[Morphometric characteristics (assessment of ploidy) of the degree of differentiation of uterine body adenocarcinoma].

53 histological slides obtained from 4 patients aged 35-68 years with diagnosis of uterine carcinoma without invasion (16 patients) and tumor invasion into uterine muscular membrane (24 patients) were retrospectively analyzed. On the basis of morphometry and ploidometry of 2989 nuclei on the image analyzer Imager-CG (Russia) with a computer program Avtan-San, a complex of diagnostic criteria characterizing the grade of malignancy of uterine tumors was obtained. Differential diagnostic ploidometric characteristics of 4 degrees of tumor progression are described. With the process intensification the amount of genetic material in tumor cell nuclei increase 1.7-fold, proliferative activity 2.2-fold, number of polyploid cells--1.5-fold. These data specify the degree of differentiation of uterine body adenocarcinoma and help to plan treatment policy for patients with uterine carcinoma.
