Brief Summary
Based on the breast cancer organ platform, this experiment establishes a drug sensitivity test method that is closer to the body tumor in breast cancer, provides a basis for the accurate treatment of breast cancer, and discusses the possible mechanism of breast cancer drug resistance.

Outcome Measures
Primary Outcomes (1)
Detection of cell viability
1\. The organ-like organ was assayed for cell viability using CellTiter Glo 3D reagent, and the curve was used to obtain a half-inhibitory concentration range. The dose was adjusted according to the half-inhibition concentration range to obtain an accurate half-inhibitory concentration.
8 weeks before neoadjuvant chemotherapy
Secondary Outcomes (2)
Detection of in vitro model drug sensitivity
8 weeks before neoadjuvant chemotherapy
Clinical efficacy assessment according to RECIST criteria
8 weeks before neoadjuvant chemotherapy
Study Arms (3)

Eligibility Criteria
With the prolongation of human life and lifestyle changes, the incidence and mortality of cancer has increased year by year. Since 2010, cancer has become the leading cause of death. Among women, the incidence of breast cancer is the highest, and it shows a growing trend, which seriously threatens women's health. Breast cancer has a high degree of tumor heterogeneity, which leads to a great difference in sensitivity to chemotherapy among affected individuals. The drug resistance after chemotherapy leads to poor prognosis. Therefore, screening for breast cancer tumor cells is sensitive to chemotherapy. Molecular level studies of drug resistance are necessary.
You may qualify if:
- Patients with breast cancer and the largest tumor diameter ≥ 3cm No previous chemotherapy regimen age 18-65 years old Can obtain the tumor tissue specimens required for culture Heart, liver, kidney and bone marrow hematopoietic function is good Know and sign the informed consent form
You may not qualify if:
- Pregnant or lactating women Also suffering from other cancer patients There are serious uncontrolled medical diseases or acute infections Those who are known to be allergic to this study drug or a variety of previous drugs The patient cannot understand the purpose of the study or disagree with the requirements of the study.
- Other investigators believe that patients who are not suitable for this study group
