Radiofrequency ablation of papillary thyroid microcarcinoma

Area of Science:

• Endocrinology
• Oncology
• Minimally Invasive Surgery

Background:

• Papillary thyroid microcarcinoma (PTMC) is a small thyroid cancer (≤1 cm) with an indolent course.
• Optimal management strategies for PTMC are debated, including surgery, active surveillance, and thermal ablation.
• Conventional surgery, while effective, can lead to overtreatment and complications.

Purpose of the Study:

• To provide a comprehensive analysis of PTMC management options: surgical resection, active surveillance, and image-guided thermal ablation.
• To compare the indications, outcomes, and limitations of each management strategy.
• To highlight radiofrequency ablation (RFA) as an emerging therapeutic tool.

Main Methods:

• Review of current literature on PTMC management strategies.
• Critical comparison of efficacy, safety profiles, and patient selection criteria for surgery, active surveillance, and RFA.
• Analysis of outcomes, including local tumor control, morbidity, and cosmetic results.

Main Results:

• Surgery offers complete tumor excision but risks overtreatment and complications.
• Active surveillance is a conservative option for low-risk PTMC, reducing interventions but requiring long-term follow-up.
• Radiofrequency ablation (RFA) demonstrates growing evidence as a safe and effective minimally invasive technique for selected PTMC patients, achieving local control with minimal morbidity.

Conclusions:

• Radiofrequency ablation (RFA) is an emerging therapeutic tool for PTMC, offering a balance between surgical intervention and observation.
• RFA provides a minimally invasive option with favorable outcomes for selected PTMC cases.
• Individualized treatment approaches are crucial for optimal PTMC management, considering patient-specific factors and risk stratification.
