[Differential-diagnostic value of changes in nuclear ploidy of prostate epithelial cells during the carcinogenesis process].
Ploidometry of prostatic cell nuclei at different stages of carcinogenesis was made in 80 patients using 8 mcm histological sections stained by Felgen. Ploidy of 1332 nuclei of prostatic epithelial cells and 396 lymphocytes (tissue ploidy standard) was studied on computer image analyser "Imager-CG (computer program version Avtan-San). The study covered interphasic nuclei of the cells of the germinative zones of normal and hyperplastic structures, areas of intraepithelial neoplasia and adenocarcinoma with various disdifferentiation degree. Significant differences in ploidy and proliferative activity of prostatic cells at different carcinogenesis stages were revealed. Ploidometry data may help to take decision in differential histopathological diagnosis of benign and malignant tumors of the prostate.
