Robotically assisted laparoscopic radical prostatectomy induces lower tissue trauma than radical retropubic...

Area of Science:

• Urology
• Surgical Oncology
• Immunology

Background:

• Radical prostatectomy is a standard treatment for prostate cancer.
• Comparing surgical techniques is crucial for optimizing patient outcomes.
• Inflammatory mediators can serve as biomarkers for tissue trauma.

Purpose of the Study:

• To compare tissue trauma between Retropubic Radical Prostatectomy (RRP) and Robotically Assisted Laparoscopic Radical Prostatectomy (RALP).
• To evaluate differences in inflammatory mediator levels post-surgery.
• To determine if RALP results in less tissue trauma compared to RRP.

Main Methods:

• Serum samples were collected from 40 RALP patients and 20 RRP patients at four time points.
• Cytokines IL-4, IL-8, IL-6, IL-1B, IL-10, and TNF-α were measured using ELISA/Multiplex assays and xMAP-Luminex®.
• Statistical analysis was performed to compare mediator levels between surgical groups and time points.

Main Results:

• Interleukin-10 (IL-10) and Interleukin-6 (IL-6) levels were significantly higher at T4 compared to T1-T3 in both groups (p=0.001).
• IL-10 and IL-6 were significantly higher at T4 in the RRP group compared to the RALP group (p=0.000 and p=0.001, respectively).
• These findings suggest a more pronounced inflammatory response in RRP.

Conclusions:

• RALP appears to cause less tissue trauma than classical RRP.
• The limited increase in inflammatory mediators, specifically IL-6 and IL-10, supports the hypothesis that RALP is less traumatic.
• Further research can explore long-term outcomes and other inflammatory markers.
