Peripheral blood smears from the time of diagnosis of 64 patients with chronic myelogenous leukemia (CML) in chronic phase were restained according to Feulgen. Nuclear DNA content of at least 100 myeloblasts and promyelocytes was measured by interactive DNA-cytometry using a TV-image analysis system, combined with an automated microscope. From the resulting DNA values the DNA parameters stemline ploidy, stemline shoulder fraction and 'proliferative' fraction, which reflect cytogenetic and cellkinetik characteristics of CML, were derived. Each of these DNA parameters identified subgroups with a significantly different survival time and duration of chronic phase. Indicators for a good prognosis were a near-diploid stemline ploidy (median survival time 49 v. 26 months), a low percentage of nuclei in the stemline shoulder fraction (45 v. 28 months) and a high 'proliferative' fraction (45 v. 23 months). Independently of clinical and hematological features, the DNA-cytometric parameters yielded additional prognostic information both in the univariate and multivariate analysis.
