New biomarkers can predict patients' response to certain drugs

Recent advances in cancer therapeutics have led to the discovery of biomarkers that can predict patient response to certain drugs. Screening for mutations in the epidermal growth factor receptor (EGRF) prior to non-small cell lung cancer treatment, for example, has been shown to indentify patients who are likely to respond to treatment with erlontinib. This maximizes the drug's impact, and spares patients who are not likely to benefit from being subjected to potentially debilitating side effects.
