Comparison of Barium Enema, Computed Tomographic Colonography, and Colonoscopy in Detecting Colon Cancer
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.
Other: screening questionnaire administration
Procedure: barium enema injection
Procedure: computed tomography
Procedure: computed tomography colonography
Procedure: diagnostic colonoscopy
Procedure: screening colonoscopy
|Study Design:||Primary Purpose: Diagnostic|
|Official Title:||Prospective Comparison of Air Contrast Barium Enema (ACBE), Computed Tomographic Colonography (Virtual Colonoscopy) and Colonoscopy for Evaluation of the Colon in Patients With Fecal Occult Blood|
|Study Start Date:||August 2000|
|Study Completion Date:||August 2005|
- 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.
Within 24 hours of completion of each test, patients fill out a questionnaire about their experience. At 5-7 days after completion of all tests, patients complete a final questionnaire comparing all 3 tests.
PROJECTED ACCRUAL: A total of 2,133 patients will be accrued for this study within 4 years.
