What this trial studies

This multicenter clinical trial aims to assess the prognostic significance of circulating tumor cells (CTCs) in female breast cancer patients who have undergone neoadjuvant treatment followed by surgery. Utilizing the GILUPI CellCollector®, the study will collect and analyze CTCs to determine their potential role in predicting patient outcomes. Participants must have completed their treatment within four years prior to enrollment and meet specific eligibility criteria related to their cancer stage and overall health.

Who should consider this trial

Good fit: Ideal candidates for this study are females aged 18 to 70 with histologically confirmed invasive breast cancer who have completed neoadjuvant treatment and surgery.

Not a fit: Patients with metastatic breast cancer or those who are pregnant or lactating will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the prognostic value of CTCs, potentially leading to improved monitoring and treatment strategies for breast cancer patients.

How similar studies have performed: While the use of CTCs in cancer prognosis is a growing field, this specific approach using the GILUPI CellCollector® is relatively novel and has not been extensively tested in similar studies.
