Despite therapeutic advances, patients with advanced or recurrent disease still have a poor prognosis, with high recurrence rates and a 5-year survival of less than 20%.\n\nRecently, four phase III studies (RUBY, NRG-GY018, AtTEnd, and DUO-E) have demonstrated that the addition of anti-PD-1\u002FPD-L1 immunotherapy to first-line chemotherapy significantly improves progression-free survival, particularly in tumors with altered DNA repair mechanisms known as mismatch repair (MMR) (so-called mismatch repair-deficient or dMMR tumors), but with benefits also observed in a subset of tumors with normal MMR function (so-called MMR-proficient or pMMR tumors). However, despite the clinical approval of these therapies, reliable biomarkers capable of predicting response to immunotherapy are still lacking.\n\nThis project aims to comprehensively characterize the genomic, epigenetic, and lipid properties of the tumor and the tumor microenvironment (TME) in order to identify predictive markers of response to immunotherapy, thereby laying the foundation for a personalized therapeutic approach in endometrial carcinoma.",[65,66,67],"Endometrial Carcinoma (EC)","pMMR","DMMR Cancer","NOT_YET_RECRUITING","2026-01-21",{"date":71,"type":72},"2026-01-29","ACTUAL",{"date":69,"type":59},{"date":75,"type":59},"2027-11-30",{"name":5,"class":6},1]
