Thermal ablation in renal cell carcinoma: what affects renal function?

Area of Science:

• Nephrology
• Oncology
• Minimally Invasive Surgery

Background:

• Thermal ablation is a minimally invasive treatment for renal cell carcinoma (RCC), especially for patients unsuitable for surgery.
• It is considered a viable alternative to nephron-sparing surgery, with many studies reporting minimal impact on renal function.

Purpose of the Study:

• To review factors influencing renal function reduction after thermal ablation for RCC.
• To evaluate the correlation between local tumor control and preserved renal function.

Main Methods:

• Literature review of studies on thermal ablation for renal cell carcinoma.
• Analysis of factors affecting renal function post-ablation, including tumor characteristics and ablation techniques.

Main Results:

• Achieving local tumor control often necessitates ablating normal renal parenchyma, leading to reduced renal function.
• The extent of renal function reduction is influenced by tumor size, location, number, and the specific ablation method used.

Conclusions:

• While thermal ablation is effective for RCC, careful consideration of the trade-off between tumor control and renal function preservation is crucial.
• Further research is needed to fully elucidate the determinants of renal function decline following thermal ablation therapies.
