Using organoids to test chemotherapy sensitivity in breast cancer patients

Official title: Consistency of Organoids Based Drug Sensitivity and Efficacy of Neoadjuvant Chemotherapy in Breast Cancer

Run by Second Affiliated Hospital, Zhejiang University, School of Medicine · NCT06155305 · Data updated 2026-11-12

This study is testing if lab-grown mini tumors from breast cancer patients can help predict how well they will respond to chemotherapy before treatment starts.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are female patients aged 18 to 70 with early-stage breast cancer eligible for neoadjuvant chemotherapy.

Probably not a fit

Patients with locally advanced or inflammatory breast cancer, or those who have received prior treatments, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate the sensitivity of neoadjuvant chemotherapy in early-stage breast cancer patients by utilizing patient-derived organoids (PDOs). A total of 58 female patients, aged 18 to 70, will be recruited and their tumor biopsies will be cultured to create organoids. These organoids will be treated with standard chemotherapy drugs, and their growth will be assessed to determine treatment efficacy. The study will also correlate the organoid responses with clinical outcomes using the Residual Cancer Burden (RCB) system to enhance understanding of individual treatment responses.

Why it matters

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

How similar studies have gone: While the use of organoids in drug sensitivity testing is gaining traction, this specific application in neoadjuvant chemotherapy for breast cancer is relatively novel.
