Two cell surface receptors might be responsible for the most common form of lung cancer spreading to other parts of the body, according to a study led by the Translational Genomics Research Institute (TGen).

The hepatocyte growth factor receptor (HGFR/MET) and fibroblast growth factor-inducible 14 (FN14) are proteins associated with the potential spread of non-small cell lung cancer (NSCLC), according to the TGen study published online April 8 by the scientific journalĀ Clinical & Experimental Metastasis.

NSCLC represents more than 85 percent of all lung cancers, which this year will kill an estimated 159,000 Americans, making it by far the leading cause of cancer-related death. It has a 5-year survival rate less than 10 percent.
