What this trial is about

Pancreatic adenocarcinoma (PA) is a solid cancer with a very poor prognosis with overall survival, all stages combined, not exceeding 5% at 5 years. The incidence and number of deaths caused by this type of tumor have been steadily increasing for two decades. In the absence of therapeutic advances, PA will be one of the leading causes of cancer deaths in 2030. In recent years, researchers and clinicians have now attempted to characterize and understand PA as a whole, through the various stages of its carcinogenesis and the analysis of its microenvironment. Indeed, the stroma of PA can represent up to 80% of the tumor mass and mainly composed of activated fibroblasts (CAF), endothelial and immune cells and extracellular matrix (collagen and fibronectin). However, the characterization of cell subtypes of this stroma is under study, as the pro or anti-tumor role of each cell subtype is not yet well understood. New technologies such as the CyTOF that has just been acquired by the ICM and the IRCM will make it possible to study these problems and to examine the cellular subpopulations that make up the tumor. On the other hand, active research is conducted to disrupt the dialogue between the tumor cells and those of the microenvironment. The search for innovative treatments in pancreatic adenocarcinoma requires the use of models of relevant preclinical studies. The most widely used models are based on cell lines of human origin used in vitro or in vivo after xenograft in immunodeficient mice. In particular, studies with pancreatic adenocarcinomas (PDX) derived tumors of patients reported that the response rate of PDX to certain drugs (gemcitabine, erlotinib ...) used clinically was similar to the response rates of patients enrolled in clinical studies. of these agents as monotherapy. A number of studies have evaluated the efficacy of targeted anti-tumor, anti-angiogenic or anti-stroma therapies from these PDTX models. Personalized medicine strategies can be envisioned as well as the study of new biomarkers, drugs or molecular mechanisms involved in therapeutic resistance. For several years, the investigators have been developing AP PTDX in the INSERM 1194 unit. The investigators propose to continue the development of this collection of pancreatic adenocarcinoma PDTX prospectively and to carry out their histological, molecular and mutational characterization.
