Summary
Radiofrequency (RF) thermal ablation causes immediate shrinkage in renal tumors. Follow-up imaging should compare to post-ablation tumor size for accurate assessment.
Area of Science:
- Interventional Radiology
- Oncology
- Nephrology
Background:
- Radiofrequency (RF) thermal ablation is a minimally invasive treatment for solid renal tumors.
- Assessing immediate post-treatment changes is crucial for evaluating treatment efficacy.
Purpose of the Study:
- To evaluate immediate changes in solid renal tumor size after radiofrequency (RF) thermal ablation.
- To assess changes on cross-sectional imaging post-treatment.
Main Methods:
- Retrospective review of patients undergoing percutaneous image-guided RF ablation for renal tumors.
- Noncontrast computed tomography (CT) scans were obtained immediately before and after ablation.
- Tumor diameters were measured, and statistical analysis was performed using the paired Student t test.
Main Results:
- Seventy-two renal tumors in 66 patients were analyzed.
- Mean tumor size decreased by 21% (5.4 mm) immediately after RF ablation (P < .05).
- No correlation was found between tumor size/location and the percentage of size decrease.
Conclusions:
- Renal tumors demonstrate immediate size reduction following RF thermal ablation.
- Anticipate tumor involution and compare follow-up imaging to immediate post-ablation measurements.
