Simple blood test can detect lung cancer with high sensitivity and specificity - results from large clinical validation study published in the Journal of Clinical Oncology
Date:1/13/2014

o a billion people worldwide this century. In the U.S., it is the second most common cancer, but according to the American Cancer Society, lung cancer is by far the leading cause of cancer-associated death. More people in the U.S. die of lung cancer than colon, breast, and prostate cancers combined. The symptoms of lung cancer typically do not appear until the disease is already in an advanced, non-curable stage. Even when the symptoms of lung cancer do appear, they are often mistaken for other problems such as an infection or the long-term effects from smoking, which often delays diagnosis. As a result, over 80% of lung cancer patients die within two years of diagnosis.

About miRNAs and the MSC Lung Cancer AssayMicroRNAs (miRNAs) are small noncoding ribonucleic acids (RNAs) that modulate gene activity and are aberrantly expressed in cancer. They are tissue- and disease-specific molecules actively released by tumor cells and their microenvironment into the circulation packaged in exosomes or associated with ribonucleoprotein complexes to protect them from degradation. Due to their small size and stability, miRNAs can be measured in biological fluids such as plasma and serum and can serve as circulating biomarkers. Drs. Sozzi and Pastorino had reported the development and validation of plasma-based miRNA signatures from subjects in two independent LDCT screening studies, demonstrating that quantitative measurement by real-time RT-PCR of 24 circulating miRNAs is diagnostic and prognostic in lung cancer (Boeri et al., 2011). This biomarker assay is designed to offer the potential for early detection of lung cancer thereby avoiding the costs and complications associated with unnecessary tests following a false positive diagnosis using LDCT or chest X-rays.
