New Blood Test for Early Detection of Lung Cancer

Blood TestA recent revolutionary discovery by scientists has revealed a new way for early detection of lung cancer. This is a four-protein biomarker blood test that improves the risk assessment of lung cancer. This new blood test is a step forward for finding out which of the patients are likely to develop this deadly disease.

Scientists from World Health Organisation’s International Agency for Research on Cancer (IARC) in France have developed the test. According to the team, the test is capable of detecting 63% of future lung cancer patients among smokers or former smokers. The findings of IARC were published in the journal JAMA Oncology. Co-senior author, Sam Hanash, M.D., Ph.D., professor of Clinical Cancer Prevention at The University of Texas MD Anderson Cancer Center said, “This simple blood test demonstrates the potential of biomarker-based risk assessment to improve eligibility criteria for lung cancer screening with low-dose computed tomography.”

Blood Test Helps to Detect Lung Cancer at an Early Stage

The blood test works by looking for four specific protein biomarkers and determines the chances of developing lung cancer. The team has taken blood samples from 108 ever-smokers who went on to be diagnosed with lung cancer within a year of sampling. The four proteins found in the blood are precursor form of surfactant protein B (Pro-SFTPB), cancer antigen 125 (CA125), Cytokeratin-19 fragment (CYFRA 21-1) and Carcinoembryonic antigen (CEA). Australia is on number one for cancer deaths among men and women. The validation study was conducted among patients from European Prospective Investigation into Cancer and Nutrition and the Northern Sweden Health and Disease Study.
