Key Points Question Can the development of a diffuse reflectance spectroscopy (DRS) probe aid cancer margin assessment in esophageal and gastric cancer surgery? Findings In this validation study including 37 patients, the development of a DRS probe and tracking system showed that machine learning can provide real-time discrimination of normal and cancer tissue with high diagnostic accuracy of 93.9% and 96.2% for gastric and esophageal specimens, respectively. Meaning This study highlights the potential for the DRS system to be used intraoperatively to aid cancer margin assessment in real time.
