Urine test could catch lung cancer early

Graphical Abstract

Lung cancer could be identified earlier, thanks to a new test that uses surface enhanced Raman spectroscopy (SERS) to detect a cancer biomarker in urine

Detecting lung cancer is difficult as it is hidden in the body, and current clinical methods are not effective at an early stage; the one-year survival rate after diagnosis in the UK is just 29–33%. Acetyl amantadine (AcAm) is recognised as an exogeneous cancer biomarker because it is the product of a metabolic process known to be significantly up-regulated in cancerous cells. After ingestion, the antiparkinson and antiviral drug amantadine is acetylated in the body by the enzyme spermidine/spermine N1 acetyltransferase to give AcAm, which can be detected in patient urine. However, techniques previously used to quantify AcAm in urine, such as liquid chromatography-mass spectrometry (LC-MS), are undesirable for clinical adoption due to high costs and long run times.
