Partial versus radical nephrectomy in patients with adverse clinical or pathologic characteristics

Area of Science:

• Urology
• Oncology
• Nephrology

Background:

• Partial nephrectomy (PN) and radical nephrectomy (RN) are surgical options for renal cell carcinoma (RCC).
• Assessing oncological outcomes for PN in complex cases is crucial for treatment selection.

Purpose of the Study:

• To evaluate cancer-specific survival rates after PN versus RN for large (>= 7 cm) or pathologically unfavorable RCC.
• To compare outcomes for stage pT3a or Fuhrman grades III-IV RCC treated with PN versus RN.

Main Methods:

• Retrospective analysis of 4072 nephrectomies (PN or RN) for RCC across 13 centers (1984-2001).
• Matched survival analyses compared PN and RN for tumors > 7 cm, Fuhrman grades III-IV, or pT3a stage.
• Exclusion of patients with nodal or distant metastases.

Main Results:

• PN for tumors > 7 cm was linked to significantly higher cancer-specific mortality compared to RN (HR=5.3, P=.025).
• No significant differences in cancer-specific survival were observed between PN and RN for Fuhrman grades III-IV (HR=0.7, P=.5) or pT3a lesions (HR=2.5, P=.9).

Conclusions:

• PN may compromise cancer control for large renal tumors (>= 7 cm).
• PN provides comparable cancer control to RN for patients with unfavorable pathology (Fuhrman grades III-IV or pT3a stage).
