Principles of nephrectomy for malignant disease

Area of Science:

• Uro-oncology
• Surgical Oncology
• Nephrology

Background:

• The transperitoneal approach was historically favored for radical nephrectomy in renal cell carcinoma (RCC) to control renal vessels early.
• This approach aimed to minimize tumor cell dissemination during surgery, based on retrospective data.
• However, recent evidence suggests potential benefits of the extraperitoneal (translumbar) approach for RCC, including reduced morbidity.

Purpose of the Study:

• To evaluate the oncological efficacy and morbidity of different surgical approaches for renal cell carcinoma (RCC).
• To address the limitations of retrospective data and the need for robust evidence regarding surgical techniques in RCC management.
• To explore advancements in systemic therapy and combined treatments for advanced-stage RCC.

Main Methods:

• Review of existing retrospective data comparing transperitoneal and extraperitoneal approaches for radical nephrectomy.
• Analysis of oncological outcomes and patient morbidity associated with each surgical technique.
• Discussion of the need for large, randomized multicenter trials to confirm findings.

Main Results:

• The transperitoneal approach was the historical standard for RCC surgery.
• The extraperitoneal approach may offer comparable oncological efficacy with reduced morbidity.
• Current evidence is largely retrospective or statistically insignificant, precluding firm conclusions.

Conclusions:

• Further large-scale randomized trials are necessary to definitively compare surgical approaches for RCC.
• Improvements in RCC survival may depend on systemic therapies and combined treatment strategies.
• Surgical intervention remains crucial, especially with the rise of immunotherapeutic strategies in uro-oncology.
