COlorectal BReath Analysis (COBRA2)

Colorectal cancer (CRC) is the second most common cause of cancer death in the United Kingdom, with approximately 17,000 deaths per year. The five-year survival rate from CRC is only 10% when discovered at a late stage, but exceeds 90% if diagnosed early. Symptoms related to CRC can be non-specific, therefore the decision to refer for a colonoscopy can be challenging. There is a clear need to improve earlier detection of CRC so that patients with CRC can be identified earlier and faster, enabling them to start treatment more quickly. The study team is developing a non-invasive breath test that detects small molecules called volatile organic compounds (VOCs) that are specific to CRC. For patients with non-specific symptoms, this test would help GPs to identify those patients that may have underlying CRC, who would benefit from referral for specialised CRC tests.
