Characterizing breast stem and immune cells in early-stage breast cancer

Evaluation of Stem and Immune Cells in the Early Stage Breast Cancer Without Genetic Risk

Observational Centre Leon Berard · NCT03870802

This study looks at the breast stem and immune cells in women with early-stage breast cancer to see how they affect cancer growth and treatment, hoping to find new ways to help patients.

What this trial studies

This observational study focuses on adult women with early-stage breast cancer, specifically those with Luminal A or Luminal B tumors. It aims to quantitatively and qualitatively characterize the breast stem cells and immune system cells present in the mammary gland after solitary confinement. The study will analyze the tumor micro-environment and its impact on cancer progression and treatment efficacy. By understanding the role of these cells, the research seeks to identify potential biomarkers for breast cancer risk and develop new therapeutic strategies.

Who should consider this trial

Good fit: Ideal candidates are adult women aged 18 and older with early-stage breast cancer requiring total mastectomy, specifically those with Luminal A or Luminal B tumors.

Not a fit: Patients who have undergone prior anti-tumor treatments or those with chronic auto-immune diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of breast cancer progression and inform new treatment strategies.

How similar studies have performed: While this approach is novel in its specific focus on breast stem and immune cells, similar studies have shown promise in understanding tumor micro-environments.
