Because of the high mortality associated with advanced disease, accessibility to direct visual examination, extensive research, and recognition of the genetic mechanisms associated with its carcinogenesis, the colon and rectum have emerged as an important model for the introduction of innovative and effective cancer screening and early detection tools for large populations.
Detection of Colorectal Neoplasia: Need for Improved Methods
Wide-scale screening using fecal occult blood testing (FOBT) results in 15%33% reduction in colorectal adenocarcinoma mortality, but at the expense of many unneeded colonoscopies (16). Despite specificity of approximately 95% and reasonable cost-effectiveness, FOBT's test sensitivity ranges from 15% to 30% (7), leaving room for substantial improvement. Traditionally low FOBT sensitivities, reflecting standard office practice (8,9), may be improved when employed in an organized, structured program (10,11). The addition of sigmoidoscopy to FOBT increases the detection of adenomas by approximately
