Diagnosing brain tumours with a blood test

A blood test to diagnose and classify tumours could be revolutionary and practice-changing for patients and clinicians alike. In many cases, a simple blood sample could take the place of more invasive surgery to obtain tissue samples – resulting in better treatment planning and less anxiety for patients.

In an OICR-supported study recently published in Nature Medicine, researchers have shown that a simple but sensitive blood test can accurately diagnose and classify different types of brain tumours. With further research and development, the test could serve as a less-invasive method to detect, diagnose and classify the severity of brain tumours.

The study was also presented virtually on June 22 at the Opening Plenary Session of the American Association for Cancer Research Annual Meeting 2020: Turning Science into Lifesaving Care.
