title = "Improving colorectal cancer detection by extending the near-infrared wavelength range and tissue probed depth of diffuse reflectance spectroscopy: A support vector machine approach",
abstract = "Colorectal cancer (CRC) is the second most deadly and third most common type of cancer worldwide. In this study, we assessed the improvement of the diagnostic potential of diffuse reflectance spectroscopy (DRS) for CRC detection upon extending the tissue probed depth (up to 2mm) and wavelength ranges (350-1919 nm) investigated in previous studies. We analyzed almost 3000 DR spectra (7.5 times more than previous studies) collected with 630-?m and 2500-?m source-detector distance probes by using support vector machines with potential to automate tissue classification. We achieved 96.1\% sensitivity and 95.7\% specificity and 0.987±0.005 AUC on tissue classification.",
