Can a new questionnaire capture what metastatic breast cancer really feels like?
NCT ID NCT07806266
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
Researchers across Europe are developing a new questionnaire to better measure the quality of life of women with metastatic breast cancer, a cancer that has spread beyond the breast. The tool aims to capture issues that standard questionnaires miss, such as the impact of ongoing treatment and living with an advanced disease. Women aged 18 and older with this diagnosis will be interviewed to guide the questionnaire's design, ensuring it reflects real patient experiences. The goal is to give doctors a more precise way to assess and address what matters most to each patient.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a more accurate tool to measure how metastatic breast cancer affects daily life, helping tailor care to what matters most to patients.
- What could go wrong
- This is an early-stage development project, not a treatment test. The questionnaire may not capture all experiences or may need further validation before widespread use.
