New Biomarkers in Metastatic Breast Cancer & Awareness on ESR1 and Liquid Biopsy: Analysis of a European Patient Survey
Publication format: White Paper
Year: 2025
Topic: Advocacy, Equity / Access, Policy & Regulation
Language: English
This White Paper, produced by Cancer Patients Europe, presents findings from a 1,268-respondent survey across France, Germany, Italy, Spain, and the UK focusing on metastatic breast cancer patients with ER+/HER2− disease. It reveals critical awareness gaps: 70% of target respondents were unaware of ESR1 mutations’ role in treatment resistance, and only 12% had been tested. The document issues a Call to Action to policymakers, healthcare professionals, and patient associations to improve access to ESR1 biomarker testing, liquid biopsy, and new targeted therapies across EU health systems.
