Histopathologic Review of Previously Negative Prostatic Core Needle Biopsies Following a New Diagnosis of Adenocarcinoma of the Prostate by Core Needle Biopsies: Implications for Quality Assurance Programs
Programs for quality assurance are increasingly important in surgical pathology. Many quality assurance (QA) techniques for surgical pathology were adopted from procedures introduced in cytopathology. Surgical pathology specimens have diminished in size such that the majority of diagnostic biopsies of prostatic lesions are now core needle biopsies. These specimens raise issues similar to those ...
متن کاملComparison of Matrix Metalloproteinases 2 mRNA Expression in Prostatic Adenocarcinoma and Benign Prostatic Hyperplasia
