Prospective Multicenter Study Evaluating Feasibility and Efficacy of Tumor Organoid-based Precision Medicine in Patients With Advanced Refractory Cancers

We need a biopsy for PDO: PDOs are tridimensional multicellular structures expanded in vitro which retain the genotypic and phenotypic features of their tissue or tumor of origin. PDOs can be exposed to a panel of drugs (chemotherapy, hormonal therapy, targeted therapy) in order to study their sensitivity to each agent (or combination of agents) tested ('chemogram'). Recent studies showed that PDOs can accurately predict the response to treatment of solid tumors and could therefore inform clinical decision on the best therapeutic option for each patient.
