Negative prostatectomy, also radical prostatectomy without cancer, occasionally happens.
General
- Seen in approximately 1% of prostatectomies.[1]
Work-up
- Review biopsy if available.
- Is it plausible?
- Biopsies in negative prostatectomies or minimal cancer prostatectomies usually have a small volume of low grade cancer.
- A negative prostatectomy with high-grade cancer on biopsy or a large volume of disease on biopsy should prompt identity testing.[2]
- Is it plausible?
- Submit prostate in total (if not already done).
- Levels (x3) on all prostate blocks.[1]
- Flip the (prostate tissue) blocks and do levels (x3).[1]
