Multimodal prehabilitation combining exercise, nutrition, and psychological support to improve chemotherapy response in early breast cancer

Official title: Multimodal Intervention During Neoadjuvant Chemotherapy in Patients With Early-breast Cancer as a Strategy to Improve Treatment Response: DIANA Trial (Multimodal Prehabilitation: DIet, ANxiety Control Psychotherapy, Physical Activity)

Run by Hospital Clinic of Barcelona · NCT07107594 · Data updated 2026-11-12

This trial will try a combined program of exercise, nutrition, and psychological support during neoadjuvant chemotherapy to see if it improves tumor response in women with early-stage (I–III) breast cancer.

Is this trial a fit for you?

Likely a good fit

Adult women (≥18 years) with non-metastatic (stage I–III) breast cancer who are planned for neoadjuvant chemotherapy and are physically able to perform moderate-to-high intensity exercise.

Probably not a fit

Patients with metastatic (stage IV) disease, those unable to exercise safely, pregnant or breastfeeding women, men, or patients already doing more than 150 minutes per week of moderate-to-vigorous aerobic exercise are unlikely to benefit from this intervention.

What this trial studies

This randomized trial will enroll 214 women with non-metastatic (stage I–III) breast cancer who are scheduled for neoadjuvant chemotherapy and assign them 1:1 to either a multimodal prehabilitation program or standard care. The intervention group will receive structured physical exercise, nutritional guidance, and psychological support during the 4–6 months of chemotherapy, while the control group will receive routine clinical management. The primary comparison is the pathological response to chemotherapy at the time of surgery, with secondary outcomes likely including quality of life and treatment tolerance. The program seeks to optimize patients' physical and emotional condition and may favorably affect tumor microenvironment factors that influence treatment response.

Why it matters

Potential benefit: If successful, the program could increase rates of complete pathological response to neoadjuvant chemotherapy, potentially improving long-term outcomes and guiding postoperative treatment decisions.

How similar studies have gone: Individual components such as exercise, nutritional support, and psychological interventions have shown benefits for quality of life and treatment tolerance in breast cancer, but robust evidence that combined multimodal prehabilitation improves pathological chemotherapy response is limited.
