Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old with early-stage triple-negative breast cancer who require clips placed before neoadjuvant chemotherapy.
✕Probably not a fit
Patients who are pregnant or have a history of clinically active malignancy in the last 5 years may not benefit from this study.

What this trial studies
This observational study aims to establish a collection of ex vivo tumor organoids from patients with triple-negative breast cancer. By utilizing advanced 3D cell culture techniques, the study will create organoid models that closely mimic the original tumors, allowing for the evaluation of innovative therapies and the identification of predictive biomarkers for treatment response. The organoids will be derived from patients undergoing neoadjuvant chemotherapy and will be analyzed for their growth and response to various treatments.
Why it matters
Potential benefit: If successful, this study could lead to more effective treatment options and personalized therapies for patients with triple-negative breast cancer.
How similar studies have gone: While the use of organoids in cancer research is gaining traction, this specific approach to triple-negative breast cancer is relatively novel and has not been extensively tested in prior studies.
