Abstract:This study aimed to comprehensively clarify the genomic landscape and its association with tumor mutational burden-high (TMB-H, ≥10 mut/Mb) and microsatellite instability-high (MSI-H) in endometrial, cervical, and ovarian cancers. We obtained genomic datasets of a comprehensive genomic profiling test, FoundationOne® CDx, with clinical information using the “Center for Cancer Genomics and Advanced Therapeutics” (C-CAT) database in Japan. Patients can undergo the tests only after standardized treatments under un… Show more
“…The most common mutations affect the PTEN gene, but mutations in other genes like PIK3CA, KRAS, and ARID1A are also frequently observed [ 47 ]. Of particular importance is the PI3K pathway, known to play an important role in genomic stability, cell cycle regulation and cell survival, resistance to chemotherapy, and DNA replication [ 48 ]. Inhibition of this pathway may lead to genomic instability and mitotic catastrophe [ 48 ].…”

Since the 2009 FIGO staging update, focused exclusively on the anatomic extent of disease, there have been several advances in the understanding of the pathologic and molecular features of endometrial cancer. In a significant departure from the 2009 FIGO staging system, the 2023 FIGO staging update integrates both histopathological and molecular classification. With the inclusion of non-anatomic pathologic parameters such as histology, tumor grade, lymphovascular space invasion, and molecular subtype, the 2023 FIGO staging update aims to create more clinically relevant substages that improve prognostic value and allows for more individualized treatment paradigms. This review will evaluate the clinical impact of the 2023 FIGO staging update, describe the stage shifts that lead to higher prognostic precision, and illustrate the current state of molecular analysis in clinical practice. Furthermore, this review will explore how incorporating factors such as molecular subtype into endometrial cancer staging can offer valuable insights into the racial disparities seen in morbidity and mortality.
