What this trial studies

This multicentric observational study investigates the role of selenoproteins as prognostic markers and potential therapeutic targets in breast cancer, specifically triple-negative breast cancer (TNBC). The study includes both retrospective and prospective components, where tissue microarrays will be prepared from surgical samples of TNBC patients, and plasma samples from healthy subjects and metastatic TNBC patients will be analyzed for selenoprotein expression using ELISA. The aim is to better understand the relationship between selenoproteins and breast cancer outcomes.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic tools and targeted therapies for patients with breast cancer.

How similar studies have gone: While the role of selenoproteins in cancer is being explored, this specific approach in TNBC is relatively novel and has not been extensively tested in prior studies.
