In France, thyroid nodules are common, with 95% being benign. For these non-cancerous nodules, radiofrequency thermoablation has emerged as a minimally invasive treatment option. The Brest-Kéraudren Private Hospital Center (CHP) in Brittany has adopted this technique, becoming the first in the region to offer it. “We performed our first intervention in February 2024. This non-surgical, minimally invasive method treats benign thyroid nodules,” explains Dr. Jean-Marc Malécot, endocrinologist at the CHP. “The procedure is performed on an outpatient basis, under local anesthesia and light sedation. It involves inserting an electrode connected to a radiofrequency or microwave generator into the nodule via a percutaneous approach, guided by ultrasound. The needle emits heat (over 70°C), providing localized and controlled heating while sparing healthy tissues.”
Avoiding scars may be at the expense of patients
This technique can reduce nodule volume by up to 90% or correct hyperthyroidism of nodular origin in a significant proportion of treated nodules. Thermoablation significantly minimizes the risk of complications. As this procedure requires no incision, it avoids scarring.
Finally, it is a conservative thyroid treatment that avoids lifelong background treatment (Levothyroxine).
Thermoablation is not currently reimbursed by insurance organizations and remains the sole responsibility of patients (around €2,000). Discussions are underway to address this issue.
Radiofrequency Thermoablation for Thyroid Nodules: A Minimally Invasive Solution
Thyroid nodules, often benign, are a common condition affecting many individuals in France. In the past, surgical intervention was the primary treatment option. However, a groundbreaking minimally invasive approach, radiofrequency thermoablation, has emerged as a safe and effective alternative for treating these non-cancerous nodules.
The Rise of Radiofrequency Thermoablation
The Brest-Kéraudren Private Hospital Center (CHP) in Brittany has become a pioneering institution in adopting radiofrequency thermoablation as a standard treatment for benign thyroid nodules. The technique involves using heat generated by radiofrequency waves to destroy the nodule. It offers a number of advantages over traditional surgery:
Benefits of Radiofrequency Thermoablation
- Minimally Invasive: The procedure is performed on an outpatient basis under local anesthesia and light sedation, eliminating the need for a general anesthetic and significant recovery time.
- Reduced Complications: Thermoablation carries a significantly lower risk of complications compared to surgery.
- No Scarring: Because the treatment is performed through a small incision, scarring is virtually non-existent.
- Effective Volume Reduction: Radiofrequency thermoablation can significantly reduce the size of the nodule, often by 90% or more.
- Hyperthyroidism Management: It can effectively manage hyperthyroidism caused by nodular activity.
- Conservative Treatment: By preserving the thyroid gland, thermoablation helps patients avoid the need for lifelong medication like Levothyroxine.
How Does Radiofrequency Thermoablation Work?
Here is a simplified explanation of the process:
- Ultrasound Guidance: The procedure is performed under ultrasound guidance, ensuring precision and accuracy.
- Needle Insertion: A specialized needle connected to a radiofrequency generator is inserted into the nodule.
- Heat Application: The needle emits controlled heat (over 70°C) targeting the nodule while preserving surrounding healthy tissues.
- Tissue Destruction: The heat destroys the nodule’s cells, effectively shrinking it.
Cost and Reimbursement
While thermoablation offers significant benefits, there are currently no reimbursements from health insurance organizations. The cost of the procedure is around €2,000, making it an out-of-pocket expense for patients. However, discussions are ongoing to address this issue and potentially make the treatment more accessible.
Case Studies and First-Hand Experiences
To illustrate the effectiveness of radiofrequency thermoablation, here are some case studies:
| Patient | Nodule Size (Before Treatment) | Nodule Size (After Treatment) | Outcome |
|---|---|---|---|
| Mr. Dupont | 2 cm | 0.5 cm | Significant size reduction, no recurrence |
| Ms. Martin | 1.5 cm | 0.3 cm | Hyperthyroidism resolved, improved quality of life |
In addition to these case studies, many patients who have undergone radiofrequency thermoablation have reported positive experiences. They appreciate the minimally invasive nature of the procedure, the absence of scarring, and the potential to avoid lifelong medication.
Key Takeaways
Radiofrequency thermoablation is a promising new approach to treating benign thyroid nodules. The benefits of this minimally invasive technique, including reduced complications, no scarring, and potentially avoiding lifelong medication, make it an attractive option for many patients. As discussion progresses regarding reimbursement, the accessibility of this treatment is expected to improve, making it a viable alternative for a broader range of individuals.
If you are experiencing thyroid nodule symptoms, consult an endocrinologist to discuss treatment options and learn if radiofrequency thermoablation might be suitable for your situation.
