Summary

High-risk endometrial cancer represents a heterogenous group of patients, including nonendometroid tumor types such as serous carcinoma, that are characterized by poorer overall survival, most likely due to higher rates of distant metastasis. For this reason, adjuvant chemotherapy can be considered in this particular population.Unfortunately, as these tumors represent an infrequent subset of patients, data are very limited.

A subgroup analysis of the NSGO9501/EORTC 55991 and MaNGO-ILIADE III trials did not show a survival benefit for patients with serous or clear-cell tumors. Data from retrospective analysis suggest that, in patients who did not undergo complete surgical staging, adjuvant therapy was associated with greater oncological outcomes.

In conclusion, adjuvant therapy should be considered in non-staged patients, when complete surgical staging is not feasible or within clinical trials. Future prospective clinical trials, including the constantly evolving molecular categorization, are needed to explore more effective treatment strategy for this unique patient population.
