Smaller prostate size predicts high grade prostate cancer at final pathology

Area of Science:

• Urology
• Oncology
• Pathology

Background:

• Prostate size is a factor that may influence the detection of high-grade prostate cancer.
• Understanding this relationship is crucial for accurate diagnosis and treatment planning.

Purpose of the Study:

• To evaluate the association between prostate size and the detection of high-grade prostate cancer (Gleason score 7 or greater).

Main Methods:

• Analysis of data from 2,880 patients who underwent prostatectomy for prostate cancer.
• Comparison of prostate size with clinical variables and pathological outcomes.
• Multivariate logistic regression to assess prostate size as a predictor of high-grade cancer.

Main Results:

• Smaller prostate size was significantly associated with high-grade prostate cancer, extraprostatic extension, and positive surgical margins.
• The probability of high-grade disease decreased with increasing prostate size.
• Prostate size was an independent predictor of high-grade disease (OR 0.94 per 2 gm increment, p <0.001).

Conclusions:

• Prostate size is inversely associated with the risk of high-grade prostate cancer at final pathology.
• Prostate size can aid in predicting the likelihood of detecting high-grade prostate cancer, potentially impacting patient management strategies.
