Clinical Context
CRC is the third most common cancer in men and women in the United States and is the second leading cause of deaths from cancer, as reported by Jemal and colleagues in the March-April 2008 issue of CA: A Cancer Journal for Clinicians. Tools for CRC screening include stool tests for occult blood or exfoliated DNA to detect cancer and structural examinations to detect adenocarcinoma and identify adenomatous polyps. Stool tests include the gFOBT, the FIT, and the sDNA. Structural examinations include FSIG, colonoscopy, DCBE, and CTC.
The American Cancer Society, the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology have collaborated on guidelines for the detection of adenomatous polyps and CRC in asymptomatic, average-risk adults 50 years or older.
