title: [Clinical epidemiology using an electronic value-added tabulator. Application to cancer of the prostate in TNM classification and in calculating Kaplan-Meier curves].
abstract: The authors have been using the WHO-TNM 1977 classified, modified in 1982, for prostatic cancer for more than ten years. This classification has been considered to be insufficient to allow precise choice of therapeutic determinants and to accurately evaluate the results of treatments. A new WHO TNM 88 classification has been recently published and has raised many controversies in the urological literature which complicates the development of this classification. The authors have developed a value added system of TNM scoring using the Excel programme on a personal computer, which tries to integrate the various classifications 78-82-88. Very precise rules must be determined for information collection, the most reproducible medical indicators must be selected and they must be made as objective and as pertinent as possible. The rules of the WHO classification must then be formalized and introduced into the expert system as rules of production. The system allows optimal transcription of the scores from one classification to another, depending on the political orientations of the necessity of translation. Lastly, the system calculates, in real time, the actuarial survival and/or Kaplan-Meier curves for all of the events identified by an indicator for the patient files entered into the system.
