“This is potentially the holy grail of cancer research, to find cancers that are currently hard to cure at an earlier stage when they are easier to cure,” says Dr. Eric Klein of Cleveland Clinic’s Taussig Cancer Institute. “We hope this test could save many lives.”

In an early study by a research team that included scientists from Stanford University, Klein’s group found the test was most accurate in diagnosing pancreatic, ovarian, liver, and gallbladder cancers — finding the disease in four out of five patients who used it.

Tests for lymphoma and myeloma were slightly less accurate, with 77 and 73 percent detection rates, respectively. Lung cancer and cancers of the head and neck trailed behind, with 59 and 56 percent detection rates.

Researchers did note, however, that further “clinical development” was needed. They’d also need more test subjects, as the sample sizes were on the small side for a study of this type. While it detected ovarian cancer with 90 percent success rate, for example, only 10 instances of this type of cancer were detected throughout the testing period.

Still, the research shows promise in a blood-based approach to future cancer screening.
