title: [Determination of cost-effective strategies in colorectal cancer screening].
abstract: The object of the article is to implement particular methodologies in order to determine which strategies are cost-effective in the mass screening of colorectal cancer after a positive Hemoccult test. The first approach to be presented consists in proposing a method which enables all the admissible diagnostic strategies to be determined. The second approach enables a minimal cost function to be estimated using an adaptation of "Data Envelopment Analysis". This method proves to be particularly successful in cost-efficiency analysis, when the performance indicators are numerous and hard to aggregate. The results show that there are two cost-effective strategies after a positive Hemoccult test: coloscopy and sigmoidoscopy; they put into question the relevance of double contrast barium enema in the diagnosis of colo-rectal lesions.
