ESR1 Mutations in Metastatic Hormone Receptor‑Positive Breast Cancer in Greece
This study tests how common ESR1 mutations are in Greek patients with advanced hormone receptor–positive, HER2‑negative breast cancer and looks at how those mutations relate to disease features and real-world treatment patterns.
-
Personalized treatment after endocrine therapy failure in metastatic breast cancer
The study tests whether using a patient’s fresh tumor sample to try different drugs outside the body can help pick the next therapy for hormone receptor-positive, HER2-negative metastatic breast cancer that progressed on endocrine therapy.
-
Combination of Camizestrant and Ribociclib in HR+ Breast Cancer
This study tests whether the combo of camizestrant and ribociclib can help people with HR+ breast cancer who have already had endocrine therapy to delay disease progression.
