By way of gas chromatography-mass spectrometry (GC-MS), 509 gas samples were fully collected, and the resultant volatile organic compounds (VOCs) were used to train and test a Multilayer Perceptron Network (MPN) for differentiation. With differing volatile organic compound (VOC) compositions, intraluminal and exhaled gases achieved an AUC exceeding 0.95 in distinguishing UGIC (ESCC and GC) and early UG
