Summary

Renal ablation (RA) shows similar long-term efficacy to surgery for kidney tumors, but may require re-treatment more often. Careful consideration of follow-up, tumor type, and technique is crucial for interpreting results.

Area of Science:

  • Oncology
  • Urology
  • Minimally Invasive Surgery

Background:

  • Renal ablation (RA) is increasingly used beyond palliative care for kidney tumors.
  • Limited studies report long-term outcomes (≥5 years) for RA.
  • Existing literature presents significant biases and discrepancies.

Purpose of the Study:

  • To critically evaluate the long-term oncologic efficacy of renal ablation techniques.
  • To identify key factors influencing RA outcomes and recurrence rates.
  • To compare RA with traditional surgical excision for kidney tumors.

Main Methods:

  • Systematic review and meta-analysis of studies reporting ≥5-year follow-up for RA.
  • Analysis of tumor characteristics, ablation modalities (radiofrequency ablation [RFA], cryoablation), and practitioner experience.
  • Comparison of local recurrence rates between RA and surgical excision.

Main Results:

  • Long-term oncologic efficacy of RFA and cryoablation appears comparable.
  • Percutaneous RFA may require re-ablation more frequently than other RA techniques.
  • RA is associated with a slightly higher rate of local recurrence compared to surgical excision.

Conclusions:

  • Renal ablation offers a viable alternative for kidney tumor treatment with comparable long-term efficacy to surgery.
  • Interpreting RA outcomes necessitates careful consideration of follow-up duration, tumor specifics, technique, and practitioner expertise.
  • While effective, RA may have higher local recurrence rates, underscoring the need for precise technique and patient selection.
