SANTOS ARRONTES, Daniel et al. Transrectal protatic biopsy guidelines for patients older than 50 years in relation to PSA elaborated by a mathematical decision tree. Arch. Esp. Urol. [online]. 2005, vol.58, n.5, pp.413-416. ISSN 0004-0614.

OBJECTIVES: To decide the action politics (to perform or not transrectal prostatic biopsy) for a PSA cut point of 4 and 10 ng/ml through the construction of a mathematical decision tree. METHODS: We calculate the usefulness of the biopsy through a subjective score, from 0 to 10, established after a survey of the 20 staff members of the health-care area, applying an global analysis with creation of total profile cards through an orthogonal design. RESULTS: The main usefulness of prostate cancer screening would be not to perform transrectal prostatic biopsies when PSA is lower than 4 ng/ml.

Keywords : Prostatic neoplasia; Decision tree; PSA.
