[Comparative cytologic and flow-through cytophotometric studies in prostate cells (author's transl)].

Concerning the content of DNA, there are significant differences between nuclei of cells from the adenoma and those from the carcinoma of the prostate. As it is possible to measure these differences by using flow-through cytophotometry, this method might also be capable of automatizing the cytology of this organ. In a clinical study, the results of cytologic examinations and flow-through cytophotometric tests of the prostate are compared. They are comparable in the case of benign diseases of the prostate. In carcinomas of the prostate, cytology gives more positive results than flow-through cytophotometry. An improvement of these findings seems possible through the technical amendment of the method. The number of probes that can not be interpreted are fewer with flow-through cytophotometry than with cytology.
