What this trial studies

This observational study aims to create a repository of breast tumor tissue collected from core biopsies at the University of Southern California's Norris Comprehensive Cancer Center. The study will gather baseline and follow-up samples from patients with newly diagnosed breast cancer, allowing researchers to analyze tumor biology, proteins, and genes. The collected data will also include demographic and clinical information to support future research on breast cancer treatment and outcomes. The repository will facilitate the distribution of de-identified samples for various breast cancer-related studies.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of breast cancer biology and the development of better therapies and diagnostic tests.

How similar studies have gone: Other studies have successfully established tissue repositories for cancer research, indicating a promising approach for advancing breast cancer understanding.
