Key Points Question Could esophageal cancer be detected by testing breathomics using high-pressure photon ionization time-of-flight mass spectrometry (HPPI-TOFMS)? Findings In this diagnostic study of 675 patients with and without cancer, esophageal cancer was accurately detected by testing breathomics with a sensitivity of 97.83% and specificity of 83.72% in the validation data set. Meaning These findings suggest that testing breathomics could help to improve the diagnosis of esophageal cancer.
