Detection of Colorectal Cancer in Patients With a Positive Fecal Immunochemical Test Using an Electronic Nose Device (AeoNoseTM)

The present study aims to investigate the diagnostic accuracy of exhaled breath analysis with the Aeonose (the eNose Company, Zutphen, the Netherlands) to distinguish the breath of patients suspected for CRC (based on a positive fecal immunochemical test), who are truly diagnosed with CRC, from patients suspected for CRC in whom this diagnosis is rejected after colonoscopy.
