Does the New Proposal for Prostate Cancer Grading Correlate With CAPRA Score?

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Prostate cancer (PCa) grading is crucial for determining prognosis and treatment.
• The International Society of Urological Pathology (ISUP) proposed a new Gleason grading system.
• The Cancer of the Prostate Risk Assessment (CAPRA) score is a validated tool for predicting PCa outcomes.

Purpose of the Study:

• To evaluate the correlation between the new ISUP Gleason grading system and the CAPRA score in patients undergoing radical prostatectomy.

Main Methods:

• Retrospective review of 146 patients who underwent radical prostatectomy between 2007 and 2013.
• Data collected included patient demographics, biopsy Gleason Score (GS), and pre- and post-operative PSA values.
• Correlation analysis was performed between the new ISUP Gleason grading system and CAPRA scores.

Main Results:

• The study included 146 patients with a mean age of 66.6 years.
• A significant positive correlation was found between the new ISUP Gleason grading system and the CAPRA score (Correlation Coefficient=0.361, P < 0.001).

Conclusions:

• The newly proposed ISUP Gleason grading system is significantly correlated with the CAPRA score.
• Both grading systems should be considered by clinicians for predicting prostate cancer prognosis.
