Toxic Nodule RFA

Toxic Thyroid Nodules

A thyroid nodule is an abnormal growth or mass within the thyroid, a butterfly-shaped gland that is located in the front of the neck. Fortunately, approximately 95% of these masses are benign.1 However, this does not always mean that their presence will go unnoticed. In fact, a small nodule or even a group of them (typically benign) can start autonomously producing excess thyroid hormone.

As a consequence, the hyperfunctioning nodule(s) can cause the enlargement of the gland (goiter) and a condition known as hyperthyroidism (overactive thyroid). If a single autonomous nodule is involved in this process, it is known as a toxic thyroid nodule or a toxic adenoma. On the other hand, if more than one nodule is involved it is called a toxic multinodular goiter. Importantly, toxic nodular goiter (TNG) is a broader term that encompasses both conditions2

In general, toxic nodular goiter is a very common cause of hyperthyroidism. In fact, after Graves disease, TNG is the second most common cause of hyperthyroidism in the United States.3 Furthermore, this condition is more common in women than in men (older than 40 years), given that the prevalence rate of palpable nodules is 5-7% and 1-2% respectively.2 Also, TNG is especially prevalent in elderly adults. In fact, most patients with this condition are older than 50 years.2

How is it diagnosed?

Patients with a toxic adenoma or a toxic multinodular goiter commonly present with typical signs and symptoms of hyperthyroidism. These clinical findings are usually the first clue for the diagnosis of this condition. However, some patients (mostly elderly) may present with atypical symptoms (i.e. cardiovascular complications) or even none at all (subclinical hyperthyroidism).  Most importantly, the diagnosis of hyperthyroidism must be confirmed through laboratory blood tests that show high levels of thyroid hormones and a low level of thyroid-stimulating hormone (TSH). Similarly, these tests can also be used for screening in asymptomatic patients.4

Nuclear medicine thyroid scans are usually performed to determine the cause of hyperthyroidism. In essence, these imaging studies use radioactive drugs (iodine-123 or technetium-99m) to assess the functioning of thyroid tissue. For instance, they can detect if there are any areas of the thyroid that are overactive, meaning that they have an abnormally high uptake of the drug. In scan results, a toxic adenoma can appear as a single hyperfunctioning area, whereas a toxic multinodular goiter usually appears as multiple overactive areas (patchy appearance).4 Finally, other imaging modalities, like ultrasonography, can be used to assess and monitor thyroid nodules.

Treatment Options

The goal of treatment for TNG is the rapid and long-lasting elimination of the state of hyperthyroidism. The most common treatment options for hyperthyroidism are antithyroid drugs, radioiodine therapy, and surgery. Additionally, minimally invasive procedures, such as radiofrequency ablation (RFA), have also become available.4 The choice of treatment for TNG will depend on the severity of the hyperthyroidism, coexisting conditions, the presence of contraindications for specific treatment modalities, and the patient’s preferences. 4

Medications

In the treatment of toxic nodules, antithyroid drugs can be prescribed to treat hyperthyroidism. Moreover, beta-blockers can also help diminish hyperthyroidism-related symptoms (i.e. increased heart rate), if present.2 However, these drugs are only useful to temporarily control thyroid hormone production and prevent complications. Given that if this type of treatment is suspended the hyperthyroidism reappears, these medications are more of a bridge to definite therapy as opposed to a final solution for TNG. 2 Additionally, antithyroid drugs can also help control hormone production in preparation for definitive treatments such as surgery or radioactive iodine therapy.

Radioiodine Therapy

Radioiodine therapy is widely used as a definitive treatment for toxic adenoma and toxic multinodular goiter. In fact, it is the most widely used treatment for toxic nodules in the United States.5 This therapy is based on the fact that the thyroid gland takes up almost all the iodine in the body. Thus, when radioactive iodine (I-131) is administered it can accumulate in the overactive gland tissue and destroy it. As a result, toxic nodules can decrease in size and the signs and symptoms of hyperthyroidism can subside (usually within 2-3 months).

Notably, a single dose of this therapy has been shown to reduce goiter size by up to 40% and it usually succeeds in 85-100% of patients with toxic nodular goiter.2 However, a complication known as hypothyroidism (underactive thyroid) can occur in up to 10-20% of patients.2

Possible indications for radioiodine therapy include advanced age, small goiter size, significant coexistent diseases, and prior surgery or scarring of the anterior neck.4 Furthermore, the main contraindications for this procedure are pregnancy, lactation, and coexisting thyroid cancer.4 Importantly, high activity radioiodine therapy can only decrease the size of large goiters by 30-50% and improve compressive symptoms in 46% of the patients. Whereas complete surgical removal of the thyroid achieves a complete resolution of these symptoms in all patients.4

Surgery

Thyroid surgery is one of the definitive treatments for toxic nodules. A thyroidectomy, or the surgical removal of all or part of the gland, might be necessary if other treatments are inappropriate or contraindicated. Possible indications for surgery include signs and symptoms of excessive pressure in the neck by an enlarged thyroid (i.e. difficulty swallowing or breathing), concern for thyroid cancer, failure of radioiodine therapy, and the need for a rapid resolution of the thyrotoxic state (life-threatening condition induced by excessive thyroid hormone secretion).4

Generally, the presence of a toxic adenoma will involve the removal of the entire thyroid lobule that has the lesion. Conversely, a total or near-total thyroidectomy is typically performed if nodules are on both sides of the thyroid (i.e. toxic multinodular goiter). Most importantly, the risk of treatment failure after either procedure is <1%.4 However, there are several important complications of surgery and some can be dependent on the extent of the procedure (i.e. hypothyroidism or underactive thyroid, hypoparathyroidism, vocal cord paralysis).2 

Non-Surgical RFA for Toxic Thyroid Nodules

Promising minimally invasive procedures are available for patients with toxic thyroid nodules. For instance, if long-term medical treatment, surgery, or radioiodine therapy are inappropriate or contraindicated in patients with this condition, a procedure known as radiofrequency ablation (RFA) can be considered as an alternative.4

Radiofrequency Ablation (RFA) is performed by trained interventional radiologists and it uses high-frequency alternating current to create focalized heat and destroy tissue. In TNG, an ultrasound-guided needle electrode is used to specifically target and eliminate the activity of toxic nodules.

A large retrospective multicenter study validated the safety and efficacy of this procedure for treating autonomously functioning nodules. It demonstrated that associated hyperthyroidism improved in all subjects and normalized in 81.8%. Additionally, no hypothyroidism or major complication was noticed during follow-up.6 Similarly, in another study, RFA was compared to surgery in the treatment of nontoxic nodules. It had fewer complications (1% for RFA and 6% for surgery), no resulting hypothyroidism, similar costs to surgery, and an 85% reduction in nodule size.7

Despite promising evidence, additional large scale studies are needed in patients with toxic thyroid nodules before it can be recommended as mainstream.4 Finally, given the complexity of the procedure, the use of RFA should be limited to experienced clinicians that have received extensive training in this technique.

Understanding the condition

What are toxic thyroid nodules?

A toxic nodule is one that autonomously produces excess thyroid hormone — causing hyperthyroidism. One nodule is a toxic adenoma; several are a toxic multinodular goiter.

A thyroid nodule is an abnormal growth or mass within the thyroid, a butterfly-shaped gland located in the front of the neck. Fortunately, approximately 95% of these masses are benign.1 However, this does not always mean their presence will go unnoticed. In fact, a small nodule — or even a group of them (typically benign) — can start autonomously producing excess thyroid hormone.

As a consequence, the hyperfunctioning nodule(s) can cause enlargement of the gland (goiter) and a condition known as hyperthyroidism (overactive thyroid). If a single autonomous nodule is involved, it is known as a toxic thyroid nodule or a toxic adenoma. If more than one nodule is involved, it is called a toxic multinodular goiter.

Getting the diagnosis right

How is a toxic thyroid nodule diagnosed?

Blood tests confirm hyperthyroidism (high thyroid hormones, low TSH), and a nuclear medicine scan shows which nodule is overactive.4

Patients with a toxic adenoma or a toxic multinodular goiter commonly present with typical signs and symptoms of hyperthyroidism, which are usually the first clue to the diagnosis. However, some patients (mostly elderly) may present with atypical symptoms — for example, cardiovascular complications — or even none at all (subclinical hyperthyroidism). Most importantly, the diagnosis of hyperthyroidism must be confirmed through laboratory blood tests that show high levels of thyroid hormones and a low level of thyroid-stimulating hormone (TSH). These tests can also be used for screening in asymptomatic patients.4
Nuclear medicine thyroid scans are usually performed to determine the cause of hyperthyroidism. These imaging studies use radioactive drugs (iodine-123 or technetium-99m) to assess the functioning of thyroid tissue — detecting areas that are overactive, meaning they have an abnormally high uptake of the drug. On scan results, a toxic adenoma appears as a single hyperfunctioning area, whereas a toxic multinodular goiter appears as multiple overactive areas (a patchy appearance).4 Finally, other imaging modalities, like ultrasonography, can be used to assess and monitor thyroid nodules.
Your options

What are the treatment options?

The goal is the rapid, long-lasting elimination of hyperthyroidism. Options are antithyroid drugs, radioactive iodine, surgery — and, increasingly, minimally invasive RFA.4

The goal of treatment for TNG is the rapid and long-lasting elimination of the state of hyperthyroidism. The most common treatment options for hyperthyroidism are antithyroid drugs, radioiodine therapy, and surgery. Additionally, minimally invasive procedures such as radiofrequency ablation (RFA) have become available.4 The choice of treatment depends on the severity of the hyperthyroidism, coexisting conditions, contraindications to specific modalities, and the patient’s preferences.4

Medications

Antithyroid drugs can be prescribed to treat the hyperthyroidism caused by toxic nodules, and beta-blockers can help diminish hyperthyroidism-related symptoms (such as increased heart rate) if present.2 However, these drugs only temporarily control thyroid hormone production and prevent complications. If this treatment is suspended, the hyperthyroidism reappears — so these medications are more of a bridge to definitive therapy than a final solution for TNG.2 Antithyroid drugs can also help control hormone production in preparation for definitive treatments such as surgery or radioactive iodine.

Radioiodine therapy

Radioiodine therapy is widely used as a definitive treatment for toxic adenoma and toxic multinodular goiter — in fact, it is the most widely used treatment for toxic nodules in the United States.5 The thyroid takes up almost all the iodine in the body, so when radioactive iodine (I-131) is administered it accumulates in the overactive tissue and destroys it. Toxic nodules can then decrease in size and the symptoms of hyperthyroidism can subside, usually within 2–3 months.

A single dose has been shown to reduce goiter size by up to 40% and usually succeeds in 85–100% of patients with toxic nodular goiter.2 However, a complication known as hypothyroidism (underactive thyroid) can occur in up to 10–20% of patients.2 Possible indications include advanced age, small goiter size, significant coexisting diseases, and prior surgery or scarring of the anterior neck.4 The main contraindications are pregnancy, lactation, and coexisting thyroid cancer.4 Notably, high-activity radioiodine can only decrease the size of large goiters by 30–50% and improves compressive symptoms in 46% of patients, whereas complete surgical removal resolves these symptoms in all patients.4

Surgery

Thyroid surgery is one of the definitive treatments for toxic nodules. A thyroidectomy — surgical removal of all or part of the gland — may be necessary if other treatments are inappropriate or contraindicated. Possible indications include signs of excessive pressure in the neck from an enlarged thyroid (difficulty swallowing or breathing), concern for thyroid cancer, failure of radioiodine therapy, and the need for rapid resolution of the thyrotoxic state.4 Generally, a toxic adenoma involves removal of the entire thyroid lobe containing the lesion, while a total or near-total thyroidectomy is typically performed if nodules are on both sides (toxic multinodular goiter). The risk of treatment failure after either procedure is less than 1%.4 However, surgery carries several important complications that can depend on the extent of the procedure, such as hypothyroidism, hypoparathyroidism, and vocal cord paralysis.2

Non-surgical RFA for toxic thyroid nodules

RFA uses an ultrasound-guided needle electrode to heat and eliminate the activity of the overactive nodule — no surgery, no radioactive iodine, no scar.4

Promising minimally invasive procedures are available for patients with toxic thyroid nodules. If long-term medical treatment, surgery, or radioiodine therapy are inappropriate or contraindicated, a procedure known as radiofrequency ablation (RFA) can be considered as an alternative.4

Radiofrequency ablation is performed by trained interventional radiologists and uses high-frequency alternating current to create focalized heat and destroy tissue. In toxic nodular goiter, an ultrasound-guided needle electrode is used to specifically target and eliminate the activity of the toxic nodule — while the surrounding healthy thyroid is spared.

What the evidence shows. A large retrospective multicenter study validated the safety and efficacy of RFA for autonomously functioning nodules: associated hyperthyroidism improved in all subjects and normalized in 81.8%, with no hypothyroidism or major complication during follow-up.6 In another study comparing RFA to surgery for benign nodules, RFA had fewer complications (1% vs 6% for surgery), no resulting hypothyroidism, similar costs to surgery, and an 85% reduction in nodule size.7

Despite this promising evidence, additional large-scale studies are needed in patients with toxic thyroid nodules before RFA can be recommended as mainstream.4 Given the complexity of the procedure, the use of RFA should be limited to experienced clinicians who have received extensive training in this technique.

Step by step

What happens during toxic nodule RFA?

Confirm the overactive nodule, numb the skin, guide an electrode into the nodule under live ultrasound, then ablate only the overactive tissue — and home the same day.

1

Confirm the toxic nodule

Blood tests confirm hyperthyroidism and a nuclear scan identifies the hyperfunctioning nodule; ultrasound maps it for treatment.

2

Local anesthetic

A local anesthetic numbs the skin over the thyroid. No general anesthesia and no radioactive material are used.

3

Ultrasound-guided electrode

Under real-time ultrasound, a fine needle electrode is placed directly into the toxic nodule.

4

Ablate — home the same day

Focalized heat eliminates the overactive tissue while sparing healthy thyroid. The nodule shrinks over the following months. Outpatient — no incision, no scar.

How it compares

RFA vs. radioactive iodine & surgery

Radioiodine and surgery are effective — but both frequently leave the thyroid underactive. RFA is thyroid-sparing and, in studies, produced no resulting hypothyroidism.2,6,7

Why our specialist?

RFA is only as good as the hand guiding the probe

Here's the uncomfortable truth about RFA: experience alone isn't enough. Ablating only the overactive nodule — millimeters from the nerves and vessels of the neck — means mentally building a 3D picture from a flat 2D ultrasound image, in real time, and steering to it. That spatial gift comes easily to very few. Training and volume sharpen it — but they can't install it.

One of the most experienced & trusted RFA specialists

Some skills can't be taught — only sharpened

Every RFA begins with a problem no diploma solves: the ultrasound screen is flat and two-dimensional, but the thyroid, the nodule, the nerves, and the vessels are arranged in three dimensions — and the needle has to reach exactly the right point in that space, guided by the image alone. Holding that 3D map in your mind while working from a 2D picture is an innate talent that comes easily to very few. You can send a hundred physicians through the same course and only a handful will ever truly see it — the rest are always translating, one step behind the tissue. Experience alone doesn’t close that gap. What experience does — and what six years of post-graduate training and thousands of ablations do — is take a physician who already has the gift and refine it to the point of instinct.

That is the difference at California Thyroid Center. Dr. Atabak Allaei is one of only a few RFA specialists specifically trained in ultrasound-guided procedures, performing over 2,000 procedures yearly across the body. As a double board-certified imaging specialist, he completed six years of post-graduate training specializing in ultrasound-guided procedures and ablations. By comparison, most other RFA providers trained by taking a weekend course and perform only 20–100 ultrasound-guided procedures a year — combining, in many cases, limited volume with a spatial skill that was never their strength to begin with.

2,000+ procedures every year

A volume of ultrasound-guided work that few providers match — versus the 20–100 per year typical of weekend-trained providers.

3D vision from a 2D image

The rare spatial talent RFA demands — seeing the nodule in three dimensions on a flat screen. Experience refines it; it can’t be taught from scratch.

Beyond the thyroid

Ablations of more complex organs — kidney, liver, lung — sharpen the precision brought to every thyroid case.

Frequently asked questions

Toxic thyroid nodule RFA: common questions

What is a toxic thyroid nodule?

A thyroid nodule is an abnormal growth within the thyroid, and about 95% are benign. Some nodules, however, begin autonomously producing excess thyroid hormone. This hyperfunctioning nodule can enlarge the gland (goiter) and cause hyperthyroidism (overactive thyroid). A single autonomous nodule is called a toxic thyroid nodule or toxic adenoma; when more than one is involved it is a toxic multinodular goiter. Toxic nodular goiter (TNG) is the broader term for both.

Toxic nodular goiter is a very common cause of hyperthyroidism — after Graves’ disease, it is the second most common cause of hyperthyroidism in the United States. It is more common in women than in men (older than 40 years), with a palpable-nodule prevalence of about 5–7% in women and 1–2% in men, and it is especially prevalent in adults older than 50.

Diagnosis starts with the signs and symptoms of hyperthyroidism, though some older patients may have atypical symptoms or none at all. It is confirmed with blood tests showing high thyroid hormone levels and a low TSH. A nuclear medicine thyroid scan (iodine-123 or technetium-99m) then locates the overactive tissue: a toxic adenoma appears as a single hyperfunctioning area, while a toxic multinodular goiter appears patchy. Ultrasound is also used to assess and monitor the nodules.

The goal is rapid, long-lasting resolution of hyperthyroidism. Options include antithyroid drugs (a temporary bridge, since hyperthyroidism returns when stopped), radioactive iodine (the most widely used definitive treatment in the US, but it causes hypothyroidism in up to 10–20%), and surgery (thyroidectomy — effective, but with risks such as hypothyroidism, hypoparathyroidism, and vocal cord paralysis). Minimally invasive RFA has also become available as an alternative when medication, surgery, or radioiodine are inappropriate or contraindicated.

Radiofrequency ablation (RFA) is a minimally invasive procedure performed by trained interventional radiologists that uses high-frequency current to create focalized heat and destroy tissue. For a toxic nodule, an ultrasound-guided needle electrode specifically targets and eliminates the activity of the overactive nodule while sparing the surrounding healthy thyroid. It requires no incision, no general anesthesia, and no radioactive material.

A large retrospective multicenter study of autonomously functioning nodules found that hyperthyroidism improved in all subjects and normalized in 81.8%, with no hypothyroidism or major complication during follow-up. In a separate comparison with surgery for benign nodules, RFA had fewer complications (1% vs 6%), no resulting hypothyroidism, costs similar to surgery, and an 85% reduction in nodule size. Larger studies specifically in toxic nodules are still needed, so RFA is best offered by experienced, extensively trained clinicians.

Radioactive iodine and surgery are effective, but both frequently leave the thyroid underactive: radioiodine causes hypothyroidism in up to 10–20%, and thyroidectomy can cause hypothyroidism, hypoparathyroidism, or vocal cord paralysis. RFA is thyroid-sparing — it targets only the overactive nodule — and in studies produced no resulting hypothyroidism, with fewer complications than surgery and no radioactive material. It is outpatient, uses only local anesthesia, and leaves no scar.
