Genome Medicine in Cancer: What's in a Name?

This is an exciting time to be in cancer medicine. New technologies, such as next-generation sequencing (NGS), have increased our understanding of the molecular aberrations that define cancer. This, in turn, has led to the identification of cancer-specific molecular targets and potential drugs to confront these targets. As these new technologies move toward clinical application, a new vocabulary of "genome medicine" has been introduced to the field of oncology. Unfortunately, unclear or incorrect use of the new terminology has led to semantic misunderstandings that impair communication between the basic research and clinical practice arenas. These misunderstandings have led to assumptions regarding the clinical application of NGS and other technologies that may or may not be true. For example, some organizations that perform NGS testing on clinical samples have endorsed use of the results of such tests to direct specific therapies based on laboratory hypotheses, but without clinical testing of the hypotheses to show utility for these potential predictive claims. Here, we review some simple, and hopefully universally acceptable, definitions, concepts, and trial designs so that laboratory researchers and clinicians can move closer toward speaking the same language. ©2015 American Association for Cancer Research.
