Understanding how breast cancer treatment has evolved since 2008

This is a research study that gathers information from existing medical records of patients with metastatic breast cancer (cancer that has spread to other parts of the body) treated at 18 major cancer centers across France. The study looks at how doctors have treated this condition over the past 15+ years, tracking changes in chemotherapy, targeted therapy, immunotherapy, radiation, and hormone therapy. The goal is to understand real-world treatment patterns and outcomes to help improve future care.

Metastatic breast cancer treatment has changed significantly over the past decade with new medications and approaches becoming available. By studying actual patient records, researchers can see which treatments work best in real-world settings and identify gaps or improvements in how this disease is being managed.
