Scientists Closer to Blood Test for Early Lung Cancer Detection

by: cancercompass

Scientists have taken an important step forward in developing a blood test for the early detection of lung cancer.

According to a recent press release from the Fred Hutchinson Cancer Research Center in Seattle, a team of researchers has identified an immune system response to specific proteins produced by early-stage, cancerous lung tumors.

Using blood samples from 85 smokers diagnosed with lung cancer and 85 smokers without lung cancer, researchers tested for the presence of autoantibodies produced by the immune system to combat three proteins linked to early stage cancer.

The test concluded that the autoantibodies were present in more than half of the smokers who had developed cancer.

According to Dr. Samir Hanash, of the Fred Hutchinson Cancer Research Center, the findings are "an important step toward developing a biomarker-based blood test for the early detection of lung cancer."

Hanash and his team hope to develop a simple blood test that can be partnered with imaging techniques to improve lung cancer detection in its early stages.

The research has been added to the Journal of Clinical Oncology.
