Microwave ablation compared to thyroidectomy to treat benign thyroid nodules

Area of Science:

• Endocrinology
• Minimally Invasive Procedures
• Surgical Oncology

Background:

• Benign thyroid nodules are common and often asymptomatic.
• Symptomatic nodules may require treatment, with surgery historically being the standard.
• Emerging technologies like microwave ablation (MWA) offer alternatives to traditional surgery.

Purpose of the Study:

• To compare the efficacy, tolerability, and cost-effectiveness of MWA versus surgical treatment for symptomatic benign thyroid nodules.
• To evaluate nodule volume reduction, patient outcomes, and complication rates between MWA and surgery.

Main Methods:

• A prospective randomized trial involving 52 patients with symptomatic benign thyroid nodules.
• Patients were assigned to either MWA or surgical treatment.
• Key parameters assessed included volume reduction ratio, thyroid function, complications, health-related quality of life (HRQoL), and costs.

Main Results:

• MWA achieved significant nodule volume reduction (up to 92.4% at 12 months), comparable to surgery.
• MWA demonstrated a favorable safety profile with fewer complications and less reported pain than surgery.
• Patients undergoing MWA experienced shorter hospital stays, smaller scars, and quicker recovery, with improved general and mental health scores.

Conclusions:

• Microwave ablation is a highly effective treatment for benign thyroid nodules, yielding substantial volume reduction.
• MWA offers advantages over surgery, including improved cosmetic outcomes, reduced patient discomfort, and lower overall costs.
• MWA represents a safe and effective alternative to surgery for managing symptomatic benign thyroid nodules.
