Partial Wave Spectroscopic Detection of Colon Cancer Risk
The purpose of this study is to study samples of rectal mucosa (the moist lining of the
rectum) using a new light scattering technology, called partial wave spectroscopy (PWS)in
patients who will undergo a colonoscopy or a flexible sigmoidoscopy and have a history of
ulcerative colitis (UC). PWS has been recently developed to allow scientists to learn about
any changes to the cells that may indicate a risk of developing colon cancer. We believe
that the PWS test will more accurately detect the risk of colon cancer.
Observational Model: Cohort, Time Perspective: Prospective
Study samples of rectal mucosa (the moist lining of the rectum) using PWS.
Samples will be collected and then shipped to Northwestern University for analysis using PWS. This is to assess accuracy of detecting the risk for colon cancer.
