Introduction
Prostate chips are generated from transurethral resection of the prostate (TURP) procedures. These are generally for relieving urinary obstruction due to nodular hyperplasia of the prostate (benign prostatic hyperplasia); however, urinary obstruction may be secondary to prostate cancer. Thus, the job of the pathologist here, usually, is excluding an incidental cancer.
The prevalence of prostate cancer varies from 7% (in a series 823 TURPs[1]) to 17% (in an older series of 747 TURPs[2]).
Clinically relevant cancer in procedures done for BPH (TURPs and prostatectomies) is seen in approximately 1.5% of specimens.[1]
Protocol
Specimen:
- Weight ___ grams.
- Dimensions (in aggregate): ___ x ___ x ___ cm.
- Number of fragments: [1-6 / multiple (>6)].
- Appearance: [tan-gray / yellow / orange].
- Consistency: [rubbery / firm].
- Other: [none / hemorrhagic appearance / necrotic appearing].
[Submitted in total/Representative sections submitted] in block(s) ___.
Protocol notes
Number of cassettes:[3]
- <= 12 grams: EIT.
- >12 grams: embed 12 grams and 1 cassette for every additional 5 grams.
- If the prostate chips have a mass of:
- 16 grams: 6-8 cassettes for 12 grams + 1 cassette = 7-9 cassettes.
- 21 grams: 6-8 cassettes for 12 grams + 2 cassettes = 7-9 cassettes.
- If the prostate chips have a mass of:
What to look for/feel for:[3]
| Entity | Colour | Firmness |
|---|---|---|
| Prostate cancer | yellow/orange | firm |
| Benign prostate | tan/gray | rubbery |
