Abstract

Insights

Kidney tumor ablation shows high local control rates (88%-100%) in patients with advanced chronic kidney disease (CKD). While effects on CKD progression are unclear, ablation offers a viable treatment option for these patients.

Area of Science:

  • Nephrology
  • Oncology
  • Interventional Radiology

Background:

  • Patients with advanced chronic kidney disease (CKD) often have limited treatment options for kidney tumors.
  • Kidney tumor ablation is a minimally invasive technique with potential benefits for organ preservation.

Purpose of the Study:

  • To review the current status and outcomes of kidney tumor ablation in patients with significant kidney impairment, specifically stage 4 or 5 CKD.

Main Methods:

  • Literature review of recently published reports on kidney tumor ablation in patients with CKD.
  • Analysis of local tumor control rates and impact on kidney function.

Main Results:

  • Prevalence of stage 4-5 CKD patients undergoing ablation ranges from 2.0% to 10%.
  • Local tumor control rates in these patients are high, between 88% and 100%.
  • The impact of ablation on CKD progression remains unclear, with observed kidney function changes possibly related to the procedure or natural disease course.

Conclusions:

  • Kidney tumor ablation can achieve complete tumor removal while potentially preserving kidney function in patients with advanced CKD.
  • Despite uncertainties regarding CKD progression, ablation represents a crucial treatment option given limited alternatives.
  • Active surveillance is also a guideline-recommended option for these patients.
