Genomics of uterine malignancies and the potential of precision medicine

Uterine malignancies represent a broad and heterogeneous group of neoplasms, which collectively account for the majority of gynaecological malignancies in developed countries. For a significant proportion of these, mortality rates and clinical outcomes are of major concern, owing to complex molecular profiles and aggressive phenotypes that are largely refractory to conventional therapeutic approaches. Recent advancements in precision medicine and the development of targeted therapies have been transformative for several common cancer types; however, the same benefits are yet to be realised for many uterine cancers. This review comprehensively details the diverse molecular features characterising the various subtypes of uterine malignancies. Furthermore, we have examined the therapeutic approaches actively investigated to target these unique molecular features, identifying pathways and treatments that offer the greatest potential patient benefit. Among increasingly personalised strategies, particular promise is shown by HER2-targeted therapies for HER2-positive malignancies (e.g. trastuzumab deruxtecan). Additionally, targeting TP53 wild-type tumours with selinexor, as well as addressing AKT and DNA repair pathways in both uterine carcinomas and sarcomas (i.e. AKT inhibitor and poly(ADP-ribose) polymerase inhibitor combinations), represents key advancements. Furthermore, anti-angiogenic and immune checkpoint inhibitor combinations hold significant promise for future therapeutic strategies.
