Standards for prostate biopsy

Preparation of prostate specific antigen standards for immunoradiometric assay

Background: Immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (PSA) in clinical laboratories. Usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. Thus in order to avoid these problems the artificial matrix was used which acts sim...

Stereotactic transperineal prostate biopsy.

This study investigates the detection rate of nonpalpable, isoechoic occult prostate malignancy using a stereotactic transperineal prostate biopsy (STPB) technique in patients with a previously negative transrectal ultrasound-guided prostate biopsy.

Geometric systematic prostate biopsy.

OBJECTIVE The common sextant prostate biopsy schema lacks a three-dimensional (3D) geometric definition. The study objective was to determine the influence of the geometric distribution of the cores on the detection probability of prostate cancer (PCa). METHODS The detection probability of significant (>0.5 cm3) and insignificant (<0.2 cm3) tumors was quantified based on a novel 3D capsule mo...
