Purpose of review
Clinically and on a molecular level, ovarian cancer is a unique and complex disease. The explosion in potential molecular targets over the last decade has led to the arrival of many novel therapies into oncology. In the present article, we review the most promising of these agents in ovarian cancer.
Recent findings
Targeted therapies, such as epidermal growth factor receptor inhibitors, that have worked well in other cancers have shown only moderate success in ovarian cancer, whereas other treatment approaches have yielded surprisingly positive outcomes. An example is anti-vascular endothelial growth factor and proapoptotic strategies, which are effective in both primary and relapsed ovarian cancer. Use of poly (ADP-ribose)polymerase inhibitors has shown that targeting one form of DNA repair profoundly affects cell survival in those with a hereditary failure to mend DNA damage using another mechanism. This can be extrapolated to patients with sporadic ovarian cancers, with or without the 'BRCAness' phenotype.
Summary
Using targeted agents in ovarian cancer, we are discovering not only how these novel therapies work but are also unveiling the complex 'wiring' of the disease itself, and the interconnections between what were previously believed to be distinct molecular pathways. The addition of targeted agents to our therapeutic armoury is likely to significantly and positively impact on patient survival.
