may be completed in December 2025.
