Speaking with BioQuick News, Kristein King, Vice President, Certis Oncology Marketing, said that Certis Oncology is leading thefunctional precision oncology category within personalized medicine. The following material is a summary of Ms. King’s comments to BioQuick News. Unlike genetic/tumor profiling, functional testing involves directly exposing a patient’s cancer cells to a variety of potential treatment options to evaluate relative efficacy and guide clinical decision-making. A variety of test systems can be used in functional testing, including 2- and 3-dimensional cells cultured in vitro (i.e., organoids), fruit flies, zebrafish, and mice—the animal model most commonly used in cancer research.
