Purpose
Radical prostatectomy is performed after cancer has been found by needle core biopsy or less commonly,when the gland is severely hypertrophied due toBPH.Most prostatectomiesperformed here arerobot assisted-laparoscopic(otherwise known as Da Vinci prostatectomy). The open prostatectomyprocedure israrely used.The Da Vinci techniqueismuch less invasive, decreasing recovery time, infection,and bleeding.
Orientation tip: the seminal vesicles and vasadeferentiaare attached to the baseon the superior-posterior aspect!
Procedure
- Measure: length x width xheight
- Weight
- Measure both left/right vas deferens and left/right seminal vesicles
- Ink:ALWAYSINKTHE PROSTATEIN THEFOLLOWING SCHEME:
- GREEN-RIGHTHALF
- BLUE-LEFT HALF
- YELLOW-Prostate/BLADDER
- RED– false margin under staple line (see below)
- BLACK– Anterior aspect of DUM
- (this also includes left and right seminal vesicles and vas deferens).The anterior margin is inked black(required fordistal apex margins sections- see below for details).
- Cassette Key (see template below):Start with rightsectionsfollowed byleft.
- Please see the“Whole mount Prostate grossing template”for details of cassettedesignations and followthem.
- Double check to make sure that cassette numbers have correct accession and part numbers.
- Staples:Almost all prostatectomies contain sutures ormultiple staples onthe anterior aspect.
- Always ink the specimen first, and then remove thestaples.
- Ink the exposed parenchyma with red ink to denote the false margin.
- Note this in the comment section of the template.
- Pleasesee a power-point“Whole Mount Prostates”inthecuttingmanualfor figures
- SV and VD:Amputatethe seminalvesicles and the vas deferens at the base.
- Seriallysection forabnormalities
- PlaceR and Lseminal vesicletissue at the point ofattachmentto prostatein the assigned cassette(basemost section of eachseminal vesicle).
- Proximal Urethral Margin (PUM):Transect bladder base(proximal urethral margin, PUM) andradially section around urethra
- submit in 4 cassettes labelled:
- Ant RightPUM
- Ant Left PUM
- Post RightPUM
- Posterior LeftPUM
- Distal Urethral Margin:Transect apex(distalurethral margin DUM) and section radiallyaround theurethra(likeacervical cone).
- Inkthe anterioraspect oftheapex withblackink (ifnot done earlier).
- Submit in two cassettes:
- Right DUM
- Left DUM
- Sections:Sectionthe remaininggland from base to apex (anterior to posterior) atapproximately 5mm thickness,taking care to retain inkedmargins.
- Remove any residual staples or calculi
- Lay out all the slices in proper order from base to apex, with basemost whole mount sectionconsidered as slice 1(seethe power –point for images).
- Whole Mount:Every other slice will be submittedin a WM,alwaysincluding the last.
- Example:Aprostate with 7 sections: 1, 3, 5 and 7 will be submittedas whole mount sections.
- Example:A prostate with 8 sections: 1, 3, 5, 7 and 8 will be submittedas whole mount sections.
- Capsule:For the remaining/intervening slices, core out the central prostate and submit the capsulesections
- i.e.fortheseinterveningsections, the entire capsule must be submitted for extraprostatic extension and margin evaluation.
- THE ENTIRE CAPSULE MUST BE SUBMITTED ON ALL PROSTATECTOMIES, WHETHEROR NOTTHEY HAVE BEEN PROCURED ON.
- Each cassette will contain two sections of the capsule
- (i.e., right anterior capsule and left anterior capsule of section 2 can be placed in one cassette because they will be inked differently).
- On procured prostates, the central portions of these capsule sections MUST be banked for research; on non-procured prostates, the central portion will simply not be submitted.
- Procured Prostates:The prostate will have been grossed while fresh;all sections must then be pinned out and fixed before being submitted.Responsibility for submitting these sections after fixation will depend oncommunication between the PAs and residents.
TIP: How is grossing different for urothelial carcinoma versus prostate carcinoma?
- Cystectomy orCystoprostatectomywill be performed
- Submit the distal urethral margin (DUM)enface/shave.) (NOT as perpendicular margin sections.
- Occasionally the surgeon will have already submitted a separate specimen as the DUM, in which case you do not have to submit another shave/enface section
