Oral cancer diagnosis using saliva

Researchers report an accurate, high-throughput, low-cost, and noninvasive method for diagnosing oral squamous cell carcinoma (OSCC) that uses a combination of conductive polymer spray ionization mass spectrometry and machine learning to detect changes in a wide range of OSCC-associated metabolites in saliva; the method was able to analyze saliva samples from 373 volunteers in 4.5 hours with a diagnostic accuracy of 86.7%, suggesting that the method might be used as a point-of-care-test for OSCC, according to the authors.
