The scientific ambition of PRISM remains to develop therapeutic solutions based on novel technologies to meet the clinical needs. This will be achieved by promoting a strong interplay and transversality between the two pillars. Thus, in a continuous scientific trajectory each of the pillars will be organized around 2 similar WPs addressing respectively the investigation of the tissue microenvironment (WP1) and the development of therapies (WP2). The WP1of pillar 1 (COSMIX) will be thus dedicated to the development of new tools to investigate the microenvironment, its heterogeneity with single cell- and spatial proteomic-based approaches. These developments will be realized in the frame of the SIRIC pediatric project from INCA focused on pediatric glioma, the TRACK2SPACE project dedicated to tumors lacking actionable genomic alteration or the OMERIC project for single cell approach in BC, for examples. The WP2 of pillar 1 (NEXTGENESIS) will be dedicated to the development of therapies for the next generation surgery including the robotization of the SpiderMass to tackle the challenge of minimally invasive surgery and its combination to a novel direct phototherapy that will be developed and enabling cell apoptosis in the area recognized by the SpiderMass. It will also cover the development of non-invasive diagnostic tools for large-scale early diagnosis of BC and based on the detection of Volatile Organic Compounds (VOCs) by Mass Spectrometry and last generation sensors. Pillar 2, WP1 will be devoted to creating complex 3D models for drug and/or immunotherapy tests before preclinical essays on pet patients followed by clinical trials in human (BREASTMO), on one hand, and on the other hand, to investigating the role of nerve fiber in the tumor microenvironment and the involvement of tumor EVs in the crosstalk with the immune cells and in the brain metastatic niche in BC (NEUROCAN). Lastly, Pillar 2 WP2 (CARMA, PRODIGY) will be tackling the development of novel immunotherapy and strategies to improve their efficiency.
