Exhaled Breath Biomarkers in VOCs for Early Detection of Cancer

Biomarker studies using exhaled breath are rapidly emerging as a novel approach for early disease detection and precision medicine. In my last blog article on Breath Biopsy, I introduced the concept of using exhaled breath samples to identify changes linked with health and disease. As an alternative to painful biopsy procedures, this novel breath analysis workflow offers a non-invasive experience for patients. Breath biopsy has the potential to improve patient wellbeing while simplifying clinical workflows. Using this approach provides an entirely new way to access metabolic information, by collecting and analyzing breath samples for early disease detection, detecting and monitoring response to treatments, or measuring exposure to hazardous substances and their impact on the body.

Billy Boyle, the Co-Founder and CEO of Owlstone Medical, told this interview how he is planning to use Breath Biopsy and the Orbitrap GC-MS to save 100,000 lives and $1.5 billion in health care costs.

Liquid biopsy vs. Breath Biopsy

While blood, urine, and stool tests have become commonplace ways to identify illnesses, the development of breath tests has lagged, and the primary reason is there was no reliable way to collect a breath sample and to analyze it. With Breath Biopsy, Owlstone Medical is leaping those hurdles with its standardized breath collection and its VOC analysis technologies.

Unlike liquid and tissue biopsy, which require blood or tissue samples to be taken, exhaled breath sampling is completely non-invasive. Breath analysis, however, requires a highly sensitive analytical technique capable of accurately measuring the broad range of exhaled volatile organic compounds. Today, we will learn how low- and high-abundance biomarkers can be quantified from exhaled breath using high‑resolution accurate mass (HRAM) mass spectrometry (MS) as the Orbitrap GC-MS.

Quantitative Biomarker Discovery with GC-MS

Historically, the robust and reproducible analysis of VOCs in breath has posed many technical and analytical challenges, which have led to limited agreement between different studies. Today, there are different tools available that can be used for quantitative analysis of exhaled breath. Out of the available techniques, the most effective analytical method is the Gas Chromatography-Mass Spectrometry (GC-MS) coupled to a thermal desorption (TD) unit. This provides highly specific information on the qualitative and quantitative presence of VOCs in exhaled breath, making it the gold standard for the untargeted analysis required in biomarker discovery. Excellent long-term stability makes GC-MS capable of reproducibly measuring potential VOC biomarkers at the low concentrations present in exhaled breath. Within the clinical environment, there is a need to collect both quantitative and qualitative information from a single run. Likewise, it is necessary to discover both extremely high and extremely low concentrations of compounds in a sample. The Orbitrap GC-MS in this particular case takes advantage of its high-resolution capabilities, the wide dynamic range and mass accuracy that provides fast and confident identification.

At this relatively early stage in the development of the Breath Biopsy field, the ability to identify and investigate the role of specific biomarkers is a key advantage in developing effective breath tests for clinical applications. A full-scan high-resolution data provided by an Orbitrap GC-MS offers the capability and flexibility to leverage sampled data at a later stage for re-evaluation. This provides scientists and researchers a simplified way for a retrospective deep dive into results, but also to increase the amount of relevant sample data, to target specific compounds, and perform required quantification potential biomarkers. And that is essential to build up an understanding of what is normal, abnormal, or critical when variations in the sample are monitored.

A key benefit of the quantitative approach is that, once biomarkers have been identified and thoroughly validated, a wider range of options are available for their subsequent development. Well-characterized biomarkers can be investigated within differing patient populations, irrespective of whether the same technology is used for analysis. It is this level of versatility that makes quantitative discovery methods extremely advantageous when creating a clinical test which could be approved by regulatory bodies. Breath Biopsy is now in use at over 100 clinical sites worldwide investigating various diseases that are listed in the image below.

Breath Biopsy represents a non-invasive, adaptable and accessible means to detect and measure biomarkers – which are closely linked to disease activity. The clinical applications for breath biomarkers are wide-ranging, with numerous applications in both precision medicine and early detection.

Transforming Disease Detection and Precision Medicine with Breath Biopsy

Breath Biopsy is a revolutionary technology that has the potential to fundamentally alter our approach to disease detection and precision medicine. This noninvasive method of analyzing exhaled breath for biomarkers has the potential to revolutionize patient comfort and improve clinical workflows. Utilizing Gas Chromatography-Mass Spectrometry (GC-MS) coupled with a thermal desorption (TD) setup provides highly specific information on the qualitative and quantitative presence of volatile organic compounds (VOCs) in exhaled breath, making it a useful tool for biomarker discovery. As Breath Biopsy continues to be adopted globally, one can anticipate that it will play a significant role in the early detection of numerous diseases. This innovative tool brings us closer to achieving our objective of improving patient health while potentially saving countless lives and reducing healthcare costs.
