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.

Treatment: Surgery
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
