Exercise program aims to fight 'Chemo Brain' in Long-Term survivors
NCT ID NCT06925529
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 6-month supervised exercise program can improve blood flow to the brain and thinking skills in women who had breast cancer 5-10 years ago. Participants will be randomly assigned to either the exercise program or usual care. The goal is to see if exercise can reduce the risk of heart and brain problems that often follow cancer treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Exercise training program (Cardio-Oncology Rehabilitation and Exercise Programme)
- What this could lead to
- If it works, this could show that a structured exercise program helps protect brain function and reduce cognitive decline in breast cancer survivors.
- What could go wrong
- This is a small early-stage trial with only 40 participants, so results may not apply to all survivors. The exercise program requires commitment and may not be feasible for everyone.

Inclusion Criteria: * Female * Aged 45 - 75 years old at study enrolment * Diagnosed with stage 1 - 3 breast cancer 5 - 10 years prior to study enrolment * Have received potentially toxic chemotherapy, including: * Anthracycline (any dose) * Trastuzumab (Herceptin) in breast-cancer with the HER2 mutation OR * Tyrosine kinase inhibitors (e.g. sunitinib) OR * Left chest radiotherapy * ≥ 1 'traditional' CVD risk factor (I.e., Hypertension, dyslipidaemia, diabetes, obesity, smoking or family history of CVD) (Mehta et al., 2023) * 'Physically inactive', not meeting Australian physical activity guidelines for adults or regularly participating in structured exercise training (Care, 2024). * Eligible for Medicare * Willing to provide written informed consent to participate in the study Exclusion Criteria: * Diagnosed CVD or stage B heart failure * Diagnosed neurocognitive or cerebrovascular disease * Diagnosed atrial fibrillation or cardiac arrythmia * BMI ≤ 18.4 kg∙m2 * Any other contraindications to exercise testing and training that make participation in this study unsafe, determined through medical screening * Unable to speak and understand the English language * Contraindication to brain MRI * Participating in another clinical research trial where randomized treatment would be unacceptable * Oncologic (or other) life expectancy ≤ 12 months or any other medical condition (including pregnancy) that results in the belief (deemed by the Principal Investigator) that it is not appropriate for the patient to participate in this trial.
