Objective:
The aim of our study is to correlate the CT adipose tissue distribution and recurrence risk of Prostatic Cancer (PCa) after Radical Prostatectomy (RP). Furthermore, we evaluated the association of adipose tissue and PCa aggressiveness.
Materials And Methods:
We identified two groups of patients based on presence (group A) and absence (group B or control group) of Bio-chemical Recurrence (BCR) after RP. A semi-automatic function able to recognize the typical attenuation values of adipose tissue was used for sub-cutaneous (SCAT), visceral (VAT), total (TAT) and periprostatic (PPAT) adipose tissues. For both groups of patients, a descriptive analysis of continuous variables and categorical variables was performed.
Results:
After comparing between groups, a statistically significant difference was found for VAT (p<0.001) and for VAT/TAT ratio (p=0.013). No statistically significant correlation was found for PPAT and SCAT, even if higher values were found in patients with high grade tumors.
Conclusion:
This study confirms visceral adipose tissue as a quantitative imaging parameter related to oncological risk of PCa recurrence development, and the role of abdominal fat distribution measured with CT before RP as an important tool to predict the PCa recurrence risk, particularly in patients with high grade tumors.
