85 patients with prostate cancer and 20 patients with benign prostatic hypertrophy underwent DNA single-cell fluorescence photometry to investigate the possibility of DNA-related automatic diagnosis and grading of prostate cancer. The DNA histograms were analysed statistically by univariate data description, stepwise linear discriminant analysis and regression analysis. The accuracy for the malignancy diagnosis was 85.1 %, with 10.6% false-negative and 4.3% false-positive results. The accuracy of the malignancy grading, however, was very poor with only 39.5%.
