Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
prostate cancer diagnosis via systematic TRUS-guided prostate biopsy (once per patient, lasting ~ 20 min):

- prostate samples are harvested via systematic TRUS-guided biopsy using a Bard MAGNUM (Registered trademark) biopsy gun (Bard Biopsy Systems Inc., Tempe, AZ, USA) and 18G x 20 mm core tissue biopsy needles;
- local anesthesia is achieved by intrarectal application of 2% lidocaine gel, without periprostatic nerve block;
- in selected cases antibiotic prophylaxis is used, consisting in single dose fluoroquinolone derivatives or amoxicillin administered before the procedure;
- up to 14 biopsy cores per patient are extracted and placed in a HistoBest Biopsy Chip (Trademark) matrix in grooves at specified positions and in the same orientation with respect to the entry point of the biopsy needle;
- the location of each core is marked with a number on a prostate diagram map for each biopsy protocol sheet, allowing unambiguous and easy location of the tumor and estimation of its size and extension.

Comparator / control treatment
histopathology examination + immunohistochemistry for p63 and Alpha-Methylacyl-CoA Racemase (AMACR) primary antibodies (once only per patient, lasting 3 days):

- processing of biopsy-loaded matrices is performed in a standardized fashion, and consists in: fixation for 24 +/- 2 hours with 0.2 M phosphate-buffered 4% formaldehyde (pH 7.5), dehydration in graded ethanols, optional storage in buthanol, clarifying in transition solvents, infiltration and embedding in paraffin, semi-serial sectioning at 4-5 mm, mounting on positively charged glass slides, and classical hematoxylin-eosin or immunohistochemistry staining

Summary
Brief summary
The primary purpose of the trial is to assess the effectiveness and safety of a new method for parallel harvesting, processing and analysis of prostate biopsy cores using a new grooved organic matrix, HistoBest Biopsy Chip(TM) (patent pending).
The current hypothesis is that use of this matrix will improve prostate cancer histopathology diagnosis, in several ways:
- by facilitating and encouraging a systematic biopsy approach
- by reducing time and material expenses in processing and analysis of histopathology samples
- by allowing a precise location of the tumor and its extension, because information pertaining to the location and orientation of each biopsy core within the prostate is preserved.

Another goal of the study is to establish a comprehensive tissue archive in view of further studies, such as screening for retroviruses, genetic susceptibility and somatic mutations in prostate cancer.
