Colorectal Cancer Screening Validation Study

Conditions
Colorectal Cancer Screening
Registration Number
NCT00720993
Lead Sponsor
IntelliGeneScan, Inc.
Brief Summary

The purpose of this study is to evaluate the gene expression patterns from colorectal mucosal cells collected through the use of a standard anoscope and cytology brush. Patients will include those scheduled for routine colonoscopy procedures and those with confirmed colorectal cancer.
