Nuclear-DNA-cytophotometry used for the automation of cytological diagnosis of malignancy has the following advantages compared to image analysis: 1) DNA-cytophotometry mostly yields more sensitive parameters for the diagnosis of malignancy than image analysis does and thus results in greater diagnostic accuracy. 2) Cytological diagnosis of malignancy may often be possible in earlier stages of the tumor-history with nuclear-DNA-parameters compared to morphological parameters. 3) The prognostic validity of nuclear-DNA-distribution is probably greater than of cytomorphological parameters. 4) The parameters of nuclear-DNA-distribution for cytodiagnosis and grading of malignancy are the same for most of the human tumors in contrast to morphological parameters which are different for histogenetically different tumor. 5) Processing time for the automated diagnostic procedure of the slides will be much shorter if the Feulgen-stain for DNA is used instead of the Papanicolaou-stain for image analysis. One disadvantage of nuclear DNA-measurements as a diagnostic toll is the fact that cytopathologists cannot fully control the diagnostic process and results with their own eyes in Feulgen-stained slides. Meanwhile, however, even in other medical disciplines diagnosis are made by objective measurements of parameters which are not discernible by the human eye. That diagnostic procedure has to be accepted which yields the most accurate and reproducible diagnosis in the shortest time. It is recommended to combine cytomorphological and DNA-cytophotometric parameters as diagnostic tools for automated cytodiagnosis in Feulgen-stained slides.</p>","PeriodicalId":76159,"journal":{"name":"Microscopica acta.

A series of 1176 Feulgen stained cervical smears has been analysed in an automated procedure using image transformation for cell selection and artefact rejection. During the analysis of the entire series new artefact rejection procedures have been added to the automated analysis.

The aim is to reach a better diagnostic level by eliminating human failure. All machine positives whether true positive or false positives have to be examined visually (by cytotechnologists or cytopathologists). If there are many false positives the system will be highly uneconomic. From a clinical point of view the number of false negatives is crucial. The false negative rate may in no case be higher than that reached by cytotechnologists and medical cytologists, but should, if possible be lower. Yardstick for the validation of prescreening systems can only be the diagnostic level of well kept cytologic laboratories of conventional cytology.
