About this study

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

Breast cancer is the most common malignancy in women worldwide. Patients with breast cancer are often diagnosed at later stages and have a strong desire for breast conservation, necessitating neoadjuvant chemotherapy. Tumors of different molecular subtypes and individual variations among patients lead to significant differences in treatment efficacy. Precise assessment of patients' responses to treatment regimens is imperative in advancing prognosis of breast cancer. In this study, 58 patients diagnosed with breast cancer and scheduled for neoadjuvant therapy will be recruited. Patient-derived organoids from their tumor biopsies will be utilized to evaluate the sensitivity of chemotherapy regimen. These drugs primarily include Doxorubicin, Carboplatin, Cyclophosphamide, Paclitaxel, as well as targeted therapies such as Herceptin and Pertuzumab.

Read the detailed description

58 early-stage breast cancer patients scheduled to undergo neoadjuvant therapy will be recruited. Baseline information including medical history, ultrasound, Breast-Specific Gamma Imaging (BSGI), and magnetic resonance imaging (MRI) records, will be collected both before and after two cycles of chemotherapy. Tumor tissue from these patients will be obtained via biopsies guided by ultrasound. Patient-derived organoids (PDOs) will be established and cultured from the collected tumor tissue. Subsequently, these PDOs will be subjected to treatment with drugs from standard chemotherapeutic regimens for breast cancer. The growth of the organoids will be assessed post-treatment, and dose-response curves will be generated. For evaluating the clinical outcomes of the patients, the Residual Cancer Burden (RCB) system will be used to evaluate tumor histological responses in patients. The consistency between treatment responses observed in the PDO models and the clinical outcomes of patients will be evaluated through correlation analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BiopsyProcedure or surgery

    Before initiating neoadjuvant therapy, patients diagnosed with breast cancer undergo a tumor biopsy. The tissue obtained from the biopsy is utilized to establish organoids and conduct drug testing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation between drug sensitivity test results in patient-derived organoid models and clinical outcomes.

    The drug sensitivity test results obtained from patient-derived organoid models will be compared with the clinical outcomes.

    Measured: 2023.12-2025.06

Secondary outcomes (1)
  1. Comparison between drug sensitivity of organoid models and clinical imaging (MRI, ultrasound, BSGI) in predicting the efficacy of neoadjuvant chemotherapy.

    The sensitivity and specificity would be checked between drug sensitivity of organoid models and clinical imaging (MRI, ultrasound, BSGI) in predicting the efficacy of neoadjuvant chemotherapy.

    Measured: 2023.12-2025.06

Questions about this trial

What is this clinical trial studying?

An observational study of Organoids and Breast Cancer, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 7 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact ZHIGANG CHEN (+8657189713716, chenzg@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Correlation between drug sensitivity test results in patient-derived organoid models and clinical outcomes. (time frame: 2023.12-2025.06). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2025.
