Breath biomarkers could aid early detection, helping to improve long term survival
Esophageal and stomach cancers are amongst the most commonly occurring cancers with 456,000 and 952,000 new cases respectively diagnosed globally in 2012 . Early stage
To understand the breath composition of esophageal-gastric cancer patients Sung Tong-Chin et al.  collected breath using the ReCIVA Breath Sampler. By taking advantage of the ReCIVA Breath Sampler’s ability to collect four technical replicates during a single breath collect, they were able to analyze breath using multiple mass spectrometry approaches, thus achieving detailed breath volatile organic compound (VOC) structural data. Figure 1 shows the relative intensity of VOCs, across a population of 21 patients with esophageal-gastric cancer. This provides a useful basis for designing and interpreting future studies aiming to find early stage breath disease biomarkers in the patient population.
