Predicting Breast Cancer Subtypes in BRCA-Associated HR+/HER2-Negative Disease

Official title: Prognostic and Predictive Role of Intrinsic Molecular Subtypes in BRCA-associated Breast Cancer

Run by University of Modena and Reggio Emilia · NCT07617025 · Data updated 2026-11-12

This study tests whether BRCA1/BRCA2-related, hormone-receptor–positive, HER2-negative breast cancers have distinct molecular subtypes that might respond differently to endocrine therapy or CDK4/6 inhibitors.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with BRCA1 or BRCA2 pathogenic variants and HR+/HER2-negative breast cancer who have available medical records and FFPE tumor tissue.

Probably not a fit

Patients without BRCA mutations or those lacking available tumor tissue or records may not benefit.

What this trial studies

This observational study collects existing clinical data and tissue samples from about 100 patients across several Italian hospitals. It aims to characterize intrinsic molecular subtypes of BRCA-associated HR+/HER2-negative breast cancer and see if these subtypes relate to treatment response and outcomes. No additional procedures beyond standard care are required, and FFPE tumor tissue is used for molecular analysis. The study compares cancers arising from BRCA1 versus BRCA2 mutations to explore potential differences in biology and prognosis.

Why it matters

Potential benefit: Understanding molecular subtypes could help tailor treatment choices and predict outcomes for BRCA-associated HR+/HER2-negative breast cancer.

How similar studies have gone: Previous studies suggest molecular subtypes influence response to therapy in BRCA-related cancers, but this study builds on that by focusing on HR+/HER2-negative cases.
