The association of clinical, pathogenesis and mutational profile of patients affected by ovarian cancer have improved the armamentarium of therapies available for medical doctors. One of most remarkable advancements is represented by the introduction of PARP inhibitors in the front-line setting of advanced ovarian carcinoma. It is necessary to continue with this effort and introduce novel approaches to improve the survival rate as well as predictive biomarkers to approved therapies. Given the absence of predictive biomarkers to standard therapy, patients derived organoid could be a promising platform to test clinically available drugs and/or promising new molecules to explore the tumor sensibility in an ex-vivo model. The aim of this study is to correlate treatment sensibility measured in tumor derived organoids to clinical sensibility seen in real world patients.
