Radiofrequency ablation gains favor for thyroid nodules in U.S.
And in one case, a hospital has taken the unique step of forming a multidisciplinary thyroid nodule RFA tumor board, which helps in the often tricky decision-making process that is involved.
“Our multidisciplinary RFA tumor board has been invaluable in this process, and it is the only one of its kind in the nation that I’m aware of,” James Lim, MD, of the Division of Surgical Oncology, Thyroid, and Parathyroid Center at Oregon Health Sciences University (OHSU), told this news organization.
Dr. Lim reports receiving referrals from “all avenues, some from thyroid specialists and others from nonthyroid specialists such as primary care practitioners or patient self-referrals.”
“Because of this, our centralized process of multidisciplinary review ensures that each patient is evaluated thoroughly through each thyroid specialists’ lens to optimize patient outcomes,” noted Dr. Lim, an assistant professor of endocrine surgery.
The RFA tumor board consists of experts in all specialties involved in thyroid nodule assessment and treatment, including surgeons, interventional radiologists, and endocrinologists.
Just because you can, doesn’t mean you should
However, there should be some caution that although there is enthusiasm regarding this noninvasive alternative to surgery, there is another option, that of mere observation, which is appropriate in many cases of thyroid nodules and should not be overlooked.
“For a number of reasons, the key to keep in mind is that, just because we can do something doesn’t mean we should,” Michael Singer, MD, director of the Division of Thyroid & Parathyroid Surgery, Department of Otolaryngology – Head and Neck Surgery, at the Henry Ford Health System, Detroit, said in an interview.
While emphasizing that he believes RFA to be a promising technology that will likely benefit patients in the future, Dr. Singer voiced concern about the approach becoming an easy choice – particularly if profit is to be had – when observation is a clear alternative. “If RFA becomes seen as an opportunity to create revenue, potential conflicts of interest may arise,” he said.
“As it is not a major procedure with a dramatic risk profile, my concern is that some clinicians [could] adopt the attitude of ‘Why not do it?’ even when the indication is minimal or nonexistent,” he added.
Dr. Lim said he agrees that “any new medical technology requires thoughtful evaluation and appropriate patient selection in order to ensure optimal patient outcomes.”
That’s where the tumor board has been especially beneficial.
“We have found great benefit in reviewing potential RFA cases in a multidisciplinary fashion within our tumor board and would recommend other institutions to consider it,” he noted. In the absence of a tumor board, “at a minimum, a thyroid specialist should be involved in the evaluation of a potential thyroid RFA patient prior to ablation treatment,” he advised.
Tumor board was able to identify a small subset of patients for surgery
In his research presented at the 90th Annual Meeting of the American Thyroid Association (ATA), Dr. Lim and colleagues evaluated the tumor board’s efficacy in altering diagnosis and treatment plans in a retrospective review of cases presented to the board for RFA consideration since its inception in July 2020 through June 2021.
Over the study period, 65 patients with biopsy-proven benign thyroid nodules were newly referred for RFA, with 58 referred for mass effect symptoms and seven for autonomous function.
After the multidisciplinary review, about half of the cases, 37 (56.9%), were approved for RFA.
Of the remainder, 22 (33.8%) were determined to need additional studies, just two (3.0%) were recommended for surgery, and four (6.2%) were recommended to not receive any intervention.
Of the 22 cases recommended for additional studies, 15 were subsequently recommended for RFA and four were recommended to receive surgery due to suspicious clinical findings.
Of those that underwent surgery, two showed thyroid cancer on final pathology.
Among the nodules recommended to RFA, the average nodule volume was 15.1 mL, whereas the average volume for those recommended for surgery was 40.9 mL (P = .08).
No significant complications occurred among patients that underwent RFA or those who had surgery.
“The tumor board’s multidisciplinary review was able to identify high-risk features in some patients with benign biopsies. This led to a change in recommendation from RFA to surgery for possible malignancy in a small subset of patients,” Dr. Lim noted.
In a separate analysis, Dr. Lim and colleagues reported that, among patients treated with RFA (with a mean baseline nodule volume of 11.9 mL), mean nodule volume was 6.4 mL after 1 month, 4.5 mL after 3 months, and 3.8 mL at 6 months, which were all significantly reduced versus baseline (P < .001). Similar improvements were also reported in symptom and cosmetic scores at each timepoint (all P < .001).
There were no cases of postprocedural hypothyroidism or symptomatic thyrotoxicosis.
Underlining that patients can expect noticeable improvement in symptom scores by their 30-day visit, Dr. Lim noted that patients should be warned of some early swelling.
“It is important to inform patients that they may have swelling of their treated nodule immediately after the procedure, but this should subside within a few days,” he said.
Outpatient RFA safe and efficacious
In a separate study also presented at the meeting, three practitioners described their experiences with RFA in their outpatient thyroid practices in San Antonio; Santa Monica, California; and Gettysburg, Pennsylvania.
Overall, there were 68 cases involving benign, class II thyroid nodules, and the authors reported average procedure times of under an hour, with actual RFA time varying from 7 to 22 minutes.
Of note, for nodules larger than 4.5 cm, two procedures were necessary to achieve desired results.
Excluding the larger nodules requiring more than one procedure, there was an average decrease in nodule size of 48% at 1 month and a decrease of 82% after 3 months in more than 80% of cases.
None of the cases required surgery. There were no major complications, and all patients had preserved baseline thyroid function.
“This preliminary study of 68 patients shows how thyroid RFA is safe and efficacious when performed in an endocrine outpatient office practice,” Kathleen Hands, MD, of the Thyroid Center of South Texas, and coauthors concluded.
Insurance coverage an issue in U.S.
Among much larger studies demonstrating the safety and efficacy of RFA for benign nodules, a study of 450 Chinese patients published in January showed RFA to be superior to conventional thyroidectomy in terms of patient satisfaction, postoperative quality of life, and shorter hospital stay, although the caveat was it took longer to achieve nodule volume reduction.
But if RFA use is to become more widespread in the United States, a key obstacle is that insurance companies generally do not cover the procedure. Although patients in Dr. Lim’s analyses did have coverage, it didn’t come easily, he said.
“Thankfully, all of our patients have been approved by insurance, and no one has had to pay by themselves, but this has sometimes required multiple appeals to the insurance company,” Dr. Lim said.
“The American Association of Endocrine Surgeons and Society of Interventional Radiology are both working towards getting this valuable treatment more readily accepted by more insurance companies,” he said.
Dr. Lim and Dr. Singer have reported no relevant financial relationships.

Adding statins to steroids in thyroid eye disease improves outcomes
Treatment of Graves’ orbitopathy with statins in combination with glucocorticoids shows benefits among people with – and even without – high cholesterol, results from a new randomized clinical trial show.
“Our results [indicate] that adding atorvastatin to intravenous glucocorticoids seems to potentiate the effects of glucocorticoids,” senior author Michelle Marino, MD, associate professor of endocrinology in the department of clinical and experimental medicine at the University of Pisa, Italy, told this news organization.
“At least in hypercholesterolemic patients with moderate to severe and active Graves’ orbitopathy, atorvastatin should be considered in addition to intravenous glucocorticoids,” Dr. Marino said.
The study was presented by first author Giulia Lanzolla, MD, also of the University of Pisa and University Hospital of Pisa, at the virtual annual meeting of the American Thyroid Association.
Hypercholesterolemia, well known to promote systemic inflammation, has been previously linked to Graves’ orbitopathy, and the use of statins has also been shown to possibly provide a protective effect in the risk of developing the thyroid eye disease.
Furthermore, patients with Graves’ orbitopathy and high cholesterol levels, compared with those with normal cholesterol, have been shown to have poorer responses to treatment with glucocorticoids, which have long been the first line of treatment.
Asked for comment on the findings, Marius Stan, MD, a consultant in the division of endocrinology, diabetes, metabolism, and nutrition, Mayo Clinic, Rochester, Minn., said he didn’t think the outcome measure used – a composite of a variety of measures of thyroid eye disease – was best to truly understand the benefits.
Statins for Graves’ orbitopathy (STAGO) study details
For a better understanding of the effects with and without the addition of statins in a randomized trial, Dr. Lanzolla and colleagues enrolled 88 patients with high cholesterol and moderate to severe active Graves’ orbitopathy in the phase 2 STAGO trial.
Patients were randomized to two groups of 44 patients each to receive treatment either with intravenous (IV) methylprednisolone at 500 mg per week for 6 weeks, followed by 250 mg per week for another 6 weeks, in combination with atorvastatin 20 mg daily for 12 weeks, or methylprednisolone alone for 12 weeks.
The primary endpoint was a composite of Graves orbitopathy outcomes and included measures of exophthalmos, clinical activity score, eyelid aperture, diplopia, and visual acuity, as assessed in the modified intention-to-treat population.
The trial met the primary composite endpoint, with 51.2% of those treated with statins achieving the outcome (21 of 41) versus 28.2% (11 of 39) of those treated with glucocorticoids alone (odds ratio, 2.76; P = .03).
The study also achieved secondary outcomes, with 43.9% in the statin group having a response to treatment at 12 weeks versus 23% in the glucocorticoid group (OR 2.60; P = .05). The statin group also had a greater improvement in quality of life measures (P = .03).
The glucocorticoid-only group meanwhile had a significantly greater rate of Graves orbitopathy relapse at 24 weeks, with six relapses versus none in the statin group (15.3% vs. 0.0%; OR 0.06; P = .01).
There were no significant differences in low-density lipoprotein (LDL) cholesterol between those who did and did not respond to treatment in the statin group.
The most likely explanation for those findings is that “atorvastatin acts through its pleiotropic action, resulting in an anti-inflammatory effect,” Dr. Marino said.
“In addition, the effect may be related to the capability of statins to inhibit fibroblast proliferation,” Dr. Marino added.
“Total cholesterol had a behavior similar to LDL cholesterol, [while] HDL cholesterol did not change across the study.”
There were no major adverse events related to atorvastatin, with one patient in each group requiring treatment discontinuation.
In the rapidly evolving landscape of treatments for Graves’ orbitopathy, including the recent Food and Drug Administration approval for teprotumumab in thyroid eye disease, the potential role of statins remains to be seen, Dr. Marino noted.
“Graves’ orbitopathy is a rather complex disease, and in its mild to moderate forms it is very rare for a patient to require only a single treatment,” Dr. Marino explained. “Rehabilitative surgery is needed quite often once the disease is inactive.”
The authors noted that a composite overall Graves’ orbitopathy outcome was used as the primary endpoint because the alternative of a change in single eye features may not reflect a true modification of Graves’ orbitopathy and could be affected by a number of unrelated factors.
“By contrast, the composite evaluation offers a more realistic picture,” the authors wrote in the article, which was published in The Lancet Diabetes and Endocrinology.
Composite outcome not best way of assessing effects of statins
Dr. Stan extrapolated on his criticism of the trial.
“The study has interesting results but fails to show that any particular eye feature is benefited by the combination therapy, showing only the composite outcome to be improved,” he told this news organization.
“Unfortunately, that is hard to extrapolate to patient care, where one or another of Graves’ orbitopathy features are present and are the intended target of therapy,” he said.
Dr. Stan added that IV glucocorticoids are meanwhile also changing the landscape of treatment of thyroid eye disease.
“This ... current plan is to recommend a more individualized approach, depending on what is the main problem for that thyroid eye disease case,” he explained.
Dr. Marino noted that the authors are planning a double-blind, placebo-controlled phase 3 clinical trial of the statin/glucocorticoid combination to include patients regardless of their cholesterol levels.
The study received funding from Associazione Allievi Endocrinologia Pisana. The authors have reported no relevant financial relationships. Dr. Stan is on the advisory board for Horizon Pharma/Immunovant and provides general consulting for VasaraGen/Septerna and ValenzaBio/Medicxi.

The primary endpoint was a composite of Graves orbitopathy outcomes and included measures of exophthalmos, clinical activity score, eyelid aperture, diplopia, and visual acuity, as assessed in the modified intention-to-treat population.
The trial met the primary composite endpoint, with 51.2% of those treated with statins achieving the outcome (21 of 41) versus 28.2% (11 of 39) of those treated with glucocorticoids alone (odds ratio, 2.76; P = .03).
The study also achieved secondary outcomes, with 43.9% in the statin group having a response to treatment at 12 weeks versus 23% in the glucocorticoid group (OR 2.60; P = .05). The statin group also had a greater improvement in quality of life measures (P = .03).
The glucocorticoid-only group meanwhile had a significantly greater rate of Graves orbitopathy relapse at 24 weeks, with six relapses versus none in the statin group (15.3% vs. 0.0%; OR 0.06; P = .01).
There were no significant differences in low-density lipoprotein (LDL) cholesterol between those who did and did not respond to treatment in the statin group.
The most likely explanation for those findings is that “atorvastatin acts through its pleiotropic action, resulting in an anti-inflammatory effect,” Dr. Marino said.
“In addition, the effect may be related to the capability of statins to inhibit fibroblast proliferation,” Dr. Marino added.
“Total cholesterol had a behavior similar to LDL cholesterol, [while] HDL cholesterol did not change across the study.”
There were no major adverse events related to atorvastatin, with one patient in each group requiring treatment discontinuation.
In the rapidly evolving landscape of treatments for Graves’ orbitopathy, including the recent Food and Drug Administration approval for teprotumumab in thyroid eye disease, the potential role of statins remains to be seen, Dr. Marino noted.
“Graves’ orbitopathy is a rather complex disease, and in its mild to moderate forms it is very rare for a patient to require only a single treatment,” Dr. Marino explained. “Rehabilitative surgery is needed quite often once the disease is inactive.”
The authors noted that a composite overall Graves’ orbitopathy outcome was used as the primary endpoint because the alternative of a change in single eye features may not reflect a true modification of Graves’ orbitopathy and could be affected by a number of unrelated factors.
“By contrast, the composite evaluation offers a more realistic picture,” the authors wrote in the article, which was published in The Lancet Diabetes and Endocrinology.
Composite outcome not best way of assessing effects of statins
Dr. Stan extrapolated on his criticism of the trial.
“The study has interesting results but fails to show that any particular eye feature is benefited by the combination therapy, showing only the composite outcome to be improved,” he told this news organization.
“Unfortunately, that is hard to extrapolate to patient care, where one or another of Graves’ orbitopathy features are present and are the intended target of therapy,” he said.
Dr. Stan added that IV glucocorticoids are meanwhile also changing the landscape of treatment of thyroid eye disease.
“This ... current plan is to recommend a more individualized approach, depending on what is the main problem for that thyroid eye disease case,” he explained.
Dr. Marino noted that the authors are planning a double-blind, placebo-controlled phase 3 clinical trial of the statin/glucocorticoid combination to include patients regardless of their cholesterol levels.
The study received funding from Associazione Allievi Endocrinologia Pisana. The authors have reported no relevant financial relationships. Dr. Stan is on the advisory board for Horizon Pharma/Immunovant and provides general consulting for VasaraGen/Septerna and ValenzaBio/Medicxi.
