New model establishes guidelines for earlier cancer detection
“The study’s results can be viewed as both bad and good news,” said Sanjiv “Sam” Gambhir, MD, PhD, professor and chair of radiology and the study’s senior author. (Sharon Hori, PhD, a postdoctoral scholar in Gambhir’s laboratory, is the lead author.)
The bad news, Gambhir said, is that by the time a tumor reaches a detectable size using today’s available blood tests, it is likely to have metastasized to other areas of the body, making it much more deadly than if it had been caught early on. “The good news is that we have, potentially, 10 or even 20 years to find the tumor before it reaches this size, if only we can improve our blood-based methods of detecting tumors,” he said. “We think our mathematical model will help guide attempts to do that.”
