Yale SPORE in Lung Cancer News

A new blood test can tell if cancer has returned months before a scan

Blood tests looking for cancer markers have been around for decades, but the latest generation of tests hunt for tiny fragments of an individual cancer’s DNA in a person’s blood. These tumor-informed tests are a striking advance in what’s known as circulating tumor DNA (ctDNA) analysis, and researchers at Yale are already seeing intriguing results. The goal is to personalize cancer treatment for individual patients. “The technology is exciting because we can monitor outcomes in real time and determine who needs more or less treatment,” says Roy Herbst, deputy director of the Yale Cancer Center.
