The challenge in pharmacogenetics is not only finding good markers, but also if and when to use them. In the case of colon cancer management, there are well-established genomic, proteomic and pharmacogenetic markers predicting efficacy of medical therapy and informing prognosis. The question before physicians and health care organizations is whether this testing has sufficient clinical utility-which is to say what individuals are appropriate to test, whether the testing is cost-effective, and if there is ultimately improved clinical outcome.
