Basal cell-specific anti-cytokeratin antibody (34 beta 12) decorates the basal cells of benign prostatic epithelium by standard immunohistochemical techniques, whereas adenocarcinoma of the prostate lacks immunoreactivity with this antibody. We reviewed our experience with this antibody to determine its utility in the diagnosis of adenocarcinoma of the prostate as well as its pattern of usage at a tertiary medical center. In all, 7,242 prostate specimens from 5,262 men were seen at Johns Hopkins Hospital between 1/89 and 4/93. Immunostaining for basal cell-specific cytokeratin (34 beta 12) was originally used for diagnostic purposes in 289 questionable areas from 228 cases; 45% of these cases were seen in consultation. The distribution of cases using 34 beta E12 was 52% needle biopsies, 32% transurethral prostatic resections (TURPs), 13% radical prostatectomies, and 3% open enucleations. These procedures constituted 2.8% of all needle biopsies, 7.2% of all TURPs, 1.7% of all radical prostatectomies, and 3.5% of all enucleations seen during this time period. For this study the hematoxylin and eosin stain was reviewed without knowledge of the original diagnosis, a diagnosis was favored, the 34 beta E12 stain was examined, and a final diagnosis was determined. The 34 beta E12 stain established (14%), confirmed (58%), or changed (2%) our favored diagnoses, while 18% remained or became equivocal. The 34 beta E12 stain was of no use in 8% of the cases, yet we felt we were still able to render a final diagnosis even without the help of the stain. The differential diagnoses in the questionable foci using 34 beta E12 were cancer versus focus of atypical glands (44%), adenosis (39%), prostatic intraepithelial neoplasia (PIN) (8%), basal cell hyperplasia (5%), and atrophy (4%). However, 34 beta E12 was used in only 15-20% of all cases of adenosis and basal cell hyperplasia and in
