Genomic insights in gynecologic cancer.

Recent technological advances in DNA sequencing have enabled a remarkably detailed understanding of the molecular changes that define gynecologic and other cancers. Several groups have carried out large-scale genomic analyses of ovarian, uterine, and most recently, cervical cancer. These analyses have led to new insights into the molecular changes characterizing these cancers, which provide insight into clinical outcomes. These molecular characterizations have similarly led to new genomic-based classification schemas, which may better stratify clinical outcomes, help prognosticate and guide treatments. Discovery of characteristic mutations may also provide potential new targets for molecularly targeted chemotherapies, as has been already described with poly-ADP ribose polymerase inhibitors and ovarian cancer. The purpose of this article is to provide an overview of the defining molecular abnormalities and markers in gynecologic cancer, to discuss the clinical implications, and to provide a comprehensive view of the current state of genomic knowledge in gynecologic cancer.
