[Evaluation of cytomorphological parameters during hormonal therapy of prostatic carcinoma (author's transl)]

In 136 patients with prostatic carcinoma 544 aspiration biopsies were performed to study cytological signs of tumor regression caused by oestrogen therapy. For better interpretation a statistical evaluation of well defined regression signs in a constant number of cancer cells dependent on the tumor grading first was used. Additionally all data can be transferred to time diagrams. An approximate prediction of the future regression in cancer cells is possible.
