Establishment of an ex Vivo Tumor Collection of Triple-negative Breast Cancers in Order to Validate the Interest of Innovative Therapies and the Search for Predictive Biomarkers of Response to Treatment

Initially described in 2009 on LGR5 positive stem cells from intestine, organoids correspond to a 3D cell culture that preserves the organization and part of the initial function of the organ from which the cells were derived. They use the proliferation and differentiation properties of stem cells cultured in a three-dimensional matrix. These principles have been adapted to many human organs, including the breast. These culture conditions have thus allowed the establishment of cancer organoid lines that have the advantages of rapid amplification, a high rate of establishment success and unlimited proliferation potential. They are transfectable and cryopreservable. They are very close morphologically and genetically to the tumor from which they derive. Very recently, the in vivo response of orthotopic xenograft models of breast cancer organoids has been correlated to the in vitro response of these same organoids. In addition, the in vitro response of various of these models to PARP inhibitors was linked to the presence of the BRCA1/2 mutant signature, highlighting the potential of these models to predict patient response to these treatments. Furthermore, one study demonstrated the value of using organoids derived from metastatic gastrointestinal tumors to predict patient response to cancer treatments (100% sensitivity, 93% specificity, 88% positive predictive value, and 100% negative predictive value.

Drug Response Testing and Repurposing Using Glioblastoma Organoid

The aim of this observational study, based on a prospectively collected cohort, is to evaluate the prognostic value of patient-derived organoids in predicting responses to conventional and repurposing drugs, including temozolomide, in patients with primary or recurrent glioblastoma. The primary question is whether the patient's response to temozolomide is recapitulated in their corresponding patient-derived glioblastoma organoid (GBO). Patient drug responses are evaluated using survival data, while GBO drug responses are assessed through a drug-response testing platform utilizing cell viability assays. Additionally, this platform is used to explore the potential application of various chemotherapeutic agents.

Observation of Clinical Consistency of Organoid-chips Drug Sensitivity in Chemotherapy for PCa With Visceral Metastasis

This project plans to establish an organoid chip model of prostate cancer patients with internal organ metastasis from surgical or biopsy tissue sources, and test the sensitivity of commonly used chemotherapy drugs based on organoid chip drug sensitivity testing technology to screen out sensitive individualized treatment plans.

Patient-derived Organoids of Lung Cancer to Test Drug Response

This is a single center, single arm, open and exploratory clinical study, with 50 cases planned for a period of 3 years. The purpose of this study is to evaluate the consistency and accuracy of a Patient-Derived Organoid (PDO) Model of lung cancer to predict the clinical efficacy of anti-cancer drugs, in order to predict the best chemotherapy regimen for each given patient.

Organoids Predict Therapeutic Response in Patients With Multi-line Drug-resistant Lung Cancer

This is a single-center, single-arm, open and exploratory clinical study. The purpose of this study was to evaluate the consistency and accuracy of the organogenic (PDO) model for patients with lung cancer, to predict the clinical efficacy of anticancer drugs, and to speculate and select personalized treatment regiments for patients with lung cancer who are resistant to multi-line standard therapies.
