Purpose: Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are prevalent urological ailments in elderly males. Numerous clinical studies have revealed an invert association between BPH/prostate size and PCa growth. This study investigates the association between prostate size and total glandular tissue volume of the peripheral zone (GVPZ) using a unique blend of magnetic resonance imaging (MRI) and histo-anatomical imaging technique.
Materials and Methods: Patients were selected who underwent both radical prostatectomy and preoperative MRI scans. MRI scans provided quantitative measurements of prostatic zone dimensions, while histo-anatomical slides yielded quantitative data on glandular density of the peripheral zone (PZ) using imaging software. Integration of MRI and histopathology enabled the assessment of the GVPZ. Statistical analysis identified relationships between total prostate volume (TPV) and GVPZ.
Results: Seventy-two patients were selected and 40 cc was determined to be the optimal cutoff for small-to-moderate versus large prostates. Once the two subgroups in TPV were formed, the relationship between TPV and GVPZ was found to be highly significant (p<0.001).
Conclusions: The combination of MRI and histopathology offers a novel approach for precise quantification of glandular tissue within the prostatic PZ. This study corroborates the hypothesis of PZ compression via an enlarging transition zone in larger BPH prostates, resulting in PZ glandular atrophy. Given that most PCa originates in the PZ, these results shed light on the potential protective role of larger BPH prostates against PCa growth.
