Abstract IA011: Leveraging ovarian cancer heterogeneity to drive precision therapeutic innovation

Abstract The past decade has brought unprecedented progress in understanding the genetics of epithelial ovarian cancer (EOC), but cures remain elusive due to the lack of insights into mechanisms that can be leveraged to develop new therapies. EOC is genetically heterogeneous and, therefore, it is imperative that therapeutic strategies become personalized by targeting distinct molecular subsets of EOC. Despite the importance of epigenetic regulators in EOC is increasingly recognized, the mechanism of action for these epigenetic regulators and the associated vulnerabilities exposed by their dysregulations have remained elusive for most of them. Here we will discuss our recent work on how to leverage epigenetic mechanisms and the associated rational combination strategies to address unmet clinical needs in genetically defined ovarian cancers through integrated approaches.
