Procedure for diagnosing lung cancer non-small by titration in human serum of epidermal growth factor receptor and its specific ligand, the epidermal growth factor.

摘要

Procedure for diagnosing NSCLC cancer by assessing in human serum of epidermal growth factor receptor and its specific ligand, the epidermal growth factor.; The invention consists of a new procedure that allows diagnosing cancer NSCLC. Consists in determining serum levels of human epidermal growth factor receptor in its soluble form (sEGFR) and its specific ligand, the epidermal growth factor (EGF). Once obtained concentration values ​​of both molecules in the serum of a given individual are compared with cutoffs, previously established, determining the probability of developing NSCLC.; This procedure to detect cancer NSCLC is based on a fast, simple, reliable and economical technique.
