Abstract:
PSA and PSAP were examined in 198 prostatic biopsies and correlated with PSA and PSAP serum levels evaluated before biopsies. In every type of lesion there was no relation between PSA or PSAP serum levels and their expression in biopsy specimens. PSA and PSAP staining was similar in both cancer and benign hyperplasia and lower in dysplasia, atrophy and prostatitis; while serum levels were higher in adenocarcinomas than in other lesions. A significant difference of PSAP serum levels was noted in different Gleason's grading of neoplasia, found neither with PSA serum levels/nor with PSA and PSAP tissue staining.
