title: Grade and histochemical R-1881 binding in prostatic cancer.
abstract: Comparison of the grades classified by Gleason with R-1881 binding which was attributable to total androphilic proteins in tissues was performed in 42 untreated and 13 relapsed prostatic cancers. Increasing malignancy correlated with loss of staining on R-1881 binding when examined both in primary pattern and in individual tumor cell clusters. In relapsed cancer, however, there was no R-1881 binding irrespective of any grades.
