Intra-operative prostate examination (IOPE) identifies abnormalities in 12% of prostate cancer patients. While its predictive value is limited, IOPE may help reduce positive surgical margins in select cases.

Area of Science:

  • Urology
  • Surgical Oncology
  • Pathology

Background:

  • Extraprostatic extension (EPE) is a key prognostic factor in prostate cancer.
  • Accurate intra-operative assessment is crucial for surgical decision-making during radical prostatectomy.

Purpose of the Study:

  • To evaluate the efficacy of intra-operative prostate examination (IOPE) in predicting EPE.
  • To assess the impact of IOPE combined with wide neurovascular bundle (NVB) excision on positive surgical margin (PSM) rates.

Main Methods:

  • Retrospective review of 403 patients with clinical stage T1c prostate adenocarcinoma undergoing radical retropubic prostatectomy (RRP).
  • IOPE performed during RRP; wide excision of NVB for palpable abnormalities.
  • Analysis of pathological outcomes, including EPE and PSM.

Main Results:

  • IOPE detected abnormalities in 12% of patients (49/403).
  • EPE confirmed in 37% of these cases after wide excision; only 6% had PSM.
  • In patients with normal IOPE and NVB preservation, EPE occurred in 30/354 (8.5%), with a 23% PSM rate.

Conclusions:

  • IOPE identifies a subset of patients with potential EPE.
  • IOPE, when combined with NVB wide excision, may reduce PSMs in these patients.
  • IOPE remains valuable for assessing EPE risk and guiding surgical management.
