Summary

Prostate-specific antigen (PSA) velocity is a useful indicator for detecting prostate cancer after subcapsular prostatectomy. Elevated postoperative PSA velocity suggests malignancy in patients who underwent the procedure.

Area of Science:

  • Urology
  • Oncology
  • Medical Diagnostics

Background:

  • Subcapsular prostatectomy is a surgical procedure for benign prostatic hyperplasia.
  • Prostate-specific antigen (PSA) is a biomarker for prostate cancer.
  • Evaluating PSA screening post-surgery is crucial for patient management.

Purpose of the Study:

  • To assess the effectiveness of prostate-specific antigen (PSA) screening in identifying prostate cancer following subcapsular prostatectomy.
  • To determine if PSA velocity can predict prostate cancer in this patient cohort.

Main Methods:

  • Retrospective analysis of 41 patients undergoing subcapsular prostatectomy over 15 years.
  • Patients classified as benign or malignant based on surgical specimen or follow-up diagnosis.

  • Collected data included PSA levels, prostate volume, and pathology; PSA velocity was calculated.

    • Main Results:

    • 31 patients with adequate data were analyzed; 6 (19%) were diagnosed with prostate cancer.
    • Postoperative PSA velocity was significantly higher in the malignant group (1.22 ng/mL/yr) vs. benign group (0.06 ng/mL/yr).
    • Elevated PSA velocity correlated with confirmed prostate cancer diagnoses.

    Conclusions:

    • Elevated PSA velocity after subcapsular prostatectomy is indicative of prostate cancer.
    • PSA velocity can aid in differentiating between benign and malignant outcomes post-procedure.
    • This finding supports the utility of PSA monitoring in patients after subcapsular prostatectomy.
