Washington, DC — It’s the ultimate goal in the treatment of cancer: tailoring a person’s therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers at Georgetown Lombardi Comprehensive Cancer Center report a significant advance in this field of research using a new chip that looks for hundreds of mutations in dozen of genes.

The goal of personalized medicine is to determine the best treatment and the optimal dose carrying the fewest side-effect, especially as new drugs are discovered and treatment options increase. Variations in our genes encode proteins, which impact how a drug is metabolized or taken in by the cells. This directly impacts the drug’s effectiveness and the kinds of side-effects that may be caused by its toxicity.
