Negative prostatectomy, also radical prostatectomy without cancer, occasionally happens.

General

  • Seen in approximately 1% of prostatectomies.[1]

Work-up

  1. 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]
  2. Submit prostate in total (if not already done).
  3. Levels (x3) on all prostate blocks.[1]
  4. Flip the (prostate tissue) blocks and do levels (x3).[1]
