Could a new one-and-done blood test designed to detect as many as 50 different types of cancer become a diagnostic game changer?
Yes, say researchers, who report the method appears accurate and reliable at identifying and locating cancer, including some kinds for which there are now no effective screening methods.
“[The test] sets the stage for a new paradigm of screening individuals for multiple cancer with a single blood test, as opposed to the current situation where we screen for individual cancers,” said study leader Dr. Eric Klein, chairman of the Glickman Urological and Kidney Institute at the Cleveland Clinic.
The new blood test looks for the presence of so-called cell-free DNA (cfDNA), a telltale sign of cancerous tumors.
The latest round of testing involved roughly 2,800 participants already diagnosed with cancer and 1,250 who were healthy. The results were dramatic, Klein said.
