Noninvasive sensor technologies for disease detection via breath Volatolomics

The use of a volatolomic signatures based on volatile organic compounds (VOCs) is a novel and tested approach for diagnosing different diseases. Sensors have a high potential as easy to use point-of-care systems. In this talk we will focus on recent achievements in Gastric cancer study. It was previously shown that GC can be diagnosed from breath. In previous study on GC we classified sensors on a training and validation population of 484 people. In recent work we further extent the latter and use the database of 441 people, (excluding 43 dysplasia and peptic-ulcer samples) as the training classifier for screening a new set of 726 presumed non-cancer volunteers.
