An international group of researchers has found that blood tests can be used to pick up on changes within lung cancer tumours. Detecting these changes can be useful in targeting lung cancer treatment.
Details of the study were presented at the European Lung Cancer Conference (ELCC) in Geneva, Switzerland last week (Friday 17 April).
Based on previous studies that suggest that DNA from tumours circulates in the bloodstream, the researchers aimed to find out whether blood tests could be a valid way to test for any changes, known as mutations.
The scientists compared the blood tests with the established tissue testing methods using samples from 1,162 people. They found that there was an 89% agreement rate between the results of the blood test and tissue testing.
The researchers have since been working to increase the sensitivity of their DNA blood tests and are conducting further research.
