Abstract Background  Margin status is an important prognostic factor for treating colorectal cancer. This study aimed to investigate the usefulness of a multimodal spectroscopic tissue scanner for real-time cancer diagnosis without tissue staining. Patients and methods  Diffuse reflectance spectra (DRS) and fluorescence spectra (FS) of
