Summary
Transrectal prostatic ultrasonography reliably quantifies tumor volume decrease post-therapy and improves staging accuracy for localized prostate cancer. This diagnostic tool aids in assessing treatment response and detecting capsular involvement.
Area of Science:
- Urology
- Medical Imaging
Background:
- Prostate cancer diagnosis and staging are critical for effective treatment planning.
- Accurate assessment of tumor response to therapy is essential for patient management.
Purpose of the Study:
- To evaluate the reliability of transrectal prostatic ultrasonography in assessing treatment response.
- To determine the value of transrectal prostatic ultrasonography in staging localized prostate cancer, particularly for detecting capsular involvement.
Main Methods:
- Transrectal prostatic ultrasonography was performed in 203 patients over one year.
- Tumor volume changes were quantified post-therapy in patients with available long-term follow-up.
- Capsular involvement was assessed in 12 patients prior to radical prostatectomy.
Main Results:
- Transrectal prostatic ultrasonography demonstrated reliability in quantifying tumor volume decrease following therapy in 71% of evaluable prostate cancer patients (10/14).
- The modality was highly valuable in detecting capsular involvement in 12 patients staged before radical prostatectomy.
Conclusions:
- Transrectal prostatic ultrasonography is a reliable tool for monitoring treatment response by measuring tumor volume reduction.
- This imaging technique significantly enhances staging capabilities for localized prostate carcinoma, aiding in surgical planning and prognosis.
