<jats:title>Abstract</jats:title><jats:p>Proposed in this article is a new system for the cytological grading of therapy‐induced regression of prostatic carcinoma. Reversible and irreversible criteria in cytoplasm, nuclei, and nucleoli are distinguished and rated independently of each other on a scale of 0 to 2; the cellular regression grades r1‐r3 are the sum of rating numbers. Criteria that are invalid for grading regression are pointed out. Results of the clincial testing of this grading system are presented. Diagn Cytopathol 1987;3:108‐111.</jats:p>
