    Abstract:
    A new method for the quality control of cytologic and histologic diagnoses of cervical lesions is based on the automated high-resolution scanning, image processing and computer analysis of cytometric data by the TICAS system. It determines and then compares optical-density-based ploidy patterns of cells in cytologic smears and the corresponding histologic sections, with the results available both as computer-graphic displays and printouts. Examples of the former appear for an "agreement case," in which the cytologic and histologic patterns corresponded, and a noncorrespondence (nonrepresentative) case, in which the tissue sample had been nonrepresentative of the lesion sampled by cytology. Computergraphic examples concern one case of condyloma and one of tissue repair, in both of which both the cytologic and histologic diagnoses had been overcalled. A further example shows the method's use in monitoring response to therapy. The DNA ploidy patterns on which this method is based can give diagnostic and prognostic clues when morphology alone may be equivocal or insufficient. The utility of ploidy pattern determinations of material from other body sites is also well established. With the use of microprocessors, the system described could be made inexpensive and operationally simple for the routine quality control of many cytopathologic studies as well as for the clinical follow-up of patients.
