Developing organoids from breast cancer tissue

Developing Breast (Cancer) Organoids

Observational Maastricht Radiation Oncology · NCT05317221

This study is trying to create mini versions of breast cancer tumors from patient samples to see how they can help doctors understand the disease better and choose the best treatments for each person.

What this trial studies

This observational study aims to create a living biobank of breast cancer organoids derived from patient tissue samples collected during routine surgical procedures. By obtaining small samples of excised tumors and blood for genetic analysis, the study seeks to understand how these organoids reflect disease progression, treatment response, and relapse across different breast cancer subtypes. The goal is to develop a patient-tailored clinical model that addresses tumor heterogeneity and guides individualized treatment selection without altering the standard care process for participants.

Who should consider this trial

Good fit: Ideal candidates are female patients over 18 years old with a confirmed diagnosis of breast cancer who are undergoing primary surgery.

Not a fit: Patients who are physically or mentally incapable of providing informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective treatment strategies for breast cancer patients.

How similar studies have performed: Other studies have shown promise in using organoids for drug response screening, indicating potential success for this approach.
