    Abstract:
    Feulgen-stained tissue sections of 187 invasive ductal carcinomas (94 with lymph node metastases; mean follow-up: 44 months) were studied using computer assisted image cytometry. Based on survival time, the prognostic significance of nuclear image analysis was compared with the results using conventional histopathological grading according to Bloom and Richardson, as well as with image cytometric DNA measurements. The histopathological grading has the disadvantage of poor interobserver reproducibility (71.1%). Despite statistically significant differences between the actuarial survival curves of grade 1 and grade 3 patients, the prognostic significance of the conventional grading method for individual patients seems to be low and the number of grade 2 cases (42.8%) is large. The quantitative morphological method for analyzing nuclear images gives more reproducible results. Compared to histopathological grading, the predictive values for good or poor prognosis are clearly higher and the number of cases with uncertain prognosis is significantly smaller (20.9%). DNA ploidy measurements also make it possible to distinguish statistically significant differences between favorable and unfavorable prognoses with respect to over-all survival time. However, the classification accuracy based on the best single parameter (DNA-histogram type according to Auer) is 70.2% compared with 78.9% for nuclear image analysis.
