What this trial studies

This study aims to collect biological samples from women with localized or metastatic breast cancer to analyze their immune responses based on the type of systemic treatment they receive. It focuses on understanding how different treatments affect the immune system before and during therapy. Blood samples will be taken to evaluate the immune response and its evolution throughout the treatment process.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 85 with histologically proven infiltrating breast cancer, specifically those with triple negative or certain hormone receptor-positive subtypes receiving specific systemic treatments.

Not a fit: Patients with non-infiltrating breast cancer or those not receiving the specified systemic treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of how breast cancer treatments influence immune responses, potentially guiding more effective therapies.

How similar studies have performed: Other studies have shown promise in understanding immune responses in cancer treatment, suggesting that this approach could yield valuable insights.
