Predictive preoperatory variables of the prostate tumor volume

Area of Science:

• Urology
• Oncology
• Medical Imaging

Background:

• Prostate cancer (PCa) is a leading malignancy in men globally.
• Accurate preoperative tumor volume estimation is crucial for treatment decisions, particularly for radical prostatectomy (RP).
• Identifying smaller, less aggressive tumors can help avoid immediate radical prostatectomy.

Purpose of the Study:

• To evaluate preoperative variables for predicting final tumor volume after radical prostatectomy (RP).
• To develop a practical scoring system for prospective prostate cancer (PCa) volume evaluation.

Main Methods:

• Analysis of 128 prostate cancer (PCa) cases.
• Evaluation of preoperative variables: patient age, prostate volume (ultrasound), serum PSA, number of positive biopsies, tumor size, tumor length percentage, and Gleason score.
• Development and statistical validation of a predictive scoring system.

Main Results:

• Several preoperative variables were assessed for their correlation with final tumor volume.
• A statistically validated scoring system combining Gleason score, number of positive biopsies, and tumor length percentage was developed.
• This system demonstrated a significant correlation and predictive capability for prostate cancer (PCa) tumor volume.

Conclusions:

• The developed scoring system offers a practical and effective method for prospective prostate cancer (PCa) volume evaluation.
• This tool can aid clinicians in refining treatment strategies by better estimating tumor volume preoperatively.
• The findings contribute valuable insights into the preoperative assessment of prostate cancer (PCa).
