Patients Derived Organoids in Ovarian Cancer

Summary

Among cancer models, patients derived organoids (PDOs) best reproduce tumor's tissue architecture, intratumor heterogeneity and are able to mimic in vivo patients' drugs response. For these reasons, it has been designed a study to assess the feasibility of PDOs immune cells co-culture in OC patients and the concordance between ex vivo sensitivity and in vivo treatment response. If proven effective and reliable, PDOs could be introduced into clinical practice as empirical predictor of patients' response to antineoplastic drugs.
