Summary
Image-guided thermal ablation offers effective treatment for symptomatic benign thyroid nodules, with radiofrequency ablation and laser ablation showing significant volume reduction. These minimally invasive techniques are increasingly becoming a preferred alternative to surgery.
Area of Science:
- Endocrinology
- Interventional Radiology
- Oncology
Background:
- Benign thyroid nodules are common, often asymptomatic, and typically require no treatment.
- Symptomatic thyroid nodules traditionally necessitate surgical excision.
- Image-guided percutaneous thermal ablation has emerged as a promising alternative for symptomatic nodules.
Purpose of the Study:
- To review the current literature on image-guided percutaneous thermal ablation for benign thyroid nodules.
- To compare the efficacy of different ablation techniques, including radiofrequency (RFA), laser ablation (LA), microwave ablation (MWA), and high-intensity focused ultrasound (HIFU).
Main Methods:
- Literature review of studies on image-guided percutaneous thermal ablation for benign thyroid nodules.
- Focus on techniques: radiofrequency ablation (RFA), laser ablation (LA), microwave ablation (MWA), and high-intensity focused ultrasound (HIFU).
- Discussion of advanced imaging guidance modalities like contrast-enhanced ultrasound and virtual navigation with fusion imaging.
Main Results:
- Radiofrequency ablation (RFA) demonstrates significant thyroid nodule volume reduction, ranging from 47-84% at 3-6 months and 62-93% at 1 year.
- Laser ablation (LA) also shows effectiveness, with volume reduction between 37-81% at 3-6 months and 13-82% at 1 year.
- Limited evidence currently exists for the efficacy of microwave ablation (MWA) and high-intensity focused ultrasound (HIFU).
Conclusions:
- Image-guided percutaneous thermal ablation, particularly RFA and LA, provides effective treatment for symptomatic benign thyroid nodules.
- These minimally invasive techniques offer significant nodule shrinkage and are increasingly considered first-line options.
- Advancements in imaging guidance enhance the precision and potential outcomes of these ablation procedures.
