Chemosensitivity Assays for Ovarian Cancer

Point: Chemosensitivity Assays Have a Role in the Management of Recurrent Ovarian Cancer

In this era of personalized medicine, patients with recurrent ovarian cancer deserve better than the 25% response rate that is associated with drugs selected based on clinical information alone. In the past decade, marked laboratory improvements have enabled chemosensitivity assay testing to yield a 0.70 correlation with response, and to accurately predict progression-free and overall survival. Compelling retrospective data supporting the use of this technology cannot be ignored while waiting for a cooperative group to test whether chemosensitivity assay should be used to direct salvage therapy.

Counterpoint: Chemosensitivity Assays for Recurrent Ovarian Cancer

Unfortunately, no reliable evidence-based data have shown any in vitro chemosensitivity assay strategy to be clinically useful in the management of recurrent ovarian cancer, despite frequent use. Several clinical trials have been proposed with the potential to support or refute the relevance of these approaches.
