Background Information With the advance in cancer biology, we realize that malignant neoplasm is related with different biological patterns in metabolome and microbiota. Because of the progress in optical spectrometry, it has become possible to evaluate whole visible and innon-visiable absorptive spectrum in human specimens, which may enable detection of minor changes in compound related with altered metabolome and microbiota. We hope to utilize hyperspectral imagingthis spectrum technology to reveal the possible clues of neoplasm for early stage detection

Material and Methods This research intended to enroll one hundred patients into the study. This includes patients with positive stool or urine analysis admitted for workup of colorectal cancer. We will scan the stool and urine with hyperspectral imaging sensoroptical spectrometer, which utilize multichannel charge-coupled device and InGaAs array to analyze the full spectrum of light patterns. The image pattern will be stored and used to linked final diagnosis. Absorption, scattering, and reflection spectra are expected for analysis. Follow up analysis after cancer staging will be used for lowering background noise in all spectra.

Expected Results We expect that there will be specific spectral pattern in stool of colorectal cancer patients, which may be related with cancer staging and different from those in patients without malignancy. Difference in spectra will lead to discovery of new biomarker for colorectal cancer and related diseases. The optic spectra pattern of stool and urine may assist early diagnosis and staging of different malignancies
