Early Detection of Cancer Onset Based on Sensing Field Cancerization at the Organ Level in the Alimentary Tract Using an Integrated Stimulated Raman/Scattering Modality for Endoscopic Real-time in Vivo Measurements

The investigators hypothesize that detection of field cancerization in the GI tract could be performed during endoscopy by performing Raman and scattering measurements. Together with the Technical University of Munich (TUM) and the Universidad Carlos III de Madrid (UC3M), the investigators have developed an investigational medical device that integrates probe-based Raman and scattering measurements for endoscopic purposes: the SENSITIVE system. During preclinical ex vivo studies, the investigators have established that measurements of the SENSITIVE system were able to discriminate between non-field cancerized tissue and field cancerized tissue. Considering these results, the investigators aim to assess the safety of in vivo Raman/scattering during endoscopy. Secondly, the investigators to assess the feasibility of this approach measurements to determine field cancerization in the alimentary tract during endoscopy through the SENSITIVE system.
