Partial nephrectomy versus radical nephrectomy for clinical localised renal masses

Area of Science:

• Nephrology
• Surgical Oncology
• Urology

Background:

• Partial nephrectomy and radical nephrectomy are surgical options for localized renal cell carcinoma.
• Debate continues regarding the comparative effects of these surgical approaches.
• High-quality studies are needed to inform treatment recommendations.

Purpose of the Study:

• To assess the effects of partial nephrectomy compared with radical nephrectomy for localized renal cell carcinoma.
• To evaluate oncological and safety outcomes of nephrectomy types.

Main Methods:

• A comprehensive literature search was conducted across multiple databases and trial registries.
• One randomized controlled trial comparing partial and radical nephrectomy for small renal masses was included.
• Data extraction and analysis were performed using Review Manager 5.

Main Results:

• The single included trial with 541 participants showed a potential decrease in all-cause mortality with partial nephrectomy (low-quality evidence).
• No significant differences were found in serious adverse events or time-to-recurrence between the two surgical methods (low-quality evidence).
• Limitations included lack of blinding, cross-over, imprecision, and indirectness, precluding subgroup analyses.

Conclusions:

• Partial nephrectomy may be associated with reduced all-cause mortality in localized renal cell carcinoma.
• There appears to be little to no difference in surgery-related mortality, cancer-specific survival, or recurrence rates.
• Further high-quality research is warranted to confirm these findings.
