简要总结
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for cancer. New diagnostic procedures such as computed tomographic colonography may provide a less invasive method of identifying patients who have colon cancer.
PURPOSE: Diagnostic and screening trial to compare the effectiveness of barium enema, computed tomographic colonography, and colonoscopy in detecting of colon cancer.
详细描述
OBJECTIVES:
- Compare the accuracy of air contrast barium enema, computed tomographic colonography (virtual colonoscopy), and colonoscopy for the detection of colonic lesions in patients with factors related to colon cancer.
- Compare the patient experience during each of these imaging tests.
OUTLINE: This is a multicenter study.
A repeat fecal occult blood test is performed. Patients then undergo an air contrast barium enema (ACBE). At 7-10 days after ACBE, patients undergo a computed tomographic colonography (virtual colonoscopy) followed by a colonoscopy on the same day.
A repeat ACBE may be performed if there is a discrepancy between the initial ACBE and colonoscopy. If the repeat ACBE continues to show an abnormality, patients undergo a second colonoscopy.
